CompTIA Cloud+ Certification Exam Sample Questions (Q286-Q291):

NEW QUESTION # 286
A software development manager is looking for a solution that will allow a team of developers to work in isolated environments that can be spun up and torn down quickly.
Which of the following is the MOST appropriate solution?

A. Containers
B. Ballooning
C. Software-defined storage
D. File subscriptions

Answer: A

NEW QUESTION # 287
A cloud administrator is investigating slow VM performance. The administrator has checked the physical server performance and has identified the host is under stress due to a peak usage workload. Which of the following is the NEXT step the administrator should complete?

A. Migrate the VM to a different host.
B. Perform a system restart.
C. Perform a root cause analysis
D. Document the findings.

Answer: A

Explanation:
Migrating the VM to a different host is a common technique to improve the performance of a VM that is suffering from resource contention or contention on the physical server. By moving the VM to a different host, the administrator can:
Reduce the stress and load on the original host, which may be under stress due to a peak usage workload.
Increase the availability and reliability of the VM, which may be experiencing slow performance due to resource contention or contention on the original host.
Balance the workload and resource utilization across multiple hosts, which may improve the overall performance and efficiency of the cloud environment.
Migrating the VM to a different host can be done manually or automatically, depending on the configuration and capabilities of the cloud platform. Some cloud platforms support live migration, which allows moving a VM to a different host without interrupting its operation or service. Other cloud platforms require shutting down or pausing the VM before migrating it to a different host .

NEW QUESTION # 288
A cloud administrator works for an online gaming company that is hosting its multiplayer servers in a public IaaS cloud. The following metrics are reported during a controlled beta test:
RAM usage 80%
Bandwidth usage 50%
Average ping 800ms
The beta test shows poor performance for gamers. Which of the following should the cloud administrator implement FIRST to improve the gamers' experience?

A. Increase network bandwidth on the multiplayer servers.
B. Deploy multiplayer servers in public cloud locations closer to the user base.
C. Increase the RAM on the multiplayer servers.
D. Scale the deployment of multiplayer servers by doubling the number of VMs.

Answer: A

NEW QUESTION # 289
A company is utilizing a private cloud solution that is hosted within its datacenter. The company wants to launch a new business application, which requires the resources below:

The current private cloud has 30 vCPUs and 512GB RAM available. The company is looking for a quick solution to launch this application, with expected maximum sessions to be close to 24,000 at launch and an average of approximately 5,000 sessions.
Which of the following solutions would help the company accommodate the new workload in the SHORTEST amount of time and with the maximum financial benefits?

A. Add more capacity to the private cloud
B. Set up cloud bursting for the additional resources
C. Configure auto-scaling within the private cloud
D. Migrate all workloads to a public cloud provider

Answer: B

Explanation:
Cloud Bursting can be used for both compute and storage. This question is about compute capability.
"Compute Bursting" unleashes the high-performance compute capabilities of the cloud for processing locally created datasets. (reference: https://www.ctera.com/it-initiatives/cloud-bursting/)
https://azure.microsoft.com/en-us/overview/what-is-cloud-bursting/

NEW QUESTION # 290
A cloud administrator updates the syslog forwarder configuration on a local server in production to use a different port. The development team is no longer receiving the audit logs from that server. However, the security team can retrieve and search the logs for the same server. Which of the following is MOST likely the issue?

A. The development team is not looking at the correct server when querying for the logs.
B. The development team's syslog server is configured to listen on the wrong port.
C. The audit logging service has been disabled on the server.
D. The security team has greater permissions than the development team.

Answer: D
