An organization is migrating all its Mule applications to Runtime Fabric (RTF). None of the Mule applications use Mule domain projects.

Currently, all the Mule applications have been manually deployed to a server group among several customer hosted Mule runtimes.

Port conflicts between these Mule application deployments are currently managed by the DevOps team who carefully manage Mule application properties files.

When the Mule applications are migrated from the current customer-hosted server group to Runtime Fabric (RTF), fo the Mule applications need to be rewritten and what DevOps port configuration responsibilities change or stay the same?

  1. Yes, the Mule applications Must be rewritten
    DevOps No Longer needs to manage port conflicts between the Mule applications
  2. Yes, the Mule applications Must be rewritten
    DevOps Must Still Manage port conflicts.
  3. NO, The Mule applications do NOT need to be rewritten
    DevOps MUST STILL manage port conflicts
  4. NO, the Mule applications do NO need to be rewritten
    DevOps NO LONGER needs to manage port conflicts between the Mule applications.

Answer(s): C

Explanation:

* Anypoint Runtime Fabric is a container service that automates the deployment and orchestration of your Mule applications and gateways.

* Runtime Fabric runs on customer-managed infrastructure on AWS, Azure, virtual machines (VMs) or bare-metal servers.

* As none of the Mule applications use Mule domain projects. applications are not required to be rewritten. Also when applications are deployed on RTF, by default ingress is allowed only on 8081.

* Hence port conflicts are not required to be managed by DevOps team



An organization is evaluating using the CloudHub shared Load Balancer (SLB) vs creating a CloudHub dedicated load balancer (DLB). They are evaluating how this choice affects the various types of certificates used by CloudHub deplpoyed Mule applications, including MuleSoft-provided, customer
provided, or Mule application-provided certificates.

What type of restrictions exist on the types of certificates that can be exposed by the CloudHub Shared Load Balancer (SLB) to external web clients over the public internet?

  1. Only MuleSoft-provided certificates are exposed.
  2. Only customer-provided wildcard certificates are exposed.
  3. Only customer-provided self-signed certificates are exposed.
  4. Only underlying Mule application certificates are exposed (pass-through)
