Salesforce Certified MuleSoft Developer II Sample Questions (Q26-Q31):

NEW QUESTION # 26
When a client and server are exchanging messages during the mTLS handshake, what is being agreed on during the cipher suite exchange?

Answer: D

Explanation:
A TLS cipher suite defines the cryptographic algorithms that the communicating parties use to protect the connection. During TLS negotiation, the client advertises cipher suites that it supports and the server selects a mutually supported suite according to the protocol version and its security configuration.
In TLS 1.2 and earlier, a cipher-suite name can identify several cryptographic components, including key- exchange/authentication mechanisms, the symmetric encryption algorithm, and integrity protection. TLS 1.3 expresses cipher suites differently, but the negotiated suite still determines the authenticated-encryption algorithm used to protect application traffic. MuleSoft's TLS documentation exposes cipher-suite configuration directly, including suites based on AES-GCM and ChaCha20-Poly1305.
The TLS protocol version is negotiated as part of the broader handshake but is conceptually distinct from choosing a cipher suite. Likewise, a public-key format is not what the cipher-suite exchange fundamentally selects, and "a protocol" is too general.
Among the provided choices, an encryption algorithm is therefore the technically correct description of what the cipher-suite negotiation establishes for protecting the session.
Reference topics: TLS handshake; cipher suites; symmetric encryption; AES-GCM; mTLS cryptographic negotiation.

NEW QUESTION # 27
A Mule application for processing orders must log the order ID for every log message output.
What is a best practice to enrich every log message with the order ID?

Answer: A

Explanation:
To enrich every log message with the order ID, the developer should use the Tracing module to set logging variables with a Mapped Diagnostic Context (MDC). The Tracing module allows adding custom key-value pairs to log messages using MDC variables. The developer can use Set Logging Variables operation to set the order ID as an MDC variable and then use it in any logger processor within the same thread or event. Reference: https://docs.mulesoft.com/tracing-module/1.0/tracing-module-reference#set-logging-variables


NEW QUESTION # 28
Refer to the exhibit.
What is the result of the Mule Maven Plugin configuration of the value of property its,keystorePassoword in CloudHub 2.0?

Answer: C

Explanation:
The result of the Mule Maven Plugin configuration of the value of property its,keystorePassword in CloudHub 2.0 is that Runtime Manager masks the value. This means that Runtime Manager hides or obscures the value from anyone who views it in Runtime Manager or Anypoint Platform. Reference: https://docs.mulesoft.com/runtime-manager/runtime-manager-agent-for-mule4#properties-tab


NEW QUESTION # 29
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: C

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.
Official documentation: https://docs.mulesoft.com/object-store-connector/latest/object-store-connector- reference


NEW QUESTION # 30
In a Mule project, Flow-1 contains a flow-ref to Flow-2 depends on data from Flow-1 to execute successfully.
Which action ensures the test suites and test cases written for Flow-1 and Flow-2 will execute successfully?

Answer: C

Explanation:
To ensure the test suites and test cases written for Flow-1 and Flow-2 will execute successfully, the developer should use a Set Event processor to pass the input that is needed by Flow-2, and keep the test cases for Flow-1 and Flow-2 independent. This way, the developer can isolate the testing of each flow and avoid coupling them together. Reference: https://docs.mulesoft.com/munit/2.3/munit-test-flow
