NEW QUESTION # 34
After deploying a new API, the security team must identify the components of the application that are exposed to the internet and whether there are application authentication risks. Which technology must be deployed to discover the applications services and monitor for authentication issues?
- A. Cloud Security Posture Management
- B. Cloud Workload Protection
- C. API trace analysis
- D. secret scanning
Answer: C
Explanation:
API trace analysis allows the security team to map out which API endpoints are exposed to the internet and to detect authentication risks. By tracing API calls, it identifies exposed services, monitors traffic flow, and highlights weaknesses in authentication or authorization mechanisms.
NEW QUESTION # 35
A manufacturing company experienced a security breach that resulted in sales data being compromised. An engineer participating in the investigation must identify who logged into the sales system during the affected period. Which approach must be used to gather the information?
- A. PKI
- B. NACM
- C. AAA
- D. SNMP
Answer: C
Explanation:
AAA (Authentication, Authorization, and Accounting) provides accounting logs that record who logged in, when, and from where. During an investigation, these logs allow the security team to trace user logins to the sales system and identify who accessed it during the breach period.
NEW QUESTION # 36
A restaurant distribution center recently suffered a password spray attack targeting the Cisco Secure Firepower Threat Defense VPN headend. The attack attempts to gain unauthorized access by trying common passwords across many accounts. The attack poses a significant security threat to the organization's remote access infrastructure. To enhance the security of the VPN setup and minimize the risk of similar attacks in the future, the IT security team must implement effective mitigation measures. Which technique effectively reduces the risk of this type of attack?
- A. Implement an access list to block addresses from the previous password spray attack.
- B. Enable AAA authentication for the DefaultWEBVPN and DefaultRAGroup Connection Profiles.
- C. Disable group aliases in the connection profiles.
- D. Change the AAA authentication method from RADIUS to TACACS+.
Answer: B
Explanation:
In the context of Designing Cisco Security Infrastructure, protecting Remote Access VPN (RAVPN) against brute-force and password spray attacks is a critical objective. On Cisco Firepower Threat Defense (FTD) and Adaptive Security Appliance (ASA) platforms, theDefaultWEBVPNGroupandDefaultRAGroupare the landing points for any connection request that does not specify a valid Group Alias or Group URL. Attackers frequently target these default profiles because they are often left with "None" as the authentication method, allowing the attacker to probe for valid usernames without immediate rejection.
By selectingOption D, the security designer ensures that any attempt to access the VPN via these default profiles requires valid AAA credentials. According to Cisco's hardened design guides, it is best practice to point these default profiles to a "sinkhole" AAA server or a local database with no users. This forces the password spray attack to fail at the initial authentication phase before any sensitive information is leaked or unauthorized access is granted. While Option A (ACLs) provides a temporary fix, it is ineffective against distributed attacks using rotating IP addresses. Option B (Disabling aliases) is a good obfuscation technique but doesn't stop an attacker from hitting the default profile. Option D provides a structural mitigation that aligns with theCisco SAFEarchitectural principle of reducing the attack surface by securing every possible entry vector into the private infrastructure.
NEW QUESTION # 37
Which two metrics are important for evaluating the performance of automated security response workflows? (Choose two.)
- A. CPU temperature
- B. Mean Time to Detect (MTTD)
- C. Mean Time to Respond (MTTR)
- D. VLAN propagation speed
Answer: B,C
Explanation:
MTTD measures how quickly incidents are detected, and MTTR measures how quickly they are resolved. Together, they indicate the effectiveness of automated security response workflows.
NEW QUESTION # 38
Which two solutions help ensure consistent policy enforcement across multi-cloud workloads?
(Choose two.)
- A. Static IP routing
- B. Cisco Secure Workload (Tetration)
- C. SNMP traps
- D. Cloud-delivered Firewall (CDFW)
Answer: B,D
Explanation:
Cisco Secure Workload provides workload visibility and policy enforcement across environments, while cloud-delivered firewalls apply consistent security policies across multiple cloud platforms.
NEW QUESTION # 39
A product manager is focused on maintaining the security integrity of a microservice-based application as new features are developed and integrated. To ensure that known software vulnerabilities are not introduced into the product, it is crucial to implement a robust application security technique. The technique must be applied during the build phase of the software development lifecycle, which allows the team to proactively identify and address vulnerability risks before deployment. Which application security technique must be applied to accomplish the goal?
- A. container scanning
- B. infrastructure as code scanning
- C. Open API specification analysis
- D. secret detection
Answer: A
Explanation:
In a microservices-based architecture, applications are typically packaged into containers to ensure consistency across different environments. According to theDesigning Cisco Security Infrastructure (SDSI) objectives, securing the software development lifecycle (SDLC) requires integrating security checks as far
"left" as possible.Container scanningis the specific technique used during the build phase to inspect container images for known software vulnerabilities (CVEs) within the bundled libraries, binaries, and dependencies.
