Question 1

A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity. The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms. If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?

Options :

A : Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete

B : Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds

C : Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries

D : No timeout is possible to meet the upstream API-s desired SLA; a different SLA must be negotiated with the first downstream API or invoke an alternative API

Answer: D

Question 2

What is not true about Mule Domain Project?

Options :

A : This allows Mule applications to share resources

B : Expose multiple services within the Mule domain on the same port

C : Only available Anypoint Runtime Fabric

D : Send events (messages) to other Mule applications using VM queues

Answer: C

Question 3

The ABC company has an Anypoint Runtime Fabric on VMs/Bare Metal (RTF-VM) appliance installed on its own customer-hosted AWS infrastructure. Mule applications are deployed to this RTF-VM appliance. As part of the company standards, the Mule application logs must be forwarded to an external log management tool (LMT). Given the company's current setup and requirements, what is the most idiomatic (used for its intended purpose) way to send Mule application logs to the external LMT?

Options :

A : In RTF-VM, install and configure the external LTM-s log-forwarding agent

B : In RTF-VM, edit the pod configuration to automatically install and configure an Anypoint Monitoring agent

C : In each Mule application, configure custom Log4j settings

D : In RTF-VM. configure the out-of-the-box external log forwarder

Answer: A

Question 4

An organization has strict unit test requirement that mandate every mule application must have an MUnit test suit with a test case defined for each flow and a minimum test coverage of 80%. A developer is building Munit test suit for a newly developed mule application that sends API request to an external rest API. What is the effective approach for successfully executing the Munit tests of this new application while still achieving the required test coverage for the Munit tests?

Options :

A : Invoke the external endpoint of the rest API from the mule floors

B : Mark the rest API invocations in the Munits and then call the mocking service flow that simulates standard responses from the REST API

C : Mock the rest API invocation in the Munits and return a mock response for those invocations

D : Create a mocking service flow to simulate standard responses from the rest API and then configure the mule flows to call the marking service flow

Answer: C

Question 5

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?

Options :

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
