In IBM MQ, when designing a financial transaction processing system that must ensure every payment request message is processed exactly once without duplication, even in case of network interruptions or application crashes, which configuration is best suited to guarantee exactly-once delivery semantics?

• A.  Relying on operating system-level file logging instead of MQ persistence
• B.  Implementing persistent messaging with assured delivery and transaction coordination
• C.  Using non-persistent queues with application-side deduplication logic
• D.  Using publish/subscribe model with non-durable subscriptions for high speed

In IBM MQ, when setting up a highly available messaging environment across multiple servers, which of the following configurations ensures that messages are not lost even if one queue manager fails, while allowing continuous message flow to clients?

• A.  Implementing a distributed queue scenario with local queues on each server without any replication
• B.  Setting up a multi-instance queue manager where two instances share the same data path and automatically take over if the active instance fails
• C.  Configuring queue replication across multiple queue managers using MQ cluster channels without persistent storage
• D.  Using a single queue manager with client reconnection options enabled

When monitoring IBM MQ for performance and operational issues, which tool or interface provides the most detailed metrics including queue depth, channel status, and message rates, and can be used to script automated alerts?

• A.  MQSC commands executed manually on each queue manager
• B.  MQ's built-in performance events and statistics combined with PCF (Programmable Command Format) commands or REST API
• C.  MQ Explorer graphical interface only
• D.  Operating system-level monitoring of process CPU and memory usage

In IBM MQ, when configuring message channels between two queue managers over a network that may have intermittent connectivity issues, which setup ensures that messages are reliably delivered without loss, even if the network connection drops temporarily?

• A.  Using a Sender-Receiver channel pair with message persistence and retry intervals defined
• B.  Using non-persistent messages with standard channel settings
• C.  Using cluster-sender channels without confirming delivery
• D.  Configuring a client connection with automatic reconnect option enabled

In scenarios where a message cannot be processed due to an unexpected application error, which IBM MQ mechanism ensures that the message is safely returned to the queue and retried according to a defined policy, preventing loss or duplication of messages while maintaining processing efficiency?

• A.  Alias queue forwarding messages automatically
• B.  Temporary queue for manual retry
• C.  Dead-letter queue for undeliverable messages
• D.  Backout queue with a defined backout threshold
