Question # 8

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?

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

Question # 9

The implementation of a Process API must change.

What is a valid approach that minimizes the impact of this change on API clients?

A.

Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition

B.

Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version

C.

Implement required changes to the Process API implementation so that whenever possible, the Process API's RAML definition remains unchanged

D.

Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanently to inform API clients they should be calling the new API implementation

Question # 11

What Mule application deployment scenario requires using Anypoint Platform Private Cloud Edition or Anypoint Platform for Pivotal Cloud Foundry?

A.

When it Is required to make ALL applications highly available across multiple data centers

B.

When it is required that ALL APIs are private and NOT exposed to the public cloud

C.

When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data

Question # 12

What best describes the Fully Qualified Domain Names (FQDNs), also known as DNS entries, created when a Mule application is deployed to the CloudHub Shared Worker Cloud?

A.

A fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design

B.

The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region

C.

The FQDNs are determined by the application name, but can be modified by an administrator after deployment

D.

The FQDNs are determined by both the application name and the Anypoint Platform organization

Question # 13

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.

Shut out bad actors by using HTTPS mutual authentication for all API invocations

B.

Apply an IP blacklist policy to all APIs; the blacklist will Include all bad actors

C.

Apply a Header injection and removal policy that detects the malicious data before it is used

D.

Apply a JSON threat protection policy to all APIs to detect potential threat vectors

Question # 14

An API implementation is deployed on a single worker on CloudHub and invoked by external API clients (outside of CloudHub). How can an alert be set up that is guaranteed to trigger AS SOON AS that API implementation stops responding to API invocations?

A.

Implement a heartbeat/health check within the API and invoke it from outside the Anypoint Platform and alert when the heartbeat does not respond

B.

Configure a "worker not responding" alert in Anypoint Runtime Manager

C.

Handle API invocation exceptions within the calling API client and raise an alert from that API client when the API Is unavailable

D.

Create an alert for when the API receives no requests within a specified time period
