Question 1

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?

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

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

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

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

Answer : D

Question 2

Refer to the exhibit.

The HTTP Listener and the Logger are being handled from which thread pools respectively?

ACPU_INTENSIVE and Dedicated Selector pool

BUBER and NONBLOCKING

CShared Selector Pool and CPU LITE

DBLOCKING _IO and UBER

Answer : C

Question 3

A stock broking company makes use of CloudHub VPC to deploy Mule applications. Mule application needs to connect to a database application in the customers on-premises corporate data center and also to a Kafka cluster running in AWS VPC.

How is access enabled for the API to connect to the database application and Kafka cluster securely?

ASet up a transit gateway to the customers on-premises corporate datacenter to AWS VPC

BSetup AnyPoint VPN to the customer's on-premise corporate data
center and VPC peering with AWS VPC

CSetup VPC peering with AWS VPC and the customers devices corporate data center

DSetup VPC peering with the customers onto my service corporate data center and Anypoint VPN to AWS VPC

Answer : B

Question 4

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?

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

BWhen 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.

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

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

Answer : C

Object Store Connector is a Mule component that allows for simple key-value storage. Although it can serve a wide variety of use cases, it is mainly design for: - Storing synchronization information, such as watermarks. - Storing temporal information such as access tokens. - Storing user information. Additionally, Mule Runtime uses Object Stores to support some of its own components, for example: - The Cache module uses an Object Store to maintain all of the cached data. - The OAuth module (and every OAuth enabled connector) uses Object Stores to store the access and refresh tokens. Object Store data is in the same region as the worker where the app is initially deployed. For example, if you deploy to the Singapore region, the object store persists in the Singapore region. MuleSoft Reference : https://docs.mulesoft.com/object-store-connector/1.1/ Data can be shared between different instances of the Mule application. This is not recommended for Inter Mule app communication. Coming to the question, object store cannot be used to share cached data if it is deployed as separate Mule applications or deployed under separate Business Groups. Hence correct answer is When there is one CloudHub deployment of the API implementation to three workers that must share the cache state.

Question 5

A REST API is being designed to implement a Mule application.

What standard interface definition language can be used to define REST APIs?

AWeb Service Definition Language(WSDL)

BOpenAPI Specification (OAS)

CYAML

DAsyncAPI Specification

Answer : B

Question 6

According to MuteSoft, which principle is common to both Service Oriented Architecture (SOA) and API-led connectivity approaches?

AService centralization

BService statefulness

CService reusability

DService interdependence

Answer : C

Question 7

A Mule application contains a Batch Job with two Batch Steps (Batch_Step_l and Batch_Step_2). A payload with 1000 records is received by the Batch Job.

How many threads are used by the Batch Job to process records, and how does each Batch Step process records within the Batch Job?

AEach Batch Job uses SEVERAL THREADS for the Batch Steps Each Batch Step instance receives ONE record at a time as the payload, and RECORDS are processed IN PARALLEL within and between the two Batch Steps

BEach Batch Job uses a SINGLE THREAD for all Batch steps Each Batch step instance receives ONE record at a time as the payload, and RECORDS are processed IN ORDER, first through Batch_Step_l and then through Batch_Step_2

CEach Batch Job uses a SINGLE THREAD to process a configured block size of record Each Batch Step instance receives A BLOCK OF records as the payload, and BLOCKS of records are processed IN ORDER

DEach Batch Job uses SEVERAL THREADS for the Batch Steps Each Batch Step instance receives ONE record at a time as the payload, and BATCH STEP INSTANCES execute IN PARALLEL to process records and Batch Steps in ANY order as fast as possible

Answer : A

*Each Batch Job uses SEVERAL THREADS for the Batch Steps

*Each Batch Step instance receives ONE record at a time as the payload. It's not received in a block, as it does not wait for multiple records to be completed before moving to next batch step. (So Option D is out of choice)

*RECORDS are processed IN PARALLEL within and between the two Batch Steps.

*RECORDSare not processed in order. Let's say if second record completes batch_step_1 before record 1, then it moves to batch_step_2 before record 1. (So option C and D are out of choice)

*A batch job is the scope element in an application in which Mule processes a message payload as a batch of records. The term batch job is inclusive of all three phases of processing: Load and Dispatch, Process, and On Complete.

*A batch job instance is an occurrence in a Mule application whenever a Mule flow executes a batch job. Mule creates the batch job instance in the Load and Dispatch phase. Every batch job instance is identified internally using a unique String known as batchjob instance id.
