Anypoint Platform to the endpoint exposed by that Mule application?
A) A Mule application that accepts requests over HTTP/1.x
A.
Option A
B.
Option B
C.
Option C
D.
Option D
Option A
Explanation: Explanation
Correct Answer: Option A
*****************************************
>> Anypoint API Manager and API policies are applicable to all types of HTTP/1.x APIs.
>> They are not applicable to WebSocket APIs, HTTP/2 APIs and gRPC APIs
Reference: https://docs.mulesoft.com/api-manager/2.x/using-policies
Which component monitors APIs and endpoints at scheduled intervals, receives reports about whether tests pass or fail, and displays statistics about API and endpoint performance?
A. API Analytics
B. Anypoint Monitoring dashboards
C. APT Functional Monitoring
D. Anypoint Runtime Manager alerts
Explanation:
An API implementation is deployed to CloudHub.
What conditions can be alerted on using the default Anypoint Platform functionality, where
the alert conditions depend on the end-to-end request processing of the API
implementation?
A.
When the API is invoked by an unrecognized API client
B.
When a particular API client invokes the API too often within a given time period
C.
When the response time of API invocations exceeds a threshold
D.
When the API receives a very high number of API invocations
When the response time of API invocations exceeds a threshold
Explanation: Explanation
Correct Answer: When the response time of API invocations exceeds a threshold
*****************************************
>> Alerts can be setup for all the given options using the default Anypoint Platform
functionality
>> However, the question insists on an alert whose conditions depend on the end-to-end
request processing of the API implementation.
>> Alert w.r.t "Response Times" is the only one which requires end-to-end request
processing of API implementation in order to determine if the threshold is exceeded or not.

Refer to the exhibit.
A.
Option A
B.
Option B
C.
Option C
D.
Option D
Option D
Explanation: Explanation
Correct Answer: XML over HTTP
*****************************************
>> API-led connectivity and Application Networks urge to have the APIs on HTTP based
protocols for building most effective APIs and networks on top of them.
>> The HTTP based APIs allow the platform to apply various varities of policies to address
many NFRs
>> The HTTP based APIs also allow to implement many standard and effective
implementation patterns that adhere to HTTP based w3c rules
A circuit breaker strategy is planned in order to meet the goal of improved response time
and demand on a downstream API.
A. Create a custom policy that implements the circuit breaker and includes policy template expressions for the required settings
B. Create Anypoint Monitoring alerts for Circuit Open/Closed configurations, and then implement a retry strategy for Circuit Half-Open configuration
C. Add the Circuit Breaker policy to the API instance, and configure the required settings
D. Implement the strategy in a Mule application, and provide the settings in the YAML configuration
Say, there is a legacy CRM system called CRM-Z which is offering below functions:
1. Customer creation
2. Amend details of an existing customer
3. Retrieve details of a customer
4. Suspend a customer
A.
Implement a system API named customerManagement which has all the functionalities
wrapped in it as various operations/resources
B.
Implement different system APIs named createCustomer, amendCustomer,
retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns
C.
Implement different system APIs named createCustomerInCRMZ,
amendCustomerInCRMZ, retrieveCustomerFromCRMZ and suspendCustomerInCRMZ as
they are modular and has seperation of concerns
Implement different system APIs named createCustomer, amendCustomer,
retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns
Correct Answer: Implement different system APIs named createCustomer,
amendCustomer, retrieveCustomer and suspendCustomer as they are modular and has
seperation of concerns
*****************************************
>> It is quite normal to have a single API and different Verb + Resource combinations.
However, this fits well for an Experience API or a Process API but not a best architecture
style for System APIs. So, option with just one customerManagement API is not the best
choice here.
>> The option with APIs in createCustomerInCRMZ format is next close choice w.r.t
modularization and less maintenance but the naming of APIs is directly coupled with the
legacy system. A better foreseen approach would be to name your APIs by abstracting the
backend system names as it allows seamless replacement/migration of any backend
system anytime. So, this is not the correct choice too.
>> createCustomer, amendCustomer, retrieveCustomer and suspendCustomer is the right
approach and is the best fit compared to other options as they are both modular and same
time got the names decoupled from backend system and it has covered all requirements a
System API needs.
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
What best describes the Fully Qualified Domain Names (FQDNs), also known as DNS entries, created when a Mule application is deployed to the CloudHub Shared Worker Cloud?
A.
A fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design
B.
The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region
C.
The FQDNs are determined by the application name, but can be modified by an
administrator after deployment
D.
The FQDNs are determined by both the application name and the Anypoint Platform
organization
The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region
Explanation: Explanation
Correct Answer: The FQDNs are determined by the application name chosen,
IRRESPECTIVE of the region
*****************************************
>> When deploying applications to Shared Worker Cloud, the FQDN are always
determined by application name chosen.
>> It does NOT matter what region the app is being deployed to.
>> Although it is fact and true that the generated FQDN will have the region included in it
(Ex: exp-salesorder-api.au-s1.cloudhub.io), it does NOT mean that the same name can be
used when deploying to another CloudHub region.
>> Application name should be universally unique irrespective of Region and Organization
and solely determines the FQDN for Shared Load Balancers
