Questions # 21:

An insurance provider is implementing Anypoint platform to manage its application infrastructure and is using the customer hosted runtime for its business due to certain financial requirements it must meet. It has built a number of synchronous API's and is currently hosting these on a mule runtime on one server

These applications make use of a number of components including heavy use of object stores and VM queues.

Business has grown rapidly in the last year and the insurance provider is starting to receive reports of reliability issues from its applications.

The DevOps team indicates that the API's are currently handling too many requests and this is over loading the server. The team has also mentioned that there is a significant downtime when the server is down for maintenance.

As an integration architect, which option would you suggest to mitigate these issues?

Options:

A.

Add a load balancer and add additional servers in a server group configuration


B.

Add a load balancer and add additional servers in a cluster configuration


C.

Increase physical specifications of server CPU memory and network


D.

Change applications by use an event-driven model

Questions # 22:

A corporation has deployed multiple mule applications implementing various public and private API's to different cloudhub workers. These API's arc Critical applications that must be highly available and in line with the reliability SLA as defined by stakeholders.

How can API availability (liveliness or readiness) be monitored so that Ops team receives outage notifications?

Options:

A.

Enable monitoring of individual applications from Anypoint monitoring


B.

Configure alerts with failure conditions in runtime manager


C.

Configure alerts failure conditions in API manager


D.

Use any point functional monitoring test API's functional behavior


Expert Solution
Questions # 23:

A mule application uses an HTTP request operation to involve an external API.

The external API follows the HTTP specification for proper status code usage.

What is possible cause when a 3xx status code is returned to the HTTP Request operation from the external API?

Options:

A.

The request was not accepted by the external API


B.

The request was Redirected to a different URL by the external API


C.

The request was NOT RECEIVED by the external API


D.

The request was ACCEPTED by the external API

Questions # 24:

An organization has implemented a continuous integration (CI) lifecycle that promotes Mule applications through code, build, and test stages. To standardize the organization's CI journey, a new dependency control approach is being designed to store artifacts that include information such as dependencies, versioning, and build promotions.

To implement these process improvements, the organization will now require developers to maintain all dependencies related to Mule application code in a shared location.

What is the most idiomatic (used for its intended purpose) type of system the organization should use in a shared location to standardize all dependencies related to Mule application code?

Options:

A.

A MuleSoft-managed repository atrepository.mulesoft.org


B.

A binary artifact repository


C.

API Community Manager


D.

The Anypoint Object Store service at cloudhub.io

Questions # 25:

What is a key difference between synchronous and asynchronous logging from Mule applications?

Options:

A.

Synchronous logging writes log messages in a single logging thread but does not block the Mule event being processed by the next event processor


B.

Asynchronous logging can improve Mule event processing throughput while also reducing the processing time for each Mule event


C.

Asynchronous logging produces more reliable audit trails with more accurate timestamps


D.

Synchronous logging within an ongoing transaction writes log messages in the same thread that processes the current Mule event


Expert Solution
Questions # 26:

An organization has deployed runtime fabric on an eight note cluster with performance profile. An API uses and non persistent object store for maintaining some of its state data. What will be the impact to the stale data if server crashes?

Options:

A.

State data is preserved


B.

State data is rolled back to a previously saved version


C.

State data is lost


D.

State data is preserved as long as more than one more is unaffected by the crash


Expert Solution
Questions # 27:

An organization has deployed both Mule and non-Mule API implementations to integrate its customer and order management systems. All the APIs are available to REST clients on the public internet.

The organization wants to monitor these APIs by running health checks: for example, to determine if an API can properly accept and process requests. The organization does not have subscriptions to any external monitoring tools and also does not want to extend its IT footprint.

What Anypoint Platform feature provides the most idiomatic (used for its intended purpose) way to monitor the availability of both the Mule and the non-Mule API implementations?

Options:

A.

API Functional Monitoring


B.

Runtime Manager


C.

API Manager


D.

Anypoint Visualizer

Questions # 28:

A project team uses RAML specifications to document API functional requirements and deliver API definitions. As per the current legal requirement, all designed API definitions to be augmented with an additional non-functional requirement to protect the services from a high rate of requests according to define service level agreements.

Assuming that the project is following Mulesoft API governance and policies, how should the project team convey the necessary non-functional requirement to stakeholders?

Options:

A.

Create proxies in API manager for the non functional requirement and publish to exchange


B.

Add all non functional requirements as comments to RAML specification and publish to exchange


C.

Create various SLA's in API manager for the non functional requirement and publish to exchange


D.

Update API definitions with the fragment for the appropriate policy and publish to exchange


Expert Solution
Questions # 29:

As an enterprise architect, what are the two reasons for which you would use a canonical data model in the new integration project using Mulesoft Anypoint platform ( choose two answers )

Options:

A.

To have consistent data structure aligned in processes


B.

To isolate areas within a bounded context


C.

To incorporate industry standard data formats


D.

There are multiple canonical definitions of each data type


E.

Because the model isolates the back and systems and support mule applications from change


Expert Solution
Questions # 30:

A Mule application is synchronizing customer data between two different database systems.

What is the main benefit of using eXtended Architecture (XA) transactions over local transactions to synchronize these two different database systems?

Options:

A.

An XA transaction synchronizes the database systems with the least amount of Mule configuration or coding


B.

An XA transaction handles the largest number of requests in the shortest time


C.

An XA transaction automatically rolls back operations against both database systems if any operation falls


D.

An XA transaction writes to both database systems as fast as possible
