Which configuration is recommended to ensure network redundancy when upgrading network infrastructure?

1. Single connection to the internet

2. Dual connections with load balancing

3. VPN tunnels between buildings

4. Direct wiring to each device

The correct answer is: Dual connections with load balancing

Opting for dual connections with load balancing is a recommended configuration for ensuring network redundancy during infrastructure upgrades. This approach allows for continuous availability and better performance. If one connection experiences issues or goes down, the load balancing mechanism seamlessly redistributes the network traffic across the other available connection. This not only prevents downtime but also optimizes bandwidth utilization, contributing to overall efficiency. In contrast, a single connection to the internet creates a single point of failure, which would jeopardize network availability in case of an outage. VPN tunnels between buildings, while useful for secure communications, do not inherently provide redundancy for internet connections. Direct wiring to each device can improve local network stability but lacks the redundancy aspect, as it's dependent on a single pathway for data transmission. Each of these options fails to match the resilience offered by dual connections combined with load balancing, making them less suitable for a strategy aimed at maximizing uptime and reliability.
