1. A. Compliance
2. B. laaS v
3. C. SaaS
4. D. Firewall capabilities
5. E. Regulatory
6. F. Implementation timeline
7. G. Service availability

Correct Answer: AD
For a government agency considering cloud migration, compliance and regulatory considerations are of utmost importance. The agency must ensure that the migration aligns with legal requirements, industry standards, and government regulations specific to the public sector.References: Compliance and regulatory considerations are crucial factors in the cloud migration process for government entities, as emphasized in the CompTIA Cloud+ certification.

A high-usage cloud resource needs to be monitored in real time on specific events to guarantee its availability. Which of the following actions should be used to meet this requirement?

1. A. Configure a ping command to identify when the cloud instance is out of service.
2. B. Create a dashboard with visualizations to filter the status of critical activities.
3. C. Collect all the daily activity from the cloud instance and create a dump file for analysis.
4. D. Schedule an hourly scan of the network to check for the availability of the resource.

Correct Answer: B
To guarantee real-time monitoring of a high-usage cloud resource, creating a dashboard with visualizations to filter the status of critical activities is effective. This allows for a quick visual assessment of the system's health and performance, enabling immediate action if specific events indicate potential issues with availability.References: Real-time monitoring and the use of dashboards for tracking critical cloud resources are part of the cloud management best practices covered under the CompTIA Cloud+ objectives.

A company just learned that the data in its object storage was accessed by an unauthorized party. Which of the following should the company have done to make the data unusable?

1. A. The company should have switched from object storage to file storage.
2. B. The company should have hashed the data.
3. C. The company should have changed the file access permissions.
4. D. The company should have encrypted the data at rest.

Correct Answer: D
Encrypting the data at rest is a crucial security measure to make the data unusable to unauthorized parties. If the object storage data was accessed by an unauthorized party, having the data encrypted would ensure that the data remains confidential and inaccessible without the proper encryption keys, thus mitigating the impact of the breach.

Which of the following would allow a cloud engineer to flatten a deeply nested JSON log to improve readability for analysts?

1. A. Grafana
2. B. Kibana
3. C. Elasticsearch
4. D. Logstash

Correct Answer: D
Logstash can be used to flatten a deeply nested JSON log, which would improve readability for analysts. Logstash is a data processing pipeline that ingests data from various sources, transforms it, and then sends it to a "stash" like Elasticsearch.

A developer is building a new application version using a CI/CD pipeline. The developer receives the following error message log when the build fails:

Which of the following is the most likely cause of this failure?

1. A. Incorrect version
2. B. Test case failure
3. C. Broken build pipeline
4. D. Dependency issue

Correct Answer: D
The error message indicates that the 'requests' module, which is a dependency, is not found. The failure is most likely due to the 'requests' library not being installed or not included in the environment where the application is running.References: Dependency management is a crucial part of maintaining a CI/CD pipeline, a topic included in the CompTIA Cloud+ examination objectives.
