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

What are 4 important Platform Capabilities offered by Anypoint Platform?

Options :

A : API Versioning, API Runtime Execution and Hosting, API Invocation, API Consumer Engagement

B : API Design and Development, API Runtime Execution and Hosting, API Versioning, API Deprecation

C : API Design and DevelopAPI Design and Development, API Deprecation, API Versioning, API Consumer Engagement ment, API Runtime Execution and Hosting, API Operations and Management, API Consumer Engagement

D : API Design and Development, API Deprecation, API Versioning, API Consumer Engagement

Answer: C

Question 3

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 4

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?

Options :

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

Answer: A

Question 5

An application updates an inventory running only one process at any given time to keep the inventoryconsistent. This process takes 200 milliseconds (.2 seconds) toexecute; therefore, the scalability threshold of the application is five requests per second.What is the impact on the application if horizontal scaling is applied, thereby increasing the number of Muleworkers?

Options :

A : The application scalability threshold is five requests per second regardless of the horizontal scaling

B : The total process execution time is now 100 milliseconds (.1 seconds)

C : The application scalability threshold is now 10 requests per second

D : Horizontal scaling cannot be applied to an already-running application
