Question 1

A Mule application uses the Database connector.

What condition can the Mule application automatically adjust to or recover from without needing to restart or redeploy the Mule application?

A : One of the stored procedures being called by the Mule application has been renamed

B : The database server was unavailable for four hours due to a major outage but is now fully operational again

C : The credentials for accessing the database have been updated and the previous credentials are no longer valid

D : The database server has been updated and hence the database driver library/JAR needs a minor version upgrade

Answer: B

Question 2

When designing an upstream API and its implementation, the development team has been advised to not set timeouts when invoking downstream API. Because the downstream API has no SLA that can be relied upon. This is the only donwstream API dependency of that upstream API. Assume the downstream API runs uninterrupted without crashing. What is the impact of this advice?

A : The invocation of the downstream API will run to completion without timing out.

B : An SLA for the upstream API CANNOT be provided.

C : A default timeout of 500 ms will automatically be applied by the Mule runtime in which the upstream API implementation executes.

D : A load-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the downstream API implementation executes.

Answer: B

Question 3

Refer to the exhibit.

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?

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

Answer: D

Question 4

A team has completed the build and test activities for a Mule application that implements a System API for its application network.

Which Anypoint Platform component should the team now use to both deploy and monitor the System AP\ implementation?

A : API Manager

B : Design Center

C : Anypoint Exchange

D : Runtime Manager

Answer: D

Question 5

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 authorize the certificate to be used both APIs

B : To enable communication from each API's Mule Runtimes and Network zone to the load balancer of the other API

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
