  Which of the following do developers use to keep track of changes made during software development projects?

  A. Code drifting
  B. Code control
  C. Code testing
  D. Code versioning

• Question 112:

  A company's content management system (CMS) service runs on an laaS cluster on a public cloud. The CMS service is frequently targeted by a malicious threat actor using DDoS.

  Which of the following should a cloud engineer monitor to identify attacks?

  A. Network flow logs
  B. Endpoint detection and response logs
  C. Cloud provider event logs
  D. Instance syslog
  A. Network flow logs

  ---

  Explanation

  To identify DDoS attacks against a CMS service, a cloud engineer should monitor network flow logs.

  These logs provide data about the IP traffic going to and from network interfaces in a public cloud, which is essential for detecting the increased traffic volumes typically associated with DDoS attacks.

• Question 113:

  A cloud engineer is responsible for a legacy web application that runs on an on-premises VM environment.

  The VM environment is approaching end of life. The engineer needs to migrate the web application to the cloud as quickly as possible because the VM environment has the following limitations: The VM environment has a single IOGB disk.

  The VM environment still uses 10Mbps, which leaves a 100Mbps WAN connection underutilized.

  No installation media is available.

  Which of the following is the best way to migrate the web application to the cloud?

  A. Use the VM import connector to import the VM into the cloud.
  B. Use import/export to import the VM as a snapshot and attach it to a cloud instance.
  C. Use REST APIs to import an image of the VM into the cloud.
  D. Use object storage to create a backup of the VM and restore data into the cloud instance.
  A. Use the VM import connector to import the VM into the cloud.

  ---

  Explanation

  A VM import connector is a tool that allows you to import virtual machines from your on-premises environment into the cloud using a graphical user interface. This is the fastest and easiest way to migrate a legacy web application without requiring installation media or changing the configuration of the VM. The VM import connector can also handle the disk size and network bandwidth limitations of the on-premises VM

  environment.

• Question 114:

  Which of the following facilitates the continuous deployment of cloud applications without performing a clean install on each iteration?

  A. Debian package
  B. Version management
  C. Container image
  D. Bare-metal server
  C. Container image

  ---

  Explanation

  Container images package applications and their dependencies, enabling continuous deployment by quickly updating containers without full clean installs each time.

• Question 115:

  A bank informs an administrator that changes must be made to backups for long-term reporting purposes.

  Which of the following is the most important change the administrator should make to satisfy these requirements?

  A. Location of the backups
  B. Type of the backups
  C. Retention of the backups
  D. Schedule of the backups
  C. Retention of the backups

  ---

  Explanation

  For long-term reporting purposes, the most critical aspect to consider is the retention period of the backups.

  This is because the bank will likely require access to historical data for audit, compliance, and reporting purposes. The retention policy will need to ensure that backups are kept for the required duration, which may be several years depending on regulatory and business needs. Adjusting the retention policy will help ensure that the necessary data is preserved for as long as it is needed, without unnecessary data accumulation that could lead to higher costs and management complexity.

• Question 116:

  Which of the following application migration strategies will best suit a customer who wants to move a simple web application from an on-premises server to the cloud?

  A. Rehost
  B. Rearchitect
  C. Refactor
  D. Retain
  A. Rehost

  ---

  Explanation

  Rehosting, often referred to as a "lift and shift" strategy, is the best suit for a customer who wants to move a simple web application from an on-premises server to the cloud. It involves moving the application to the cloud without making significant changes, which can be a quick and cost-effective migration approach for straightforward applications.

  References:

  The various cloud migration strategies, including rehosting, are part of the knowledge base for cloud migration in the CompTIA Cloud+ certification.

• Question 117:

  A company that has several branches worldwide needs to facilitate full access to a specific cloud resource to a branch in Spain. Other branches will have only read access.

  Which of the following is the best way to grant access to the branch in Spain?

  A. Set up MFA for the users working at the branch.
  B. Create a network security group with required permissions for users in Spain.
  C. Apply a rule on the WAF to allow only users in Spain access to the resource.
  D. Implement an IPS/IDS to detect unauthorized users.
  B. Create a network security group with required permissions for users in Spain.

  ---

  Explanation

  The best way to grant full access to a specific cloud resource to a branch in Spain, while other branches have only read access, is to create a network security group with the required permissions. This group can be configured to allow full access to users within the branch's IP range while restricting others to read-only access.

• Question 118:

  A cloud vendor notifies an administrator that the router version currently in use will no longer be made.

  Which of the following describes the stage the router has reached and what needs to be done?

  A. The router has reached end of support. The router's software should be updated.
  B. The router has reached end of support. The router should be replaced.
  C. The router has reached end of life. The router's software should be updated.
  D. The router has reached end of life. The router should be replaced.
  D. The router has reached end of life. The router should be replaced.

  ---

  Explanation

  When a product reaches end of life, it is no longer manufactured or supported by the vendor. The proper action is to replace the router with a supported model to ensure continued functionality, compatibility, and security updates.

• Question 119:

  An update is being deployed to a web application, and a systems administrator notices the cloud SQL database has stopped running. The VM is responding to pings, and there were not any configuration changes scheduled for the VM.

  Which of the following should the administrator check NEXT?

  A. Logs on the VM
  B. Firewall on the VM
  C. Memory on the VM
  D. vGPU performance on the VM
  A. Logs on the VM

  ---

  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.

• Question 120:

  A cloud engineer must configure a backup at the end of the month. Given the following requirements: Minimal backup size Faster backup speed.

  Which of the following backup types best meets the requirements?

  A. Tape
  B. Full
  C. Differential
  D. Incremental
  D. Incremental

  ---

  Explanation

  An incremental backup stores only the data that has changed since the most recent backup. This results in the smallest backup size and the fastest backup operation because the least amount of data needs to be copied during each backup cycle.
