An organization has several APIs that accept JSON data over HTTP POST. The APIs are all publicly available and are associated with several mobile applications and web applications.The organization does NOT want to use any authentication or compliance policies for these APIs, but at the same time, is worried that some bad actor could send payloads that could somehow compromise the applications or servers running the API implementations.What out-of-the-box Anypoint Platform policy can address exposure to this threat?

• Shut out bad actors by using HTTPS mutual authentication for all API invocations
  
• Apply an IP blacklist policy to all APIs; the blacklist will Include all bad actors
  
• Apply a Header injection and removal policy that detects the malicious data before it is used
  
• Apply a JSON threat protection policy to all APIs to detect potential threat vectors
  

An API implementation is deployed to CloudHub.What conditions can be alerted on using the default Anypoint Platform functionality, where the alert conditions depend on the end-to-end request processing of the API implementation?

• When the API is invoked by an unrecognized API client
  
• When a particular API client invokes the API too often within a given time period
  
• When the response time of API invocations exceeds a threshold
  
• When the API receives a very high number of API invocations
  

Version 3.0.1 of a REST API implementation represents time values in PST time using ISO 8601 hh:mm:ss format. The API implementation needs to be changed to instead represent time values in CEST time using ISO 8601 hh:mm:ss format. When following the semver.org semantic versioning specification, what version should be assigned to the updated API implementation?

• 3.0.2
  
• 4.0.0
  
• 3.1.0
  
• 3.0.1
  

A code-centric API documentation environment should allow API consumers to investigate and execute API client source code that demonstrates invoking one or more APIs as part of representative scenarios.What is the most effective way to provide this type of code-centric API documentation environment using Anypoint Platform?

• Enable mocking services for each of the relevant APIs and expose them via their Anypoint Exchange entry
  
• Ensure the APIs are well documented through their Anypoint Exchange entries and API Consoles and share these pages with all API consumers
  
• Create API Notebooks and include them in the relevant Anypoint Exchange entries
  
• Make relevant APIs discoverable via an Anypoint Exchange entry
  

An Order API must be designed that contains significant amounts of integration logic and involves the invocation of the Product API.The power relationship between Order API and Product API is one of 'Customer/Supplier', because the Product API is used heavily throughout the organization and is developed by a dedicated development team located in the office of the CTO.What strategy should be used to deal with the API data model of the Product API within the Order API?

• Convince the development team of the Product API to adopt the API data model of the Order API such that the integration logic of the Order API can work with one consistent internal data model
  
• Work with the API data types of the Product API directly when implementing the integration logic of the Order API such that the Order API uses the same (unchanged) data types as the Product API
  
• Implement an anti-corruption layer in the Order API that transforms the Product API data model into internal data types of the Order API
  
• Start an organization-wide data modeling initiative that will result in an Enterprise Data Model that will then be used in both the Product API and the Order API
  

What is a key performance indicator (KPI) that measures the success of a typical C4E that is immediately apparent in responses from the Anypoint Platform APIs?

• The number of production outage incidents reported in the last 24 hours
  
• The number of API implementations that have a publicly accessible HTTP endpoint and are being managed by Anypoint Platform
  
• The fraction of API implementations deployed manually relative to those deployed using a CI/CD tool
  
• The number of API specifications in RAML or OAS format published to Anypoint Exchange
  

How are an API implementation, API client, and API consumer combined to invoke and process an API?

• The API consumer creates an API implementation, which receives API invocations from an API such that they are processed for an API client
  
• The API client creates an API consumer, which receives API invocations from an API such that they are processed for an API implementation
  
• The ApI consumer creates an API client, which sends API invocations to an API such that they are processed by an API implementation
  
• The ApI client creates an API consumer, which sends API invocations to an API such that they are processed by an API implementation
  

An organization is implementing a Quote of the Day API that caches today's quote.What scenario can use the GoudHub Object Store via the Object Store connector to persist the cache's state?

• When there are three CloudHub deployments of the API implementation to three separate CloudHub regions that must share the cache state
  
• 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
  
• When there is one deployment of the API implementation to CloudHub and anottV deployment to a customer-hosted Mule runtime that must share the cache state
  
• When there is one CloudHub deployment of the API implementation to three CloudHub workers that must share the cache state
  

A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity.The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms.If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?

• Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries
  
• Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete
  
• No timeout is possible to meet the upstream API's desired SLA; a different SLA must be negotiated with the first downstream API or invoke an alternative API
  
• Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds
  

What correctly characterizes unit tests of Mule applications?

• They test the validity of input and output of source and target systems
  
• They must be run in a unit testing environment with dedicated Mule runtimes for the environment
  
• They must be triggered by an external client tool or event source
  
• They are typically written using MUnit to run in an embedded Mule runtime that does not require external connectivity
