Question

A company is experiencing multiple switch failures. The network analyst discovers the following:

  • Network recovery time is unacceptable and occurs after the shutdown

of some switches.

  • Some loops were detected in the network.
  • No broadcast storm was detected.

Which of the following is the most cost-effective solution?

Options

  • AAdd a new Layer 3 switch.
  • BAdd multiple VLANs.
  • CImplement STP.
  • DImplement tagging.

Explanation

Spanning Tree Protocol (STP) is purpose-built to solve exactly the two problems described: preventing Layer 2 loops and managing network convergence when topology changes occur (such as a switch shutdown). No broadcast storm was detected, which means the loops have not yet escalated, making this the right time to implement STP proactively. Adding a Layer 3 switch (A) addresses routing, not Layer 2 loops. Adding VLANs (B) segments traffic but doesn't resolve loop prevention or recovery time. Implementing tagging (D) relates to VLAN trunk configuration and does not address looping. STP requires no new hardware and is the most cost-effective solution.
