A.Implement preventative measures
B.Perform a root cause analysis
C.Establish a plan of action
D.Determine scope of the problem

Answer 1

A.Implement preventative measures

Implementing preventative measures comes after verifying full system functionality. It may be possible to preemptively reconfigure other services or network devices to avoid a repeat of the problem.

Question 2

A network administrator is configuring a series of virtual servers. The administrator provisions resources so that additional memory is available daily during a four-hour period. Which solution would best accommodate this provision?

A.Auto-scaling
B.Horizontal scaling
C.Cloud bursting
D.VM templates

Answer 2

A.Auto-scaling

Auto-scaling adjusts the compute capabilities of instances dynamically to match the current workload.

Question 3

A server technician has been diligently troubleshooting a critical service that crashed. They isolated the issue and implemented a possible resolution. What next step should the technician perform?

A.Implement preventative measures
B.Perform a root cause analysis
C.Establish a plan of action
D.Verify full system functionality

Answer 3

D.Verify full system functionality

Once the potential solution has been implemented, the next phase is to test for functionality. Your goal is to ensure that the service or web application has returned to the established service levels.

Question 4

What process controls the access to resources on a cloud platform?

A.Provisioning
B.Identity management
C.Subscription
D.Containerization

Answer 4

B.Identity management

Identity management is the process by which identities are established, and access to resources is controlled. Users are assigned an account and are assigned rights and restrictions enforced by access control systems such as permissions.

Question 5

When following troubleshooting methodology, which step takes place after establishing an action plan but before verifying that function has returned to the system?

A.Implement preventative measures
B.Test the theory
C.Perform a root cause analysis
D.Implement the solution or escalate

Answer 5

D.Implement the solution or escalate

Solution implementation describes following the plan of action. An administrator should make changes and test them, one at a time, to assist with narrowing down the solution.

Question 6

A real estate accounting company would like to migrate its operation to the cloud but has expressed reservations regarding security. A member of the executive suite suggests a collective organization formed in conjunction with several similar companies that have collectively deployed a cloud-based environment. Each member company maintains cloud access. Which of the following is the executive describing?

A.Private
B.Community

A Service Level Agreement (SLA) defines service requirements and expectations between a CSP and its customers

Question 24

A user submitted a support ticket stating that their team is unable to access shared folders. When troubleshooting the issue, which of the following would be examples of identifying the problem rather than its scope? (Select all that apply.)

A.The virtual host lost connection to network storage.
B.Cloud web servers also cannot load data.
C.All users are unable to access file shares.
D.The virtual machine is powered off.

Answer 24

A.The virtual host lost connection to network storage.

D.The virtual machine is powered off.

Understanding that users cannot access shared folders because a virtual host lost connectivity to a network storage is an example of identifying the problem. If the storage hosted files, but is unavailable, then users will not be able to access the share folders.

Understanding that users cannot access shared folders because a virtual machine (VM) is powered off, is an example of identifying the problem. No VM to run file services, no access to shared folders.

Question 25

A cloud technician receives a complaint that one employee cannot access certain cloud resources. The scope of the problem is limited to this particular user. Which of the following troubleshooting steps should the technician try next?

Which solution would be most appropriate for the company to adopt?

A.Acquire new servers
B.Upgrade SaaS package
C.Employ a FaaS solution
D.Utilize ML to manage the storage

Answer 27

C.Employ a FaaS solution

Function as a Service (FaaS) allows the company to offload the responsibility for server management to a cloud service provider

Question 28

A software development company seeks recommendations for streamlining its internal learning management system. The organization requires a solution that eliminates the management overhead of local and cloud server infrastructure, while only paying for compute resources directly associated with the LMS. Which solution would be most appropriate for the company to adopt?

A.Contract with an LMS vendor
B.Upgrade IaaS package
C.Employ a FaaS solution
D.Utilize ML to manage the content storage

Answer 28

C.Employ a FaaS solution

Function as a Service (FaaS) allows the company to offload the responsibility for compute resources to a cloud service provider. FaaS is an event-driven execution model where the cloud provider is responsible for the servers, and the company only pays for the compute time used during function execution. This aligns with the goal of reducing the number of physical servers while still enabling mass data storage.

Question 29

A cloud administrator is troubleshooting a virtual server that has lost its connection to the network. Having updated the drivers and checked for software conflicts without resolving the error, the administrator proceeds to conduct a direct diagnostic test on the virtual NIC by using network diagnostic tools and monitoring the virtual infrastructure’s performance metrics. The diagnostics conclusively show a failure in the physical network adapter that supports the virtual NIC, as indicated by consistent packet loss and physical port errors that are not present when testing other virtual servers connected to the same physical network infrastructure. What is the next step according to the CompTIA troubleshooting methodology?

A.Test the theory
B.Establish a plan
C.Identify the problem
D.Establish a theory of probable cause

Answer 29

B.Establish a plan

The plan of action defines the steps to take, and the administrator should determine these steps ahead of time, as opposed to formulating them during the solution implementation.
