NEW QUESTION 43
Refer to the exhibit. This Mule application is deployed to multiple CloudHub workers with persistent queues enabled.
The retrieveFile flow's event source reads a CSV file from a remote SFTP server and then publishes each record in the CSV file to a VM queue.
The processCustomerRecords flow's VM Listener receives messages from the same VM queue and then processes each message separately.
How are messages routed to the CloudHub workers as messages are received by the VM Listener?
- A. Each message is duplicated to ALL of the CloudHub workers, thereby SHARING EACH message with ALL the CloudHub workers
- B. Each message is routed to the SAME CloudHub worker that retrieved the file, thereby BINDING ALL messages to ONLY that ONE CloudHub worker
- C. Each message is routed to ONE of the CloudHub workers in a DETERMINISTIC round-robin fashion, thereby EXACTLY BALANCING messages among the CloudHub workers
- D. Each message is routed to ONE of the available CloudHub workers in a NON-DETERMINISTIC non-round- robin fashion, thereby APPROXIMATELY BALANCING messages among the CloudHub workers
Answer: D
NEW QUESTION 44
Refer to the exhibit. A business process involves two APIs that interact with each other asynchronously over HTTP. Each API is implemented as a Mule application. API 1 receives the initial HTTP request and invokes API 2 (in a fire and forget fashion) while API 2, upon completion of the processing, calls back into API 1 to notify about completion of the asynchronous process.
Each API is deployed to multiple redundant Mule runtimes and a separate load balancer, and is deployed to a separate network zone.
In the network architecture, how must the firewall rules be configured to enable the above interaction between API 1 and API 2?
- A. To allow communication between the load balancers used by each API
- B. To authorize the certificates used by both the APIs
- C. To enable communication from each API's Mule runtimes and network zone to the load balancer of the other API

NEW QUESTION 52
Refer to the exhibit.
A shopping cart checkout process consists of a web store backend sending a sequence of API invocations to an Experience API, which in turn invokes a Process API. All API invocations are over HTTPS POST. The Java web store backend executes in a Java EE application server, while all API implementations are Mule applications executing in a customer -hosted Mule runtime.
End-to-end correlation of all HTTP requests and responses belonging to each individual checkout Instance is required. This is to be done through a common correlation ID, so that all log entries written by the web store backend, Experience API implementation, and Process API implementation include the same correlation ID for all requests and responses belonging to the same checkout instance.
What is the most efficient way (using the least amount of custom coding or configuration) for the web store backend and the implementations of the Experience API and Process API to participate in end-to-end correlation of the API invocations for each checkout instance?
A)
The web store backend, being a Java EE application, automatically makes use of the thread-local correlation ID generated by the Java EE application server and automatically transmits that to the Experience API using HTTP-standard headers No special code or configuration is included in the web store backend, Experience API, and Process API implementations to generate and manage the correlation ID
B)
The web store backend generates a new correlation ID value at the start of checkout and sets it on the X-CORRELATlON-lt HTTP request header In each API invocation belonging to that checkout No special code or configuration is included in the Experience API and Process API implementations to generate and manage the correlation ID
C)
The Experience API implementation generates a correlation ID for each incoming HTTP request and passes it to the web store backend in the HTTP response, which includes it in all subsequent API invocations to the Experience API.
The Experience API implementation must be coded to also propagate the correlation ID to the Process API in a suitable HTTP request header
D)
The web store backend sends a correlation ID value in the HTTP request body In the way required by the Experience API The Experience API and Process API implementations must be coded to receive the custom correlation ID In the HTTP requests and propagate It in suitable HTTP request headers
