Refer to the exhibit.

Based on the provided exhibits, the BIG-IP device is currently in a Standby state ("ONLINE (STANDBY)") and has a sync status of "Changes Pending" (Yellow icon).

Understanding Device State and Traffic: In an Active/Standby High Availability (HA) pair, traffic is processed by the Active device. The exhibit confirms the administrator is logged into the Standby device, which explains why there is "NO traffic" currently observed on this specific unit.

Configuration Synchronization (ConfigSync): When an administrator modifies a local object, such as an iRule, on one member of a device group, the changes must be synchronized to the other members to ensure consistency. The "Changes Pending" status indicates that the local configuration on this device is newer than the configuration on other group members.

Push vs. Pull: * Push: Sends the configuration from the current device to the other members of the device group.

Pull: Overwrites the current device's configuration with the configuration from another member of the group.

Resolving the Scenario: Since the administrator modified the iRule on "this device," they must Push the configuration to the group so the Active device receives the updated iRule. To verify the iRule works, the administrator can then monitor the traffic on the Active device or initiate a manual failover to make "this device" Active, allowing it to process traffic with the new iRule.

Option D is the correct administrative workflow: synchronize the changes to the group (Push) and then monitor the traffic flow to validate the new logic.
