MCIA-LEVEL-1-MAINTENANCE Online Practice Questions and Answers

Correct Answer: A

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.

Correct Answer: B

Correct answer is Untill Successful scope can be implemented while calling backend API's The Until Successful scope repeatedly triggers the scope's components (including flow references) until they all succeed or until a maximum number of retries is exceeded The scope provides option to control the max number of retries and the interval between retries The scope can execute any sequence of processors that may fail for whatever reason and may succeed upon retry

Correct Answer: C

Correct Answer: C

CloudHub supports updating your applications at runtime so end users of your HTTP APIs experience zero downtime. While your application update is deploying, CloudHub keeps the old version of your application running. Your domain points to the old version of your application until the newly uploaded version is fully started. This allows you to keep servicing requests from your old application while the new version of your application is starting.

Correct Answer: D

Sharing Mule applications as templates is a great way to share your work with other people who are in your organization in Anypoint Platform. When they need to build a similar application they can create the mule application using the

template project from Anypoint studio.

*

Anypoint Templates are designed to make it easier and faster to go from a blank canvas to a production application. They're bit for bit Mule applications requiring only Anypoint Studio to build and design, and are deployable both on-

premises and in the cloud.

*

Anypoint Templates are based on five common data Integration patterns and can be customized and extended to fit your integration needs. So even if your use case involves different endpoints or connectors than those included in the

template, they still offer a great starting point.

Some of the best practices while creating the template project:

-

Define the common error handler as part of template project, either using pom dependency or mule config file

-

Define common logger/audit framework as part of the template project

-

Define the env specific properties and secure properties file as per the requirement

-Define global.xml for global configuration

-

Define the config file for connector configuration like Http,Salesforce,File,FTP etc

-

Create separate folders to create DWL,Properties,SSL certificates etc

-

Add the dependency and configure the pom.xml as per the business need

-Configure the mule-artifact.json as per the business need

Correct Answer: D

Correct Answer: B

Correct Answer: C

Correct answer is Request size, number of requests, response size, response time Analytics API Analytics can provide insight into how your APIs are being used and how they are performing. From API Manager, you can access the Analytics dashboard, create a custom dashboard, create and manage charts, and create reports. From API Manager, you can get following types of analytics: - API viewing analytics - API events analytics - Charted metrics in API Manager It can be accessed using: http://anypoint.mulesoft.com/analytics API Analytics provides a summary in chart form of requests, top apps, and latency for a particular duration. The custom dashboard in Anypoint Analytics contains a set of charts for a single API or for all APIs Each chart displays various API characteristics ?Requests size: Line chart representing size of requests in KBs ?Requests : Line chart representing number of requests over a period ?Response size : Line chart representing size of response in KBs ?Response time :Line chart representing response time in ms

* To check this, You can go to API Manager > Analytics > Custom Dashboard > Edit Dashboard > Create Chart > Metric

Reference: https://docs.mulesoft.com/monitoring/api-analytics-dashboard

Additional Information:

The default dashboard contains a set of charts Requests by date: Line chart representing number of requests Requests by location: Map chart showing the number of requests for each country of origin Requests by application: Bar chart showing the number of requests from each of the top five registered applications Requests by platform: Ring chart showing the number of requests broken down by platform

Correct Answer: D

The mocking service is a feature of Anypoint Platform and runs continuously. You can run the mocking service from the text editor, the visual editor, and from Anypoint Exchange. You can simulate calls to the API in API Designer before publishing the API specification to Exchange or in Exchange after publishing the API specification.
