QUESTION 37
A company wants to move its Mule API implementations into production as quickly as possible. To protect access to all Mule application data and metadata, the company requires that all Mule applications be deployed to the company’s customer-hosted infrastructure within the corporate firewall. What combination of runtime plane and control plane options meets these project lifecycle goals?

Manually provisioned customer-hosted runtime plane and customer-hosted control plane

MuleSoft-hosted runtime plane and customer-hosted control plane

Manually provisioned customer-hosted runtime plane and MuleSoft-hosted control plane

iPaaS provisioned customer-hosted runtime plane and MuleSoft-hosted control plane

Correct answer: Manually provisioned customer-hosted runtime plane and customer-hosted control plane
*****************************************
There are two key factors that are to be taken into consideration from the scenario given in the question.
>> Company requires both data and metadata to be resided within the corporate firewall
>> Company would like to go with customer-hosted infrastructure.
Any deployment model that is to deal with the cloud directly or indirectly (Mulesoft-hosted or Customer’s own cloud like Azure, AWS) will have to share atleast the metadata.
Application data can be controlled inside firewall by having Mule Runtimes on customer hosted runtime plane. But if we go with Mulsoft-hosted/ Cloud-based control plane, the control plane required atleast some minimum level of metadata to be sent outside the corporate firewall.
As the customer requirement is pretty clear about the data and metadata both to be within the corporate firewall, even though customer wants to move to production as quickly as possible, unfortunately due to the nature of their security requirements, they have no other option but to go with manually provisioned customer-hosted runtime plane and customer-hosted control plane.

QUESTION 38
What condition requires using a CloudHub Dedicated Load Balancer?

When cross-region load balancing is required between separate deployments of the same Mule application

When custom DNS names are required for API implementations deployed to customer-hosted Mule runtimes

When API invocations across multiple CloudHub workers must be load balanced

When server-side load-balanced TLS mutual authentication is required between API implementations and API clients

QUESTION 39
What is typically NOT a function of the APIs created within the framework called API-led connectivity?

They provide an additional layer of resilience on top of the underlying backend system, thereby insulating clients from extended failure of these systems.

They allow for innovation at the user Interface level by consuming the underlying assets without being aware of how data Is being extracted from backend systems.

They reduce the dependency on the underlying backend systems by helping unlock data from backend systems In a reusable and consumable way.

They can compose data from various sources and combine them with orchestration logic to create higher level value.

Correct answer: They provide an additional layer of resilience on top of the underlying backend system, thereby insulating clients from extended failure of these systems.
*****************************************
In API-led connectivity,
>> Experience APIs – allow for innovation at the user interface level by consuming the underlying assets without being aware of how data is being extracted from backend systems.
>> Process APIs – compose data from various sources and combine them with orchestration logic to create higher level value
>> System APIs – reduce the dependency on the underlying backend systems by helping unlock data from backend systems in a reusable and consumable way.
However, they NEVER promise that they provide an additional layer of resilience on top of the underlying backend system, thereby insulating clients from extended failure of these systems.

QUESTION 40
What should be ensured before sharing an API through a public Anypoint Exchange portal?

The visibility level of the API instances of that API that need to be publicly accessible should be set to public visibility

The users needing access to the API should be added to the appropriate role in Anypoint Platform

The API should be functional with at least an initial implementation deployed and accessible for users to interact with

The API should be secured using one of the supported authentication/authorization mechanisms to ensure that data is not compromised

Correct answer: The visibility level of the API instances of that API that need to be publicly accessible should be set to public visibility.

QUESTION 41
When using CloudHub with the Shared Load Balancer, what is managed EXCLUSIVELY by the API implementation (the Mule application) and NOT by Anypoint Platform?

The assignment of each HTTP request to a particular CloudHub worker

The logging configuration that enables log entries to be visible in Runtime Manager

The SSL certificates used by the API implementation to expose HTTPS endpoints

The number of DNS entries allocated to the API implementation

QUESTION 42
The responses to some HTTP requests can be cached depending on the HTTP verb used in the request.
According to the HTTP specification, for what HTTP verbs is this safe to do?

PUT, POST, DELETE

GET, HEAD, POST

GET, PUT, OPTIONS

GET, OPTIONS, HEAD

QUESTION 43
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 fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design

The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region

The FQDNs are determined by the application name, but can be modified by an administrator after deployment

The FQDNs are determined by both the application name and the Anypoint Platform organization

QUESTION 44
What best explains the use of auto-discovery in API implementations?

It makes API Manager aware of API implementations and hence enables it to enforce policies

It enables Anypoint Studio to discover API definitions configured in Anypoint Platform

It enables Anypoint Exchange to discover assets and makes them available for reuse

It enables Anypoint Analytics to gain insight into the usage of APIs

QUESTION 45
Refer to the exhibit.

