IaaS is suitable for deploying virtual machines, as it allows the customers to choose their preferred OS, applications, settings, etc., and customize them according to their needs.

• Question 32:

  A cloud administrator needs to reduce the cost of cloud services by using the company's off-peak period. Which of the following would be the BEST way to achieve this with minimal effort?

  A. Create a separate subscription.

  B. Create tags.

  C. Create an auto-shutdown group.

  D. Create an auto-scaling group.

  Correct Answer: C

  Creating an auto-shutdown group is the best way to reduce the cost of cloud services by using the company's off-peak period with minimal effort. An auto-shutdown group is a feature that allows customers to automatically turn off or shut down certain cloud resources or services during a specified time period or schedule. An auto-shutdown group can help to reduce the cost of cloud services by minimizing the consumption of resources or services during off-peak periods, when they are not needed or used. An auto-shutdown group can also help to reduce the effort of managing cloud resources or services by automating the shutdown process, without requiring any manual intervention or configuration.

• Question 33:

  A systems administrator is deploying a new virtualized environment. The setup is a three- server cluster with 12 VMs running on each server. While executing a vertical-scaling test of the vCPU on the VMs, the administrator gets an error. Which of the following issues is MOST likely occurring?

  A. Compute

  B. Storage

  C. Licensing

  D. Scripts

  Correct Answer: A

  If a systems administrator gets an error while executing a vertical-scaling test of the vCPU on VMs in a virtualized environment, the issue is MOST likely related to "Compute" (A).

  In a virtualized environment, the "Compute" refers to the processing power (CPU and RAM) of the physical host machine that runs multiple virtual machines. Vertical scaling is the process of adding more resources to a virtual machine to increase its processing power. If the administrator is encountering an error while executing a vertical-scaling test of the vCPU on VMs, it indicates that there may be an issue with the compute resources available to the VMs, such as insufficient processing power or limited capacity on the physical host.

• Question 34:

  A company would like to migrate its current on-premises workloads to the public cloud. The current platform requires at least 80 instances running at all times to work properly. The company wants the workload to be highly available, even if

  the cloud provider loses one region due to a catastrophe, and the costs to be kept to a minimum. Which of the following strategies should the company implement?

  A. Create /25 subnets in two regions and run 80 instances on each one.

  B. Create /26 subnets in two regions and run 40 instances on each one.

  C. Create /26 subnets in three regions and run 40 instances on each one

  D. Create /26 subnets in three regions and run 80 instances on each one.

  Correct Answer: C

  1.at least 80 instances running at all times to work 2.wants the workload to be highly available, even if the cloud provider loses one region due to a catastrophe 3.costs to be kept to a minimum

  The choice of /26 subnets allows for up to 64 IP addresses, which is sufficient for running 40 instances in each region - Respect al 3 requiraments

  By running 40 instances in each region, the company can achieve the desired level of availability while keeping costs lower - So, we have cost optimization !

  By distributing the workload across three regions, the company ensures redundancy and fault tolerance. They want AT LEAST 80 instances.

• Question 35:

  A cloud administrator needs to coordinate and automate the management of a company's secrets and keys for all its cloud services with minimal effort and low cost. Which of the following is the BEST option to achieve the goal?

  A. Implement database as a service

  B. Configure Key Vault

  C. Use password as a service

  D. Implement KeePass

  Correct Answer: B

  Key Vault is a service that allows you to store and manage secrets and keys for your cloud services in a secure and centralized way. It also provides access control, auditing, and encryption features. This would be the best option to automate the management of secrets and keys for all cloud services with minimal effort and low cost. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 3.0 Maintenance, Objective 3.4 Given a scenario, implement automation and orchestration to optimize cloud operations.

• Question 36:

  An enterprise recently upgraded the memory of its on-premises VMs from 8GB to 16GB. However, users are not experiencing any performance benefit. Which of the following is the MOST likely reason?

  A. Insufficient memory on the hypervisor

  B. Operating system memory limit

  C. Memory mismatch error

  D. Dynamic memory allocation

  Correct Answer: B

  The most likely reason why users are not experiencing any performance benefit after upgrading the memory of their on-premises VMs is that the operating system has a memory limit that prevents it from using more than 8GB of RAM. This could be due to the operating system version, edition, or configuration. The systems administrator should check the operating system settings and requirements and adjust them accordingly to allow the VMs to use the full 16GB of RAM. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 4.0 Troubleshooting, Objective 4.3 Given a scenario, troubleshoot capacity issues within a cloud environment.

