• Question 123:

  An organization designing a hybrid, load balanced, single cluster production environment. Due to performance service level agreement goals, it is looking into running the Mule applications in an active-active multi node cluster configuration.

  What should be considered when running its Mule applications in this type of environment?

  A. All event sources, regardless of time , can be configured as the target source by the primary node in the cluster

  B. An external load balancer is required to distribute incoming requests throughout the cluster nodes

  C. A Mule application deployed to multiple nodes runs in an isolation from the other nodes in the cluster

  D. Although the cluster environment is fully installed configured and running, it will not process any requests until an outage condition is detected by the primary node in the cluster.

  Correct Answer: B

• Question 124:

  An organization is creating a set of new services that are critical for their business. The project team prefers using REST for all services but is willing to use SOAP with common WS-" standards if a particular service requires it.

  What requirement would drive the team to use SOAP/WS-* for a particular service?

  A. Must use XML payloads for the service and ensure that it adheres to a specific schema

  B. Must publish and share the service specification (including data formats) with the consumers of the service

  C. Must support message acknowledgement and retry as part of the protocol

  D. Must secure the service, requiring all consumers to submit a valid SAML token

  Correct Answer: D

  Security Assertion Markup Language (SAML) is an open standard that allows identity providers (IdP) to pass authorization credentials to service providers (SP). SAML transactions use Extensible Markup Language (XML) for standardized

  communications between the identity provider and service providers. SAML is the link between the authentication of a user's identity and the authorization to use a service.

  WS-Security is the key extension that supports many authentication models including:

  basic username/password credentials, SAML, OAuth and more. A common way that SOAP API's are authenticated is via SAML Single Sign On (SSO). SAML works by facilitating the exchange of authentication and authorization credentials

  across applications. However, there is no specification that describes how to add SAML to REST web services.

• Question 125:

  An organization needs to enable access to their customer data from both a mobile app and a web application, which each need access to common fields as well as certain unique fields. The data is available partially in a database and partially in a 3rd-party CRM system. What APIs should be created to best fit these design requirements?

  

  A. A Process API that contains the data required by both the web and mobile apps, allowing these applications to invoke it directly and access the data they need thereby providing the flexibility to add more fields in the future without needing API changes.

  B. One set of APIs (Experience API, Process API, and System API) for the web app, and another set for the mobile app.

  C. Separate Experience APIs for the mobile and web app, but a common Process API that invokes separate System APIs created for the database and CRM system

  D. A common Experience API used by both the web and mobile apps, but separate Process APIs for the web and mobile apps that interact with the database and the CRM System.

  Correct Answer: C

  Lets analyze the situation in regards to the different options available Option : A common Experience API but separate Process APIs Analysis : This solution will not work because having common experience layer will not help the purpose as mobile and web applications will have different set of requirements which cannot be fulfilled by single experience layer API Option : Common Process API Analysis : This solution will not work because creating a common process API will impose limitations in terms of flexibility to customize API;s as per the requirements of different applications. It is not a recommended approach. Option : Separate set of API's for both the applications Analysis : This goes against the principle of Anypoint API-led connectivity approach which promotes creating reusable assets. This solution may work but this is not efficient solution and creates duplicity of code. Hence the correct answer is: Separate Experience APIs for the mobile and web app, but a common Process API that invokes separate System APIs created for the database and CRM system

• Question 126:

  An organization has decided on a cloudhub migration strategy that aims to minimize the organizations own IT resources. Currently, the organizational has all of its Mule applications running on its own premises and uses an premises load balancer that exposes all APIs under the base URL https://api.acme.com As part of the migration strategy, the organization plans to migrate all of its Mule applications and load balancer to cloudhub What is the most straight-forward and cost effective approach to the Mule applications deployment and load balancing that preserves the public URLs?

  A. Deploy the Mule applications to Cloudhub Update the CNAME record for an api.acme.com in the organizations DNS server pointing to the A record of a cloudhub dedicated load balancer(DLB) Apply mapping rules in the DLB to map URLs to their corresponding Mule applications

  B. For each migrated Mule application, deploy an API proxy Mule application to Cloudhub with all applications under the control of a dedicated load balancer(CLB) Update the CNAME record for api.acme.com in the organization DNS server pointing to the A record of a cloudhub dedicated load balancer(DLB) Apply mapping rules in the DLB to map each API proxy application to its corresponding Mule applications

  C. Deploy the Mule applications to Cloudhub Create CNAME record for api.acme.com in the Cloudhub Shared load balancer (SLB) pointing to the A record of the on-premise load balancer Apply mapping rules in the SLB to map URLs to their corresponding Mule applications

  D. Deploy the Mule applications to Cloudhub Update the CNAME record for api.acme.com in the organization DNS server pointing to the A record of the cloudhub shared load balancer(SLB) Apply mapping rules in the SLB to map URLs to their corresponding Mule applications.

• Question 127:

  Which Exchange asset type represents a complete API specification in RAML or OAS format?

  A. Connectors

  B. REST APIs

  C. API Spec Fragments

  D. SOAP APIs

  Correct Answer: B

• Question 128:

  A mule application is being designed to perform product orchestration. The Mule application needs to join together the responses from an inventory API and a Product Sales History API with the least latency. To minimize the overall latency. What is the most idiomatic (used for its intended purpose) design to call each API request in the Mule application?

  A. Call each API request in a separate lookup call from Dataweave reduce operator

  B. Call each API request in a separate route of a Scatter-Gather

  C. Call each API request in a separate route of a Parallel For Each scope

  D. Call each API request in a separate Async scope

  Correct Answer: B

  Scatter-Gather sends a request message to multiple targets concurrently. It collects the responses from all routes, and aggregates them into a single message. Reference: https://docs.mulesoft.com/mule-runtime/4.3/scatter- gather-concept

• Question 129:

  A corporation has deployed multiple mule applications implementing various public and private API's to different cloudhub workers. These API's arc Critical applications that must be highly available and in line with the reliability SLA as defined by stakeholders.

  How can API availability (liveliness or readiness) be monitored so that Ops team receives outage notifications?

  A. Enable monitoring of individual applications from Anypoint monitoring

  B. Configure alerts with failure conditions in runtime manager

  C. Configure alerts failure conditions in API manager

  D. Use any point functional monitoring test API's functional behavior

  Correct Answer: A

• Question 130:

  What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST API's, Anypoint CLI or the Mule Maven plugin?

  A. By default, the Anypoint CLI and Mule Maven plugin are not included in the Mule runtime

  B. Access to Anypoint Platform API;s and Anypoint CLI can be controlled separately thruough the roles and permissions in Anypoint platform, so that specific users can get access to Anypoint CLI while others get access to the platform API's

  C. Anypoint Platform API's can only automate interactions with CloudHub while the Mule maven plugin is required for deployment to customer hosted Mule runtimes

  D. API policies can be applied to the Anypoint platform API's so that only certain LOS's has access to specific functions

  Correct Answer: A

  Correct answer is By default, the Anypoint CLI and Mule Maven plugin are not included in the Mule runtime Maven is not part of runtime though it is part of studio. You do not need it to deploy in order to deploy your app. Same is the case with

  CLI.
