QUESTION: 25

What Mule application deployment scenario requires using Anypoint Platform Private Cloud Edition or Anypoint Platform for Pivotal Cloud Foundry?

When it Is required to make ALL applications highly available across multiple data centers
When it is required that ALL APIs are private and NOT exposed to the public cloud
When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data
When ALL backend systems in the application network are deployed in the organization's intranet

Answer(s): C

Explanation:

Correct Answer: When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data.
*****************************************
We need NOT require to use Anypoint Platform PCE or PCF for the below. So these options are OUT. >> We can make ALL applications highly available across multiple data centers using CloudHub too. >> We can use Anypoint VPN and tunneling from CloudHub to connect to ALL backend systems in the application network that are deployed in the organization's intranet. >> We can use Anypoint VPC and Firewall Rules to make ALL APIs private and NOT exposed to the public cloud.
Only valid reason in the given options that requires to use Anypoint Platform PCE/ PCF is - When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data.

QUESTION: 26

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.

Answer(s): A

Explanation:

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: 27

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?

Approve the client application request for the chosen SLA tier
Request access to the appropriate API Instances deployed to multiple environments using the client application's credentials
Modify the client application to call the API using the client application's credentials
Create a new application in Anypoint Exchange for requesting access to the API

Answer(s): A

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

QUESTION: 28

What is a typical result of using a fine-grained rather than a coarse-grained API deployment model to implement a given business process?

A decrease in the number of connections within the application network supporting the business process
A higher number of discoverable API-related assets in the application network
A better response time for the end user as a result of the APIs being smaller in scope and complexity
An overall tower usage of resources because each fine-grained API consumes less resources

Answer(s): B

Explanation:

Correct Answer: A higher number of discoverable API-related assets in the application network.
*****************************************
>> We do NOT get faster response times in fine-grained approach when compared to coarse-grained approach.
>> In fact, we get faster response times from a network having coarse-grained APIs compared to a network having fine-grained APIs model. The reasons are below.
Fine-grained approach:
1. will have more APIs compared to coarse-grained
2. So, more orchestration needs to be done to achieve a functionality in business process.
3. Which means, lots of API calls to be made. So, more connections will needs to be established. So, obviously more hops, more network i/o, more number of integration points compared to coarse- grained approach where fewer APIs with bulk functionality embedded in them.
4. That is why, because of all these extra hops and added latencies, fine-grained approach will have bit more response times compared to coarse-grained.
5. Not only added latencies and connections, there will be more resources used up in fine-grained approach due to more number of APIs.
That's why, fine-grained APIs are good in a way to expose more number of resuable assets in your network and make them discoverable. However, needs more maintenance, taking care of integration points, connections, resources with a little compromise w.r.t network hops and response times.