Three business processes need to be implemented, and the implementations need to communicate with several different SaaS applications.
These processes are owned by separate (siloed) LOBs and are mainly independent of each other, but do share a few business entities. Each LOB has one development team and their own budget In this organizational context, what is the most effective approach to choose the API data models for the APIs that will implement these business processes with minimal redundancy of the data models?
A) Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities

B) Build distinct data models for each API to follow established micro-services and Agile API-centric practices

C) Build all API data models using XML schema to drive consistency and reuse across the organization

D) Build one centralized Canonical Data Model (Enterprise Data Model) that unifies all the data types from all three business processes, ensuring the data model is consistent and non-redundant

Option A

Option B

Option C

Option D

Correct answer: Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities.
*****************************************
>> The options w.r.t building API data models using XML schema/ Agile API-centric practices are irrelevant to the scenario given in the question. So these two are INVALID.
>> Building EDM (Enterprise Data Model) is not feasible or right fit for this scenario as the teams and LOBs work in silo and they all have different initiatives, budget etc.. Building EDM needs intensive coordination among all the team which evidently seems not possible in this scenario.
So, the right fit for this scenario is to build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities.

QUESTION 46
Refer to the exhibit.

A developer is building a client application to invoke an API deployed to the STAGING environment that is governed by a client ID enforcement policy.
What is required to successfully invoke the API?

The client ID and secret for the Anypoint Platform account owning the API in the STAGING environment

The client ID and secret for the Anypoint Platform account’s STAGING environment

The client ID and secret obtained from Anypoint Exchange for the API instance in the STAGING environment

A valid OAuth token obtained from Anypoint Platform and its associated client ID and secret

Explanation

QUESTION 47
What is a best practice when building System APIs?

Document the API using an easily consumable asset like a RAML definition

Model all API resources and methods to closely mimic the operations of the backend system

Build an Enterprise Data Model (Canonical Data Model) for each backend system and apply it to System APIs

Expose to API clients all technical details of the API implementation’s interaction wifch the backend system

Correct answer: Model all API resources and methods to closely mimic the operations of the backend system.
*****************************************
>> There are NO fixed and straight best practices while opting data models for APIs. They are completly contextual and depends on number of factors. Based upon those factors, an enterprise can choose if they have to go with Enterprise Canonical Data Model or Bounded Context Model etc.
>> One should NEVER expose the technical details of API implementation to their API clients. Only the API interface/ RAML is exposed to API clients.
>> It is true that the RAML definitions of APIs should be as detailed as possible and should reflect most of the documentation. However, just that is NOT enough to call your API as best documented API. There should be even more documentation on Anypoint Exchange with API Notebooks etc. to make and create a developer friendly API and repository..
>> The best practice always when creating System APIs is to create their API interfaces by modeling their resources and methods to closely reflect the operations and functionalities of that backend system.

QUESTION 48
Refer to the exhibit.

An organization uses one specific CloudHub (AWS) region for all CloudHub deployments.
How are CloudHub workers assigned to availability zones (AZs) when the organization’s Mule applications are deployed to CloudHub in that region?

Workers belonging to a given environment are assigned to the same AZ within that region

AZs are selected as part of the Mule application’s deployment configuration

Workers are randomly distributed across available AZs within that region

An AZ is randomly selected for a Mule application, and all the Mule application’s CloudHub workers are assigned to that one AZ

QUESTION 49
Refer to the exhibit.

what is true when using customer-hosted Mule runtimes with the MuleSoft-hosted Anypoint Platform control plane (hybrid deployment)?

Anypoint Runtime Manager initiates a network connection to a Mule runtime in order to deploy Mule applications

The MuleSoft-hosted Shared Load Balancer can be used to load balance API invocations to the Mule runtimes

API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane

Anypoint Runtime Manager automatically ensures HA in the control plane by creating a new Mule runtime instance in case of a node failure

Correct answer: API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane.
*****************************************
>> We CANNOT use Shared Load balancer to load balance APIs on customer hosted runtimes

>> For Hybrid deployment models, the on-premises are first connected to Runtime Manager using Runtime Manager agent. So, the connection is initiated first from On-premises to Runtime Manager. Then all control can be done from Runtime Manager.
>> Anypoint Runtime Manager CANNOT ensure automatic HA. Clusters/Server Groups etc should be configured before hand.
Only TRUE statement in the given choices is, API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane. There are several references below to justify this statement.

QUESTION 50
What CANNOT be effectively enforced using an API policy in Anypoint Platform?

Guarding against Denial of Service attacks

Maintaining tamper-proof credentials between APIs

Logging HTTP requests and responses

Backend system overloading

Correct answer: Guarding against Denial of Service attacks
*****************************************
>> Backend system overloading can be handled by enforcing “Spike Control Policy”
>> Logging HTTP requests and responses can be done by enforcing “Message Logging Policy”
>> Credentials can be tamper-proofed using “Security” and “Compliance” Policies However, unfortunately, there is no proper way currently on Anypoint Platform to guard against DOS attacks.