When a developer initiates a build, the container scanning tool cross-references the layers of the image against vulnerability databases. If a high-risk vulnerability is detected in a base image or a third-party library, the build can be automatically failed, preventing the vulnerable code from ever reaching the registry or production environment. This directly addresses the product manager's goal of ensuring known vulnerabilities are not introduced. WhileSecret Detection(Option A) is vital for finding leaked API keys or passwords, and Infrastructure as Code (IaC) scanning(Option C) ensures the environment configuration is secure, neither specifically targets the software vulnerabilities within the application package itself. Similarly,Open API specification analysis(Option D) focuses on the contract and security of the interface rather than the underlying software vulnerabilities. By implementing container scanning, organizations align with Cisco's DevSecOps framework, which emphasizes automated, policy-driven security within the CI/CD pipeline to maintain the integrity of cloud-native applications.
NEW QUESTION # 40
Which design policy addresses harmful content creation by generative AI?
- A. watermarking
- B. quantum resistant encryption
- C. human in the loop
- D. retrieval augmented generation
Answer: A
Explanation:
Watermarking is a generative AI design policy that embeds hidden identifiers into AI-generated content. This helps address the risk of harmful content creation by enabling traceability and accountability, making it easier to detect and regulate malicious or misleading AI outputs.
NEW QUESTION # 41
An employee of a pharmaceutical company accidentally checked in code that contains AWS secret keys to a public GitHub repository, which exposes production resources to attackers.
Which mitigation strategy must a security engineer recommend to prevent future reoccurrence?
- A. Configure a SCM precommit hook.
- B. Implement a more granular port security strategy.
- C. Implement a phishing education campaign.
- D. Add a web application firewall.
Answer: A
Explanation:
An SCM (Source Code Management) precommit hook scans code for sensitive information such as AWS keys before it is committed. This prevents developers from accidentally pushing secrets to public repositories, protecting production resources from exposure.
NEW QUESTION # 42
A software development company uses multiple cloud providers to host the applications. The company is designing a scalable firewall solution that must meet the requirements:
- Consistent security policies across multiple cloud environments.
- Centralized visibility and management.
- Scalability to accommodate different cloud platforms.
Which type of firewall meets the requirements?
- A. distributed firewall
- B. host-based firewall
- C. traditional firewall
- D. zone-based firewall
Answer: A
Explanation:
A distributed firewall is designed for multi-cloud and hybrid environments. It ensures consistent security policies across multiple platforms, offers centralized visibility and management, and scales seamlessly with workloads across different cloud providers. This directly meets the requirements of the scenario, unlike traditional or host-based solutions that lack centralized scalability across multiple clouds.
NEW QUESTION # 43
A financial company is focused on proactively protecting sensitive data stored on the devices.
The company recognizes the potential risks associated with lost or stolen devices and they want a solution to ensure that if unauthorized user access the device, the data it contains is not accessible or misused. The solution includes implementing a strategy that renders data unreadable without user authentication. Which solution meets the requirement?
- A. Apply GPS tracking.
- B. Install Kensington Lock.
- C. Use a BIOS password.
- D. Implement data encryption on disk.
Answer: D
Explanation:
Disk encryption ensures that data stored on devices is unreadable without proper authentication.
If a device is lost or stolen, unauthorized users cannot access or misuse the data, since encryption protects the contents until the legitimate user provides credentials.
NEW QUESTION # 44
A company hosted multiple applications in the Kubernetes environment, using the naming app01, app02, and so on. An app01 user could access app02 data because no security measures are implemented. The administrator decided to place each application within a separate namespace and ensure that the namespaces are completely isolated and cannot communicate with each other. Which solution must be used to accomplish the task?
- A. Gateway
- B. NetworkPolicy
- C. RoleBinding
- D. HTTPRoute
Answer: B
Explanation:
In a Kubernetes environment,Namespacesprovide a logical partition for resources but do not, by default, provide network isolation. To prevent "app01" from communicating with "app02," aNetworkPolicymust be implemented. NetworkPolicies act as the Layer 3/4 distributed firewall for the cluster, allowing administrators to define explicit rules for ingress and egress traffic between pods and namespaces.
To achieve complete isolation, a common design pattern is to implement a "deny-all" default policy for each namespace and then explicitly allow only necessary traffic. This aligns with theCisco SAFEarchitectural principle of micro-segmentation. WhileRoleBinding(Option B) manages permissions for the Kubernetes API (who can create or delete pods), it does not control the actual network traffic between those pods.HTTPRoute (Option A) andGateway(Option D) are components of the Kubernetes Gateway API used for managing external traffic routing and load balancing, rather than internal pod-to-pod isolation. By deploying NetworkPolicies, the administrator ensures that the "blast radius" of a compromised application is contained within its own namespace, fulfilling a core objective of securing cloud-native application infrastructure.

