NEW QUESTION # 35
An organization is creating a set of new services that are critical for their business. The project team prefers using REST for all services but is willing to use SOAP with common WS-" standards if a particular service requires it.
What requirement would drive the team to use SOAP/WS-* for a particular service?
- A. Must support message acknowledgement and retry as part of the protocol
- B. Must use XML payloads for the service and ensure that it adheres to a specific schema
- C. Must publish and share the service specification (including data formats) with the consumers of the service
- D. Must secure the service, requiring all consumers to submit a valid SAML token
Answer: A
Explanation:
Security Assertion Markup Language (SAML) is an open standard that allows identity providers (IdP) to pass authorization credentials to service providers (SP).
SAML transactions use Extensible Markup Language (XML) for standardized communications between the identity provider and service providers.
SAML is the link between the authentication of a user's identity and the authorization to use a service.
WS-Security is the key extension that supports many authentication models including: basic username/password credentials, SAML, OAuth and more.
A common way that SOAP API's are authenticated is via SAML Single Sign On (SSO). SAML works by facilitating the exchange of authentication and authorization credentials across applications. However, there is no specification that describes how to add SAML to REST web services.

NEW QUESTION # 40
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 an OAS API specification in Design Center
- B. Create a RAML API specification using any text editor
- C. Create a WSDL specification using any XML editor
- D. Create a SOAP API specification in Design Center
Answer: C
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 # 41
An organization has various integrations implemented as Mule applications. Some of these Mule applications are deployed to custom hosted Mule runtimes (on-premises) while others execute in the MuleSoft-hosted runtime plane (CloudHub). To perform the Integra functionality, these Mule applications connect to various backend systems, with multiple applications typically needing to access the backend systems.
How can the organization most effectively avoid creating duplicates in each Mule application of the credentials required to access the backend systems?
- A. Create a Mule domain project that maintains the credentials as Mule domain-shared resources Deploy the Mule applications to the Mule domain, so the credentials are available to the Mule applications
- B. Configure or create a credentials service that returns the credentials for each backend system, and that is accessible from customer-hosted and MuleSoft-hosted Mule runtimes Have the Mule applications toad the properties at startup by invoking that credentials service
- C. Store the credentials in properties files in a shared folder within the organization's data center Have the Mule applications load properties files from this shared location at startup
- D. Segregate the credentials for each backend system into environment-specific properties files Package these properties files in each Mule application, from where they are loaded at startup
Answer: D
Explanation:
* "Create a Mule domain project that maintains the credentials as Mule domain-shared resources" is wrong as domain project is not supported in Cloudhub * We should Avoid Creating duplicates in each Mule application but below two options cause duplication of credentials - Store the credentials in properties files in a shared folder within the organization's data center. Have the Mule applications load properties files from this shared location at startup - Segregate the credentials for each backend system into environment-specific properties files. Package these properties files in each Mule application, from where they are loaded at startup So these are also wrong choices * Credentials service is the best approach in this scenario. Mule domain projects are not supported on CloudHub. Also its is not recommended to have multiple copies of configuration values as this makes difficult to maintain Use the Mule Credentials Vault to encrypt data in a .properties file. (In the context of this document, we refer to the .properties file simply as the properties file.) The properties file in Mule stores data as key-value pairs which may contain information such as usernames, first and last names, and credit card numbers. A Mule application may access this data as it processes messages, for example, to acquire login credentials for an external Web service. However, though this sensitive, private data must be stored in a properties file for Mule to access, it must also be protected against unauthorized - and potentially malicious - use by anyone with access to the Mule application
NEW QUESTION # 42
Refer to the exhibit. An organization is designing a Mule application to receive data from one external business partner. The two companies currently have no shared IT infrastructure and do not want to establish one. Instead, all communication should be over the public internet (with no VPN).
What Anypoint Connector can be used in the organization's Mule application to securely receive data from this external business partner?
- A. Object Store connector
- B. File connector
- C. SFTP connector
- D. VM connector
Answer: C
NEW QUESTION # 43
In Anypoint Platform, a company wants to configure multiple identity providers (IdPs) for multiple lines of business (LOBs). Multiple business groups, teams, and environments have been defined for these LOBs.
