Question 1

Which layer in the API-led connectivity focuses on unlocking key systems, legacy systems, data sources etc and exposes the functionality?

Options:

A.

Experience Layer

B.

Process Layer

C.

System Layer

Question 2

A set of tests must be performed prior to deploying API implementations to a staging environment. Due to data security and access restrictions, untested APIs cannot be granted access to the backend systems, so instead mocked data must be used for these tests. The amount of available mocked data and its contents is sufficient to entirely test the API implementations with no active connections to the backend systems. What type of tests should be used to incorporate this mocked data?

Options:

A.

Integration tests

B.

Performance tests

C.

Functional tests (Blackbox)

D.

Unit tests (Whitebox)

Question 3

What are the major benefits of MuleSoft proposed IT Operating Model?

Options:

A.

1. Decrease the IT delivery gap

2. Meet various business demands without increasing the IT capacity

3. Focus on creation of reusable assets first. Upon finishing creation of all the possible assets then inform the LOBs in the organization to start using them

B.

1. Decrease the IT delivery gap

2. Meet various business demands by increasing the IT capacity and forming various IT departments

3. Make consumption of assets at the rate of production

C.

1. Decrease the IT delivery gap

2. Meet various business demands without increasing the IT capacity

3. Make consumption of assets at the rate of production

Question 4

Once an API Implementation is ready and the API is registered on API Manager, who should request the access to the API on Anypoint Exchange?

Options:

A.

None

B.

Both

C.

API Client

D.

API Consumer

Question 5

A company has created a successful enterprise data model (EDM). The company is committed to building an application network by adopting modern APIs as a core enabler of the company's IT operating model. At what API tiers (experience, process, system) should the company require reusing the EDM when designing modern API data models?

Options:

A.

At the experience and process tiers

B.

At the experience and system tiers

C.

At the process and system tiers

D.

At the experience, process, and system tiers

Question 6

A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity.

The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms.

If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?

Options:

A.

Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries

B.

Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete

C.

No timeout is possible to meet the upstream API's desired SLA; a different SLA must be negotiated with the first downstream API or invoke an alternative API

D.

Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds

Question 7

Refer to the exhibit.

Three business processes need to be implemented, and the implementations need to communicate with several different SaaS applications.

These processes are owned by separate (siloed) LOBs and are mainly independent of each other, but do share a few business entities. Each LOB has one development team and their own budget

In this organizational context, what is the most effective approach to choose the API data models for the APIs that will implement these business processes with minimal redundancy of the data models?

A) Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities

B) Build distinct data models for each API to follow established micro-services and Agile API-centric practices

C) Build all API data models using XML schema to drive consistency and reuse across the organization

D) Build one centralized Canonical Data Model (Enterprise Data Model) that unifies all the data types from all three business processes, ensuring the data model is consistent and non-redundant

Options:

A.

Option A

B.

Option B

C.

Option C

D.

Option D

Question 8

What is true about where an API policy is defined in Anypoint Platform and how it is then applied to API instances?

Options:

A.

The API policy Is defined In Runtime Manager as part of the API deployment to a Mule runtime, and then ONLY applied to the specific API Instance

B.

The API policy Is defined In API Manager for a specific API Instance, and then ONLY applied to the specific API instance

C.

The API policy Is defined in API Manager and then automatically applied to ALL API instances

D.

The API policy is defined in API Manager, and then applied to ALL API instances in the specified environment

Question 9

Refer to the exhibit.

An organization uses one specific CloudHub (AWS) region for all CloudHub deployments.

How are CloudHub workers assigned to availability zones (AZs) when the organization's Mule applications are deployed to CloudHub in that region?

Options:

A.

Workers belonging to a given environment are assigned to the same AZ within that region

B.

AZs are selected as part of the Mule application's deployment configuration

C.

Workers are randomly distributed across available AZs within that region

D.

An AZ is randomly selected for a Mule application, and all the Mule application's CloudHub workers are assigned to that one AZ

Question 10

In which layer of API-led connectivity, does the business logic orchestration reside?

Options:

A.

System Layer

B.

Experience Layer

C.

Process Layer

Question 11

A) Java RMI over TCP

B) Java RMI over TCP

C) CORBA over HOP

D) XML over UDP

Options:

A.

Option A

B.

Option B

C.

Option C

D.

Option D

Question 12

When using CloudHub with the Shared Load Balancer, what is managed EXCLUSIVELY by the API implementation (the Mule application) and NOT by Anypoint Platform?

Options:

A.

The assignment of each HTTP request to a particular CloudHub worker

B.

The logging configuration that enables log entries to be visible in Runtime Manager

C.

The SSL certificates used by the API implementation to expose HTTPS endpoints

D.

The number of DNS entries allocated to the API implementation
