Options:

A.

Database polling continues Only HTTP requests sent to the remaining node continue to be accepted

B.

Database polling stops All HTTP requests continue to be accepted

C.

Database polling continues All HTTP requests continue to be accepted, but requests to the failed node Incur increased latency

A Mule application is being designed for deployment to a single CloudHub worker. The Mule application will have a flow that connects to a SaaS system to perform some operations each time the flow is invoked.

The SaaS system connector has operations that can be configured to request a short-lived token (fifteen minutes) that can be reused for subsequent connections within the fifteen minute time window. After the token expires, a new token must be requested and stored.

What is the most performant and idiomatic (used for its intended purpose) Anypoint Platform component or service to use to support persisting and reusing tokens in the Mule application to help speed up reconnecting the Mule application to the SaaS application?

Options:

A.

Nonpersistent object store

B.

Persistent object store

C.

Variable

D.

Questions 12

When designing an upstream API and its implementation, the development team has been advised to not set timeouts when invoking downstream API. Because the downstream API has no SLA that can be relied upon. This is the only donwstream API dependency of that upstream API. Assume the downstream API runs uninterrupted without crashing. What is the impact of this advice?

Options:

A.

The invocation of the downstream API will run to completion without timing out.

B.

An SLA for the upstream API CANNOT be provided.

C.

A default timeout of 500 ms will automatically be applied by the Mule runtime in which the upstream API implementation executes.

D.

A load-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the downstream API implementation executes.

What Is a recommended practice when designing an integration Mule 4 application that reads a large XML payload as a stream?

Options:

A.

The payload should be dealt with as a repeatable XML stream, which must only be traversed (iterated-over) once and CANNOT be accessed randomly from DataWeave expressions and scripts

B.

The payload should be dealt with as an XML stream, without converting it to a single Java object (POJO)

C.

The payload size should NOT exceed the maximum available heap memory of the Mute runtime on which the Mule application executes

D.

The payload must be cached using a Cache scope If It Is to be sent to multiple backend systems

An organization has decided on a cloudhub migration strategy that aims to minimize the organizations own IT resources. Currently, the organizational has all of its Mule applications running on its own premises and uses an premises load balancer that exposes all APIs under the base URL https://api.acme.com

For each migrated Mule application, deploy an API proxy Mule application to Cloudhub with all applications under the control of a dedicated load balancer(CLB)

Update the CNAME record for api.acme.com in the organization DNS server pointing to the A record of a cloudhub dedicated load balancer(DLB)

Apply mapping rules in the DLB to map each API proxy application to its corresponding Mule applications

C.

Deploy the Mule applications to Cloudhub

Create CNAME record for api.acme.com in the Cloudhub Shared load balancer (SLB) pointing to the A record of the on-premise load balancer
