Questions 8

A Mule application is being designed for deployment to a single CloudHub worker. The Mule application will have a flow that connects to a SaaS system to perform some operations each time the flow is invoked.

The SaaS system connector has operations that can be configured to request a short-lived token (fifteen minutes) that can be reused for subsequent connections within the fifteen minute time window. After the token expires, a new token must be requested and stored.

What is the most performant and idiomatic (used for its intended purpose) Anypoint Platform component or service to use to support persisting and reusing tokens in the Mule application to help speed up reconnecting the Mule application to the SaaS application?

Options:

A.

Nonpersistent object store

B.

Persistent object store

A mule application designed to fulfil two requirements

a) Processing files are synchronously from an FTPS server to a back-end database using VM intermediary queues for load balancing VM events

b) Processing a medium rate of records from a source to a target system using batch job scope

Considering the processing reliability requirements for FTPS files, how should VM queues be configured for processing files as well as for the batch job scope if the application is deployed to Cloudhub workers?

Options:

A.

Use Cloud hub persistent queues for FTPS files processing

There is no need to configure VM queues for the batch jobs scope as it uses by default the worker's disc for VM queueing

B.

Use Cloud hub persistent VM queue for FTPS file processing

There is no need to configure VM queues for the batch jobs scope as it uses by default the worker's JVM memory for VM queueing

C.

Use Cloud hub persistent VM queues for FTPS file processing

Disable VM queue for the batch job scope

D.

Use VM connector persistent queues for FTPS file processing Disable VM queue for the batch job scope

Questions 11

A company is designing an integration Mule application to process orders by submitting them to a back-end system for offline processing. Each order will be received by the Mule application through an HTTP5 POST and must be acknowledged immediately.

Once acknowledged the order will be submitted to a back-end system. Orders that cannot be successfully submitted due to the rejections from the back-end system will need to be processed manually (outside the banking system).

The mule application will be deployed to a customer hosted runtime and will be able to use an existing ActiveMQ broker if needed. The ActiveMQ broker is located inside the organization's firewall. The back-end system has a track record of unreliability due to both minor network connectivity issues and longer outages.

Which combination of Mule application components and ActiveMQ queues are required to ensure automatic submission of orders to the back-end system while supporting but minimizing manual order processing?

Options:

A.

One or more On Error scopes to assist calling the back-end system An Untill successful scope containing VM components for long retries A persistent dead-letter VM queue configure in Cloud hub

B.

An Until Successful scope to call the back-end system One or more ActiveMQ long-retry queues One or more ActiveMQ dead-letter queues for manual processing

C.

One or more on-Error scopes to assist calling the back-end system one or more ActiveMQ long-retry queues A persistent dead-letter Object store configuration in the CloudHub object store service

D.

A batch job scope to call the back in system An Untill successful scope containing Object Store components for long retries. A dead-letter object store configured in the Mule application

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

Options:

A.

In-memory non repeatable stream

B.

File based non-repeatable stream

C.

In-memory repeatable stream

Orders API truststore: The Orders API public key

Process Orders keystore: The Process Orders private key and public key

B.

Orders API truststore: The Orders API private key and public key

Process Orders keystore: The Process Orders private key public key

Questions 17

A banking company is developing a new set of APIs for its online business. One of the critical API's is a master lookup API which is a system API. This master lookup API uses persistent object store. This API will be used by all other APIs to provide master lookup data.

Master lookup API is deployed on two cloudhub workers of 0.1 vCore each because there is a lot of master data to be cached. Master lookup data is stored as a key value pair. The cache gets refreshed if they key is not found in the cache.

Doing performance testing it was observed that the Master lookup API has a higher response time due to database queries execution to fetch the master lookup data.

Due to this performance issue, go-live of the online business is on hold which could cause potential financial loss to Bank.

As an integration architect, which of the below option you would suggest to resolve performance issue?

Options:

A.

Implement HTTP caching policy for all GET endpoints for the master lookup API and implement locking to synchronize access to object store

B.

Upgrade vCore size from 0.1 vCore to 0,2 vCore

C.

Implement HTTP caching policy for all GET endpoints for master lookup API

D.

Add an additional Cloudhub worker to provide additional capacity