What Anypoint Platform feature can use multiple IdPs across the company's business groups, teams, and environments?
- A. Virtual private clouds
- B. MuleSoft-hosted (CloudHub) dedicated load balancers
- C. Permissions
- D. Client (application) management
Answer: B
Explanation:
To use a dedicated load balancer in your environment, you must first create an Anypoint VPC. Because you can associate multiple environments with the same Anypoint VPC, you can use the same dedicated load balancer for your different environments.
NEW QUESTION # 44
A banking company is developing a new set of APIs for its online business. One of the critical API's is a master lookup API which is a system API. This master lookup API uses persistent object store. This API will be used by all other APIs to provide master lookup data.
Master lookup API is deployed on two cloudhub workers of 0.1 vCore each because there is a lot of master data to be cached. Master lookup data is stored as a key value pair. The cache gets refreshed if they key is not found in the cache.
Doing performance testing it was observed that the Master lookup API has a higher response time due to database queries execution to fetch the master lookup data.
Due to this performance issue, go-live of the online business is on hold which could cause potential financial loss to Bank.
As an integration architect, which of the below option you would suggest to resolve performance issue?
- A. Add an additional Cloudhub worker to provide additional capacity
- B. Implement HTTP caching policy for all GET endpoints for the master lookup API and implement locking to synchronize access to object store
- C. Upgrade vCore size from 0.1 vCore to 0,2 vCore
- D. Implement HTTP caching policy for all GET endpoints for master lookup API
Answer: B
NEW QUESTION # 45
An organization has decided on a cloud migration strategy that aims to minimize the organization's own IT resources. Currently, the organization has all of its Mule applications running on its own premises and uses an on-premises load balancer that exposes all APIs under the base URL https://api.acme.com.
As part of the migration strategy, the organization plans to migrate all of its Mule applications and load balancer to CloudHub.
What is the most straight-forward and cost-effective approach to Mule application deployment and load balancing that preserves the public URLs?
- A. Deploy the Mule applications to CloudHub
Update the CNAME record for api.acme.com in the organization's DNS server pointing to the A record of the CloudHub Shared Load Balancer (SLB) Apply mapping rules in the SLB to map URLs to their corresponding Mule applications - B. For each migrated Mule application, deploy an API Proxy Mule application to CloudHub, with all applications under the control of a CloudHub dedicated load balancer (DLB) Update the CNAME record for api.acme.com in the organization's DNS server pointing to the A record of a CloudHub dedicated load balancer (DLB) Apply mapping rules in the DLB to map each API Proxy application to its corresponding Mule application
- C. Deploy the Mule applications to CloudHub
Create a CNAME record for api.acme.com in the CloudHub Shared Load Balancer (SLB) pointing to the A record of the on-premises load balancer Apply mapping rules in the SLB to map URLs to their corresponding Mule applications - D. Deploy the Mule applications to CloudHub

Answer: A
NEW QUESTION # 46
An Order microservice and a Fulfillment microservice are being designed to communicate with their dients through message-based integration (and NOT through API invocations).
The Order microservice publishes an Order message (a kind of command message) containing the details of an order to be fulfilled. The intention is that Order messages are only consumed by one Mute application, the Fulfillment microservice.
The Fulfilment microservice consumes Order messages, fulfills the order described therein, and then publishes an OrderFulfilted message (a kind of event message). Each OrderFulfilted message can be consumed by any interested Mule application, and the Order microservice is one such Mute application.
What is the most appropriate choice of message broker(s) and message destination(s) in this scenario?