• Question 37:

  A development team recently completed testing changes to a company's web-based CMS in the sandbox environment. The cloud administrator deployed these CMS application changes to the staging environment as part of the next phase in the release life cycle. The deployment was successful, but after deploying the CMS application, the web page displays an error message stating the application is unavailable. After reviewing the application logs, the administrator sees an error message that the CMS is unable to connect to the database. Which of the following is the BEST action for the cloud administrator to perform to resolve the issue?

  A. Modify the deployment script to delete and recreate the database whenever the CMS application is deployed.

  B. Modify the ACL to allow the staging environment to access the database in the sandbox environment.

  C. Modify the CMS application deployment to use the previous version and redeploy the application.

  D. Modify the configuration settings of the CMS application to connect to the database in the current environment.

  Correct Answer: D

  Modifying the configuration settings of the CMS (Content Management System) application to connect to the database in the current environment is what the cloud administrator should do to resolve the issue of web page displaying an error message stating the application is unavailable after deploying CMS application changes to the staging environment. A CMS is a software or platform that allows users to create, manage, and publish web content. A CMS may use a database to store and retrieve web content and information. A staging environment is a testing or pre-production environment that simulates the production environment and allows users to verify and validate changes or updates before deploying them to production. Modifying the configuration settings of the CMS application can help to resolve the issue by ensuring that the CMS application can access and communicate with the database in the current environment, rather than using the previous or default settings that may point to a different or non-existent database.

• Question 38:

  A cloud administrator has created a new asynchronous workflow lo deploy VMs to the cloud in bulk. When the workflow is tested for a single VM, it completes successfully. However, if the workflow is used to create 50 VMs at once, the job fails. Which of the following is the MOST likely cause of the issue? (Choose two.)

  A. Incorrect permissions

  B. Insufficient storage

  C. Billing issues with the cloud provider

  D. No connectivity to the public cloud

  E. Expired API token

  F. Disabled autoscaling

  Correct Answer: BF

  Insufficient storage could cause the deployment of 50 VMs to fail as the cloud may not have enough available storage to create the instances.

  Disabled autoscaling could also cause the deployment to fail as the workflow is set to deploy a large number of VMs at once, and without autoscaling, the cloud may not have the resources to handle the workload.

• Question 39:

  A systems administrator is asked to implement a new three-host cluster. The cloud architect specifies this should be a testing environment, and the budget is limited. The estimated resource consumption for each application is as follows:

  

  A. Three public cloud hosts with four cores 120GB of RAM 100GB of storage 1Gbps

  B. Three public cloud hosts with six cores 80GB of RAM 180GB of storage 150Mbps

  C. Three public cloud hosts with six cores 80GB of RAM 1TB of storage 200Mbps

  D. Four public cloud hosts with four cores 140GB of RAM 200GB of storage

  Correct Answer: B

  The best option to implement a new three-host cluster with a limited budget for testing purposes is to use three public cloud hosts with six cores, 80GB of RAM, 180GB of storage, and 150Mbps of bandwidth each. This option will provide enough resources to run all the applications without exceeding their estimated consumption, while also minimizing the cost and complexity of the cluster. The other options either provide insufficient or excessive resources, which could affect the performance or cost of the cluster. Reference: [CompTIA Cloud+ Certification Exam Objectives], Domain 1.0 Configuration and Deployment, Objective 1.2 Given a scenario involving requirements for deploying an application in the cloud, select an appropriate solution design.

  A. A root cause analysis

  B. Application documentation

  C. Acquired evidence

  D. Application logs

  Correct Answer: A

  A root cause analysis is what will most likely be requested by the Chief Information Officer (CIO) to understand the issue and its resolution after a system compromise that was resolved by the engineering team after 12 hours. A root cause

  analysis is a technique of investigating and identifying the underlying or fundamental cause or reason for an incident or issue that affects or may affect the normal operation or performance of a system or service. A root cause analysis can

  help to understand the issue and its resolution by providing information such as:

  What happened: This describes what occurred during the incident or issue, such as symptoms, effects, impacts, etc.

  Why it happened: This explains why the incident or issue occurred, such as triggers, factors, conditions, etc.

  How it was resolved: This details how the incident or issue was fixed or mitigated, such as actions, steps, methods, etc.

  How it can be prevented: This suggests how the incident or issue can be avoided or reduced in the future, such as recommendations, improvements, changes, etc.
