• Question 92:

  A cloud engineer wants to implement a disaster recovery strategy that:

  1. Is cost-effective.

  2. Reduces the amount of data loss in case of a disaster.

  3. Enables recovery with the least amount of downtime.

  Which of the following disaster recovery strategies best describes what the cloud engineer wants to achieve?

  A. Cold site
  B. Off site
  C. Warm site
  D. Hot site
  D. Hot site

  ---

  Explanation

  A hot site is a disaster recovery strategy that is cost-effective, minimizes data loss, and allows for the fastest recovery time in case of a disaster. It is an exact replica of the original site of the organization, with full computer systems as well as near-complete backups of user data. Hot sites are operational 24/7 and can take over functionality from the primary site immediately or with minimal delay.

• Question 93:

  A company recently migrated to a public cloud provider. The company's computer incident response team needs to configure native cloud services tor detailed logging.

  Which of the following should the team implement on each cloud service to support root cause analysis of past events? {Select two).

  A. Log retention
  B. Tracing
  C. Log aggregation
  D. Log rotation
  E. Hashing
  F. Encryption
  A. Log retention
  C. Log aggregation

  ---

  Explanation

  For detailed logging to support root cause analysis of past events, the team should implement log retention to ensure logs are kept for the necessary amount of time and log aggregation to compile logs from various sources for easier analysis and correlation.

  References: Log management practices, including retention and aggregation, are part of the cloud management strategies covered in the CompTIA Cloud+ curriculum, particularly in the domain of technical operations.

• Question 94:

  Which of the following Al/ML technologies consumes text input to discern tone?

  A. Text recognition
  B. Computer vision
  C. Visual recognition
  D. Sentiment analysis
  D. Sentiment analysis

  ---

  Explanation

  Sentiment analysis is an AI/ML technology that processes text to determine the tone. It helps in understanding the sentiments behind the words by analyzing the text input, which can be positive, negative, or neutral.

• Question 95:

  A developer is deploying a new version of a containerized application. The DevOps team wants:

  1. No disruption 2. No performance degradation 3. Cost-effective deployment 4. Minimal deployment time Which of the following is the best deployment strategy given the requirements?

  A. Canary
  B. In-place
  C. Blue-green
  D. Rolling
  C. Blue-green

  ---

  Explanation

  The blue-green deployment strategy is the best given the requirements for no disruption, no performance degradation, cost-effective deployment, and minimal deployment time. It involves maintaining two identical production environments (blue and green), where one hosts the current application version and the other is used to deploy the new version. Once testing on the green environment is complete, traffic is switched from blue to green, ensuring a seamless transition with no downtime.

  References: Understanding various cloud deployment strategies, such as blue-green deployments, is essential for managing cloud environments effectively, as highlighted in the CompTIA Cloud+ objectives, to ensure smooth and efficient application updates.

• Question 96:

  A cloud engineer is troubleshooting RSA key-based authentication from a local computer to a cloud-based server, which is running SSH service on a default port. The following file permissions are set on the authorized keys file:

  -rw-rw-rw-1 ubuntu ubuntu 391 Mar S 01:36 authorized _ keys

  Which of the following security practices are the required actions the engineer Should take to gain access to the server? (Select TWO).

  A. Fix the file permissions with execute permissions to the owner of the file.
  B. Open port 21 access for the computer's public IP address.
  C. Fix the file permissions with read-only access to the owner Of the file.
  D. Open port 22 access for the computer's public IP address.
  E. Open port 21 access for 0.0.0.0/0 CIDR.
  F. open port 22 access for 0.0.0.0/0 CIDR.
  A. Fix the file permissions with execute permissions to the owner of the file.
  D. Open port 22 access for the computer's public IP address.

• Question 97:

  A SaaS provider introduced new software functionality for customers as part of quarterly production enhancements. After an update is implemented, users cannot locate certain transactions from an inbound integration. During the investigation, the application owner finds the following error in the logs:

  Error: REST API - Deprecated call is no longer supported in this release.

  Which of the following is the best action for the application owner to take to resolve the issue?

  A. Update the custom integration to use a supported function.
  B. Include the custom integration in the quarterly testing scope.
  C. Ask the users to monitor the quarterly updates.
  D. Revert the application to the last stable quarterly release.
  A. Update the custom integration to use a supported function.

  ---

  Explanation

  The error message indicates that the SaaS provider has deprecated a function that was previously called by the custom integration. The best action for the application owner to take is to update the custom integration to use a function that is supported in the current release. This is a direct solution to the problem and ensures the custom integration conforms to the updated SaaS provider's API. References: Based on the error message provided and standard practices for dealing with deprecated API calls in a SaaS environment.

• Question 98:

  Which of the following is used to deliver code quickly and efficiently across the development, test, and production environments?

  A. Snapshot
  B. Container image
  C. Serverless function
  D. VM template
  B. Container image

  ---

  Explanation

  A container image is used to deliver code quickly and efficiently across the development, test, and production environments. Container images are lightweight, standalone, executable software packages that include everything needed to run a piece of software, including the code, runtime, system tools, libraries, and settings.

• Question 99:

  A cloud engineer is exploring options to reduce the management overhead of the servers and network. Which of the following cloud service models should the engineer implement?

  A. SaaS
  B. XaaS
  C. PaaS
  D. laaS
  C. PaaS

  ---

  Explanation

  Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.

  Adopting PaaS can significantly reduce the management overhead of servers and networks.

• Question 100:

  A junior cloud administrator was recently promoted to cloud administrator and has been added to the cloud administrator group. The cloud administrator group is the only one that can access the engineering VM. The new administrator unsuccessfully attempts to access the engineering VM. However, the other administrators can access it without issue. Which of the following is the best way to identify the root cause?

  A. Rebooting the engineering VM
  B. Reviewing the administrator's permissions to access the engineering VM
  C. Allowing connections from 0.0.0.070 to the engineering VM
  D. Performing a packet capture on the engineering VM
  B. Reviewing the administrator's permissions to access the engineering VM

  ---

  Explanation

  The best way to identify the root cause of why the new cloud administrator cannot access the engineering VM is by reviewing the administrator's permissions. It is possible that, despite being added to the cloud administrator group, the specific permissions to access the engineering VM were not properly configured.References:

  Permission issues are a common problem in cloud environments, andtroubleshooting such issues is part of the cloud management skills discussed in the CompTIA Cloud+ certification
