Explanation:

Deployment automation in MuleSoft is typically achieved via:
1. Mule Maven Plugin (E): Automates build and deploy steps within CI/CD pipelines.
2. Runtime Manager (A): Allows deployment via UI and can be integrated with CI/CD.
3. Anypoint Platform CLI (B): Enables scripting and automation of deployment processes.

These tools are designed to work in DevOps environments, allowing repeatable, testable, and scalable deployment strategies. Anypoint Studio (D) is primarily a development IDE, and API Community Manager (F) is used for engagement, not deployment.

Explanation

Correct Answer: Implement required changes to the Process API implementation so that, whenever possible, the Process API’s RAML definition remains unchanged. Key requirement in the question is:

>> Approach that minimizes the impact of this change on API clients Based on above:

>> Updating the RAML definition would possibly impact the API clients if the changes require any thing mandatory from client side. So, one should try to avoid doing that until really necessary.

>> Implementing the changes as a completely different API and then redirectly the clients with 3xx status code is really upsetting design and heavily impacts the API clients.

>> Organisations and IT cannot simply postpone the changes required until all API consumers acknowledge they are ready to migrate to a new Process API or API version. This is unrealistic and not possible.

The best way to handle the changes always is to implement required changes to the API implementations so that, whenever possible, the API’s RAML definition remains unchanged.

Explanation

Correct Answer: An SLA for the upstream API CANNOT be provided.

*****************************************

>> First thing first, the default HTTP response timeout for HTTP connector is 10000 ms (10 seconds). NOT 500 ms.

>> Mule runtime does NOT apply any such "load-dependent" timeouts. There is no such behavior currently in Mule.

>> As there is default 10000 ms time out for HTTP connector, we CANNOT always guarantee that the invocation of the downstream API will run to completion without timing out due to its unreliable SLA times. If the response time crosses 10 seconds then the request may time out.

The main impact due to this is that a proper SLA for the upstream API CANNOT be provided.

Explanation

Correct Answer: JSON threat protection

*****************************************

Fact: Technically, there are no restrictions on what policy can be applied in what layer. Any policy can be applied on any layer API. However, context should also be considered properly before blindly applying the policies on APIs.

That is why, this question asked for a policy that would LEAST likely be applied to a Process API.

From the given options:

>> All policies except "JSON threat protection" can be applied without hesitation to the APIs in Process tier.

>> JSON threat protection policy ideally fits for experience APIs to prevent suspicious JSON payload coming from external API clients. This covers more of a security aspect by trying to avoid possibly malicious and harmful JSON payloads from external clients calling experience APIs.

As external API clients are NEVER allowed to call Process APIs directly and also these kind of malicious and harmful JSON payloads are always stopped at experience API layer only using this policy, it is LEAST LIKELY that this same policy is again applied on Process Layer API.

Explanation:

To make CloudHub apps available at a custom domain (api.acmecorp.com):
TLS Certificate: Must be issued for the exact domain (api.acmecorp.com).
DNS Record: A CNAME must point the domain to the DLB’s Anypoint DNS hostname (acme-dlb-prod.lb.anypointdns.net).

Why not other options?

(A): Uses an A record, but DLBs rely on CNAME for scalability.
(C): Incorrect—TLS must cover the custom domain, not the DLB hostname.
(D): Points to cloudhub.io, which is wrong for DLBs.

This setup ensures secure, scalable routing via the DLB.
