MCIA-Level-1 Reviews Questions

Explanation

Correct answer is It is not possible to store logs for 2 years in CloudHub deployment. External log management system is required. CloudHub has a specific log retention policy, as described in the documentation: the platform stores logs of up to 100 MB per app & per worker or for up to 30 days, whichever limit is hit first. Once this limit has been reached, the oldest log information is deleted in chunks and is irretrievably lost. The recommended approach is to persist your logs to a external logging system of your choice (such as Splunk, for instance) using a log appender. Please note that this solution results in the logs no longer being stored on our platform, so any support cases you lodge will require for you to provide the appropriate logs for review and case resolution

Explanation

In Unit testing instead of using actual backends, stubs are used for the backend services. This ensures that developers are not blocked and have no dependency on other systems.

In Unit testing instead of using actual backends, stubs are used for the backend services. This ensures that developers are not blocked and have no dependency on other systems.

Below are the typical characteristics of unit testing.

-- Unit tests do not require deployment into any special environment, such as a staging environment

-- Unit tests san be run from within an embedded Mule runtime

-- Unit tests can/should be implemented using MUnit

-- For read-only interactions to any dependencies (such as other APIs): allowed to invoke production endpoints

-- For write interactions: developers must implement mocks using MUnit

-- Require knowledge of the implementation details of the API implementation under test

Explanation

* XA transaction add tremendous latency so "Reduce Latency" is incorrect option XA transactions define "All or No" commit protocol.

* Each local XA resource manager supports the A.C.I.D properties (Atomicity, Consistency, Isolation, and Durability).

So correct choice is "Ensure consistency"

Explanation

* Object Store and VM Store is used for sharing data inter or intra mule applications in same setup. Can't be used with external Business Partner

* Also File connector will not be useful as the two companies currently have no shared IT infrastructure. It's specific for local use.

* Correct answer is SFTP connector. The SFTP Connector implements a secure file transport channel so that your Mule application can exchange files with external resources. SFTP uses the SSH security protocol to transfer messages. You can implement the SFTP endpoint as an inbound endpoint with a one-way exchange pattern, or as an outbound endpoint configured for either a one-way or request-response exchange pattern.
