Explanation
High availability (HA) refers to designing systems with redundancy so that services remain accessible even if a component fails - for example, redundant WAN links, redundant routers, or failover configurations. Since the question emphasizes ensuring both sites remain accessible (i.e., always up and reachable), high availability is the correct solution. Traffic shaping controls how bandwidth is used. QoS prioritizes traffic types. Caching engines reduce repeated data retrieval. None of those address the continuous accessibility and uptime requirement that high availability is designed to solve.
