NEW QUESTION # 166
A cloud administrator is looking at the company's cloud services bill for the previous month. The administrator notices on the billing dashboard that certain resources are not being billed to any particular department. Which of the following actions will help correct this billing issue?
- A. Check the utilization of the resources.
- B. Modify the tags for all the unmapped resources.
- C. Modify the chargeback details of the consumer.
- D. Add the resources to the consumer monitoring group.
Answer: B
Explanation:
Tags are metadata or labels that can be attached to cloud resources, such as VMs, storage, or networks. Tags can help organize, identify, and manage cloud resources, as well as track their usage and costs. Tags can also be used to implement chargeback or showback policies, which are methods of allocating the cloud services bill to different departments or consumers based on their consumption of resources .
A cloud administrator can modify the tags for all the unmapped resources to correct the billing issue. By adding or updating the tags with the relevant department or consumer name, the administrator can ensure that the resources are billed to the correct entity. The administrator can also use the tags to filter, sort, or group the resources on the billing dashboard, and generate reports or alerts based on the tags .
Checking the utilization of the resources may help identify the purpose or owner of the resources, but it will not help correct the billing issue. The administrator still needs to modify the tags for the resources to assign them to the appropriate department or consumer.
Modifying the chargeback details of the consumer may help adjust the billing rate or method for a specific consumer, but it will not help correct the billing issue. The administrator still needs to modify the tags for the resources to associate them with the consumer.
Adding the resources to the consumer monitoring group may help monitor the performance or availability of the resources for a specific consumer, but it will not help correct the billing issue. The administrator still needs to modify the tags for the resources to link them with the consumer.
NEW QUESTION # 167
A systems administrator wants to restrict access to a set of sensitive files to a specific group of users. Which of the following will achieve the objective?
- A. Configure data loss prevention in the environment
- B. Implement a HIPS solution on the host
- C. Add audit rules on the server
- D. Change tine permissions and ownership of the files
Answer: D
Explanation:
The best way to restrict access to a set of sensitive files to a specific group of users is to change the file permissions and ownership of the files. File permissions and ownership are attributes that determine who can read, write, execute, or modify the files. By changing the file permissions and ownership, the systems administrator can grant or deny access to the files based on the user identity or group membership. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 2.0 Security, Objective 2.3 Given a scenario, implement appropriate access control measures for a cloud environment.

- A. Memory on the VM
- B. Firewall on the VM
- C. vGPU performance on the VM
- D. Logs on the VM
Answer: D
Explanation:
Checking the logs on the VM is the next step that the administrator should take if the cloud SQL database has stopped running after an update deployment. Logs are records of events and activities that occur on a system or application. Logs can provide useful information for troubleshooting and identifying the root cause of an issue. The administrator should look for any errors, warnings, or messages that indicate what happened to the SQL database service and why it stopped running.

