Question 1

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 2

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 3

An organization is designing an integration solution to replicate financial transaction data from a legacy system into a data warehouse (DWH).

The DWH must contain a daily snapshot of financial transactions, to be delivered as a CSV file. Daily transaction volume exceeds tens of millions of records, with significant spikes in volume during popular shopping periods.

What is the most appropriate integration style for an integration solution that meets the organization's current requirements?

AEvent-driven architecture

BMicroservice architecture

CAPI-led connectivity

DBatch-triggered ETL

Answer : D

Correct answer is Batch-triggered ETL Within a Mule application, batch processing provides a construct for asynchronously processing larger-than-memory data sets that are split into individual records. Batch jobs allow for the description of a reliable process that automatically splits up source data and stores it into persistent queues, which makes it possible to process large data sets while providing reliability. In the event that the application is redeployed or Mule crashes, the job execution is able to resume at the point it stopped.

Question 4

According to MuleSoft, which system integration term describes the method, format, and protocol used for communication between two system?

AComponent

Binteraction

CMessage

DInterface

Answer : D

Question 5

Organization wants to achieve high availability goal for Mule applications in customer hosted runtime plane. Due to the complexity involved, data cannot be shared among of different instances of same Mule application. What option best suits to this requirement considering high availability is very much critical to the organization?

AThe cluster can be configured

BUse third party product to implement load balancer

CHigh availability can be achieved only in CloudHub

DUse persistent object store

Answer : B

High availability is about up-time of your application

A) High availability can be achieved only in CloudHub isn't correct statement. It can be achieved in customer hosted runtime planes as well

B) An object store is a facility for storing objects in or across Mule applications. Mule runtime engine (Mule) uses object stores to persist data for eventual retrieval. It can be used for disaster recovery but not for High Availability. Using object store can't guarantee that all instances won't go down at once. So not an appropriate choice.

C) High availability can be achieved by below two models for on-premise MuleSoft implementations.

1) Mule Clustering -- Where multiple Mule servers are available within the same cluster environment and the routing of requests will be done by the load balancer. A cluster is a set of up to eight servers that act as a single deployment target and high-availability processing unit. Application instances in a cluster are aware of each other, share common information, and synchronize statuses. If one server fails, another server takes over processing applications. A cluster can run multiple applications. ( refer left half of the diagram)

In given scenario, it's mentioned that 'data cannot be shared among of different instances'. So this is not a correct choice.

2) Load balanced standalone Mule instances -- The high availability can be achieved even without cluster, with the usage of third party load balancer pointing requests to different Mule servers. This approach does not share or synchronize data between Mule runtimes. Also high availability achieved as load balanced algorithms can be implemented using external load balancer. ( refer right half of the diagram)

Question 6

An insurance company has an existing API which is currently used by customers. API is deployed to customer hosted Mule runtime cluster. The load balancer that is used to access any APIs on the mule cluster is only configured to point to applications hosted on the server at port 443.

Mule application team of a company attempted to deploy a second API using port 443 but the application will not start and checking logs shows an error indicating the address is already in use.

Which steps must the organization take to resolve this error and allow customers to access both the API's?

AChange the base path of the HTTP listener configuration in the second API to a different one from the first API

BSet HTTP listener configuration in both API's to allow for connections from multiple ports

CMove the HTTP listener configurations from the API's and package them in a mule domain project using port 443

DSet the HTTP listener of the second API to use different port than the one used in the first API

Answer : C

Question 7

Refer to the exhibit.

An organization uses a 2-node Mute runtime cluster to host one stateless API implementation. The API is accessed over HTTPS through a load balancer that uses round-robin for load distribution.

Two additional nodes have been added to the cluster and the load balancer has been configured to recognize the new nodes with no other change to the load balancer.

What average performance change is guaranteed to happen, assuming all cluster nodes are fully operational?

A50% reduction in the response time of the API

B100% increase in the throughput of the API

C50% reduction In the JVM heap memory consumed by each node

D50% reduction In the number of requests being received by each node

Answer : D
