NEW QUESTION # 29
A Mule application need to invoice an API hosted by an external system to initiate a process. The external API takes anywhere between one minute and 24 hours to compute its process.
Which implementation should be used to get response data from the external API after it completes processing?
Answer: C
Explanation:
To get response data from the external API after it completes processing, the developer should expose an HTTP callback API in Mule and register it with the external system. This way, the external API can invoke the callback API with the response data when it is ready, instead of making the Mule application wait for a long time or poll for a response repeatedly. Reference: https://docs.mulesoft.com/mule-runtime/4.3/http-listener-ref#callback
NEW QUESTION # 30
Two APIs are deployed to a two-node on-prem cluster. Due to a requirements change, the two APIs must communicate to exchange data asynchronously.
Answer: C
Explanation:
To communicate asynchronously between two APIs deployed to a two-node on-prem cluster, the developer can use the VM Connector if the two APIs use the same domain. The VM Connector allows passing messages between different Mule applications within a single Mule runtime instance or across different instances using shared memory or persistent storage. If two APIs are deployed under the same domain, they can share resources such as VM queues and communicate asynchronously using VM Connector operations.

NEW QUESTION # 31
A Mule application deployed to multiple Cloudhub 2.0 replicas needs to temporarily persist large files over 10MB between flow executions, and routinely needs to query whether the file data exists on separate executions.
How can this be achieved?
Answer: D
Explanation:
To temporarily persist large files over 10MB between flow executions, and routinely query whether the file data exists on separate executions, the developer should store the contents of the file on separate storage, and store the key and location of the file object using Object Store v2. This way, the developer can avoid storing large files in memory or exceeding the size limit of Object Store v2 (10MB per object). The developer can also use Object Store v2 operations to query, retrieve, or delete the file object by its key. Reference: https://docs.mulesoft.com/object-store/osv2-faq#can-i-store-files-in-object-store-v2
NEW QUESTION # 32
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: A
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 # 33
What is the MuleSoft recommended method to encrypt sensitive property data?
Answer: C
Explanation:
The MuleSoft recommended method to encrypt sensitive property data is to use the Secure Properties Tool that comes with Anypoint Studio. This tool allows encrypting properties files with a secret key and then decrypting them at runtime using the same key. The encryption key and sensitive data should be different for each environment to ensure security and avoid accidental exposure of sensitive data. Reference: https://docs.mulesoft.com/mule-runtime/4.3/secure-configuration-properties
