Question 8

A Mule application contains a Batch Job scope with several Batch Step scopes. The Batch Job scope is configured with a batch block size of 25.

A payload with 4,000 records is received by the Batch Job scope.

When there are no errors, how does the Batch Job scope process records within and between the Batch Step scopes?

Options:

A.

The Batch Job scope processes multiple record blocks in parallel, and a block of 25 records can jump ahead to the next Batch Step scope over an earlier block of records

Each Batch Step scope is invoked with one record in the payload of the received Mule event

For each Batch Step scope, all 25 records within a block are processed in parallel

All the records in a block must be completed before the block of 25 records is avai

B.

The Batch Job scope processes each record block sequentially, one at a time

Each Batch Step scope is invoked with one record in the payload of the received Mule event

For each Batch Step scope, all 25 records within a block are processed sequentially, one at a time

All 4000 records must be completed before the blocks of records are available to the next Batch Step scope

C.

The Batch Job scope processes multiple record blocks in parallel, and a block of 25 records can jump ahead to the next Batch Step scope over an earlier block of records

Each Batch Step scope is invoked with one record in the payload of the received Mule event

For each Batch Step scope, all 25 records within a block are processed sequentially, one record at a time

All the records in a block must be completed before the bloc

D.

The Batch Job scope processes multiple record blocks in parallel

Each Batch Step scope is invoked with a batch of 25 records in the payload of the received Mule event

For each Batch Step scope, all 4000 records are processed in parallel

Individual records can jump ahead to the next Batch Step scope before the rest of the records finish processing in the current Batch Step scope

Question 9

An external API frequently invokes an Employees System API to fetch employee data from a MySQL database. The architect must design a caching strategy to query the database only when there Is an update to the Employees table or else return a cached response in order to minimize the number of redundant transactions being handled by the database.

Options:

A.

Use an On Table Row operation configured with the Employees table, call invalidate cache, and hardcode the new Employees data to cache. Use an object-store-caching-strategy and set the expiration interval to 1 hour.

B.

Use an On Table Row operation configured with the Employees table and cail invalidate cache. Use an object-store-caching-strategy and the default expiration interval.

C.

Use a Scheduler with a fixed frequency set to every hour to trigger an invalidate cache flow. Use an object-store-caching-strategy and the default expiration interval.

D.

Use a Scheduler with a fixed frequency set to every hour, triggering an invalidate cache flow. Use an object-store-caching-strategy and set the expiration interval to 1 hour.

Question 10

Which scalability option is the controller implementing?

Options:

A.

C.

D.

Question 11

A large life sciences customer plans to use the Mule Tracing module with the Mapped Diagnostic Context (MDC) logging operations to enrich logging in its Mule application and to improve tracking by providing more context in the Mule application logs. The customer also wants to improve throughput and lower the message processing latency in its Mule application flows.

After installing the Mule Tracing module in the Mule application, how should logging be performed in flows in Mule applications, and what should be changed In the log4j2.xml files?

Options:

A.

In the flows, add Mule Tracing module Set logging variable operations before any Core Logger components.

In log4j2.xml files, change the appender's pattern layout to use %MDC and then assign the appender to a Logger or Root element.

B.

In the flows, add Mule Tracing module Set logging variable operations before any Core

Logger components.

In log4j2.xmI files, change the appender’s pattern layout to use the %MDC placeholder and then assign the appender to an AsyncLogger element.

C.

In the flows, add Mule Tracing module Set logging variable operations before any Core

Logger components.

In log4j2.xmI files, change the appender’'s pattern layout to use %asyncLogger placeholder and then assign the appender to an AsyncLogger element.

D.

In the flows, wrap Logger components in Async scopes. In log4j2.xmI files, change the appender's pattern layout to use the %asyncLogger

placeholder and then assign the appender to a Logger or Root element.
