Question 1

Question 10: Skipped

An API implementation returns three X-RateLimit-* HTTP response headers to a requesting API client. What

type of information do these response headers indicate to the API client?

A : The error codes that result from throttling

B : A correlation ID that should be sent in the next request

C : The HTTP response size

D : The remaining capacity allowed by the API implementation

Answer: D

Question 2

Refer to the exhibit.

What is a valid API in the sense of API-led connectivity and application networks?

A : Java RMI over TCP

B : Java RMI over TCP

C : CORBA over HOP

D : XML over UDP

Answer: D

Question 3

A retail company is using an Order API to accept new orders. The Order API uses a JMS queue to submit orders to a backend order management service. The normal load for orders is being handled using two (2) CloudHub workers, each configured with 0.2 vCore. The CPU load of each CloudHub worker normally runs well below 70%. However, several times during the year the Order API gets four times (4x) the average number of orders. This causes the CloudHub worker CPU load to exceed 90% and the order submission time to exceed 30 seconds. The cause, however, is NOT the backend order management service, which still responds fast enough to meet the response SLA for the Order API. What is the MOST resource-efficient way to configure the Mule application's CloudHub deployment to help the company cope with this performance challenge?

A : Permanently increase the size of each of the two (2) CloudHub workers by at least four times (4x) to one (1) vCore

B : Use a vertical CloudHub autoscaling policy that triggers on CPU utilization greater than 70%

C : Permanently increase the number of CloudHub workers by four times (4x) to eight (8) CloudHub workers

D : Use a horizontal CloudHub autoscaling policy that triggers on CPU utilization greater than 70%

Answer: D

Question 4

What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST APIs, Anypoint CU, or the Mule Maven plugin?

A : Access to Anypoint Platform APIs and Anypoint CU can be controlled separately through the roles and permissions in Anypoint Platform, so that specific users can get access to Anypoint CLI white others get access to the platform APIs

B : Anypoint Platform APIs can ONLY automate interactions with CloudHub, while the Mule Maven plugin is required for deployment to customer-hosted Mule runtimes

C : By default, the Anypoint CLI and Mule Maven plugin are NOT included in the Mule runtime, so are NOT available to be used by deployed Mule applications

D : API policies can be applied to the Anypoint Platform APIs so that ONLY certain LOBs have access to specific functions

Answer: C

Question 5

Traffic is routed through an API proxy to an API implementation. The API proxy is managed by API Manager and the API implementation is deployed to a CloudHub VPC using Runtime Manager. API policies have been applied to this API. In this deployment scenario, at what point are the API policies enforced on incoming API client requests?

A : At the API proxy

B : At the API implementation

C : At both the API proxy and the API implementation

D : At a MuleSoft-hosted load balancer
