Question 1

In which layer of API-led connectivity, does the business logic orchestration reside?

Options :

A : System Layer

B : Experience Layer

C : Process Layer

Answer: C

Question 2

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?

Options :

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

Question 3

An API implementation is being designed that must invoke an Order API, which is known to repeatedly experience downtime. For this reason, a fallback API is to be called when the Order API is unavailable. What approach to designing the invocation of the fallback API provides the best resilience?

Options :

A : Search Anypoint Exchange for a suitable existing fallback API, and then implement invocations to this fallback API in addition to the Order API

B : Create a separate entry for the Order API in API Manager, and then invoke this API as a fallback API if the primary Order API is unavailable

C : Redirect client requests through an HTTP 307 Temporary Redirect status code to the fallback API whenever the Order API is unavailable

D : Set an option in the HTTP Requester component that invokes the Order API to instead invoke a fallback API whenever an HTTP 4xx or 5xx response status code is returned from the Order API

Answer: A

Question 4

Which two statements are true about the technology architecture of an Anypoint Virtual Private Cloud(VPC)?Choose 2 answers

Options :

A : Ports 8081 and 8082 are used

B : CIDR blacks are used

C : Anypoint VPC is responsible for load balancing the applications

D : Round-robin load balancing is used to distribute client requests across different applications

E : By default, HTTP requests can be made from the public internet to workers at port 6091

Answer: B,E

Question 5

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

Options :

A : Option A

B : Option B

C : Option C

D : Option D
