NEW QUESTION # 21
A travel company wants to publish a well-defined booking service API to be shared with its business partners. These business partners have agreed to ONLY consume SOAP services and they want to get the service contracts in an easily consumable way before they start any development. The travel company will publish the initial design documents to Anypoint Exchange, then share those documents with the business partners. When using an API-led approach, what is the first design document the travel company should deliver to its business partners?
- A. Create a SOAP API specification in Design Center
- B. Create a RAML API specification using any text editor
- C. Create an OAS API specification in Design Center
- D. Create a WSDL specification using any XML editor
Answer: D
Explanation:
SOAP API specifications are provided as WSDL. Design center doesn't provide the functionality to create WSDL file. Hence WSDL needs to be created using XML editor
NEW QUESTION # 22

- A. Object Store connector
- B. VM connector
- C. File connector
- D. SFTP connector
Answer: D
NEW QUESTION # 23
Refer to the exhibit.
An organization is sizing an Anypoint VPC for the non-production deployments of those Mule applications that connect to the organization's on-premises systems. This applies to approx. 60 Mule applications. Each application is deployed to two CloudHub i workers. The organization currently has three non-production environments (DEV, SIT and UAT) that share this VPC. The AWS region of the VPC has two AZs.
The organization has a very mature DevOps approach which automatically progresses each application through all non-production environments before automatically deploying to production. This process results in several Mule application deployments per hour, using CloudHub's normal zero-downtime deployment feature.
What is a CIDR block for this VPC that results in the smallest usable private IP address range?
- A. 10.0.0.0/24 (256 IPs)
- B. 10.0.0.0/25 (128 IPs)
- C. 10.0.0.0/26 (64 IPS)
- D. 10.0.0.0/22 (1024 IPs)
Answer: D
NEW QUESTION # 24
An integration team uses Anypoint Platform and follows MuleSoft's recommended approach to full lifecycle API development.
Which step should the team's API designer take before the API developers implement the AP! Specification?
- A. Generate test cases using MUnit so the API developers can observe the results of running the API
- B. Use API Manager to version the API specification
- C. Publish the API specification to Exchange and solicit feedback from the API's consumers
- D. Use the scaffolding capability of Anypoint Studio to create an API portal based on the API specification
Answer: C
NEW QUESTION # 25
What aspect of logging is only possible for Mule applications deployed to customer-hosted Mule runtimes, but NOT for Mule applications deployed to CloudHub?
- A. To send Mule application log entries to Splunk
- B. To log certain messages to a custom log category
- C. To directly reference one shared and customized log4j2.xml file from multiple Mule applications
- D. To change tog4j2 tog levels in Anypoint Runtime Manager without having to restart the Mule application
Answer: C
Explanation:
* Correct answer is To directly reference one shared and customized log4j2.xml file from multiple Mule applications. Key word to note in the answer is directly.
* By default, CloudHub replaces a Mule application's log4j2.xml file with a CloudHub log4j2.xml file. This specifies the CloudHub appender to write logs to the CloudHub logging service.
* You cannot modify CloudHub log4j2.xml file to add any custom appender. But there is a process in order to achieve this. You need to raise a request on support portal to disable CloudHub provided Mule application log4j2 file.
* Once this is done , Mule application's log4j2.xml file is used which you can use to send/export application logs to other log4j2 appenders, such as a custom logging system MuleSoft does not own any responsibility for lost logging data due to misconfiguration of your own log4j appender if it happens by any chance.
* One more difference between customer-hosted Mule runtimes and CloudHub deployed mule instance is that
- CloudHub system log messages cannot be sent to external log management system without installing custom CH logging configuration through support
- where as Customer-hosted runtime can send system and application log to external log management system MuleSoft Reference:

