Which of the following must be considered when designing a high-availability network? (Choose two).

High-availability networks aim to minimize downtime and ensure continuous operation. Ease of recovery is crucial because, despite best efforts, failures can occur. A system that can be quickly restored to an operational state reduces the impact of outages. Responsiveness, often measured by latency and throughput, is also vital. A highly available network must not only be up but also perform effectively to meet user and application demands. Ability to patch is important for security and functionality but is a maintenance consideration, not a core design principle for high availability itself. Physical isolation might be used for security but can complicate high availability by creating single points of failure or hindering redundancy. Attack surface is a security concern, not a direct high-availability design consideration. Extensible authentication relates to security and access control, not the network's continuous operational state.
