When LAN connectivity is designed which option increases high availability and minimizes network administration?

Question

Options

• Aintegrated switch in WAN router
• Bstacked switch design
• Cmultiple switch design
• Dsingle external switch design

• A
  13% (3)
• B
  74% (17)
• C
  9% (2)
• D
  4% (1)

Explanation

Stacked switch design (B) provides high availability because multiple physical switches operate as a single logical unit - if one switch fails, the others continue forwarding traffic without manual reconfiguration, and the entire stack is managed through a single interface, dramatically reducing administration overhead.

Why the others fall short:

• A (integrated switch in WAN router) combines functions but creates a single point of failure and limits scalability - losing the router kills both routing and switching.
• C (multiple switch design) improves redundancy but requires managing each switch independently, increasing administration burden (the opposite of the goal).
• D (single external switch) is the worst option - one failure takes down the entire LAN with no redundancy at all.

Memory tip: Think of a stack as a "team" of switches that share one brain - one IP, one config, one management point, but many bodies. If one body falls, the team keeps playing. "Stack = Simple + Survivable."
