Demo Questions

  2. Client ID enforcement
  3. Rate limiting
  4. JSON threat protection
Correct answer: A

Question 2
An organization is implementing a Quote of the Day API that caches today's quote. 
What scenario can use the CloudHub Object Store via the Object Store connector to persist the cache's state?
  1. When there are three CloudHub deployments of the API implementation to three separate CloudHub regions that must share the cache state.
  2. When there are two CloudHub deployments of the API implementation by two Anypoint Platform business groups to the same CloudHub region that must share the cache state.
  3. When there is one deployment of the API implementation to CloudHub and another deployment to a customer-hosted Mule runtime that must share the cache state.
  4. When there is one CloudHub deployment of the API implementation to three CloudHub workers that must share the cache state.
Correct answer: C
Question 3
What condition requires using a CloudHub Dedicated Load Balancer?
  1. When cross-region load balancing is required between separate deployments of the same Mule application
  2. When custom DNS names are required for API implementations deployed to customer-hosted Mule runtimes
  3. When API invocations across multiple CloudHub workers must be load balanced
  4. When server-side load-balanced TLS mutual authentication is required between API implementations and API clients
Correct answer: B
Question 4
What do the API invocation metrics provided by Anypoint Platform provide?
  1. ROI metrics from APIs that can be directly shared with business users
  2. Measurements of the effectiveness of the application network based on the level of reuse
  3. Data on past API invocations to help identify anomalies and usage patterns across various APIs
  4. Proactive identification of likely future policy violations that exceed a given threat threshold
Correct answer: B

Question 5
An API implementation is deployed on a single worker on CloudHub and invoked by external API clients (outside of CloudHub). 
How can an alert be set up that is guaranteed to trigger AS SOON AS that API implementation stops responding to API invocations?
  1. Implement a heartbeat/health check within the API and invoke it from outside the Anypoint Platform and alert when the heartbeat does not respond.
  2. Configure a “worker not responding” alert in Anypoint Runtime Manager.
  3. Handle API invocation exceptions within the calling API client and raise an alert from that API client when the API is unavailable.
  4. Create an alert for when the API receives no requests within a specified time period.
Correct answer: D
Question 6
The implementation of a Process API must change. 
What is a valid approach that minimizes the impact of this change on API clients?
  1. Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition.
  2. Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version.
  3. Implement required changes to the Process API implementation so that, whenever possible, the Process API's RAML definition remains unchanged.
  4. Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanently to inform API clients they should be calling the new API implementation.
Correct answer: A
Question 7
In an organization, the InfoSec team is investigating Anypoint Platform related data traffic. 
From where does most of the data available to Anypoint Platform for monitoring and alerting originate?
  1. From the Mule runtime or the API implementation, depending on the deployment model
  2. From various components of Anypoint Platform, such as the Shared Load Balancer, VPC, and Mule runtimes
  3. From the Mule runtime or the API Manager, depending on the type of data
  4. From the Mule runtime irrespective of the deployment model
Correct answer: B
Question 8
A System API is designed to retrieve data from a backend system that has scalability challenges. 
What API policy can best safeguard the backend system?
  1. IP whitelist
  2. SLA-based rate limiting
  3. OAuth 2 token enforcement
  4. Client ID enforcement
Correct answer: A

Question 9
Refer to the exhibit. 
  
What is a valid API in the sense of API-led connectivity and application networks?
  1. Java RMI over TCP 
      
  2. XML over HTTP 
      
  3. CORBA over IIОР 
      
  4. XML over UDP 
      
Correct answer: B
Question 10
When using CloudHub with the Shared Load Balancer, what is managed EXCLUSIVELY by the API implementation (the Mule application) and NOT by Anypoint Platform?
  1. The assignment of each HTTP request to a particular CloudHub worker
  2. The logging configuration that enables log entries to be visible in Runtime Manager
  3. The SSL certificates used by the API implementation to expose HTTPS endpoints
  4. The number of DNS entries allocated to the API implementation
