Question 1

An organization has various integrations implemented as Mule applications. Some of these Mule applications are deployed to custom hosted Mule runtimes (on-premises) while others execute in the MuleSoft-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 the backend systems?

Options :

A : 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

B : 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

C : 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

D : 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

Answer: D

Question 2

A mule application must periodically process a large dataset which varies from 6 GB lo 8 GB from a back-end database and write transform data lo an FTPS server using a properly configured bad job scope. The performance requirements of an application are approved to run in the cloud hub 0.2 vCore with 8 GB storage capacity and currency requirements are met. How can the high rate of records be effectively managed in this application?

Options :

A : Use streaming with a file storage repeatable strategy for reading records from the database and batch aggregator with streaming to write to FTPS

B : Use streaming with an in-memory reputable store strategy for reading records from the database and batch aggregator with streaming to write to FTPS

C : Use streaming with a file store repeatable strategy for reading records from the database and batch aggregator with an optimal size

D : Use streaming with a file store repeatable strategy reading records from the database and batch aggregator without any required configuration

Answer: A

Question 3

According to MuleSoft, a synchronous invocation of a RESTful API using HTTP to get an individual customer record from a single system is an example of which system integration interaction pattern?

Options :

A : Request-Reply

B : Multicast

C : Batch

D : One-way

Answer: A

Question 4

How are the API implementation , API client, and API consumer combined to invoke and process an API ?

Options :

A : The API consumer creates an API implementation , which receives API invocations from an API such that they are processed for an API client

B : The API consumer creates an API client which sends API invocations to an API such that they are processed by an API implementation

C : An API client creates an API consumer, which receives API invocation from an API such that they are processed for an API implementation

D : The API client creates an API consumer which sends API invocations to an API such that they are processed by API implementation

Answer: C

Question 5

Additional nodes are being added to an existing customer-hosted Mule runtime cluster to improve performance. Mule applications deployed to this cluster are invoked by API clients through a load balancer. What is also required to carry out this change?

Options :

A : A new load balancer must be provisioned to allow traffic to the new nodes in a round-robin fashion

B : External monitoring tools or log aggregators must be configured to recognize the new nodes

C : API implementations using an object store must be adjusted to recognize the new nodes and persist to them

D : New firewall rules must be configured to accommodate communication between API clients and the new nodes
