Mule applications need to be deployed to CloudHub so they can access on-premises database
systems. These systems store sensitive and hence tightly protected data, so are not accessible over
the internet.
What network architecture supports this requirement?
Select the answer
1 correct answer
A.
An Anypoint VPC connected to the on-premises network using an IPsec tunnel or AWS
DirectConnect, plus matching firewall rules in the VPC and on-premises network
B.
Static IP addresses for the Mule applications deployed to the CloudHub Shared Worker Cloud, plus
matching firewall rules and IP
whitelisting in the on-premises network
C.
An Anypoint VPC with one Dedicated Load Balancer fronting each on-premises database system,
plus matching IP whitelisting in the load balancer and firewall rules in the VPC and on-premises
network
D.
Relocation of the database systems to a DMZ in the on-premises network, with Mule applications
deployed to the CloudHub Shared Worker Cloud connecting only to the DMZ

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.

certificate when deploying these Mule applications, so the disruption caused by certificate rotation is
minimized?

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

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
D.
Package the HTTPS Listener configuration in a Mule DOMAIN project, referencing It from all Mule

An API client is implemented as a Mule application that includes an HTTP Request operation using a
default configuration. The HTTP Request operation invokes an external API that follows standard
HTTP status code conventions, which causes the HTTP Request operation to return a 4xx status code.
What is a possible cause of this status code response?
Select the answer
1 correct answer
A.
An error occurred inside the external API implementation when processing the HTTP request that
was received from the outbound HTTP Request operation of the Mule application
B.
The external API reported that the API implementation has moved to a different external endpoint
C.
The HTTP response cannot be interpreted by the HTTP Request operation of the Mule application
after it was received from the external API
D.
The external API reported an error with the HTTP request that was received from the outbound
HTTP Request operation of the Mule application

An XA transaction Is being configured that involves a JMS connector listening for Incoming JMS
messages. What is the meaning of the timeout attribute of the XA transaction, and what happens
after the timeout expires?
Select the answer
1 correct answer
A.
The time that is allowed to pass between committing the transaction and the completion of the
Mule flow After the timeout, flow processing triggers an error
B.
The time that Is allowed to pass between receiving JMS messages on the same JMS connection
After the timeout, a new JMS connection Is established
C.
The time that Is allowed to pass without the transaction being ended explicitly After the timeout,
the transaction Is forcefully rolled-back
D.
The time that Is allowed to pass for state JMS consumer threads to be destroyed After the
timeout, a new JMS consumer thread is created

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?
Select the answer
1 correct answer
A.
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)
B.
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
C.
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
D.
ALL item VM messages are processed AT MOST ONCE by ONE ARBITRARY CloudHub worker
This one CloudHub worker processes ALL 200 item VM messages

An organization uses a 2-node Mute runtime cluster to host one stateless API implementation. The
API is accessed over HTTPS through a load balancer that uses round-robin for load distribution.
Two additional nodes have been added to the cluster and the load balancer has been configured to
recognize the new nodes with no other change to the load balancer.
What average performance change is guaranteed to happen, assuming all cluster nodes are fully
operational?
Select the answer
1 correct answer
A.
50% reduction in the response time of the API
B.
100% increase in the throughput of the API
C.
50% reduction In the JVM heap memory consumed by each node
D.
50% reduction In the number of requests being received by each node

An integration Mule application is deployed to a customer-hosted multi-node Mule 4 runtime duster.
The Mule application uses a Listener operation of a JMS connector to receive incoming messages
from a JMS queue.
How are the messages consumed by the Mule application?
Select the answer
1 correct answer
A.
Depending on the JMS provider's configuration, either all messages are consumed by ONLY the
primary cluster node or else ALL messages are consumed by ALL cluster nodes
B.
Regardless of the Listener operation configuration, all messages are consumed by ALL cluster
nodes
C.
Depending on the Listener operation configuration, either all messages are consumed by ONLY the
primary cluster node or else EACH message is consumed by ANY ONE cluster node
D.
Regardless of the Listener operation configuration, all messages are consumed by ONLY the
primary cluster node

application to interact with these systems, assuming that Anypoint Connectors exist that implement
these interface technologies?

One of the backend systems invoked by an API implementation enforces rate limits on the number of
requests a particular client can make. Both the backend system and the API implementation are
deployed to several non-production environments in addition to production.
Rate limiting of the backend system applies to all non-production environments. The production
environment, however, does NOT have any rate limiting.
What is the most effective approach to conduct performance tests of the API implementation in a
staging (non-production) environment?
Select the answer
1 correct answer
A.
Create a mocking service that replicates the backend system's production performance
characteristics. Then configure the API implementation to use the mocking service and conduct the
performance tests
B.
Use MUnit to simulate standard responses from the backend system then conduct performance
tests to identify other bottlenecks in the system
C.
Include logic within the API implementation that bypasses invocations of the backend system in a
performance test situation. Instead invoking local stubs that replicate typical backend system
responses then conduct performance tests using this API Implementation
D.
Conduct scaled-down performance tests in the staging environment against the rate limited
backend system then upscale performance results to full production scale
