Question 1

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?

A : Underlying Mule applications need to implement own certificates

B : Only MuleSoft provided certificates can be used for server side certificate

C : Only self signed certificates can be used

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

Answer: B

Question 2

An organization plans to extend its Mule APIs to the EU (Frankfurt) region. Currently, all Mule applications are deployed to CloudHub 1.0 in the default North American region, from the North America control plane, following this naming convention: {API-name}—{environment} (for example, Orderssapi—dev, Orders-sapi-—qa, Orders-sapi-—prod, etc.). There is no network restriction to block communications between APIs. What strategy should be implemented in order to deploy the same Mule APIs to the CloudHub 1.0 EU region from the North America control plane, as well as to minimize latency between APIs and target users and systems in Europe?

A : In Runtime Manager, for each Mule application deployment, set the Region property to EU (Frankfurt) and reuse the same Mule application mame as in the North American region. Communicate the new urls {API-name}—{environment}.de-ci.cloudhub.io to the consuming API clients In Europe.

B : In API Manager, set the Region property to EU (Frankfurt) to create an API proxy named {API-name}—proxy—{environment} for each Mule application. Communicate the new url {API-name}—proxy—{environment}.de-c1.cloudhub.io to the consuming API clients In Europe.

C : In Runtime Manager, for each Mule application deployment, leave the Region property blank (default) and change the Mule application name to {API-name}— {environment).de-cl. Communicate the new urls {API-name}—{environment}.de-ci1.cloudhub.io to the consuming API clients in Europe

D : In API Manager, leave the Region property blank (default) to deploy an API proxy named {API-name}~proxy~- (environment}.de-cl for each Mule application. Communicate the new url {API-name}—proxy—{environment}.de-cl.cloudhub.io to the consuming API clients in Europe.

Answer: A

Question 3

Which Salesforce API is invoked to deploy, retrieve, create or delete customization information such as custom object definitions using a Mule Salesforce connector in a Mule application?

A : Metadata API

B : REST API

C : SOAP API

D : Bulk API

Answer: A

Question 4

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 : A new load balancer must be provisioned to allow traffic to the new nodes in a round-robin fashion

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 : New firewall rules must be configured to accommodate communication between API clients and the new nodes

Answer: B

Question 5

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 : First Successful router in the parent flow On Error Continue error handler in the child flow

B : For Each scope in the parent flow On Error Continue error handler in the child flow

C : Parallel For Each scope in the parent flow On Error Propagate error handler in the child flow

D : Until Successful router in the parent flow On Error Propagate error handler in the child flow

Answer: B