- A. Order messages are sent to a JMS queueOrderFulfilled messages are sent to a JMS topicBoth microservices Interact with the same JMS provider (message broker) Instance, which must therefore scale to support the load of both microservices
- B. O Order messages are sent to an Anypoint MQ exchange
OrderFulfilted messages are sent to an Anypoint MQ queue
Both microservices interact with Anypoint MQ as the message broker, which must therefore scale to support the toad of both microservices - C. Older messages are sent directly to the Fulfillment microservices
OrderFulfilled messages are sent directly to the Order microservice
The Order microserviceInteracts with one AMQP-compatible message broker and the Fulfillment microservice Interactswith a different AMQP-compatible message broker, so that both message brokers can be chosen and scaled to best support the toad each microservice - D. Order messages are sent to a JMS queueOrderFulfilled messages are sent to a JMS topic The Order microservice Interacts with one JMS provider (message broker) and the Fulfillment microservice interacts with a different JMS provider, so that both message brokers can be chosen and scaled to best support the load of each microservice
Answer: A
NEW QUESTION # 47
A rale limiting policy has been applied to a soap VI.2 API published in Clondhub. The API implementation catches errors in a global error handler on error propagate in the main flow for HTTP: RETRY_EXHAUSTED with HTTP status set to 429 and any with the HTTP status set to 500.
What is the expected H1TP status when the client exceeds the quota of the API calls?
- A. HTTP status 400 from the rate-limiting policy violation since the call does not reach the back-end
- B. HTTP status 401 unauthorized for policy violation
- C. HTTP status 429 as defined in the HTTP:RETRY EXHAUSTED error handler in the API B. HTTP status 500 as defined in the ANY error handler in the API since an API:RETRY_EXHAUSTED will be generated
Answer: C

This connector exposes convenient operations via SOAP for exploiting the capabilities of Salesforce Marketing Cloud.
NEW QUESTION # 49
Refer to the exhibit. A Mule 4 application has a parent flow that breaks up a JSON array payload into 200 separate items, then sends each item one at a time inside an Async scope to a VM queue.
A second flow to process orders has a VM Listener on the same VM queue. The rest of this flow processes each received item by writing the item to a database.
This Mule application is deployed to four CloudHub workers with persistent queues enabled.
What message processing guarantees are provided by the VM queue and the CloudHub workers, and how are VM messages routed among the CloudHub workers for each invocation of the parent flow under normal operating conditions where all the CloudHub workers remain online?
- A. ALL item VM messages are processed AT LEAST ONCE by the SAME CloudHub worker where the parent flow was invoked This one CloudHub worker processes ALL 200 item VM messages
- B. ALL item VM messages are processed AT MOST ONCE by ONE ARBITRARY CloudHub worker This one CloudHub worker processes ALL 200 item VM messages
- C. EACH item VM message is processed AT MOST ONCE by ONE CloudHub worker, with workers chosen in a deterministic round-robin fashion Each of the four CloudHub workers can be expected to process 1/4 of the item VM messages (about 50 items)
- D. EACH item VM message is processed AT LEAST ONCE by ONE ARBITRARY CloudHub worker Each of the four CloudHub workers can be expected to process some item VM messages
Answer: A
NEW QUESTION # 50
An external REST client periodically sends an array of records in a single POST request to a Mule application API endpoint.
The Mule application must validate each record of the request against a JSON schema before sending it to a downstream system in the same order that it was received in the array Record processing will take place inside a router or scope that calls a child flow. The child flow has its own error handling defined. Any validation or communication failures should not prevent further processing of the remaining records.
To best address these requirements what is the most idiomatic(used for it intended purpose) router or scope to used in the parent flow, and what type of error handler should be used in the child flow?
- A. For Each scope in the parent flow
On Error Continue error handler in the child flow - B. Until Successful router in the parent flow
On Error Propagate error handler in the child flow - C. First Successful router in the parent flow
On Error Continue error handler in the child flow - D. Parallel For Each scope in the parent flow
On Error Propagate error handler in the child flow
Answer: A
Explanation:
Correct answer is For Each scope in the parent flow On Error Continue error handler in the child flow. You can extract below set of requirements from the question a) Records should be sent to downstream system in the same order that it was received in the array b) Any validation or communication failures should not prevent further processing of the remaining records First requirement can be met using For Each scope in the parent flow and second requirement can be met using On Error Continue scope in child flow so that error will be suppressed.
