Mulesoft MCPA-Level-1 Exam Questions

A.   For read-only interactions to any dependencies (such as other web APIs)

Explanation:
MUnit is MuleSoft’s testing framework for creating and running automated tests within Anypoint Studio. It is specifically designed for unit testing Mule applications and is best suited when testing doesn’t require understanding the inner workings or implementation details of the components being tested.

• Ideal Use Cases for MUnit:
• Why Option B is Correct:
• Explanation of Incorrect Options:

B.   The Autodiscovery element is not present, in the deployed Mule application

Explanation:
When a Basic Authentication policy is applied to an API on CloudHub but clients can still access the API without authentication, the likely cause is a missing Autodiscovery element. Here’s how this affects API security:

• Autodiscovery in MuleSoft:
• Why Option B is Correct:
• Explanation of Incorrect Options:

References:
Refer to MuleSoft documentation on Autodiscovery configuration and linking API Manager policies for additional information on setting up secure API policies.

B.   

A higher number of discoverable API-related assets in the application network

Explanation: Explanation
Correct Answer: A higher number of discoverable API-related assets in the application
network.
*****************************************
>> We do NOT get faster response times in fine-grained approach when compared to
coarse-grained approach.
>> In fact, we get faster response times from a network having coarse-grained APIs
compared to a network having fine-grained APIs model. The reasons are below.
Fine-grained approach:
1. will have more APIs compared to coarse-grained
2. So, more orchestration needs to be done to achieve a functionality in business process.
3. Which means, lots of API calls to be made. So, more connections will needs to be
established. So, obviously more hops, more network i/o, more number of integration points
compared to coarse-grained approach where fewer APIs with bulk functionality embedded
in them.
4. That is why, because of all these extra hops and added latencies, fine-grained approach
will have bit more response times compared to coarse-grained.
5. Not only added latencies and connections, there will be more resources used up in finegrained
approach due to more number of APIs.
That's why, fine-grained APIs are good in a way to expose more number of resuable assets
in your network and make them discoverable. However, needs more maintenance, taking
care of integration points, connections, resources with a little compromise w.r.t network
hops and response times.

To invoke OAuth 2.0-protected APIs managed by Anypoint Platform, API clients must submit access tokens issued by that same Identity Provider

Explanation: https://www.folkstalk.com/2019/11/mulesoft-integration-and-platform.html
Explanation
Correct Answer: To invoke OAuth 2.0-protected APIs managed by Anypoint Platform, API
clients must submit access tokens issued by that same Identity Provider
*****************************************
>> It is NOT necessary that single sign-on is required to sign in to Anypoint Platform
because we are using an external Identity Provider for Client Management
>> It is NOT necessary that all APIs managed by Anypoint Platform must be protected by
SAML 2.0 policies because we are using an external Identity Provider for Client
Management
>> Not TRUE that the application network must include System APIs that interact with the
Identity Provider because we are using an external Identity Provider for Client Management
Only TRUE statement in the given options is - "To invoke OAuth 2.0-protected APIs
managed by Anypoint Platform, API clients must submit access tokens issued by that same
Identity Provider"

D.   To store key-value pairs with keys up to 300 characters

Explanation: CloudHub Object Store v2 is a managed key-value store provided by MuleSoft to support various use cases where temporary data storage is required. Here’s why Option D is correct:
Key Length Support: Object Store v2 allows storage of keys with a length of up to 300 characters, making it suitable for applications needing flexible and descriptive keys.
Limitations on Size:
Key-Value Limits: Object Store v2 is designed for moderate, transient storage needs, and does not support unlimited storage. Thus, Option A is incorrect.
Backward Compatibility: Object Store v2 does not support Mule 4 applications running Object Store v1. Option C is incorrect as Object Store v1 and v2 are distinct.

D.   

GET, OPTIONS, HEAD

A.   Runtime Manager

B.   Anypoint Platform CLI

C.   Platform APIs

Explanation:
MuleSoft offers various tools to automate the deployment of Mule applications, which can streamline deployment and management processes. Here’s how each tool supports automated deployment:

• Runtime Manager:
• Anypoint Platform CLI:
• Platform APIs:
• Explanation of Incorrect Options:

References:
For detailed steps on automating deployments with these tools, refer to MuleSoft documentation on Runtime Manager, CLI, and Platform APIs.