NEW QUESTION # 26
Refer to the exhibit.
An organization deploys multiple Mule applications to the same customer -hosted Mule runtime. Many of these Mule applications must expose an HTTPS endpoint on the same port using a server-side certificate that rotates often.
What is the most effective way to package the HTTP Listener and package or store the server-side certificate when deploying these Mule applications, so the disruption caused by certificate rotation is minimized?
- A. Package the HTTPS Listener configuration in a Mule DOMAIN project, referencing it from all Mule applications that need to expose an HTTPS endpoint. Store the server-side certificate in a shared filesystem location in the Mule runtime's classpath, OUTSIDE the Mule DOMAIN or any Mule APPLICATION
- B. Package the HTTPS Listener configuration in a Mule DOMAIN project, referencing it from all Mule applications that need to expose an HTTPS endpoint Package the server-side certificate in ALL Mule APPLICATIONS that need to expose an HTTPS endpoint
- C. Package the HTTPS Listener configuration in a Mule DOMAIN project, referencing It from all Mule applications that need to expose an HTTPS endpoint. Package the server-side certificate in the SAME Mule DOMAIN project Go to Set
- D. Package an HTTPS Listener configuration In all Mule APPLICATIONS that need to expose an HTTPS endpoint Package the server-side certificate in a NEW Mule DOMAIN project
Answer: A
NEW QUESTION # 27
Refer to the exhibit.
A business process involves two APIs that interact with each other asynchronously over HTTP. Each API is implemented as a Mule application. API 1 receives the initial HTTP request and invokes API 2 (in a fire and forget fashion) while API 2, upon completion of the processing, calls back into API l to notify about completion of the asynchronous process.
Each API Is deployed to multiple redundant Mule runtimes and a separate load balancer, and is deployed to a separate network zone.
In the network architecture, how must the firewall rules be configured to enable the above Interaction between API 1 and API 2?
- A. To enable communication from each API's Mule Runtimes and Network zone to the load balancer of the other API
- B. To authorize the certificate to be used both APIs
- C. To open direct two-way communication between the Mule Runtimes of both API's
- D. To allow communication between load balancers used by each API
Answer: A
Explanation:
* If your API implementation involves putting a load balancer in front of your APIkit application, configure the load balancer to redirect URLs that reference the baseUri of the application directly. If the load balancer does not redirect URLs, any calls that reach the load balancer looking for the application do not reach their destination.
* When you receive incoming traffic through the load balancer, the responses will go out the same way. However, traffic that is originating from your instance will not pass through the load balancer. Instead, it is sent directly from the public IP address of your instance out to the Internet. The ELB is not involved in that scenario.
* The question says "each API is deployed to multiple redundant Mule runtimes", that seems to be a hint for self hosted Mule runtime cluster. Set Inbound allowed for the LB, outbound allowed for runtime to request out.
* Hence correct way is to enable communication from each API's Mule Runtimes and Network zone to the load balancer of the other API. Because communication is asynchronous one
NEW QUESTION # 28
Additional nodes are being added to an existing customer-hosted Mule runtime cluster to improve performance. Mule applications deployed to this cluster are invoked by API clients through a load balancer.
What is also required to carry out this change?
- A. New firewall rules must be configured to accommodate communication between API clients and the new nodes
- B. External monitoring tools or log aggregators must be configured to recognize the new nodes
- C. API implementations using an object store must be adjusted to recognize the new nodes and persist to them
- D. A new load balancer must be provisioned to allow traffic to the new nodes in a round-robin fashion

NEW QUESTION # 29
An organization is designing the following two Mule applications that must share data via a common persistent object store instance:
- Mule application P will be deployed within their on-premises datacenter.
- Mule application C will run on CloudHub in an Anypoint VPC.
The object store implementation used by CloudHub is the Anypoint Object Store v2 (OSv2).
what type of object store(s) should be used, and what design gives both Mule applications access to the same object store instance?
- A. Application P uses the Object Store connector to access a persistent object store Application C accesses this persistent object store via the Object Store REST API through an IPsec tunnel
- B. Application C and P both use the Object Store connector to access the Anypoint Object Store v2
- C. Application C uses the Object Store connector to access a persistent object Application P accesses the persistent object store via the Object Store REST API
- D. Application C and P both use the Object Store connector to access a persistent object store
Answer: C
NEW QUESTION # 30
Which productivity advantage does Anypoint Platform have to both implement and manage an AP?
- A. Automatic API semantic versioning

- C. Automatic API proxy generation
- D. Automatic API governance
Answer: D
NEW QUESTION # 31
The implementation of a Process API must change. What is a valid approach that minimizes the impact of this change on API clients?
- A. Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version
- B. Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanently to inform API clients they should be calling the new API implementation
- C. Implement required changes to the Process API implementation so that whenever possible, the Process API's RAML definition remains unchanged
- D. Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition
Answer: C
Explanation:
* Option B shouldn't be used unless extremely needed, if RAML is changed, client needs to accommodate changes. Question is about minimizing impact on Client. So this is not a valid choice.
* Option C isn't valid as Business can't stop for consumers acknowledgment.
* Option D again needs Client to accommodate changes and isn't viable option.
* Best choice is A where RAML definition isn't changed and underlined functionality is changed without any dependency on client and without impacting client.
NEW QUESTION # 32
Refer to the exhibit.
A Mule application isdeployed to a multi-node Mule runtime cluster. The Mule application uses the competing consumer pattern among its cluster replicas to receive JMS messages from a JMS queue. To process each received JMS message, the following steps are performed in a flow:
Step l: The JMS Correlation ID header is read from the received JMS message.
Step 2: The Mule application invokes an idempotent SOAP webservice over HTTPS, passing the JMS Correlation ID as one parameter in the SOAP request.
Step 3: The response fromthe SOAP webservice also returns the same JMS Correlation ID.
Step 4: The JMS Correlation ID received from the SOAP webservice is validated to be identical to the JMS Correlation ID received in Step 1.
Step 5: The Mule application creates aresponse JMS message, setting the JMS Correlation ID message header to the validated JMS Correlation ID and publishes that message to a response JMS queue.
Where should the Mule application store the JMS Correlation ID values received in Step 1 and Step 3so that the validation in Step 4 can be performed, while also making the overall Mule application highly available, fault-tolerant, performant, and maintainable?
- A. The Correlation ID value in Step 1 should be stored in a persistent object store The Correlation ID value in step 3 should be stored as a Mule event variable/attribute
- B. Both Correlation ID values should be stored in a persistent object store
- C. Both Correlation ID values should be stored In a non-persistent object store
- D. Both Correlation IDvalues should be stored as Mule event variable/attribute
Answer: D