NEW QUESTION # 45
A manufacturing company experienced a security breach that resulted in sales data being compromised. An engineer participating in the investigation must identify who logged into the sales system during the affected period. Which approach must be used to gather the information?
- A. PKI
- B. NACM
- C. AAA
- D. SNMP
Answer: C
Explanation:
In the aftermath of a security breach, forensic investigators rely on theAccountingportion ofAAA (Authentication, Authorization, and Accounting)to reconstruct a timeline of events. While Authentication verifies identity and Authorization defines permissions, Accounting is the specific framework used to track user activity, including login/logout times and the specific commands executed during a session.
According to Cisco Security Infrastructure design objectives, implementing a centralized AAA solution (such asCisco Identity Services Engine (ISE)or a TACACS+/RADIUS server) is critical for accountability. In this scenario, the engineer would query the AAA logs to identify exactly "who" accessed the sales system during the compromise period.SNMP(Option A) is primarily for network monitoring and performance data, not granular user access logs.NACM(Option B) is an access control model for NETCONF but doesn't provide the broad auditing required here.PKI(Option D) provides the certificates used for digital signatures and encryption but does not log the historical "session" data needed for the investigation. Therefore, AAA is the fundamental architectural requirement for ensuring non-repudiation and providing the audit trail necessary to satisfy risk management and incident response requirements.

NEW QUESTION # 46
A security engineer on an application design team must choose a framework of attack patterns to evaluate during threat modeling. Which framework provides the common set of attacks?
- A. MITRE CAPEC
- B. SOC2
- C. Cisco SAFE
- D. GDPR
Answer: A
NEW QUESTION # 47
An employee of a pharmaceutical company accidentally checked in code that contains AWS secret keys to a public GitHub repository, which exposes production resources to attackers. Which mitigation strategy must a security engineer recommend to prevent future reoccurrence?
- A. Configure a SCM precommit hook.
- B. Implement a more granular port security strategy.
- C. Implement a phishing education campaign.
- D. Add a web application firewall.
Answer: A
Explanation:
Accidental exposure of sensitive credentials, such as API keys or AWS secrets, is a major risk in modern DevOps environments. To prevent such incidents from occurring, the most effective technical control is the implementation of aSource Code Management (SCM) precommit hook. A precommit hook is a script that runs locally on a developer's machine before a commit is finalized and pushed to a remote repository.
According to Cisco's DevSecOps design principles, precommit hooks can be configured to scan the code for specific patterns that resemble secrets (e.g., regex for AWS Access Key IDs). If the scanner detects a secret, it automatically aborts the commit, forcing the developer to remove or properly encrypt the sensitive data before the code can leave their local machine. This provides an immediate "shift-left" safety net that stops the leak at the source.
While aWeb Application Firewall (WAF)(Option A) protects against external attacks andPort Security (Option B) manages Layer 2 access, neither can prevent a developer from pushing code to GitHub. Aphishing education campaign(Option C) is beneficial for general security awareness but does not provide the automated, technical enforcement required to block credential leakage. By configuring precommit hooks, the pharmaceutical company establishes a proactive defense mechanism that significantly reduces the risk of credential exposure and aligns with the automation objectives of the Cisco SDSI curriculum.
NEW QUESTION # 48
After a recent security breach, a financial company is reassessing their overall security posture and strategy to better protect sensitive data and resources. The company already deployed on-premises next-generation firewalls at the network edge for each branch location. Security measures must be enhanced at the endpoint level. The goal is to implement a solution that provides additional traffic filtering directly on endpoint devices, thereby offering another layer of defense against potential threats. Which technology must be implemented to meet the requirement?
- A. web application firewall
- B. host-based firewall
- C. distributed firewall
- D. traditional firewall
Answer: B
Explanation:
When moving security closer to the data, the endpoint becomes the final perimeter. Ahost-based firewallis a software component that runs directly on the endpoint's operating system (Windows, macOS, or Linux).
While the company already has Next-Generation Firewalls (NGFWs) at the network edge, those devices cannot protect endpoints from threats originating within the same local network segment (East-West traffic) or when the device is used outside the corporate office.
Implementing a host-based firewall provides a critical layer ofdefense-in-depth. It allows security administrators to enforce strict inbound and outbound traffic rules based on applications and services specific to that device. For example, it can prevent a compromised laptop from scanning other devices on a public Wi- Fi network. In the Cisco ecosystem, this is often achieved through theCisco Secure Client(AnyConnect) using theNetwork Visibility Module (NVM)or integrated endpoint security suites.
