Question # 4

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%

Question # 12

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.

Question # 22

A system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. A process API is a client to the system API and is being rate limited by the system API, with different limits in each of the environments.
