Question 6

One of the backend systems involved by the API implementation enforces rate limits on the number of request a particle client can make.

Both the back-end system and API implementation are deployed to several non-production environments including the staging environment and to a particular production environment. Rate limiting of the back-end system applies to all non-production environments.

The production environment however does not have any rate limiting.

What is the cost-effective approach to conduct performance test of the API implementation in the non-production staging environment?

Options:

A.

Including logic within the API implementation that bypasses in locations of the back-end system in the staging environment and invoke a Mocking service that replicates typical back-end system responses

Then conduct performance test using this API implementation

B.

Use MUnit to simulate standard responses from the back-end system.

Then conduct performance test to identify other bottlenecks in the system

C.

Create a Mocking service that replicates the back-end system's

production performance characteristics

Then configure the API implementation to use the mocking

service and conduct the performance test

D.

Conduct scaled-down performance tests in the staging environment against rate-limiting back-end system. Then upscale performance results to full production scale

Question 7

What Mule application can have API policies applied by Anypoint Platform to the endpoint exposed by that Mule application?

C.

A Mule application that accepts JSON requests over WebSocket

D.

A Mule application that accepts gRPC requests over HTTP/2

Question 8

Options:

A.

Custom circuit breaker

B.

Client ID enforcement

C.

Rate limiting

D.

JSON threat protection

Question 10

An organization has strict unit test requirement that mandate every mule application must have an MUnit test suit with a test case defined for each flow and a minimum test coverage of 80%.

A developer is building Munit test suit for a newly developed mule application that sends API request toanexternal rest API.

What is the effective approach for successfully executing the Munit tests of this new application while still achieving the required test coverage for the Munit tests?

Options:

A.

Invoke the external endpoint of the rest API from the mule floors

B.

Mark the rest API invocations in the Munits and then call the mocking service flow that simulates standard responses from the REST API

C.

Mock the rest API invocation in the Munits and return a mock response for those invocations

D.

Create a mocking service flow to simulate standard responses from the rest API and then configure the mule flows to call the marking service flow
