  A. When a Mule runtime on a given customer-hosted server is experiencing high memory consumption during certain periods

  B. When an SSL certificate used by one of the deployed Mule applications is about to expire

  C. When the Mute runtime license installed on a Mule runtime is about to expire

  D. When a Mule runtime's customer-hosted server is about to run out of disk space

  Correct Answer: A

  Correct answer is When a Mule runtime on a given customer-hosted server is experiencing high memory consumption during certain periods Using Anypoint Monitoring, you can configure two different types of alerts: Basic alerts for servers and Mule apps Limit per organization: Up to 50 basic alerts for users who do not have a Titanium subscription to Anypoint Platform You can set up basic alerts to trigger email notifications when a metric you are measuring passes a specified threshold. You can create basic alerts for the following metrics for servers or Mule apps: For on-premises servers and CloudHub apps: * CPU utilization * Memory utilization * Thread count Advanced alerts for graphs in custom dashboards in Anypoint Monitoring. You must have a Titanium subscription to use this feature. Limit per organization: Up to 20 advanced alerts

• Question 23:

  A mule application is required to periodically process large data set from a back-end database to Salesforce CRM using batch job scope configured properly process the higher rate of records.

• Question 25:

  Mule application muleA deployed in cloudhub uses Object Store v2 to share data across instances. As a part of new requirement , application muleB which is deployed in same region wants to access this Object Store.

  Which of the following option you would suggest which will have minimum latency in this scenario?

  A. Object Store REST API

  B. Object Store connector

  C. Both of the above option will have same latency

  D. Object Store of one mule application cannot be accessed by other mule application.

  Correct Answer: A

  V2 Rest API is recommended for on premise applications to access Object Store. It also comes with overhead of encryption and security of using rest api. With Object Store v2, the API call is localized to the same data center as the Runtime

  Manager app. But in this case requirement is to access the OS of other mule application and not the same mule application.

  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.

  However, Object Store v2 is not designed for app-to-app communication.

• Question 30:

  A mule application is deployed to a Single Cloudhub worker and the public URL appears in Runtime Manager as the APP URL.

  Requests are sent by external web clients over the public internet to the mule application App url. Each of these requests routed to the HTTPS Listener event source of the running Mule application.

  Later, the DevOps team edits some properties of this running Mule application in Runtime Manager.

  Immediately after the new property values are applied in runtime manager, how is the current Mule application deployment affected and how will future web client requests to the Mule application be handled?

  A. Cloudhub will redeploy the Mule application to the OLD Cloudhub worker New web client requests will RETURN AN ERROR until the Mule application is redeployed to the OLD Cloudhub worker

  B. CloudHub will redeploy the Mule application to a NEW Cloudhub worker New web client requests will RETURN AN ERROR until the NEW Cloudhub worker is available

  C. Cloudhub will redeploy the Mule application to a NEW Cloudhub worker New web client requests are ROUTED to the OLD Cloudhub worker until the NEW Cloudhub worker is available.

  D. Cloudhub will redeploy the mule application to the OLD Cloudhub worker New web client requests are ROUTED to the OLD Cloudhub worker BOTH before and after the Mule application is redeployed.

  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.