NEW QUESTION # 170
A systems administrator is troubleshooting performance issues with a Windows VDI environment. Users have reported that VDI performance is very slow at the start of the workday, but the performance is fine during the rest of the day. Which of the following is the MOST likely cause of the issue? (Choose two.)
- A. License issues
- B. CPU oversubscription
- C. Affinity rule
- D. RAM usage
- E. Disk I/O limits
- F. Insufficient GPU resources
Answer: B,E
Explanation:
Disk I/O limits are restrictions or controls that limit the amount of disk input/output operations per second (IOPS) that a VM can perform on a storage device or system. CPU oversubscription is a situation where more CPU resources are allocated to VMs than are physically available on the host or server. Disk I/O limits and CPU oversubscription are most likely to cause VDI performance being very slow at the start of the workday, but fine during the rest of the day, as they can create bottlenecks or contention for disk and CPU resources when multiple users log in or launch their VDI sessions at the same time, resulting in increased latency or reduced throughput for VDI operations. Reference: CompTIA Cloud+ Certification Exam Objectives, page 9, section 1.4
NEW QUESTION # 171
Which of the following enables CSPs to offer unlimited capacity to customers?
- A. Agile project management
- B. Economies of scale
- C. Adequate budget
- D. Global data center distribution
Answer: B
Explanation:
Explanation
The correct answer is C. Economies of scale.
Economies of scale are the cost advantages that CSPs can achieve by increasing the size and scale of their operations. By spreading the fixed costs of infrastructure, software, and personnel over a larger customer base and data volume, CSPs can reduce the average cost per unit of service and offer unlimited capacity to customers at competitive prices1.
Adequate budget is not a sufficient condition for offering unlimited capacity, as CSPs still need to optimize their resource utilization and efficiency to meet the growing demand for data storage and processing.
Global data center distribution is a strategy that CSPs use to improve their service availability, reliability, and performance by locating their servers closer to their customers and reducing network latency. However, this does not necessarily imply unlimited capacity, as CSPs still need to manage the trade-offs between data center size, cost, and power consumption.
Agile project management is a methodology that CSPs use to deliver their services faster, better, and cheaper by adopting iterative, incremental, and collaborative approaches. However, this does not directly affect their capacity, as CSPs still need to scale their infrastructure and software to handle the increasing data load.
NEW QUESTION # 172
A company is preparing a hypervisor environment to implement a database cluster. One of the requirements is to share the disks between the nodes of the cluster to access the same LUN. Which of the following protocols Should the company use? (Select TWO)
- A. Nfs
- B. CIFS
- C. Raid 10
- D. Iscsi
- E. FTP
- F. fc
Answer: D,F
Explanation:
Explanation
The correct answer is C and F. iSCSI and FC.
iSCSI and FC are protocols that the company can use to share the disks between the nodes of the cluster to access the same LUN. A LUN, or logical unit number, is a unique identifier for a block of storage space that can be accessed by a host system or a cluster of systems. iSCSI and FC are both block-level protocols that allow transferring data between the storage device and the host system or cluster over a network.
iSCSI stands for Internet Small Computer System Interface, which is a protocol that uses TCP/IP to send SCSI commands over an Ethernet network. iSCSI can provide a low-cost and flexible solution for sharing disks between the nodes of the cluster, as it does not require any special hardware or cables, and can use existing network infrastructure. iSCSI can also support encryption and authentication for security purposes .
FC stands for Fibre Channel, which is a protocol that uses optical fiber cables to send SCSI commands over a dedicated network. FC can provide a high-performance and reliable solution for sharing disks between the nodes of the cluster, as it offers high bandwidth, low latency, and error correction. FC can also support zoning and masking for security purposes .
CIFS, or Common Internet File System, is a file-level protocol that allows sharing files and folders over a network. CIFS does not support sharing disks or accessing LUNs at the block level.
FTP, or File Transfer Protocol, is a protocol that allows transferring files between two systems over a network.
FTP does not support sharing disks or accessing LUNs at the block level.
NFS, or Network File System, is a file-level protocol that allows sharing files and folders over a network. NFS does not support sharing disks or accessing LUNs at the block level.
RAID 10, or Redundant Array of Independent Disks 10, is a storage configuration that combines mirroring and striping to provide high performance and fault tolerance. RAID 10 is not a protocol that allows sharing disks or accessing LUNs over a network.
NEW QUESTION # 173
A systems administrator is planning a penetration test for company resources that are hosted in a public cloud.
Which of the following must the systems administrator do FIRST?
- A. Consult the law for the country where the cloud services provider is located
- B. Consult the law for the country where the company's headquarters is located
- C. Consult the cloud services provider's policies and guidelines
- D. Consult the regulatory requirements for the company's industry
Answer: C
Explanation:
Explanation
The first thing that the systems administrator must do before planning a penetration test for company resources that are hosted in a public cloud is to consult the cloud services provider's policies and guidelines. Penetration testing is a type of security assessment that involves simulating an attack on a system or network to identify vulnerabilities and weaknesses. However, not all cloud services providers allow penetration testing on their platforms, or they may have specific rules and requirements for conducting such tests. The systems administrator should check the cloud services provider's policies and guidelines and obtain their permission and approval before performing any penetration testing. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 2.0 Security, Objective 2.4 Given a scenario, implement security automation and orchestration in a cloud environment.

NEW QUESTION # 175
A systems administrator has verified that a physical switchport that is connected to a virtualization host is using all available bandwidth. Which of the following would best address this issue?
- A. Microsegmentation
- B. Port mirroring
- C. Spanning tree
- D. Link aggregation
Answer: D
Explanation:
Link aggregation is a technique that combines multiple physical links into a logical link that provides higher bandwidth and redundancy. Link aggregation can help address the issue of a physical switchport that is connected to a virtualization host using all available bandwidth by increasing the capacity and availability of the connection. Link aggregation can also balance the traffic load across the links and improve the fault tolerance of the network. Link aggregation can be implemented using protocols such as LACP (Link Aggregation Control Protocol) or static configuration. Reference: CompTIA Cloud+ CV0-003 Certification Study Guide, Chapter 3, Objective 3.2: Given a scenario, troubleshoot network connectivity issues.
NEW QUESTION # 176
A cloud engineer has deployed a virtual storage appliance into a public cloud environment. The storage appliance has a NAT to a public IP address. An administrator later notices there are some strange files on the storage appliance and a large spike in network traffic on the machine. Which of the following is the MOST likely cause?
- A. Data encryption is enabled, and the files are hashed.
- B. The storage appliance has no firewall.
- C. The appliance's certificate has expired.
- D. The default password is still configured on the appliance.
Answer: D
Explanation:
One possible cause for the strange files and the large spike in network traffic on the storage appliance is that the default password is still configured on the appliance. A default password is a password that is set by the manufacturer or vendor of a device or software, and it is often easy to guess or find online. If the cloud engineer did not change the default password after deploying the virtual storage appliance, it could allow unauthorized users to access the appliance remotely and upload or download files, which could explain the symptoms observed by the administrator. This is a serious security risk that could compromise the confidentiality, integrity, and availability of the data stored on the appliance.
