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

What Anypoint Connectors support transactions?

• Database, JMS, VM
• Database, 3MS, HTTP
• Database, JMS, VM, SFTP
• Database, VM, File

What is a key requirement when using an external Identity Provider for Client Management in Anypoint Platform?

• Single sign-on is required to sign in to Anypoint Platform
• The application network must include System APIs that interact with the Identity Provider
• To invoke OAuth 2.0-protected APIs managed by Anypoint Platform, API clients must submit access tokens issued by that same Identity Provider
• APIs managed by Anypoint Platform must be protected by SAML 2.0 policies

A retail company with thousands of stores has an API to receive data about purchases and insert it into a single database. Each individual store sends a batch of purchase data to the API about every 30 minutes. The API implementation uses a database bulk insert command to submit all the purchase data to a database using a custom JDBC driver provided by a data analytics solution provider. The API implementation is deployed to a single CloudHub worker. The JDBC driver processes the data into a set of several temporary disk files on the CloudHub worker, and then the data is sent to an analytics engine using a proprietary protocol. This process usually takes less than a few minutes. Sometimes a request fails. In this case, the logs show a message from the JDBC driver indicating an out-of-file-space message. When the request is resubmitted, it is successful. What is the best way to try to resolve this throughput issue?

• se a CloudHub autoscaling policy to add CloudHub workers
• Use a CloudHub autoscaling policy to increase the size of the CloudHub worker
• Increase the size of the CloudHub worker(s)
• Increase the number of CloudHub workers

An organization is deploying their new implementation of the OrderStatus System API to multiple workers in CloudHub. This API fronts the organization's on-premises Order Management System, which is accessed by the API implementation over an IPsec tunnel. What type of error typically does NOT result in a service outage of the OrderStatus System API?

• A CloudHub worker fails with an out-of-memory exception
• API Manager has an extended outage during the initial deployment of the API implementation
• The AWS region goes offline with a major network failure to the relevant AWS data centers
• The Order Management System is Inaccessible due to a network outage in the organization's on-premises data center

An API client calls one method from an existing API implementation. The API implementation is later updated. What change to the API implementation would require the API client's invocation logic to also be updated?

• When the data type of the response is changed for the method called by the API client
• When a new method is added to the resource used by the API client
• When a new required field is added to the method called by the API client
• When a child method is added to the method called by the API client

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 best practice when building System APIs?

• Document the API using an easily consumable asset like a RAML definition
• Model all API resources and methods to closely mimic the operations of the backend system
• Build an Enterprise Data Model (Canonical Data Model) for each backend system and apply it to System APIs
• Expose to API clients all technical details of the API implementation's interaction wifch the backend system

What is true about API implementations when dealing with legal regulations that require all data processing to be performed within a certain jurisdiction (such as in the USA or the EU)?

• They must avoid using the Object Store as it depends on services deployed ONLY to the US East region
• They must use a Jurisdiction-local external messaging system such as Active MQ rather than Anypoint MQ
• They must te deployed to Anypoint Platform runtime planes that are managed by Anypoint Platform control planes, with both planes in the same Jurisdiction
• They must ensure ALL data is encrypted both in transit and at rest

A Mule application exposes an HTTPS endpoint and is deployed to the CloudHub Shared Worker Cloud. All traffic to that Mule application must stay inside the AWS VPC. To what TCP port do API invocations to that Mule application need to be sent?

• 443
• 8081
• 8091
