NEW QUESTION 52
In which layer of API-led connectivity, does the business logic orchestration reside?
- A. System Layer
- B. Process Layer
- C. Experience Layer
Answer: B
Explanation:
Correct answer: Process Layer
*****************************************
>> Experience layer is dedicated for enrichment of end user experience. This layer is to meet the needs of different API clients/ consumers.
>> System layer is dedicated to APIs which are modular in nature and implement/ expose various individual functionalities of backend systems
>> Process layer is the place where simple or complex business orchestration logic is written by invoking one or many System layer modular APIs So, Process Layer is the right answer.
NEW QUESTION 53
How are an API implementation, API client, and API consumer combined to invoke and process an API?
- A. The ApI consumer creates an API client, which sends API invocations to an API such that they are processed by an API implementation
- B. The API consumer creates an API implementation, which receives API invocations from an API such that they are processed for an API client
- C. The ApI client creates an API consumer, which sends API invocations to an API such that they are processed by an API implementation
- D. The API client creates an API consumer, which receives API invocations from an API such that they are processed for an API implementation
Answer: B
NEW QUESTION 54

- A. Create an alert for when the API receives no requests within a specified time period
- B. Handle API invocation exceptions within the calling API client and raise an alert from that API client when the API Is unavailable
- C. Implement a heartbeat/health check within the API and invoke it from outside the Anypoint Platform and alert when the heartbeat does not respond
- D. Configure a "worker not responding" alert in Anypoint Runtime Manager
Answer: A
NEW QUESTION 55

- A. The API policy Is defined In API Manager for a specific API Instance, and then ONLY applied to the specific API instance
- B. The API policy Is defined In Runtime Manager as part of the API deployment to a Mule runtime, and then ONLY applied to the specific API Instance
- C. The API policy is defined in API Manager, and then applied to ALL API instances in the specified environment
- D. The API policy Is defined in API Manager and then automatically applied to ALL API instances
Answer: A
NEW QUESTION 56
What condition requires using a CloudHub Dedicated Load Balancer?
- A. When custom DNS names are required for API implementations deployed to customer-hosted Mule runtimes
- B. When API invocations across multiple CloudHub workers must be load balanced
- C. When cross-region load balancing is required between separate deployments of the same Mule application
- D. When server-side load-balanced TLS mutual authentication is required between API implementations and API clients
Answer: D
Explanation:
Correct answer: When server-side load-balanced TLS mutual authentication is required between API implementations and API clients
*****************************************
Fact/ Memory Tip: Although there are many benefits of CloudHub Dedicated Load balancer, TWO important things that should come to ones mind for considering it are:
>> Having URL endpoints with Custom DNS names on CloudHub deployed apps
>> Configuring custom certificates for both HTTPS and Two-way (Mutual) authentication.
Coming to the options provided for this
>> We
CANNOT use DLB to perform cross-region load balancing between separate deployments of the same Mule application.
>> We can have mapping rules to have more than one DLB URL pointing to same Mule app. But vicevera (More than one Mule app having same DLB URL) is NOT POSSIBLE
>> It is true that DLB helps to setup custom DNS names for Cloudhub deployed Mule apps but NOT true for apps deployed to Customer-hosted Mule Runtimes.
>> It is true to that we can load balance API invocations across multiple CloudHub workers using DLB but it is NOT A MUST. We can achieve the same (load balancing) using SLB (Shared Load Balancer) too. We DO NOT necessarily require DLB for achieve it.
So the only right option that fits the scenario and requires us to use DLB is when TLS mutual authentication is required between API implementations and API clients.
NEW QUESTION 57
An API implementation is updated. When must the RAML definition of the API also be updated?
- A. When the API implementation changes the structure of the request or response messages
- B. When the API implementation is migrated from an older to a newer version of the Mule runtime
- C. When the API implementation changes from interacting with a legacy backend system deployed on-premises to a modern, cloud-based (SaaS) system
- D. When the API implementation is optimized to improve its average response time
Answer: A
Explanation:
Correct answer: When the API implementation changes the structure of the request or response messages
*****************************************
>> RAML definition usually needs to be touched only when there are changes in the request/response schemas or in any traits on API.
>> It need not be modified for any internal changes in API implementation like performance tuning, backend system migrations etc..
NEW QUESTION 58
What condition requires using a CloudHub Dedicated Load Balancer?
- A. When server-side load-balanced TLS mutual authentication is required between API implementations and API clients
- B. When custom DNS names are required for API implementations deployed to customer-hosted Mule runtimes
- C. When API invocations across multiple CloudHub workers must be load balanced
- D. When cross-region load balancing is required between separate deployments of the same Mule application
Answer: B
NEW QUESTION 59
Refer to the exhibit.
What is the best way to decompose one end-to-end business process into a collaboration of Experience, Process, and System APIs?
A) Handle customizations for the end-user application at the Process API level rather than the Experience API level
B) Allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs
C) Always use a tiered approach by creating exactly one API for each of the 3 layers (Experience, Process and System APIs)
D) Use a Process API to orchestrate calls to multiple System APIs, but NOT to other Process APIs
- A. Option A
- B. Option B
- C. Option D
- D. Option C
Answer: B
Explanation:
Correct answer: Allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs.
*****************************************
>> All customizations for the end-user application should be handled in "Experience API" only. Not in Process API
>> We should use tiered approach but NOT always by creating exactly one API for each of the 3 layers. Experience APIs might be one but Process APIs and System APIs are often more than one. System APIs for sure will be more than one all the time as they are the smallest modular APIs built in front of end systems.
>> Process APIs can call System APIs as well as other Process APIs. There is no such anti-design pattern in API-Led connectivity saying Process APIs should not call other Process APIs.
So, the right answer in the given set of options that makes sense as per API-Led connectivity principles is to allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs. This way, some future Process APIs can make use of that data from System APIs and we need NOT touch the System layer APIs again and again.
