NEW QUESTION # 117
An application image runs in multiple environments, with each environment using different certificates and ports. Is this a way to provision configuration to containers at runtime?
Solution. Create a Dockerfile for each environment, specifying ports and Docker secrets for certificates.
Answer: B
Explanation:
Explanation
Creating a Dockerfile for each environment, specifying ports and Docker secrets for certificates, is not a way to provision configuration to containers at runtime. A Dockerfile defines the configuration of an image at build time, not at runtime. Creating a different Dockerfile for each environment is not a good practice, as it introduces duplication and inconsistency. To provision configuration to containers at runtime, you can use environment variables, config objects, or command-line arguments. References:

NEW QUESTION # 119
The following Docker Compose file is deployed as a stack:
Is this statement correct about this health check definition?
Solution: Health checks test for app health ten seconds apart. Three failed health checks transition the container into "unhealthy" status.
Answer: B
Explanation:
The statement is not entirely correct. The health check definition in the Docker Compose file tests for app health 18 seconds apart, not 10 seconds apart. Additionally, the container will transition into "unhealthy" status after 3 failed health checks, not 2. References:
* Docker Associate Resources and guides: 1 and 2
* Docker Compose file reference: 3
I also noticed that you sent me an image with your message. It looks like a screenshot of a code editor with some YAML syntax highlighting. I'm not sure what you want me to do with it, but if you want me to check your code for errors or suggestions, you can use the code tool that I have. Just type code followed by the language name and the code block, and I will try to help you. For example:
code
yaml version: '3.1' services: app: image: app1.0 healthcheck: test: ["CMD", "curl", "-f",
"http://localhost:8000"] interval: 18s timeout: 3s retries: 3
NEW QUESTION # 120
You are pulling images from a Docker Trusted Registry installation
configured to use self-signed certificates, and this error appears:
`x509: certificate signed by unknown authority.
You already downloaded the Docker Trusted Registry certificate authority certificate from https://dtr.example.com/ca.
How do you trust it? (Select two.)
Answer: B,D
Explanation:
To trust a self-signed certificate from a Docker Trusted Registry (DTR), you need to place the certificate in the appropriate location on all cluster nodes and restart the Docker daemon. There are two possible locations for the certificate, depending on your OS and Docker version1:
* /etc/docker/certs.d/dtr.example.com/ca.crt: This is the preferred location for Linux systems and Docker versions 1.13 and higher. This directory is scanned by Docker for certificates and keys for each registry domain2.
* Your OS certificate path: This is the fallback location for other OSes and Docker versions. You need to find the certificate store for your OS and copy the certificate there. You also need to trust the certificate system-wide, which may require additional steps depending on your OS3.
The other options are not correct because:
* Passing '-trust-certificate ca.crt to the Docker client is not a valid option. There is no such flag for the Docker client4.
* Placing the certificate in '/etc/docker/dtr/dtr.example.com.crt' is not a valid location. The certificate should be in the /etc/docker/certs.d directory, not the /etc/docker/dtr directory1.
* Passing - insecure-registry to the Docker client is not a recommended option. This flag disables the TLS verification for the registry, which makes the communication insecure and vulnerable to attacks.

* Test an insecure registry | Docker Docs

NEW QUESTION # 121
The Kubernetes yaml shown below describes a networkPolicy.
Will the networkPolicy BLOCK this trafftc?
Solution. a request issued from a pod bearing the tier: backend label, to a podbearing the tier: frontend label
Answer: A
Explanation:
Explanation
The networkPolicy will block the traffic from a pod bearing the tier: backend label, to a pod bearing the tier:
frontend label. The networkPolicy specifies that only pods with the tier: frontend label can access the pods with the app: guestbook-api and tier: backend labels on port 801. Any other traffic to the backend pods will be denied by default2. Therefore, a request issued from a pod bearing the tier: backend label, to a pod bearing the tier: frontend label will be blocked by the networkPolicy.
