Question 1

A Mule application uses the Database connector.
What condition can the Mule application automatically adjust to or recover from without needing to restart or redeploy the Mule application?

One of the stored procedures being called by the Mule application has been renamed

The database server has been updated and hence the database driver library/JAR needs a minor version upgrade

The database server was unavailable for four hours due to a major outage but is now fully operational again

The credentials for accessing the database have been updated and the previous credentials are no longer valid

Question 2

Refer to the exhibit.
MCIA-Level-1 dumps exhibit

A Mule application is deployed to a cluster of two customer-hosted Mute runtimes. The Mute application has a flow that polls a database and another flow with an HTTP Listener.
HTTP clients send HTTP requests directly to individual cluster nodes.
What happens to database polling and HTTP request handling in the time after the primary (master) node of the cluster has railed, but before that node is restarted?

Database polling continues Only HTTP requests sent to the remaining node continue to be accepted

Database polling stops All HTTP requests continue to be accepted

Database polling continues All HTTP requests continue to be accepted, but requests to the failed node Incur increased latency

Database polling stops All HTTP requests are rejected

Question 3

An organization is designing the following two Mule applications that must share data via a common persistent object store instance:
- Mule application P will be deployed within their on-premises datacenter. - Mule application C will run on CloudHub in an Anypoint VPC.
The object store implementation used by CloudHub is the Anypoint Object Store v2 (OSv2).
What type of object store(s) should be used, and what design gives both Mule applications access to the same object store instance?

Application C and P both use the Object Store connector to access the Anypoint Object Store v2

Application C and P both use the Object Store connector to access a persistent object store

Application C uses the Object Store connector to access a persistent objectApplication P accesses the persistent object store via the Object Store REST API

Application P uses the Object Store connector to access a persistent object storeApplication C accesses this persistent object store via the Object Store REST API through an IPsec tunnel

Question 4

Anypoint Exchange is required to maintain the source code of some of the assets committed to it, such as Connectors, Templates, and API specifications.
What is the best way to use an organization's source-code management (SCM) system in this context?

Organizations should continue to use an SCM system of their choice, in addition to keeping source codefor these asset types in Anypoint Exchange, thereby enabling parallel development, branching, and merging

Organizations need to use Anypoint Exchange as the main SCM system to centralize versioning and avoid code duplication

Organizations can continue to use an SCM system of their choice for branching and merging, as long as they follow the branching and merging strategy enforced by Anypoint Exchange

Organizations need to point Anypoint Exchange to their SCM system so Anypoint Exchange can pull source code when requested by developers and provide it to Anypoint Studio

Question 5

A Mule application contains a Batch Job with two Batch Steps (Batch_Step_1 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?

Each Batch Job uses SEVERAL THREADS for the Batch StepsEach 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

Each Batch Job uses SEVERAL THREADS for the Batch StepsEach 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

Each Batch Job uses a SINGLE THREAD for all Batch StepsEach Batch Step instance receives ONE record at a time as the payload, and RECORDS are processed IN ORDER, first through Batch_Step_1 and then through Batch_Step_2

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

Question 6

An integration Mule application consumes and processes a list of rows from a CSV file. Each row must be read from the CSV file, validated, and the row data sent to a JMS queue, in the exact order as in the CSV file.
If any processing step for a row fails, then a log entry must be written for that row, but processing of other rows must not be affected.
What combination of Mule components is most idiomatic (used according to their intended purpose) when implementing the above requirements?

Scatter-Gather componentOn Error Continue scope

VM connectorFirst Successful scopeOn Error Propagate scope

Async scopeOn Error Propagate scope

For Each scopeOn Error Continue scope

Question 7

A Mule application currently writes to two separate SQL Server database instances across the internet using a single XA transaction. It is proposed to split this one transaction into two separate non-XA transactions with no other changes to the Mule application.
What non-functional requirement can be expected to be negatively affected when implementing this change?

Throughput

Availability

Response time

Consistency

Question 8

An organization is creating a set of new services that are critical for their business. The project team prefers using REST for all services but is willing to use SOAP with common WS-* standards if a particular service requires it.
What requirement would drive the team to use SOAP/WS-* for a particular service?

Must secure the service, requiring all consumers to submit a valid SAML token

Must support message acknowledgement and retry as part of the protocol

Must publish and share the service specification (including data formats) with the consumers of the service

Must use XML payloads for the service and ensure that it adheres to a specific schema

Question 9

What limits if a particular Anypoint Platform user can discover an asset in Anypoint Exchange?

The type of the asset in Anypoint Exchange

The business groups to which the user belongs

If Design Center and RAML were both used to create the asset

The existence of a public Anypoint Exchange portal to which the asset has been published

Question 10

Refer to the exhibit.
MCIA-Level-1 dumps exhibit

A Mule application is deployed to a multi-node Mule runtime cluster. The Mule application uses the competing consumer pattern among its cluster replicas to receive JMS messages from a JMS queue. To process each received JMS message, the following steps are performed in a flow:
Step l: The JMS Correlation ID header is read from the received JMS message.
Step 2: The Mule application invokes an idempotent SOAP webservice over HTTPS, passing the JMS Correlation ID as one parameter in the SOAP request.
Step 3: The response from the SOAP webservice also returns the same JMS Correlation ID.
Step 4: The JMS Correlation ID received from the SOAP webservice is validated to be identical to the JMS Correlation ID received in Step 1.
Step 5: The Mule application creates a response JMS message, setting the JMS Correlation ID message header to the validated JMS Correlation ID and publishes that message to a response JMS queue.
Where should the Mule application store the JMS Correlation ID values received in Step 1 and Step 3 so that the validation in Step 4 can be performed, while also making the overall Mule application highly available, fault-tolerant, performant, and maintainable?

