MCPA-Level-1 MuleSoft Certified Platform Architect - Level 1 Questions and Answers

Questions 4

An API experiences a high rate of client requests (TPS) vwth small message paytoads. How can usage limits be imposed on the API based on the type of client application?

Options:

A.

Use an SLA-based rate limiting policy and assign a client application to a matching SLA tier based on its type

B.

Use a spike control policy that limits the number of requests for each client application type

C.

Use a cross-origin resource sharing (CORS) policy to limit resource sharing between client applications, configured by the client application type

D.

Use a rate limiting policy and a client ID enforcement policy, each configured by the client application type

An organization has created an API-led architecture that uses various API layers to integrate mobile clients with a backend system. The backend system consists of a number of specialized components and can be accessed via a REST API. The process and experience APIs share the same bounded-context model that is different from the backend data model. What additional canonical models, bounded-context models, or anti-corruption layers are best added to this architecture to help process data consumed from the backend system?

Options:

A.

Create a bounded-context model for every layer and overlap them when the boundary contexts overlap, letting API developers know about the differences between upstream and downstream data models

B.

Create a canonical model that combines the backend and API-led models to simplify and unify data models, and minimize data transformations.

C.

Create a bounded-context model for the system layer to closely match the backend data model, and add an anti-corruption layer to let the different bounded contexts cooperate across the system and process layers

D.

Create an anti-corruption layer for every API to perform transformation for every data model to match each other, and let data simply travel between APIs to avoid the complexity and overhead of building canonical models

Refer to the exhibit.

what is true when using customer-hosted Mule runtimes with the MuleSoft-hosted Anypoint Platform control plane (hybrid deployment)?

Options:

A.

Anypoint Runtime Manager initiates a network connection to a Mule runtime in order to deploy Mule applications

B.

The MuleSoft-hosted Shared Load Balancer can be used to load balance API invocations to the Mule runtimes

C.

API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane

D.

Anypoint Runtime Manager automatically ensures HA in the control plane by creating a new Mule runtime instance in case of a node failure

An API implementation is deployed on a single worker on CloudHub and invoked by external API clients (outside of CloudHub). How can an alert be set up that is guaranteed to trigger AS SOON AS that API implementation stops responding to API invocations?

Options:

A.

Implement a heartbeat/health check within the API and invoke it from outside the Anypoint Platform and alert when the heartbeat does not respond

B.

Configure a "worker not responding" alert in Anypoint Runtime Manager

C.

Handle API invocation exceptions within the calling API client and raise an alert from that API client when the API Is unavailable

D.

Create an alert for when the API receives no requests within a specified time period

A system API has a guaranteed SLA of 100 ms per request. The system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. An upstream process API invokes the system API and the main goal of this process API is to respond to client requests in the least possible time. In what order should the system APIs be invoked, and what changes should be made in order to speed up the response time for requests from the process API?

Options:

A.

In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment, and ONLY use the first response

B.

In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment using a scatter-gather configured with a timeout, and then merge the responses

C.

Invoke the system API deployed to the primary environment, and if it fails, invoke the system API deployed to the DR environment

D.

Invoke ONLY the system API deployed to the primary environment, and add timeout and retry logic to avoid intermittent failures

B.

The credentials provided by the IdP for client management

C.

An OAuth 2.0 token generated using the credentials provided by the IdP for client management

B.

Measurements of the effectiveness of the application network based on the level of reuse

C.

Data on past API invocations to help identify anomalies and usage patterns across various APIs

D.

Proactive identification of likely future policy violations that exceed a given threat threshold

Options:

A.

At the API proxy

B.

At the API implementation

C.

At both the API proxy and the API implementation

D.

At a MuleSoft-hosted load balancer