While aDistributed Firewall(Option C) is used for micro-segmentation within data centers/clouds and aWeb Application Firewall (WAF)(Option B) protects servers from web-based attacks, only a host-based firewall meets the requirement for traffic filtering directly on the diverse array of endpoint devices. This approach ensures that even if the network edge is bypassed, the individual host remains hardened against lateral movement and unauthorized communication.
NEW QUESTION # 49
An oil and gas company recently faced a security breach when an employee's notepad, which contained critical login credentials, was stolen. The incident led to unauthorized access to a user account, which posed a significant risk to sensitive company data and operations. The company wants to adopt a security measure that enhances user account protection. Which action must be taken to prevent breaches like this from happening in the future?
- A. Implement MFA
- B. Update the RADIUS server.
- C. Implement single sign-on.
- D. Configure a password expiration policy.
Answer: A
Explanation:
The scenario described-where physical theft of written credentials led to a breach-is a classic failure of single-factor authentication. To mitigate this risk, the company must implementMulti-Factor Authentication (MFA). MFA requires users to provide two or more verification factors to gain access to a resource, typically categorized as something you know (password), something you have (a smartphone or hardware token), or something you are (biometrics).
According to Cisco Security Infrastructure design best practices, MFA (such asCisco Duo) ensures that even if an attacker possesses valid credentials (the "something you know" from the stolen notepad), they cannot gain access without the second factor (the "something you have"). This effectively neutralizes the threat of stolen passwords.Single Sign-On (SSO)(Option B) improves user experience and centralizes management but does not, by itself, stop an attacker who has the master password.Updating the RADIUS server(Option C) is a maintenance task that doesn't change the authentication logic, and apassword expiration policy(Option D) would only limit the "shelf life" of the stolen credentials rather than preventing their initial use. MFA is the most robust architectural control for enhancing identity security and is a core pillar of a Zero Trust framework.

NEW QUESTION # 50
An administrator at a large university wants to ensure that the new employees have the right level of access when they are onboarded. The administrator asked the team to configure the cloud environment and ensure that new employees have the appropriate access based on their roles and responsibilities. Which technique must be recommended to ensure the right level of access?
- A. security groups
- B. VPN
- C. identity access management
- D. network access control list
Answer: C
Explanation:
In a modern cloud and campus environment, managing the lifecycle of an identity is the cornerstone of a secure architecture.Identity and Access Management (IAM)is the comprehensive framework of policies and technologies that ensures the right individuals have the appropriate access to technology resources. According to the Cisco SDSI objectives, IAM is the primary mechanism used to transition from manual, error-prone onboarding to a policy-driven approach based onroles and responsibilities.
IAM solutions allow administrators to define digital identities and associate them with specific roles (Role- Based Access Control). When a new employee is onboarded, the IAM system automatically provisions access to the necessary cloud applications and data based on their department or job function. This ensures the principle ofleast privilegeis maintained from day one. WhileSecurity Groups(Option B) andNetwork Access Control Lists (ACLs)(Option D) are important technical controls for filtering traffic at the network layer, they do not manage the identity lifecycle or the complex mapping of users to application permissions. A VPN(Option C) provides a secure tunnel for remote access but does not definewhata user can do once they are inside the network. IAM provides the central control plane for identity-centric security, which is essential for a large university environment with high user turnover and diverse access requirements.

NEW QUESTION # 51
An IT company operates an application in a SaaS model. The administrative tasks, such as customer onboarding, within the application must be restricted to users who are on the corporate network where admins can access those functions via a web browser or a smartphone application. Which application technology must be used to provide granular control based on function?
- A. security group
- B. VPC
- C. RBAC
- D. Service Mesh
Answer: C
Explanation:
The requirement to restrict administrative tasks like "customer onboarding" to specific users based on their job function is a classic use case forRole-Based Access Control (RBAC). In the context of application security design, RBAC is the mechanism that maps a user's identity to a specific set of permissions within the application.
According to Cisco Security Infrastructure principles, RBAC ensures the principle ofleast privilegeby ensuring that an "Admin" role has access to onboarding functions, while a "Support" or "Standard User" role does not. This control is independent of the network layer and is enforced at the application or identity provider level. While aVPC(Option A) orSecurity Groups(Option C) provide network-layer isolation and can ensure the user is on the corporate network (by filtering IP ranges), they cannot distinguish between differentfunctionsoractionsperformed within the application once the connection is established. AService Mesh(Option D) is used for microservices communication and can provide some authorization, but RBAC is the primary architectural approach for defining "who can do what" within an application interface.
Implementing RBAC allows the SaaS provider to secure sensitive administrative workflows, ensuring that only authorized personnel can modify customer data or system configurations.
