An operations team is analyzing the effort needed to set up monitoring of their application network. They are looking at which API invocation metrics can be used to identify and predict trouble without having to write custom scripts or install additional analytics software or tools.
Which type of metrics can satisfy this goal of directly identifying and predicting failures?

• A.The number and types of API policy violations per day
• B.The effectiveness of the application network based on the level of reuse
• C.The number and types of past API invocations across the application network
• D.The ROI from each APT invocation

A developer is building a client application to invoke an API deployed to the STAGING environment that is governed by a client ID enforcement policy.
What is required to successfully invoke the API?

• A.The client ID and secret for the Anypoint Platform account owning the API in the STAGING environment
• B.The client ID and secret for the Anypoint Platform account's STAGING environment
• C.The client ID and secret obtained from Anypoint Exchange for the API instance in the STAGING environment
• D.A valid OAuth token obtained from Anypoint Platform and its associated client ID and secret

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?

• A.Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries
• B.Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete
• C.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
• D.Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds

A Platform Architect inherits a legacy monolithic SOAP-based web service that performs a number of tasks, including showing all policies belonging to a client. The service connects to two back-end systems - a life-insurance administration system and a general-insurance administration system - and then queries for insurance policy information within each system, aggregates the results, and presents a SOAP-based response to a user interface (UI).
The architect wants to break up the monolithic web service to follow API-led conventions.
Which part of the service should be put into the process layer?

• A.Presenting the SOAP-based response to the UI
• B.Querying the data from the administration systems
• C.Authenticating and maintaining connections to each of the back-end administration systems
• D.Combining the insurance policy information from the administration systems

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