Salesforce Updated MuleSoft-Integration-Architect-I Exam Questions and Answers by elyas

Explanation

Correct answer is Application A accesses the persistent object store via the Object Store REST API Application B uses the Object Store connector to access a persistent object * Object Store v2 lets CloudHub applications store data and states across batch processes, Mule components and applications, from within an application or by using the Object Store REST API. * On-premise Mule applications cannot use Object Store v2. * You can select Object Store v2 as the implementation for Mule 3 and Mule 4 in CloudHub by checking the Object Store V2 checkbox in Runtime Manager at deployment time. * CloudHub Mule applications can use Object Store connector to write to the object store * The only way on-premises Mule applications can access Object Store v2 is via the Object Store REST API. * You can configure a Mule app to use the Object Store REST API to store and retrieve values from an object store in another Mule app.

Mocking REST API Invocations:

To ensure the unit tests do not make actual calls to external REST APIs, which can be unreliable and slow, it is best to mock these invocations. Mocking allows you to simulate the behavior of the external API and provide predefined responses.

Achieving Test Coverage:

By mocking the REST API invocations in your MUnit tests, you can focus on testing the logic within the Mule application itself. This ensures high test coverage and isolates your tests from external dependencies.

Execution of MUnit Tests:

Configure MUnit to return mock responses for the API calls. This enables the MUnit tests to run quickly and consistently, as they are not dependent on the external system's availability or performance.

According to MuleSoft's surveys of global IT leaders, a common cause of IT project failure is a lack of alignment around business outcomes. When IT projects do not have clear business objectives or fail to align with the strategic goals of the organization, they are more likely to face challenges and fail to deliver value. Ensuring that IT initiatives are closely tied to business goals and have stakeholder buy-in is crucial for their success.

Explanation

1 way SSL : The server presents its certificate to the client and the client adds it to its list of trusted certificate. And so, the client can talk to the server.

2-way SSL:  The same principle but both ways. i.e. both the client and the server has to establish trust between themselves using a trusted certificate. In this way of a digital handshake, the server needs to present a certificate to authenticate itself to client and client has to present its certificate to server.

* TLS is a cryptographic protocol that provides communications security for your Mule app.

* TLS offers many different ways of exchanging keys for authentication, encrypting data, and guaranteeing message integrity Keystores and Truststores Truststore and keystore contents differ depending on whether they are used for clients or servers:

For servers: the truststore contains certificates of the trusted clients, the keystore contains the private and public key of the server. For clients: the truststore contains certificates of the trusted servers, the keystore contains the private and public key of the client.

Adding both a keystore and a truststore to the configuration implements two-way TLS authentication also known as mutual authentication.

* in this case, correct answer is Support for TLS mutual (two-way) authentication with HTTP clients.
