An organization has implemented a Customer Address API to retrieve customer address
information. This API has been deployed to multiple environments and has been configured
to enforce client IDs everywhere.
A developer is writing a client application to allow a user to update their address. The
developer has found the Customer Address API in Anypoint Exchange and wants to use it
in their client application.
What step of gaining access to the API can be performed automatically by Anypoint
Platform?
A.
Approve the client application request for the chosen SLA tier
B.
Request access to the appropriate API Instances deployed to multiple environments using the client application's credentials
C.
Modify the client application to call the API using the client application's credentials
D.
Create a new application in Anypoint Exchange for requesting access to the API
Approve the client application request for the chosen SLA tier
Explanation: Explanation
Correct Answer: Approve the client application request for the chosen SLA tier
*****************************************
>> Only approving the client application request for the chosen SLA tier can be automated
>> Rest of the provided options are not valid
Reference: https://docs.mulesoft.com/api-manager/2.x/defining-sla-tiers#defining-a-tier
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?
A.
The client ID and secret for the Anypoint Platform account owning the API in the STAGING environment
B.
The client ID and secret for the Anypoint Platform account's STAGING environment
C.
The client ID and secret obtained from Anypoint Exchange for the API instance in the
STAGING environment
D.
A valid OAuth token obtained from Anypoint Platform and its associated client ID and
secret
The client ID and secret obtained from Anypoint Exchange for the API instance in the
STAGING environment
Explanation: Explanation
Correct Answer: The client ID and secret obtained from Anypoint Exchange for the API
instance in the STAGING environment
*****************************************
>> We CANNOT use the client ID and secret of Anypoint Platform account or any individual
environments for accessing the APIs
>> As the type of policy that is enforced on the API in question is "Client ID Enforcment
Policy", OAuth token based access won't work.
Right way to access the API is to use the client ID and secret obtained from Anypoint
Exchange for the API instance in a particular environment we want to work on.

What condition requires using a CloudHub Dedicated Load Balancer?
A.
When cross-region load balancing is required between separate deployments of the same Mule application
B.
When custom DNS names are required for API implementations deployed to customerhosted Mule runtimes
C.
When API invocations across multiple CloudHub workers must be load balanced
D.
When server-side load-balanced TLS mutual authentication is required between API
implementations and API clients
When server-side load-balanced TLS mutual authentication is required between API
implementations and API clients
Explanation: 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 question:
>> 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.

Which two statements are true about the technology architecture of an Anypoint Virtual
Private Cloud (VPC)?
(Choose 2 answers)
A. Ports 8081 and 8082 are used
B. CIDR blacks are used
C. Anypoint VPC is responsible for load balancing the applications
D. Round-robin load balancing is used to distribute client requests across different applications
E. By default, HTTP requests can be made from the public internet to workers at port 6091
Explanation:
An Anypoint Virtual Private Cloud (VPC) provides a secure and private
networking environment for MuleSoft applications, using specific architectural elements:
A company has started to create an application network and is now planning to implement a Center for Enablement (C4E) organizational model. What key factor would lead the company to decide upon a federated rather than a centralized C4E?
A.
When there are a large number of existing common assets shared by development teams
B.
When various teams responsible for creating APIs are new to integration and hence need extensive training
C.
When development is already organized into several independent initiatives or groups
D.
When the majority of the applications in the application network are cloud based
When development is already organized into several independent initiatives or groups
Explanation: Explanation
Correct Answer: When development is already organized into several independent
initiatives or groups
*****************************************
>> It would require lot of process effort in an organization to have a single C4E team
coordinating with multiple already organized development teams which are into several
independent initiatives. A single C4E works well with different teams having at least a
common initiative. So, in this scenario, federated C4E works well instead of centralized
C4E.
What Anypoint Connectors support transactions?
A.
Database, JMS, VM
B.
Database, 3MS, HTTP
C.
Database, JMS, VM, SFTP
D.
Database, VM, File
Database, JMS, VM
A Mule application exposes an HTTPS endpoint and is deployed to the CloudHub Shared Worker Cloud. All traffic to that Mule application must stay inside the AWS VPC. To what TCP port do API invocations to that Mule application need to be sent?
A. 443
B. 8081
C. 8091
D. 8082
Explanation:
Correct Answer: 8082
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 changes from interacting with a legacy backend system deployed 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 Mule runtime
D.
When the API implementation is optimized to improve its average response time
When the API implementation changes the structure of the request or response messages
Explanation: 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
