AZ-204 – Question 92

You implement Azure Service Bus to publish alarms. Each alarm controller uses Azure Service Bus to receive alarm signals as part of a transaction. Alarm events must be recorded for audit purposes. Each transaction record must include information about the alarm type that was activated.

You need to implement a reply trail auditing solution.
Which two actions should you perform? Each correct answer resents part of the solution.
NOTE: Each correct selection is worth one point.

B. Assign the value of the hazard message MessageId property to the DevileryCount property.

C. Assign the value of the hazard message SessionID property to the SequenceNumber property.

E. Assign the value of the hazard message SequenceNumber property to the DeliveryCount property.

F. Assign the value of the hazard message MessageId property to the SequenceNumber property.

D: CorrelationId: Enables an application to specify a context for the message for the purposes of correlation; for example, reflecting the MessageId of a message that is being replied to.

A: ReplyToSessionId: This value augments the ReplyTo information and specifies which SessionId should be set for the reply when sent to the reply entity.

Incorrect Answers:

B, E: DeliveryCount –

Number of deliveries that have been attempted for this message. The count is incremented when a message lock expires, or the message is explicitly abandoned by the receiver. This property is read-only.

C, E: SequenceNumber –

The sequence number is a unique 64-bit integer assigned to a message as it is accepted and stored by the broker and functions as its true identifier. For partitioned entities, the topmost 16 bits reflect the partition identifier. Sequence numbers monotonically increase and are gapless. They roll over to 0 when the 48-

64 bit range is exhausted. This property is read-only.
