Question 20

A DevOps engineer must build a Docker image to containerize an application. Then the image must be pushed to a repository on Docker Hub in a CI/CD pipeline using GitHub Actions.

Which approach securely encrypts the Docker Hub access token as an environment variable within the CI/CD pipeline?

Options:

Store the access token with GitHub environment variables

Store the access token with GitHub encrypted secrets

Store the access token in an environment file in the repository

Hard code the access token in the repository with Base64 encoding

Question 21

How long analysis systems such as Elasticsearch, Logstash, and Kibana Stack handle ingesting unstructured logs from different devices in various formats?

Options:

All devices that generate syslogs must use agents that process the local logs and transmit them in a specific format to the ELK Stack.

All logs are stored in their unstructured text format, and the ELK Stack performs data analysis by intelligently parsing the logs using machine learning algorithms.

All different message formats are parsed separately using custom filters, and the resulting structured data is stored for later analysis.

A single, comprehensive log format is defined on the ELK Stack. All incoming logs, regardless of format, are transformed to match the comprehensive format, and only applicable fields are populated.

Question 22

Which method is a safe way to provide a username/password combination to an application running as a service in a Docker container?

Options:

encode the value with base64 in a secure DNS CTEXT entry

as an environment variable in the Dockerfile

Docker environment variable

Docker secrets

Question 23

Refer to the exhibit.

A development team is designing an application that will include multiple components and services. To streamline the process, CO/CD must be implemented.
