GIT PUSH

To start a CI/CD pipeline and run automated tests after modifying the code in a cloned repository, the appropriate command is git push. When a developer pushes the changes to the remote repository, it triggers the CI/CD pipeline configured in the repository. Here are the steps:

Clone the repository from GitLab.

Make the necessary code modifications.

Use git commit to commit the changes locally.

Use git push to push the committed changes to the remote repository.

Pushing the changes to the remote repository initiates the CI/CD pipeline, which typically includes steps like building the application, running tests, and deploying the application if tests pass.

When configuring a Cisco IOS XE networking device using RESTCONF, the default data encoding method is application/yang-data+json. This MIME type indicates that the data is encoded in JSON format and structured according to YANG data models. YANG (Yet Another Next Generation) is a data modeling language used to model configuration and state data manipulated by the NETCONF protocol, which RESTCONF leverages.

In the given Dockerfile, the WORKDIR /app command sets the working directory for any subsequent commands to /app. This means that any commands following this line will be executed within the /app directory inside the Docker container. The COPY . . command copies the contents of the current directory on the host machine to the /app directory in the container. Finally, the CMD ["node", "source/server.js"] command specifies the command to run when the container starts, which in this case is node source/server.js.

An HTTP 502 Bad Gateway error indicates that the server acting as a gateway or proxy received an invalid response from the upstream server. This suggests there may be an issue with the configuration or availability of the server behind the load balancer.

HTTP 502 Error: This error occurs when the load balancer or gateway receives an invalid response from the backend server.

Server Configuration: The issue is likely due to misconfiguration or problems with the backend server that needs to be resolved.

Option A is correct as it identifies that the issue lies with the server configuration behind the load balancer.

DNS (Domain Name System) is the technology responsible for resolving a host name to an IP address. It translates domain names, which are easier for humans to remember, into IP addresses that are used by network devices to locate and communicate with each other over the internet. When a user types a domain name into a web browser, the DNS server maps it to the corresponding IP address so the browser can load the desired web page.
