質問 1：
A corporation has deployed multiple mule applications implementing various public and private API's to different cloudhub workers. These API's arc Critical applications that must be highly available and in line with the reliability SLA as defined by stakeholders.
How can API availability (liveliness or readiness) be monitored so that Ops team receives outage notifications?
A. Use any point functional monitoring test API's functional behavior
B. Configure alerts with failure conditions in runtime manager
C. Configure alerts failure conditions in API manager
D. Enable monitoring of individual applications from Anypoint monitoring

質問 2：
When a Mule application using VM queues is deployed to a customer-hosted cluster or multiple CloudHub v1.0 workers/replicas, how are messages consumed across the nodes?
A. Sequentially, only from the primary node
B. Round-robin, within an XA transaction
C. Sequentially, from a dedicated Anypoint MQ queue
D. In a non-deterministic way

質問 3：
Refer to the exhibit.

An organization uses a 2-node Mute runtime cluster to host one stateless API implementation. The API is accessed over HTTPS through a load balancer that uses round-robin for load distribution.
Two additional nodes have been added to the cluster and the load balancer has been configured to recognize the new nodes with no other change to the load balancer.
What average performance change is guaranteed to happen, assuming all cluster nodes are fully operational?
A. 100% increase in the throughput of the API
B. 50% reduction In the JVM heap memory consumed by each node
C. 50% reduction in the response time of the API
D. 50% reduction In the number of requests being received by each node
正解：D

質問 7：
A team would like to create a project skeleton that developers can use as a starting point when creating API Implementations with Anypoint Studio. This skeleton should help drive consistent use of best practices within the team.
What type of Anypoint Exchange artifact(s) should be added to Anypoint Exchange to publish the project skeleton?
A. a Mule application template with the key components and minimal integration logic
B. An example of an API implementation following best practices
C. A RAML archetype and reusable trait definitions to be reused across API implementations
D. A custom asset with the default API implementation
正解：A

質問 8：
An organization has several APIs that accept JSON data over HTTP POST. The APIs are all publicly available and are associated with several mobile applications and web applications. The organization does NOT want to use any authentication or compliance policies for these APIs, but at the same time, is worried that some bad actor could send payloads that could somehow compromise the applications or servers running the API implementations. What out-of-the-box Anypoint Platform policy can address exposure to this threat?
A. Apply a Header injection and removal policy that detects the malicious data before it is used
B. Shut out bad actors by using HTTPS mutual authentication for all API invocations
C. Apply a JSON threat protection policy to all APIs to detect potential threat vectors
D. Apply an IP blacklist policy to all APIs; the blacklist will Include all bad actors
