NEW QUESTION # 32
Will this command mount the host's '/data1directory to the ubuntu container in read-only mode?
Solution. 'docker run -v /data:/mydata -mode readonly ubuntu'
Answer: B
Explanation:
The command docker run -v /data:/mydata -mode readonly ubuntu will not mount the host's /data1 directory to the ubuntu container in read-only mode. The commandhas several errors that prevent it from working correctly. First, the host directory should be /data1 instead of /data, as specified in the question. Second, the option flag should be --mode instead of -mode, and it should be placed before the image name. Third, the mode value should be ro instead of readonly, as per the Docker documentation1. The correct command should be docker run -v /data1:/mydata --mode ro ubuntu, which will mount the host's /data1 directory as a read-only volume at /mydata inside the container1. Reference:
docker run | Docker Docs
NEW QUESTION # 33
Will a DTR security scan detect this?
Solution. image configuration poor practices, such as exposed ports or inclusion of compilers in production images
Answer: B
Explanation:
Explanation
A DTR security scan does not detect image configuration poor practices, such as exposed ports or inclusion of compilers in production images. A DTR security scan is a feature that scans images for known vulnerabilities in the software packages or dependencies that are installed in the image. A DTR security scan does not check for image configuration poor practices, such as exposing unnecessary ports or including unnecessary tools in production images. To avoid image configuration poor practices, you should follow the Dockerfile best practices and use multi-stage builds to optimize your images. References:

NEW QUESTION # 34
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 <container-id>
Answer: B
Explanation:
= The command docker logs <container-id> will not configure a Docker container to export container logs to the logging solution, such as Splunk. This command only displays the logs of a specific container in the standard output or a file, but does not send them to any external system1. To export container logs to Splunk, you need to use the Docker Logger Drivers, which are plugins that provide logging capabilities for Docker containers2. The Splunk logging driver sends container logs to HTTP Event Collector in Splunk Enterprise and Splunk Cloud3. To use the Splunk logging driver for a specific container, you need to use the command-line flags --log-driver and --log-opt with docker run, and provide the Splunk token and URL as options3. For example:
$ docker run --log-driver=splunk --log-opt splunk-token=VALUE --log-opt splunk-url=VALUE ...

NEW QUESTION # 35
Will this action upgrade Docker Engine CE to Docker Engine EE?
Solution.Disable the Docker service via 'chkconfig' or 'systemctl'.
Answer: B
Explanation:
The action will not upgrade Docker Engine CE to Docker Engine EE. Disabling the Docker service via chkconfig or systemctl will only stop the Docker daemon from running, but it will not change the version or edition of the Docker engine1. To upgrade Docker Engine CE to Docker Engine EE, you need to follow these steps2:
Download your Docker Enterprise license from the Docker Store).
Install the docker-ee package from the Docker repository.
Restart the Docker service and verify the version and edition. Reference: Start or stop the Docker daemon), How to upgrade Docker 18.09 Community Edition to Docker Enterprise 18.09)
NEW QUESTION # 36
Does this command create a swarm service that only listens on port 53 using the UDP protocol?
Solution. 'docker service create -name dns-cache -p 53:53/udp dns-cache"
Answer: B
Explanation:
Explanation
= The command 'docker service create -name dns-cache -p 53:53/udp dns-cache' is not correct and will not create a swarm service that only listens on port 53 using the UDP protocol. There are two errors in the command:
* The option -name should be --name with two dashes, otherwise it will be interpreted as a short option -n followed by an argument ame1.
* The option -p or --publish will publish the service port to the host port, which means the service will be reachable from outside the swarm2. To create a service that only listens on the internal network, you need to use the --publish-add option with the mode=ingress flag3.
The correct command should be:
docker service create --name dns-cache --publish-add mode=ingress,target=53,published=53,protocol=udp dns-cache References:

* Publish ports on the host | Docker Docs
* Publish a port for a service | Docker Docs
