CCNA Exploration 3 LAN Switching and Wireless – Chapter 5 Exam

01. Refer to the exhibit. All switches in the network have empty MAC tables. STP has been disabled on the switches in the network. How will a broadcast frame that is sent by host PC1 be handled on the network?

  • Switch SW1 will block the broadcast and drop the frame.
  • Switch SW1 will forward the broadcast out all switch ports, except the originating port. This will generate an endless loop in the network.
  • Switch SW1 will forward the broadcast out all switch ports, except the originating port. All hosts in the network will reply with a unicast frame sent to host PC1.
  • Switch SW1 will forward the traffic out all switch ports except the originating port as a unicast frame. All hosts in the network will reply with a unicast frame sent to switch SW1. Read the rest of this entry »

CCNA Exploration2: Routing Protocols –Chapter 3 Exam

01. Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)

  • Administrative distance refers to the trustworthiness of a particular route.
  • A router first installs routes with higher administrative distances.
  • The value of the administarive distance can not be altered by the network administrator.
  • Routes with the smallest metric to a destination indicate the best path.
  • The metric is always determined based on hop count.
  • The metric varies depending which Layer 3 protocol is being routed, such as IP or IPX.