Both Correlation ID values should be stored in a persistent object store

Both Correlation ID values should be stored In a non-persistent object store

The Correlation ID value in Step 1 should be stored in a persistent object storeThe Correlation ID value in step 3 should be stored as a Mule event vanable/attnbute

Both Correlation ID values should be stored as Mule event vanabtes/attnbutes

Question 11

What is true about the network connections when a Mule application uses a JMS connector to interact with a JMS provider (message broker)?

The JMS connector supports both sending and receiving of JMS messages over the protocol determined by the JMS provider

The AMQP protocol can be used by the JMS connector to portably establish connections to various types of JMS providers

To receive messages into the Mule application, the JMS provider initiates a network connection to the JMS connector and pushes messages along this connection

To complete sending a JMS message, the JMS connector must establish a network connection with the JMS message recipient

Question 12

Mule applications need to be deployed to CloudHub so they can access on-premises database
systems. These systems store sensitive and hence tightly protected data, so are not accessible over
the internet.
What network architecture supports this requirement?

An Anypoint VPC connected to the on-premises network using an IPsec tunnel or AWSDirectConnect, plus matching firewall rulesin the VPC and on-premises network

Static IP addresses for the Mule applications deployed to the CloudHub Shared Worker Cloud, plusmatching firewall rules and IPwhitelisting in the on-premises network

An Anypoint VPC with one Dedicated Load Balancer fronting each on-premises database system,plus matching IP whitelisting in the load balancer and firewall rules in the VPC and on-premisesnetwork

Relocation of the database systems to a DMZ in the on-premises network, with Mule applicationsdeployed to the CloudHub Shared Worker Cloud connecting only to the DMZ

Question 13

An organization's security policies mandate complete control of the login credentials used to log in to Anypoint Platform. What feature of Anypoint Platform should be used to meet this requirement?

Enterprise Security Module

Client ID Secret

Federated Identity Management

The Mule runtimes

Question 15

An organization has various integrations implemented as Mule applications. Some of these Mule applications are deployed to customhosted Mule runtimes (on-premises) while others execute in theMuleSoft-hosted runtime plane (CloudHub). To perform the Integra functionality, these Mule applications connect to various backend systems, with multiple applications typically needing to access the backend systems.
How can the organization most effectively avoid creating duplicates in each Mule application of the credentials required to access thebackend systems?

Create a Mule domain project that maintains the credentials as Mule domain-shared resources Deploy the Mule applications to the Mule domain, so the credentials are available to the Mule applications

Store the credentials in properties files in a shared folder within the organization's data center Have the Mule applications load properties files from this shared location at startup

Segregate the credentials for each backend system into environment-specific properties files Package these properties files in each Mule application, from where they are loaded at startup

Configure or create a credentials service that returns the credentials for each backend system, and that is accessible from customer-hosted and MuleSoft-hosted Mule runtimes Have the Mule applications toad the properties at startup by invoking that credentials service

Question 16

What aspect of logging is only possible for Mule applications deployed to customer-hosted Mule runtimes, but NOT for Mule applications deployed to CloudHub?

To send Mule application log entries to Splunk

To change tog4j2 tog levels in Anypoint Runtime Manager without having to restart the Mule application

To log certain messages to a custom log category

To directly referenceone shared and customized log4j2.xml file from multiple Mule applications

Question 17

An organization's governance process requires project teams to get formal approval from all key stakeholders for all new Integration design specifications. An integration Mule application Is being designed that interacts with various backend systems. The Mule application will be created using Anypoint Design Center or Anypoint Studio and will then be deployed to a customer-hosted runtime.
What key elements should be included in the integration design specification when requesting approval for this Mule application?

SLAs and non-functional requirements to access the backend systems

Snapshots of the Mule application's flows, including their error handling

A list of current and future consumers of the Mule application and their contact details

The credentials to access the backend systems and contact details for the administrator of each system

Question 18

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?

API-led connectivity

Batch-triggered ETL

Event-driven architecture

Microservice architecture

Question 19

Refer to the exhibit.

A watermark will be used to only retrieve those Satesforce Accounts that have been modified since the last time the integration logic ran.
What is the most appropriate way to implement persistence for the watermark in order to support the required data replication integration logic?

Persistent Anypoint MQ Queue

Persistent Object Store

Persistent Cache Scope

Persistent VM Queue

Question 21

Refer to the exhibit.
MCIA-Level-1 dumps exhibit

Anypoint Platform supports role-based access control (RBAC) to features of the platform. An organization has configured an external Identity Provider for identity management with Anypoint Platform.
What aspects of RBAC must ALWAYS be controlled from the Anypoint Platform control plane and CANNOT be controlled via the external Identity Provider?

Controlling the business group within Anypoint Platform to which the user belongs

Assigning Anypoint Platform permissions to a role

Assigning Anypoint Platform role(s) to a user

Removing a user's access to Anypoint Platform when they no longer work for the organization

Question 22

Refer to the exhibit. A business process involves two APIs that interact with each other asynchronously over HTTP.
Each API is implemented as a Mule application. API 1 receives the initial HTTP request and invokes API 2 (in a fire and forget fashion) while API 2, upon completion of the processing, calls back into API 1 to notify about completion of the asynchronous process.
Each API is deployed to multiple redundant Mule runtimes and a separate load balancer, and is deployed to a separate network zone. In the network architecture, how must the firewall rules be configured to enable the above interaction between API 1 and API 2?
MCIA-Level-1 dumps exhibit

To allow communication between the load balancers used by each API

To authorize the certificates used by both the APIs

To open direct two-way communication between the Mule runtimes of both APIs

To enable communication from each API\\'s Mule runtimes and network zone to the load balancer of the other API
