what is true when using customer-hosted Mule runtimes with the MuleSoft-hosted Anypoint Platform control plane (hybrid deployment)?

• A.Anypoint Runtime Manager initiates a network connection to a Mule runtime in order to deploy Mule applications
• B.The MuleSoft-hosted Shared Load Balancer can be used to load balance API invocations to the Mule runtimes
• C.API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane
• D.Anypoint Runtime Manager automatically ensures HA in the control plane by creating a new Mule runtime instance in case of a node failure

Correct Answer: C

Correct answer: API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane.
*****************************************
>> We CANNOT use Shared Load balancer to load balance APIs on customer hosted runtimes

>> For Hybrid deployment models, the on-premises are first connected to Runtime Manager using Runtime Manager agent. So, the connection is initiated first from On-premises to Runtime Manager. Then all control can be done from Runtime Manager.
>> Anypoint Runtime Manager CANNOT ensure automatic HA. Clusters/Server Groups etc should be configured before hand.
Only TRUE statement in the given choices is, API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane. There are several references below to justify this statement.

A RAML definition has been proposed for a new Promotions Process API, and has been published to Anypoint Exchange.
The Marketing Department, who will be an important consumer of the Promotions API, has important requirements and expectations that must be met.
What is the most effective way to use Anypoint Platform features to involve the Marketing Department in this early API design phase?
A) Ask the Marketing Department to interact with a mocking implementation of the API using the automatically generated API Console

B) Organize a design workshop with the DBAs of the Marketing Department in which the database schema of the Marketing IT systems is translated into RAML

C) Use Anypoint Studio to Implement the API as a Mule application, then deploy that API implementation to CloudHub and ask the Marketing Department to interact with it

D) Export an integration test suite from API designer and have the Marketing Department execute the tests In that suite to ensure they pass

• A.Option B
• B.Option A
• C.Option C
• D.Option D

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.Configure a "worker not responding" alert in Anypoint Runtime Manager.
• B.Handle API invocation exceptions within the calling API client and raise an alert from that API client when the API is unavailable.
• C.Implement a heartbeat/health check within the API and invoke it from outside the Anypoint Platform and alert when the heartbeat does not respond.
• D.Create an alert for when the API receives no requests within a specified time period.

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.Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds
• B.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
• C.Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries
• D.Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete

An organization makes a strategic decision to move towards an IT operating model that emphasizes consumption of reusable IT assets using modern APIs (as defined by MuleSoft).
What best describes each modern API in relation to this new IT operating model?

• A.Each modern API must be easy to consume, so should avoid complex authentication mechanisms such as SAML or JWT D
• B.Each modern API has its own software development lifecycle, which reduces the need for documentation and automation
• C.Each modern API must be REST and HTTP based
• D.Each modem API must be treated like a product and designed for a particular target audience (for instance, mobile app developers)
