Question 1

What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST API's, Anypoint CLI or the Mule Maven plugin?

ABy default, the Anypoint CLI and Mule Maven plugin are not included in the Mule runtime

BAccess to Anypoint Platform API;s and Anypoint CLI can be controlled separately thruough the roles and permissions in Anypoint platform, so that specific users can get access to Anypoint CLI while others get access to the platform API's

CAnypoint Platform API's can only automate interactions with CloudHub while the Mule maven plugin is required for deployment to customer hosted Mule runtimes

DAPI policies can be applied to the Anypoint platform API's so that only certain LOS's has access to specific functions

Answer : A

Correct answer is By default, the Anypoint CLI and Mule Maven plugin are not included in the Mule runtime Maven is not part of runtime though it is part of studio. You do not need it to deploy in order to deploy your app. Same is the case with CLI.

Question 2

An external web UI application currently accepts occasional HTTP requests from client web browsers to change (insert, update, or delete) inventory pricing information in an inventory system's database. Each inventory pricing change must be transformed and then synchronized with multiple customer experience systems in near real-time (in under 10 seconds). New customer experience systems are expected to be added in the future.

The database is used heavily and limits the number of SELECT queries that can be made to the database to 10 requests per hour per user.

What is the most scalable, idiomatic (used for its intended purpose), decoupled. reusable, and maintainable integration mechanism available to synchronize each inventory pricing change with the various customer experience systems in near real-time?

AWrite a Mule application with a Database On Table Row event source configured for the inventory pricing database, with the watermark attribute set to an appropriate database column
In the same now, use a Scatter-Gather to call each customer experience system's REST API with transformed inventory-pricing records

BAdd a trigger to the inventory-pricing database table so that for each change to the inventory pricing database, a stored procedure is called that makes a REST call to a Mule application
Write the Mule application to publish each Mule event as a message to an Anypoint MQ exchange
Write other Mule applications to subscribe to the Anypoint MQ exchange, transform each received message, and then update the Mule application's corresponding customer experience system(s)

CReplace the external web UI application with a Mule application to accept HTTP requests from client web browsers
In the same Mule application, use a Batch Job scope to test if the database request will succeed, aggregate pricing changes within a short time window, and then update both the inventory pricing database and each customer experience system using a Parallel For Each scope

DWrite a Mule application with a Database On Table Row event source configured for the inventory pricing database, with the ID attribute set to an appropriate database column
In the same flow, use a Batch Job scope to publish transformed Inventory-pricing records to an Anypoint MQ queue
Write other Mule applications to subscribe to the Anypoint MQ queue, transform each received message, and then update the Mule application's corresponding customer experience system(s)

Answer : B

Question 3

An organization is evaluating using the CloudHub shared Load Balancer (SLB) vs creating a CloudHub dedicated load balancer (DLB). They are evaluating how this choice affects the various types of certificates used by CloudHub deployed Mule applications, including MuleSoft-provided, customer-provided, or Mule application-provided certificates. What type of restrictions exist on the types of certificates for the service that can be exposed by the CloudHub Shared Load Balancer (SLB) to external web clients over the public internet?

AUnderlying Mule applications need to implement own certificates

BOnly MuleSoft provided certificates can be used for server side certificate

COnly self signed certificates can be used

DAll certificates which can be used in shared load balancer need to get approved by raising support ticket

Answer : B

Correct answer is Only MuleSoft provided certificates can be used for server side certificate

* The CloudHub Shared Load Balancer terminates TLS connections and uses its own server-side certificate.

* You would need to use dedicated load balancer which can enable you to define SSL configurations to provide custom certificates and optionally enforce two-way SSL client authentication.

* 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.

Question 4

An organization uses one specific CloudHub (AWS) region for all CloudHub deployments. How are CloudHub workers assigned to availability zones (AZs) when the organization's Mule applications are deployed to CloudHub in that region?

AWorkers belonging to a given environment are assigned to the same AZ within that region.

BAZs are selected as part of the Mule application's deployment configuration.

CWorkers are randomly distributed across available AZs within that region.

DAn AZ is randomly selected for a Mule application, and all the Mule application's CloudHub workers are assigned to that one AZ

Answer : C

Correct answer is Workers are randomly distributed across available AZs within that region. This ensure high availability for deployed mule applications Mulesoft documentation reference :

Question 5

When the mule application using VM is deployed to a customer-hosted cluster or multiple cloudhub workers, how are messages consumed by the Mule engine?

Ain non-deterministic way

Bby starting an XA transaction for each new message

Cin a deterministic way

Dthe primary only in order to avoid duplicate processing

Answer : C

Question 6

A system API EmployeeSAPI is used to fetch employee's data from an underlying SQL database.

The architect must design a caching strategy to query the database only when there is an update to the employees stable or else return a cached response in order to minimize the number of redundant transactions being handled by the database.

What must the architect do to achieve the caching objective?

AUse an On Table Row on employees table and call invalidate cache
Use an object store caching strategy and expiration interval to empty

BUse a Scheduler with a fixed frequency every hour triggering an invalidate cache flow
Use an object store caching strategy and expiration interval to empty

CUse a Scheduler with a fixed frequency every hour triggering an invalidate cache flow
Use an object store caching strategy and set expiration interval to 1-hour

DUse an on table rule on employees table call invalidate cache and said new employees data to cache
Use an object store caching strategy and set expiration interval to 1-hour

Answer : A

Question 7

An organization's security requirements mandate centralized control at all times over authentication and authorization of external applications when invoking web APIs managed on Anypoint Platform.

What Anypoint Platform feature is most idiomatic (used for its intended purpose), straightforward, and maintainable to use to meet this requirement?

AClient management configured in access management

BIdentity management configured in access management

CEnterprise Security module coded in Mule applications

DExternal access configured in API Manager
