Question 1

A large lending company has developed an API to unlock data from a database server and web server. TheAPI has been deployed to Anypoint Virtual Private Cloud(VPC) on CloudHub 1.0.The database server and web server are in the customer's secure network and are not accessible through thepublic internet. The database server is in the customer's AWSVPC, whereas the web server is in the customer's on-premises corporate data center.How can access be enabled for the API to connect with the database server and the web server?

Options :

A : Set up VPC peering with AWS VPC and a VPN tunnel to the customer-s on-premises corporate data center

B : Set up VPC peering with AWS VPC and the customer-s on-premises corporate data center

C : Setup a transit gateway to the customer-s on-premises corporate data center through AWS VPC

D : Set up VPC peering with the customer-s on-premises corporate data center and a VPN tunnel to AWS VPC

Answer: A

Question 2

Mule applications that implement a number of REST APIs are deployed to their own subnet that is inaccessible from outside the organization. External business-partners need to access these APIs, which are only allowed to be invoked from a separate subnet dedicated to partners - called Partner-subnet. This subnet is accessible from the public internet, which allows these external partners to reach it. Anypoint Platform and Mule runtimes are already deployed in Partner-subnet. These Mule runtimes can already access the APIs. What is the most resource-efficient solution to comply with these requirements, while having the least impact on other applications that are currently using the APIs?

Options :

A : Implement (or generate) an API proxy Mule application for each of the APIs, then deploy the API proxies to the Mule runtimes

B : Redeploy the API implementations to the same servers running the Mule runtimes

C : Add an additional endpoint to each API for partner-enablement consumption

D : Duplicate the APIs as Mule applications, then deploy them to the Mule runtimes

Answer: A

Question 3

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?

Options :

A : The number of production outage incidents reported in the last 24 hours

B : The number of API implementations that have a publicly accessible HTTP endpoint and are being managed by Anypoint Platform

C : The number of API specifications in RAML or OAS format published to Anypoint Exchange

Answer: C

Question 4

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 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?

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
