NEW QUESTION # 135
Are these conditions sufficient for Kubernetes to dynamically provision a persistentVolume, assuming there are no limitations on the amount and type of available external storage?
Solution: A default storageClass is specified, and subsequently a persistentVolumeClaim is created.

  • A. Yes
  • B. No

Answer: A

Explanation:
Explanation
These conditions are sufficient for Kubernetes to dynamically provision a persistentVolume, because a default storageClass provides the information needed to create a persistentVolume that matches the persistentVolumeClaim. According to the official documentation, if no storageClass is specified or requested, then the default one is used.

NEW QUESTION # 136
The following Docker Compose file is deployed as a stack:

Is this statement correct about this health check definition?
Solution.Health checks lest for app health ten seconds apart. Three failed health checks transition the container into "unhealthy" status.

  • A. Yes
  • B. No

Answer: A

Explanation:
The statement is correct. In the provided Docker Compose file, a health check is defined for the service "app". It uses curl to perform a health check on the application every 10 seconds (as specified by the "interval" parameter). If it fails three times (as specified by the "retries" parameter), then the container is marked as unhealthy. A health check is a way of checking the health of a running container and applying actions based on the result1. It can be used to monitor the status of the service and restart the container if it becomes unhealthy2. Reference:

NEW QUESTION # 139
Your organization has a centralized logging solution, such as Splunk.
Will this configure a Docker container to export container logs to the logging solution?
Solution.docker logs <eontainer-id>

  • A. Yes
  • B. No

Answer: B

Explanation:
Explanation
= The command docker logs <container-id> will not configure a Docker container to export container logs to the logging solution. This command is used to fetch the logs of a container from the Docker daemon, not to send them to an external service1. To export container logs to a logging solution, such as Splunk, you need to use a Docker logging driver2. A logging driver is a way of plugging into the Docker engine to forward logs to a specific destination2. Docker supports several built-in logging drivers, including one for Splunk3. To use the Splunk logging driver, you need to specify the --log-driver splunk option when running a container, and provide some additional options, such as the Splunk HTTP Event Collector token and URL3. Alternatively, you can configure the Splunk logging driver as the default logging driver for the Docker daemon by editing the daemon.json file4. References:
