Which two statements describe differences between the active and standby systems. (Choose two.)
The correct answer is C. Virtual server addresses are hosted only by the active system. E. Floating selfIP addresses are hosted only by the active system.. In an active-standby configuration, virtual server addresses and floating self-IP addresses are exclusively hosted by the active system to direct traffic and management to the operational unit.

Why each option
In an active-standby configuration, virtual server addresses and floating self-IP addresses are exclusively hosted by the active system to direct traffic and management to the operational unit.
Standby systems also perform monitors to assess resource availability and prepare for failover.
Failover triggers primarily cause the standby system to transition to an active state.
In an active/standby setup, virtual server IP addresses are floating addresses that are owned and responded to only by the currently active device to ensure traffic is directed to the operational unit.
Configuration changes can be initiated on either the active or standby system, though best practice is to make changes on the active system and synchronize them.
Floating self-IP addresses are used for traffic management and are owned by the active system in a high-availability pair, ensuring that network communication for managed objects always routes through the active device.
