An environment has a dual-stack infrastructure in an active-active configuration in two separate data centers. Which of the following best describes replication between the two sites?

Hot-site and warm-site terminology describes an active-passive (not active-active) disaster recovery model, where one site is primary and the other is a standby.

A 15-minute replication interval is near-real-time or periodic replication, which is characteristic of a warm-standby or active-passive setup, not an active-active configuration.

Once-per-day data movement is a scheduled batch replication strategy inconsistent with active-active, where both sites must reflect the same live state at all times.

In an active-active configuration, both data centers handle live traffic concurrently, which means data must be synchronized in real time to ensure both sites always have identical, current state. Any lag or scheduled batch would cause data inconsistency across sites serving live users. Real-time replication is the defining technical characteristic that makes active-active viable.

Twice-daily bidirectional replication is still a periodic batch schedule and would result in significant data divergence between sites serving live workloads.
