Question 1

Mule application A receives a request Anypoint MQ message REQU with a payload containing a variable-length list of request objects. Application A uses the For Each scope to split the list into individual objects and sends each object as a message to an Anypoint MQ queue. Service S listens on that queue, processes each message independently of all other messages, and sends a response message to a response queue. Application A listens on that response queue and must in turn create and publish a response Anypoint MQ message RESP with a payload containing the list of responses sent by service S in the same order as the request objects originally sent in REQU. Assume successful response messages are returned by service S for all request messages. What is required so that application A can ensure that the length and order of the list of objects in RESP and REQU match, while at the same time maximizing message throughput?

A : Use a Scatter-Gather within the For Each scope to ensure response message order Configure the Scatter-Gather with a persistent object store

B : Perform all communication involving service S synchronously from within the For Each scope, so objects in RESP are in the exact same order as request objects in REQU

C : Use an Async scope within the For Each scope and collect response messages in a second For Each scope in the order In which they arrive, then send RESP using this list of responses

D : Keep track of the list length and all object indices in REQU, both in the For Each scope and in all communication involving service Use persistent storage when creating RESP

Answer: D

Question 2

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

A : Component

B : interaction

C : Message

D : Interface

Answer: D

Question 3

A company is planning to migrate its deployment environment from on-premises cluster to a Runtime Fabric (RTF) cluster. It also has a requirement to enable Mule applications deployed to a Mule runtime instance to store and share data across application replicas and restarts. How can these requirements be met?

A : Anypoint object store V2 to share data between replicas in the RTF cluster

B : Install the object store pod on one of the cluster nodes

C : Configure Persistence Gateway in any of the servers using Mule Object Store

D : Configure Persistent Gateway at the RTF

Answer: A

Question 4

Refer to the exhibit.An organization is sizing an Anypoint VPC for the non-production deployments of those Mule applications that connect to the organization's on-premises systems. This applies to approx. 60 Mule applications. Each application is deployed to two CloudHub i workers. The organization currently has three non-production environments (DEV, SIT and UAT) that share this VPC. The AWS region of the VPC has two AZs. The organization has a very mature DevOps approach which automatically progresses each application through all non-production environments before automatically deploying to production. This process results in several Mule application deployments per hour, using CloudHub's normal zero-downtime deployment feature. What is a CIDR block for this VPC that results in the smallest usable private IP address range?

A : 10.0.0.0/26 (64 IPS)

B : 10.0.0.0/25 (128 IPs)

C : 10.0.0.0/24 (256 IPs)

D : 10.0.0.0/22 (1024 IPs)

Answer: D

Question 5

A system API EmployeeSAPI is used to fetch employee's data from an underlying SQL database. The architect must design a caching strategy to query the database only when there is an update to the employees stable or else return a cached response in order to minimize the number of redundant transactions being handled by the database. What must the architect do to achieve the caching objective?

A : Use an On Table Row on employees table and call invalidate cache Use an object store caching strategy and expiration interval to empty

B : Use a Scheduler with a fixed frequency every hour triggering an invalidate cache flow Use an object store caching strategy and expiration interval to empty

C : Use a Scheduler with a fixed frequency every hour triggering an invalidate cache flow Use an object store caching strategy and set expiration interval to 1-hour

D : Use an on table rule on employees table call invalidate cache and said new employees data to cache Use an object store caching strategy and set expiration interval to 1-hour

Answer: A
