• Question 459:

  A systems administrator receives a ticket stating the following:

  “The programming team received an error during the process deploying applications to the container platform. The error after the containerized applications were created”

  Which the following should the administrator Check FIRST?

  A. The containers

  B. The application

  C. The Scripts

  D. The templates

  Correct Answer: A

  The correct answer is A. The containers.

  The error that the programming team received indicates that the problem occurred after the containerized applications were created, but before they were deployed to the container platform. This suggests that the issue is related to the

  containers themselves, not the application, the scripts, or the templates.

  The containers are the units of software that package up the application code and all its dependencies, such as libraries, frameworks, and configuration files. The containers run on a container platform, such as Docker or Kubernetes, that

  provides the runtime environment and orchestration for the containers. The containers are created from images, which are templates that define how to build and run a container.

  The administrator should check the containers first to see if they are configured correctly, if they have any errors or warnings, if they have the necessary resources and permissions, and if they can communicate with each other and with the

  container platform. The administrator can use tools such as docker ps, docker logs, docker inspect, and docker exec to examine and troubleshoot the containers.

• Question 460:

  CORRECT TEXT

  The QA team is testing a newly implemented clinical trial management (CTM) SaaS application that uses a business intelligence application for reporting. The UAT users were instructed to use HTTP and HTTPS.

  Refer to the application dataflow:

  1A -The end user accesses the application through a web browser to enter and view clinical data.

  2A -The CTM application server reads/writes data to/from the database server.

  1B -The end user accesses the application through a web browser to run reports on clinical data.

  2B -The CTM application server makes a SOAP call on a non-privileged port to the BI application server.

  3B -The BI application server gets the data from the database server and presents it to the CTM application server.

  When UAT users try to access the application using https://ctm.app.com or http://ctm.app.com, they get a message stating: "Browser cannot display the webpage." The QA team has raised a ticket to troubleshoot the issue.
