Salesforce MuleSoft-Platform-Architect-I Sample Question Answers

Question # 1

When designing an upstream API and its implementation, the development team has beenadvised to NOT set timeouts when invoking a downstream API, because that downstreamAPI has no SLA that can be relied upon. This is the only downstream API dependency ofthat upstream API.Assume the downstream API runs uninterrupted without crashing. What is the impact ofthis advice?

A. An SLA for the upstream API CANNOT be provided
B. The invocation of the downstream API will run to completion without timing out
C. A default timeout of 500 ms will automatically be applied by the Mule runtime in whichthe upstream API implementation executes
D. A toad-dependent timeout of less than 1000 ms will be applied by the Mule runtime inwhich the downstream API implementation executes

Question # 2

4A developer for a transportation organization is implementing exactly one processingfunctionality in a Reservation Mule application to process and store passengerrecords. This Reservation application will be deployed to multiple CloudHubworkers/replicas. It is possible that several external systems could send duplicatepassenger recordsto the Reservation application.An appropriate storage mechanism must be selected to help the Reservation applicationprocess each passenger record exactly once as much as possible. The selected storagemechanism must be shared by all the CloudHub workers/replicas in order to synchronizethe state information to assist attempting exactly once processing of each passengerrecord by the deployed Reservation Mule application.Which type of simple storage mechanism in Anypoint Platform allows the Reservation Muleapplication to update and share data between the CloudHub workers/replicas exactlyonce, with minimal development effort?

A. Persistent Object Store
B. Runtime Fabric Object Store
C. Non-persistent Object Store
D. In-memory Mule Object Store

Question # 4

An operations team is analyzing the effort needed to set up monitoring of their applicationnetwork. They are looking at which API invocation metrics can be used to identify andpredict trouble without having to write custom scripts or install additional analytics softwareor tools.Which type of metrics can satisfy this goal of directly identifying and predicting failures?

A. The number and types of API policy violations per day 
B. The effectiveness of the application network based on the level of reuse 
C. The number and types of past API invocations across the application network 
D. The ROI from each APT invocation

Question # 5

What is a best practice when building System APIs?

A. Document the API using an easily consumable asset like a RAML definition
B. Model all API resources and methods to closely mimic the operations of the backendsystem
C. Build an Enterprise Data Model (Canonical Data Model) for each backend system andapply it to System APIs
D. Expose to API clients all technical details of the API implementation's interaction wifchthe backend system

Question # 6

What should be ensured before sharing an API through a public Anypoint Exchange portal?

A. The visibility level of the API instances of that API that need to be publicly accessibleshould be set to public visibility
B. The users needing access to the API should be added to the appropriate role inAnypoint Platform
C. The API should be functional with at least an initial implementation deployed andaccessible for users to interact with
D. The API should be secured using one of the supported authentication/authorizationmechanisms to ensure that data is not compromised

Question # 7

A European company has customers all across Europe, and the IT department is migratingfrom an older platform to MuleSoft. The main requirements are that the new platform should allow redeployments with zero downtime and deployment ofapplications to multiple runtime versions, provide security and speed, and utilize AnypointMQas the message service.Which runtime plane should the company select based on the requirements withoutadditional network configuration? 

A. Runtime Fabric on VMs / Bare Metal for the runtime plane 
B. Customer-hosted runtime plane 
C. MuleSoft-hosted runtime plane (CloudHub) 
D. Anypoint Runtime Fabric on Self-Managed Kubernetes for the runtime plane

Question # 8

A system API has a guaranteed SLA of 100 ms per request. The system API is deployed toa primary environment as well as to a disaster recovery (DR) environment, with differentDNS names in each environment. An upstream process API invokes the system API andthe main goal of this process API is to respond to client requests in the least possible time.In what order should the system APIs be invoked, and what changes should be made inorder to speed up the response time for requests from the process API?

A. In parallel, invoke the system API deployed to the primary environment and the systemAPI deployed to the DR environment, and ONLY use the first response
B. In parallel, invoke the system API deployed to the primary environment and the systemAPI deployed to the DR environment using a scatter-gather configured with a timeout, andthen merge the responses
C. Invoke the system API deployed to the primary environment, and if it fails, invoke thesystem API deployed to the DR environment
D. Invoke ONLY the system API deployed to the primary environment, and add timeout andretry logic to avoid intermittent failures

B. OpenAPI Specification (OAS)
C. YAML
D. AsyncAPI Specification

Question # 10

An API implementation is updated. When must the RAML definition of the API also beupdated?

A. When the API implementation changes the structure of the request or responsemessages
B. When the API implementation changes from interacting with a legacy backend systemdeployed on-premises to a modern, cloud-based (SaaS) system
C. When the API implementation is migrated from an older to a newer version of the Muleruntime
D. When the API implementation is optimized to improve its average response time
