PAS-C01 Operations and Maintenance Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  Launch EC2 instances, then create a target group, then register instances with target group, then create an ALB with HTTPS listener and SSL certificate, then update DNS.

  Why this is correct

  This is the correct order because you must first have the EC2 instances running, then create the target group to register them, then create the ALB with the listener and certificate, and finally update DNS to point to the ALB.

• ✗

  Launch EC2 instances, then create an ALB with HTTPS listener and SSL certificate, then create a target group, then register instances, then update DNS.

  Why it's wrong here

  This is incorrect because you cannot create an ALB without a target group; the target group must exist and be specified during ALB creation.

• ✗

  Create a target group, then register instances, then create an ALB with HTTPS listener and SSL certificate, then launch EC2 instances, then update DNS.

  Why it's wrong here

  This is incorrect because you cannot register instances that don't exist yet; EC2 instances must be launched before they can be registered to a target group.

• ✗

  Update DNS, then launch EC2 instances, then create a target group, then register instances, then create an ALB with HTTPS listener and SSL certificate.

  Why it's wrong here

  This is incorrect because DNS must point to an existing ALB; updating DNS before the ALB is created will cause a resolution failure.
