An organization has strict unit test requirement that mandate every mule application must have an MUnit test suit with a test case defined for each flow and a minimum test coverage of 80%.

A developer is building Munit test suit for a newly developed mule application that sends API request to an external rest API.

What is the effective approach for successfully executing the Munit tests of this new application while still achieving the required test coverage for the Munit tests?

A. Invoke the external endpoint of the rest API from the mule floors

B. Mark the rest API invocations in the Munits and then call the mocking service flow that simulates standard responses from the REST API

C. Mock the rest API invocation in the Munits and return a mock response for those invocations

D. Create a mocking service flow to simulate standard responses from the rest API and then configure the mule flows to call the marking service flow

An organization is choosing between API-led connectivity and other integration approaches.

According to MuleSoft, which business benefits is associated with an API-led connectivity approach using Anypoint Platform?

A. improved security through adoption of monolithic architectures

B. Increased developer productivity through sell-service of API assets

C. Greater project predictability through tight coupling of systems

D. Higher outcome repeatability through centralized development

An organization is implementing a Quote of the Day API that caches today's quote. What scenario can use the CloudHub Object Store connector to persist the cache's state?

A. When there is one deployment of the API implementation to CloudHub and another one to customer hosted mule runtime that must share the cache state.

B. When there are two CloudHub deployments of the API implementation by two Anypoint Platform business groups to the same CloudHub region that must share the cache state.

C. When there is one CloudHub deployment of the API implementation to three workers that must share the cache state.

D. When there are three CloudHub deployments of the API implementation to three separate CloudHub regions that must share the cache state.

A platform architect includes both an API gateway and a service mesh in the architect of a distributed application for communication management. Which type of communication management does a service mesh typically perform in this architecture?

A. Between application services and the firewall

B. Between the application and external API clients

C. Between services within the application

D. Between the application and external API implementations.

In Anypoint Platform, a company wants to configure multiple identity providers(Idps) for various lines of business (LOBs) Multiple business groups and environments have been defined for the these LOBs. What Anypoint Platform feature can use multiple Idps access the company's business groups and environment?

A. User management

B. Roles and permissions

C. Dedicated load balancers

D. Client Management

What is a core pillar of the MuleSoft Catalyst delivery approach?

A. Business outcomes

B. Technology centralization

C. Process thinking

D. Scope reduction

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?

A. A MuleSoft-managed repository at repository.mulesoft.org

B. A binary artifact repository

C. API Community Manager

D. The Anypoint Object Store service at cloudhub.io

According to MuleSoft, which deployment characteristic applies to a microservices application architecture?

A. Services exist as independent deployment artifacts and can be scaled -independently of other services

B. All services of an application can be deployed together as single Java WAR file

C. A deployment to enhance one capability requires a redeployment of all capabilities

D. Core business capabilities are encapsulated in a single, deployable application

An organization uses a four(4) node customer hosted Mule runtime cluster to host one(1) stateless api implementation. The API is accessed over HTTPS through a load balancer that uses round-robin for load distribution. Each node in the cluster has been sized to be able to accept four(4) times the current number of requests.

Two(2) nodes in the cluster experience a power outage and are no longer available. The load balancer directs the outage and blocks the two unavailable the nodes from receiving further HTTP requests.

What performance-related consequence is guaranteed to happen to average, assuming the remaining cluster nodes are fully operational?

A. 100% increase in the average response time of the API

B. 50% reduction in the throughput of the API

C. 100% increase in the number of requests received by each remaining node

D. 50% increase in the JVM heap memory consumed by each remaining node

Refer to the exhibit.

An organization is sizing an Anypoint VPC for the non-production deployments of those Mule applications that connect to the organization's on-premises systems. This applies to approx. 60 Mule applications. Each application is deployed to

two CloudHub i workers. The organization currently has three non-production environments (DEV, SIT and UAT) that share this VPC. The AWS region of the VPC has two AZs.

The organization has a very mature DevOps approach which automatically progresses each application through all non-production environments before automatically deploying to production. This process results in several Mule application

deployments per hour, using CloudHub's normal zero-downtime deployment feature.

What is a CIDR block for this VPC that results in the smallest usable private IP address range?

A. 10.0.0.0/26 (64 IPS)

B. 10.0.0.0/25 (128 IPs)

C. 10.0.0.0/24 (256 IPs)

D. 10.0.0.0/22 (1024 IPs)
