Question 1

Which statement is true when using XML SDK for creating custom message processors?

AProperties are fields defined by an end user of the XML SDK component and serve as a global configuration for the entire Mule project in which they are used

BAn XML SDK provides both inbound and outbound operations

COperations can be reused in recursive calls

DAll operations are public

Answer : A

When using XML SDK for creating custom message processors, all operations are public by default and can be used by any Mule application that imports them. There is no way to make an operation private or protected in XML SDK. Reference: https://docs.mulesoft.com/mule-sdk/1.1/xml-sdk#operations

Question 2

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?

AChain together the test suites and test cases for Flow-1 and Flow-2

BUse ''Set Event to pass the input that is needed, and keep the test cases for Flow-1 and Flow-2 independent

CUse ''Before Test Case'' To collect data from Flow-1 test cases before running Flow-2 test cases

DUse 'After Test Case' to produce the data needed from Flow-1 test cases to pass to Flow-2 test cases

Answer : B

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

Question 3

A healthcare portal needs to validate the token that it sends to a Mule API. The developer plans to implement a custom policy using the HTTP Policy Transform Extension to match the token received in the header from the heathcare portal.

Which files does the developer need to create in order to package the custom policy?

ADeployable ZIP file, YAML configuration file

BJSON properties file, YAML configuration file

CJSON properties file, XML template file

DXML template file, YAML configuration file

Answer : D

To package a custom policy using the HTTP Policy Transform Extension, the developer needs to create an XML template file and a YAML configuration file. The XML template file defines the policy logic using Mule components and placeholders for user-defined properties. The YAML configuration file defines the metadata of the policy, such as its name, description, category, parameters, and dependencies. Reference: https://docs.mulesoft.com/api-manager/2.x/http-policy-transform#packaging-the-policy

Question 4

What is the MuleSoft recommended method to encrypt sensitive property data?

AThe encryption key and sensitive data should be different for each environment

BThe encryption key should be identical for all environments

CThe encryption key should be identical for all environments and the sensitive data should be different for each environment

DThe encryption key should be different for each environment and the sensitive data should be the same for all environments

Answer : A

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.

Question 5

Which statement is true about using mutual TLS to secure an application?

AMutual TLS requires a hardware security module to be used

BMutual TLS authenticates the identity of the server before the identity of the client

CMutual TLS ensures only authorized end users are allowed to access an endpoint

DMutual TLS increases the encryption strength versus server-side TLS alone

Answer : B

Mutual TLS (mTLS) is an extension of TLS that requires both parties (client and server) to present their certificates to each other during the handshake process. This way, both parties can verify each other's identity and establish a secure connection. The authentication of the server happens before the authentication of the client, as the server sends its certificate first and then requests the client's certificate. Reference: https://docs.mulesoft.com/mule-runtime/4.3/tls-configuration#mutual-authentication

Question 6

Refer to the exhibit.

What action must be performed to log all the errors raised by the VM Connector?

AAdd <AsyncLOgger name='orgroute.extensions vm' level=ERROR'I> inside the Logger tag

BAdd <AsyncLOgger name='orgroute.extensions vm' level=ERROR'/> inside the Appenders tag

CConfigure <Logger level-'ERROR'/> inside the VM Connector configuration

DNothing, as error-level events are automatically logged

Answer : B

To log all the errors raised by the VM Connector, the developer needs to add an async logger with the name 'org.mule.extension.vm' and the level 'ERROR' inside the appenders tag of the log4j2.xml file. This will enable logging all error-level events generated by the VM Connector to the console appender. Reference: https://docs.mulesoft.com/mule-runtime/4.3/logging-in-mule#configuring-custom-logging-settings

Question 7

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?

AIn case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; then the cached response is returned to the caller

BIn case of a cache it, only the HTTP Caching policy is evaluating; then the cached response is returned to the caller

CIn case of a cache miss, only the HTTP Caching policy is evaluated; then the API retrieves the data from the API implementation, and the policy stores the data to be cached in Object Store

DIn case of a cache miss, both the OAuth and HTTP Caching policies are evaluated; then the API retrieves the data from the API implementation, and the policy does not store the data in Object Store

Answer : B

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.
