Question 1

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?

A : When the API is invoked by an unrecognized API client

B : When a particular API client invokes the API too often within a given time period

C : When the response time of API invocations exceeds a threshold

D : When the API receives a very high number of API invocations

Answer: C

Question 2

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?

A : 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

B : 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

C : Implement an anti-corruption layer in the Order API that transforms the Product API data model into internal data types of the Order API

D : 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

Answer: C

Question 3

Refer to the exhibit. 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 changesB) One set of APIs (Experience API, Process API, and System API) for the web app, and another set for the mobile appC) 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 systemD) 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

A : Option A

B : Option B

C : Option C

D : Option D

Answer: C

Question 4

An eCommerce company is adding a new Product Details feature to their website, A customer will launch theproduct catalog page, a new Product Details link willappear by product where they can click to retrieve the product detail description. Product detail data isupdated with product update releases, once or twice a year, Presentlythe database response time has been very slow due to high volume.What action retrieves the product details with the lowest response time, fault tolerant, and consistent data?

A : Select the product details from a database in a Cache scope and return them within the API response

B : Select the product details from a database and put them in Anypoint MQ; the Anypoint MO subseriber will receive the product details and return them within the API response

C : Use an object store to store and retrieve the product details originally read from a database and return them within the API response

D : Select the product details from a database and return them within the API response

Answer: C

Question 5

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

Answer: B
