Suggested Answer:A🗳️
The WebLogic Server Administration Console enables you to configure, modify, target, and delete destination key resources in a system module. Incorrect Answers: B: As messages arrive on a specific destination, by default they are sorted in FIFO (first-in, first-out) order, which sorts ascending based on each message's unique JMSMessageID. However, you can use a destination key to configure a different sorting scheme for a destination, such as LIFO (last-in, first-out). C: Attribute Sort Key: The message sort key or the name of a message header field on which to sort. Message header field keys start with the letters JMS and ignore the key type setting. Valid values only (user-defined sort key not possible): ✑ JMSMessageID ✑ JMSTimestamp ✑ JMSCorrelationID ✑ JMSPriority ✑ JMSExpiration ✑ JMSType ✑ JMSRedelivered ✑ JMSDeliveryTime Reference: https://docs.oracle.com/cd/E13222_01/wls/docs90/jms_admin/basic_config.html#1105573
