Question 2 Single choice

A team is planning to enhance an Experience API specification, and they are following API-led connectivity design principles.

What is their motivation for enhancing the API?

  1. A

    The primary API consumer wants certain kinds of endpoints changed from the Center for Enablement standard to the consumer system standard

  2. B

    The underlying System API is updated to provide more detailed data for several heavily used resources

  3. C

    An IP Allowlist policy is being added to the API instances in the Development and Staging environments

  4. D

    A Canonical Data Model is being adopted that impacts several types of data included in the API

Show answer and explanation

Correct answer: D

Question 3 Single choice

An organization makes a strategic decision to move towards an IT operating model that emphasizes consumption of reusable IT assets using modern APIs (as defined by MuleSoft).

What best describes each modern API in relation to this new IT operating model?

  1. A

    Each modern API has its own software development lifecycle, which reduces the need for documentation and automation

  2. B

    Each modem API must be treated like a product and designed for a particular target audience (for
    instance, mobile app developers)

  3. C

    Each modern API must be easy to consume, so should avoid complex authentication mechanisms such as SAML or JWT D

  4. D

    Each modern API must be REST and HTTP based

Show answer and explanation

Correct answer: B

Question 4 Single choice

When designing an upstream API and its implementation, the development team has been advised to NOT set timeouts when invoking a downstream API, because that downstream API has no SLA that can be relied upon. This is the only downstream API dependency of that upstream API. Assume the downstream API runs uninterrupted without crashing.

What is the impact of this advice?

  1. A

    An SLA for the upstream API CANNOT be provided

  2. B

    The invocation of the downstream API will run to completion without timing out

  3. C

    A default timeout of 500 ms will automatically be applied by the Mule runtime in which the upstream
    API implementation executes

  4. D

    A toad-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the
    downstream API implementation executes

Show answer and explanation

Correct answer: A

Explanation

>> First thing first, the default HTTP response timeout for HTTP connector is 10000 ms (10 seconds). NOT
500 ms.

>> Mule runtime does NOT apply any such "load-dependent" timeouts. There is no such behavior currently
in Mule.

>> As there is default 10000 ms time out for HTTP connector, we CANNOT always guarantee that the invocation of the downstream API will run to completion without timing out due to its unreliable SLA times.
If the response time crosses 10 seconds then the request may time out.

The main impact due to this is that a proper SLA for the upstream API CANNOT be provided.

Question 5 Single choice

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?

  1. A

    Approve the client application request for the chosen SLA tier

  2. B

    Request access to the appropriate API Instances deployed to multiple environments using the client application's credentials

  3. C

    Modify the client application to call the API using the client application's credentials

  4. D
    Create a new application in Anypoint Exchange for requesting access to the API
Show answer and explanation

Correct answer: A

Explanation

>> Only approving the client application request for the chosen SLA tier can be automated

>> Rest of the provided options are not valid

Question 6 Single choice

An Order API triggers a sequence of other API calls to look up details of an order's items in a back-end inventory database. The Order API calls the OrderItems process API, which calls the Inventory system API. The Inventory system API performs database operations in the back-end inventory database.

The network connection between the Inventory system API and the database is known to be unreliable and hang at unpredictable times.

Where should a two-second timeout be configured in the API processing sequence so that the Order API never waits more than two seconds for a response from the Orderltems process API?

  1. A

    In the Orderltems process API implementation

  2. B

    In the Order API implementation

  3. C

    In the Inventory system API implementation

  4. D

    In the inventory database

Show answer and explanation

Correct answer: A

Question 7 Single choice

A European company has customers all across Europe, and the IT department is migrating from an older platform to MuleSoft. The main requirements are that the new platform should allow redeployments with zero downtime and deployment of applications to multiple runtime versions, provide security and speed, and utilize Anypoint MQ as the message service.

Which runtime plane should the company select based on the requirements without additional network configuration?

  1. A

    Runtime Fabric on VMs / Bare Metal for the runtime plane

  2. B

    Customer-hosted runtime plane

  3. C

    MuleSoft-hosted runtime plane (CloudHub)

  4. D

    Anypoint Runtime Fabric on Self-Managed Kubernetes for the runtime plane

Show answer and explanation

Correct answer: C

Question 8 Single choice

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

  1. A

    When it Is required to make ALL applications highly available across multiple data centers

  2. B

    When it is required that ALL APIs are private and NOT exposed to the public cloud

  3. C

    When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data

  4. D

    When ALL backend systems in the application network are deployed in the organization's intranet

Show answer and explanation

Correct answer: C

Explanation

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.
