A system API has a guaranteed SLA of 100 ms per request. The system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. An upstream process API invokes the system API and the 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 in order 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 system API 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 system API deployed to the DR environment using a scatter-gather configured with a timeout, and then merge the responses
C. Invoke the system API deployed to the primary environment, and if it fails, invoke the system API deployed to the DR environment
D. Invoke ONLY the system API deployed to the primary environment, and add timeout and retry logic to avoid intermittent failures
Explanation: Explanation
Correct Answer: In parallel, invoke the system API deployed to the primary environment
and the system API deployed to the DR environment, and ONLY use the first response.
*****************************************
>> The API requirement in the given scenario is to respond in least possible time.
>> The option that is suggesting to first try the API in primary environment and then
fallback to API in DR environment would result in successful response but NOT in least
possible time. So, this is NOT a right choice of implementation for given requirement.
>> Another option that is suggesting to ONLY invoke API in primary environment and to
add timeout and retries may also result in successful response upon retries but NOT in
least possible time. So, this is also NOT a right choice of implementation for given
requirement.
>> One more option that is suggesting to invoke API in primary environment and API in DR
environment in parallel using Scatter-Gather would result in wrong API response as it
would return merged results and moreover, Scatter-Gather does things in parallel which is
true but still completes its scope only on finishing all routes inside it. So again, NOT a right
choice of implementation for given requirement
The Correct choice is to invoke the API in primary environment and the API in DR
environment parallelly, and using ONLY the first response received from one of them
The asset version 2.0.0 of the Order API is successfully published in Exchange and configured in API Manager with the Autodiscovery API ID correctly linked to the API implementation, A new GET method is added to the existing API specification, and after updates, the asset version of the Order API is 2.0.1. What happens to the Autodiscovery API ID when the new asset version is updated in API Manager?
A. The API ID changes, but no changes are needed to the API implementation for the new asset version in the API Autediscovery global element because the API ID is automatically updated
B. The APL ID changes, so the API implementation must be updated with the latest API ID for the new asset version in the API Autodiscovery global element
C. The APLID does not change, so no changes to the APT implementation are needed for the new asset version in the API Autodiscovery global element
D. The APL ID does not change, but the API implementation must be updated in the AP] Autodiscovery global element to indicate the new asset version 2.0.4

What are the major benefits of MuleSoft proposed IT Operating Model?
A.
1. Decrease the IT delivery gap
2. Meet various business demands without increasing the IT capacity
3. Focus on creation of reusable assets first. Upon finishing creation of all the possible
assets then inform the LOBs in the organization to start using them
B.
1. Decrease the IT delivery gap
2. Meet various business demands by increasing the IT capacity and forming various IT
departments
3. Make consumption of assets at the rate of production
C.
1. Decrease the IT delivery gap
2. Meet various business demands without increasing the IT capacity
3. Make consumption of assets at the rate of production
1. Decrease the IT delivery gap
2. Meet various business demands without increasing the IT capacity

An online store's marketing team has noticed an increase in customers leaving online baskets without checking out. They suspect a technology issue is at the root cause of the baskets being left behind. They approach the Center for Enablement to ask for help identifying the issue. Multiple APIs from across all the layers of their application network are involved in the shopping application. Which feature of the Anypoint Platform can be used to view metrics from all involved APIs at the same time?
A. Custom dashboards
B. Built-in dashboards
C. Functional monitoring
D. API Manager
Traffic is routed through an API proxy to an API implementation. The API proxy is managed
by API Manager and the API implementation is deployed to a CloudHub VPC using
Runtime Manager. API policies have been applied to this API. In this deployment scenario,
at what point are the API policies enforced on incoming API client requests?
A.
At the API proxy
B.
At the API implementation
C.
At both the API proxy and the API implementation
D.
At a MuleSoft-hosted load balancer
At the API proxy
Explanation: Explanation
Correct Answer: At the API proxy
*****************************************
>> API Policies can be enforced at two places in Mule platform.
>> One - As an Embedded Policy enforcement in the same Mule Runtime where API
implementation is running.
>> Two - On an API Proxy sitting in front of the Mule Runtime where API implementation is
running.
>> As the deployment scenario in the question has API Proxy involved, the policies will be
enforced at the API Proxy.
A team is planning to enhance an Experience API specification, and they are following APIled connectivity design principles. What is their motivation for enhancing the API?
A. The primary API consumer wants certain kinds of endpoints changed from the Center for Enablement standard to the consumer system standard
B. The underlying System API is updated to provide more detailed data for several heavily used resources
C. An IP Allowlist policy is being added to the API instances in the Development and Staging environments
D. A Canonical Data Model is being adopted that impacts several types of data included in the API
Explanation:
In API-led design, an Experience API is enhanced to improve how data is
delivered to end-user applications. One primary reason to enhance an Experience API is
when new data standards, such as a Canonical Data Model, are adopted. Here’s why:
A REST API is being designed to implement a Mule application.

Web Service Definition Language(WSDL)
B.
OpenAPI Specification (OAS)
C.
YAML
D.
AsyncAPI Specification
OpenAPI Specification (OAS)
