Questions and Answers

What action does a switch take when it is in an STP/RSTP blocking state in a particular VLAN?

  • Forwards all user traffic on that VLAN
  • Receives user traffic but does not send user traffic on that interface in that VLAN
  • Neither sends nor receives user traffic on that interface in that VLAN
  • Blocks all user traffic and does not send or receive user traffic on that interface in that VLAN (correct)
  • What is the primary purpose of STP/RSTP in an Ethernet LAN?

  • To prevent broadcast storms (correct)
  • To manage network topology
  • To prioritize critical traffic
  • To prevent network congestion
  • What is the effect of a broadcast storm on an Ethernet LAN?

  • It increases network security by encrypting broadcast frames
  • It has no impact on network performance
  • It slows down network performance by crowding out good frames (correct)
  • It improves network performance by reducing broadcast traffic
