NEW QUESTION # 21
Refer to the exhibits.
The
flow is invoking a target API. The API's protocol is HTTPS. The TLS configuration in the HTTP Request Configuration global element is set to None. A web client submits a request to http://localhost:8081/vehicles.
If the certificate of the target API is signed by a certificate authority (CA), what is true about the HTTP Request operation when the flow executes?
Exhibit:
Answer: D
Explanation:
The HTTP Request connector is operating as a TLS client when it connects to the target HTTPS API. During the TLS handshake, the server presents its certificate chain. The client must be able to establish a chain of trust from that certificate to a trusted certificate authority.
When no custom Mule truststore is configured, Mule relies on the default Java/JRE truststore. MuleSoft explicitly states that if a tls:trust-store is not specified, Mule uses Java's default truststore, which normally contains certificates for major public certificate authorities.
Therefore, the target API connection succeeds when the issuing CA can be validated through that JRE truststore, assuming the remainder of the TLS negotiation is valid. A keystore serves a different purpose: it normally contains a private key and certificate used to establish the local party's own identity. It is not the default repository used to establish trust in remote HTTPS servers.
The connection also does not automatically trust every CA. Certificate validation still occurs unless validation is explicitly disabled.
Therefore, B correctly describes Mule's behavior when the HTTP Request configuration has no custom TLS truststore configured.
Reference topics: HTTP Request Connector; TLS client validation; Java default truststore; CA certificate chains; keystore versus truststore.

NEW QUESTION # 22
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 # 23
Refer to the exhibit.
A developer generates the base scaffolding for an API in Anypoint Studio.
Which HTTP status code is returned while testing using the API Kit console if no values are entered in client- id and client-secret?
Exhibit:
Answer: D
Explanation:
The RAML trait shown in the exhibit declares client_id and client_secret as headers and applies that trait to the /customers resource. Because these headers form part of the API contract, APIkit Router validates the inbound request against the specification before routing it to the generated implementation flow.
If the required request structure is not honored, APIkit raises an APIKIT:BAD_REQUEST error. MuleSoft's APIkit error-handling reference maps APIKIT:BAD_REQUEST directly to HTTP 400, and APIkit scaffolding generates the corresponding error-handling logic with httpStatus set to 400.
A 403 response would normally represent a request that was understood but rejected because of authorization.
That is not what is happening here: the request fails API contract validation before successful routing because required request information is absent. A 500 indicates an internal server failure, which is also inappropriate for malformed client input.
Therefore, when the API Console submits the request without the required header values, the APIkit- generated implementation treats it as a bad request and returns HTTP 400.
Reference topics: APIkit Router validation; RAML traits; required headers; APIKIT:BAD_REQUEST; APIkit-generated error handling.

NEW QUESTION # 24
When a client and server are exchanging messages during the mTLS handshake, what is being agreed on during the cipher suite exchange?
Answer: A
Explanation:
A cipher suite is a set of cryptographic algorithms that are used to secure the communication between a client and a server. A cipher suite consists of four components: a key exchange algorithm, an authentication algorithm, an encryption algorithm, and a message authentication code (MAC) algorithm. During the cipher suite exchange, the client and the server agree on which encryption algorithm to use for encrypting and decrypting the data.

NEW QUESTION # 25
Refer to the exhibits.
BioInfo System API is implemented and published to Anypoint Exchange. A developer wants to invoke this API using its REST Connector.
What should be added to the POM?
Exhibit / Answer Configurations:
Answer: C
Explanation:
REST Connect converts a supported REST API specification published in Anypoint Exchange into a Mule 4 connector. MuleSoft states that REST Connect-generated Mule 4 connectors are produced as connector artifacts and can be used in Studio like other Mule connectors.
A Mule connector is consumed by an application through the project's Maven dependencies, not through the Maven build-plugin section. MuleSoft's standard connector Maven model requires the connector's Exchange groupId, artifactId, and version under < dependency > , together with:
< classifier > mule-plugin < /classifier >
The classifier is essential because it identifies the artifact as a Mule extension/plugin that the Mule runtime must load. MuleSoft's connector Maven documentation provides this exact dependency structure and directs developers to Exchange's Dependency Snippets for the current coordinates.
A < plugin > declaration is for Maven build plugins rather than runtime Mule connectors. < repository > merely defines where Maven can resolve artifacts and does not itself add the connector to the application. < rest-connect > is not the POM dependency element used to consume a generated connector.
Reference topics: REST Connect; Anypoint Exchange generated connectors; Maven dependencies; mule- plugin classifier.
