Salesforce Certified MuleSoft Developer II Sample Questions (Q13-Q18):

NEW QUESTION # 13
Refer to the exhibit.
A Mule Object Store is configured with an entry TTL of one second and an expiration interval of 30 seconds.
What is the result of the flow if processing between os:store and os:retrieve takes 10 seconds?
Exhibit:

Answer: B

Explanation:
The distinction between entry TTL and expiration interval is the key to this question. entryTtl="1" specifies that an Object Store entry becomes eligible for expiration after one second. However, expirationInterval="30" determines how frequently Mule's expiration process checks the Object Store and removes expired entries.
MuleSoft describes the expiration interval as the frequency at which the expiration thread runs. Therefore, expiration is not equivalent to immediate physical removal at precisely the TTL boundary.
The flow first sets the payload to originalPayload, then stores "testPayload" under the key testKey. Ten seconds subsequently elapse before the Retrieve operation executes. Although this exceeds the configured one-second TTL, only 10 seconds have elapsed since storage, while the expiration process is configured to run at 30-second intervals. The entry has therefore not yet been evicted when retrieval occurs.
Because testKey remains available, os:retrieve returns the stored value, testPayload. The configured default value nullPayload would be used only if the key were unavailable according to the Retrieve operation's behavior.
Reference topics: Object Store Connector; entry TTL; expiration interval; expiration thread; Store and Retrieve operations.

NEW QUESTION # 14
A Mule implementation uses an HTTP Request within an Until Successful scope to connect to an API.
How should a permanent error response like HTTP:UNAUTHORIZED be handled inside Until Successful to reduce latency?

Answer: B

Explanation:
Until Successful is intended for failures that can reasonably succeed when retried, such as temporary connectivity issues or transient downstream unavailability. Mule executes the processors in the scope repeatedly until processing succeeds or the configured retry count is exhausted. If an error continues to propagate from the scope, Mule performs another attempt and ultimately raises MULE:
RETRY_EXHAUSTED after all retries fail.
An HTTP:UNAUTHORIZED response represents a permanent application/security condition for the current request. Repeating the identical request does not normally repair invalid credentials or insufficient authorization and simply increases latency and downstream traffic.
The HTTP Request should therefore be placed inside a Try scope. An On Error Continue handler specifically catches the permanent error and handles it inside that Try scope. Because the error is consumed rather than propagated, the Until Successful scope does not interpret the attempt as a retryable failure.
Using On Error Propagate would have the opposite effect: the error would escape the Try scope and cause Until Successful to retry. Continuing until MULE:RETRY_EXHAUSTED unnecessarily delays the response.
Reference topics: Until Successful Scope; Try Scope; On Error Continue; permanent versus transient errors; MULE:RETRY_EXHAUSTED.

NEW QUESTION # 15
A Mule application includes a subflow containing a Scatter-Gather scope. Within each leg of the Scatter- Gather, an HTTP connector calls a PUT endpoint to modify records in different upstream systems. The subflow is called from inside an Until Successful scope to retry if a transient exception is raised.
A technical spike is being performed to increase reliability of the Mule application.
Which steps should be performed within the Mule flow above to ensure idempotent behavior?

Answer: A

Explanation:
The relevant property is the HTTP semantics of PUT. PUT is designed to be idempotent: repeating the same request against the same resource should establish the same intended resource state rather than repeatedly creating additional side effects. This characteristic makes PUT appropriate when an Until Successful scope might retransmit an operation following a transient failure.
For example, the downstream system might process the initial PUT successfully but the Mule application might experience a network error before receiving the response. Until Successful could therefore invoke the same PUT again. Provided the upstream APIs correctly implement standard PUT semantics, repeating the same modification produces the intended final state rather than duplicating the operation.
Changing PUT to POST would generally make the design less suitable because POST is not inherently idempotent. Executing the operations sequentially changes concurrency but does not itself establish idempotency. Compensating transactions address distributed rollback and consistency when independent operations partially succeed; they are a different reliability concern from idempotent retry behavior.
MuleSoft documents Until Successful as retrying the contained processors until they succeed or retries are exhausted.
Therefore, under the REST/HTTP semantics assumed by the question, no additional Mule processing is required.
Reference topics: Until Successful; idempotent operations; HTTP PUT semantics; reliable retries; Scatter- Gather.

NEW QUESTION # 16
Refer to the exhibit.
A Mute Object Store is configured with an entry TTL of one second and an expiration interval of 30 seconds.
What is the result of the flow if processing between os'store and os:retrieve takes 10 seconds?

Answer: D

Explanation:
The result of the flow is nullPayload if processing between os:store and os:retrieve takes 10 seconds. This is because the entry TTL of the object store is one second, which means that any stored value expires after one second and is removed from the object store. The expiration interval of 30 seconds only determines how often the object store checks for expired values, but it does not affect the TTL. Therefore, when os:retrieve tries to get the value after 10 seconds, it returns nullPayload because the value has already expired and been removed.

NEW QUESTION # 17
A developer deploys an API to CloudHub and applies an OAuth policy on API Manager. During testing, the API response is slow, so the developer reconfigures the API so that the out-of-the-box HTTP Caching policy is applied first, and the OAuth API policy is applied second.
What will happen when an HTTP request is received?

Answer: D

Explanation:
When an HTTP request is received and the HTTP Caching policy is applied first, it checks if there is a cached response for that request in Object Store. If there is a cache hit, meaning that a valid cached response exists, then only the HTTP Caching policy is evaluated and the cached response is returned to the caller without invoking the OAuth policy or the API implementation. If there is a cache miss, meaning that no valid cached response exists, then both the HTTP Caching policy and the OAuth policy are evaluated before invoking the API implementation.
