Question # 2

An application deployed to a runtime fabric environment with two cluster replicas is designed to periodically trigger of flow for processing a high-volume set of records from the source system and synchronize with the SaaS system using the Batch job scope

After processing 1000 records in a periodic synchronization of 1 lakh records, the replicas in which batch job instance was started went down due to unexpected failure in the runtime fabric environment

What is the consequence of losing the replicas that run the Batch job instance?

A.

The remaining 99000 records will be lost and left and processed

B.

The second replicas will take over processing the remaining

99000 records

C.

A new replacement replica will be available and will be process all 1,00,000 records from scratch leading to duplicate record processing

D.

A new placement replica will be available and will take or processing the remaining 99,000 records

Question # 3

What Is a recommended practice when designing an integration Mule 4 application that reads a large XML payload as a stream?

A.

The payload should be dealt with as a repeatable XML stream, which must only be traversed (iterated-over) once and CANNOT be accessed randomly from DataWeave expressions and scripts

B.

The payload should be dealt with as an XML stream, without converting it to a single Java object (POJO)

C.

The payload size should NOT exceed the maximum available heap memory of the Mute runtime on which the Mule application executes

D.

The payload must be cached using a Cache scope If It Is to be sent to multiple backend systems

Question # 4

Mule application is deployed to Customer Hosted Runtime. Asynchronous logging was implemented to improved throughput of the system. But it was observed over the period of time that few of the important exception log messages which were used to rollback transactions are not working as expected causing huge loss to the Organization. Organization wants to avoid these losses. Application also has constraints due to which they cant compromise on throughput much. What is the possible option in this case?

A.

Logging needs to be changed from asynchronous to synchronous

B.

External log appender needs to be used in this case

C.

Persistent memory storage should be used in such scenarios

D.

Mixed configuration of asynchronous or synchronous loggers should be used to log exceptions via synchronous way

Question # 5

A Mule application is synchronizing customer data between two different database systems.

What is the main benefit of using XA transaction over local transactions to synchronize these two database system?

A.

Reduce latency

B.

Increase throughput

C.

Simplifies communincation

D.

Ensure consistency

Question # 6

A leading eCommerce giant will use MuleSoft APIs on Runtime Fabric (RTF) to process customer orders. Some customer-sensitive information, such as credit card information, is required in request payloads or is included in response payloads in some of the APIs. Other API requests and responses are not authorized to access some of this customer-sensitive information but have been implemented to validate and transform based on the structure and format of this customer-sensitive information (such as account IDs, phone numbers, and postal codes).

What approach configures an API gateway to hide sensitive data exchanged between API consumers and API implementations, but can convert tokenized fields back to their original value for other API requests or responses, without having to recode the API implementations?

Later, the project team requires all API specifications to be augmented with an additional non-functional requirement (NFR) to protect the backend services from a high rate of requests, according to defined service-level

agreements (SLAs). The NFR ' s SLAs are based on a new tiered subscription level " Gold " , " Silver " , or " Platinum " that must be tied to a new parameter that is being added to the Accounts object in their enterprise data model.

Following MuleSoft ' s recommended best practices, how should the project team now convey the necessary non-functional requirement to stakeholders?

A.

Create and deploy API proxies in API Manager for the NFR, change the baseurl in each

API specification to the corresponding API proxy implementation endpoint, and publish each modified API specification to Exchange

B.

Update each API specification with comments about the NFR ' s SLAs and publish each modified API specification to Exchange

C.

Update each API specification with a shared RAML fragment required to implement the NFR and publish the RAML fragment and each modified API specification to Exchange

D.

Create a shared RAML fragment required to implement the NFR, list each API implementation endpoint in the RAML fragment, and publish the RAML fragment to Exchange

Question # 7

In Anypoint Platform, a company wants to configure multiple identity providers (IdPs) for multiple lines of business (LOBs). Multiple business groups, teams, and environments have been defined for these LOBs.

What Anypoint Platform feature can use multiple IdPs across the company’s business groups, teams, and environments?

A.

MuleSoft-hosted (CloudHub) dedicated load balancers

B.

Client (application) management

C.

Virtual private clouds

D.

Permissions

Question # 8

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

Question # 9

An organization is designing a Mule application to periodically poll an SFTP location for new files containing sales order records and then process those sales orders. Each sales order must be processed exactly once.

To support this requirement, the Mule application must identify and filter duplicate sales orders on the basis of a unique ID contained in each sales order record and then only send the new sales orders to the downstream system.

What is the most idiomatic (used for its intended purpose) Anypoint connector, validator, or scope that can be configured in the Mule application to filter duplicate sales orders on the basis of the unique ID field contained in each sales order record?

A.

Configure a Cache scope to filter and store each record from the received file by the order ID

B.

Configure a Database connector to filter and store each record by the order ID

C.

Configure an Idempotent Message Validator component to filter each record by the order ID

D.

Configure a watermark In an On New or Updated File event source to filter unique records by the order ID

Question # 10

The AnyAirline organization ' s passenger reservations center is designing an integration solution that combines invocations of three different System APIs (bookFlight, bookHotel, and bookCar) in a business transaction. Each System API makes calls to a single database.

The entire business transaction must be rolled back when at least one of the APIs fails.

What is the most idiomatic (used for its intended purpose) way to integrate these APIs in near real-time that provides the best balance of consistency, performance, and reliability?

A.

Implement eXtended Architecture (XA) transactions between the API implementations

Coordinate between the API implementations using a Saga pattern

Implement caching in each API implementation to improve performance

B.

Implement local transactions within each API implementation

Configure each API implementation to also participate in the same eXtended Architecture (XA) transaction

Implement caching in each API implementation to improve performance

C.

Implement local transactions in each API implementation

Coordinate between the API implementations using a Saga pattern

Apply various compensating actions depending on where a failure occurs

D.

Implement an eXtended Architecture (XA) transaction manager in a Mule application using a Saga pattern

Connect each API implementation with the Mule application using XA transactions

Apply various compensating actions depending on where a failure occurs
