    • A local law firm is redesigning the company network so that all 20 employees can be connected to a LAN and to the Internet. The law firm would prefer a low cost and easy solution for the project. What type of switch should be selected?

      • fixed configuration
      • modular configuration
      • stackable configuration
      • StackPower
      • StackWise
    • What are two advantages of modular switches over fixed-configuration switches? (Choose two.)

      • lower cost per switch
      • increased scalability
      • lower forwarding rates
      • need for fewer power outlets
      • availability of multiple ports for bandwidth aggregation
    • Refer to the exhibit. Consider that the main power has just been restored. PC3 issues a broadcast IPv4 DHCP request. To which port will SW1 forward this request?

      CCNA2 Chapter 1 v5.03 004
      • to Fa0/1 only
      • to Fa0/1 and Fa0/2 only
      • to Fa0/1, Fa0/2, and Fa0/3 only
      • to Fa0/1, Fa0/2, Fa0/3, and Fa0/4
      • to Fa0/1, Fa0/2, and Fa0/4 only
    • What is one function of a Layer 2 switch?

      • forwards data based on logical addressing
      • duplicates the electrical signal of each frame to every port
      • learns the port assigned to a host by examining the destination MAC address
      • determines which interface is used to forward a frame based on the destination MAC address
    • Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty?

      CCNA2 Chapter 1 v5.03 002
      • SW1 floods the frame on all ports on the switch, excluding the interconnected port to switch SW2 and the port through which the frame entered the switch.
      • SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.
      • SW1 forwards the frame directly to SW2. SW2 floods the frame to all ports connected to SW2, excluding the port through which the frame entered the switch.
      • SW1 drops the frame because it does not know the destination MAC address.
    • What two criteria are used by a Cisco LAN switch to decide how to forward Ethernet frames? (Choose two.)

      • path cost
      • egress port
      • ingress port
      • destination IP address
      • destination MAC address
    • Which network device can be used to eliminate collisions on an Ethernet network?

      • firewall
      • hub
      • router
      • switch
    • Which type of address does a switch use to build the MAC address table?

      • destination IP address
      • source IP address
      • destination MAC address
      • source MAC address
    • What are two reasons a network administrator would segment a network with a Layer 2 switch? (Choose two.)

      • to create fewer collision domains
      • to enhance user bandwidth
      • to create more broadcast domains
      • to eliminate virtual circuits
      • to isolate traffic between segments
      • to isolate ARP request messages from the rest of the network
    • Refer to the exhibit. How many broadcast domains are displayed?

      • 1
      • 4
      • 8
      • 16
      • 55
    • Which statement describes the microsegmentation feature of a LAN switch?

      • Frame collisions are forwarded.
      • Each port forms a collision domain.
      • The switch will not forward broadcast frames.
      • All ports inside the switch form one collision domain.
    • What is the destination address in the header of a broadcast frame?

      • 0.0.0.0
      • 255.255.255.255
      • 11-11-11-11-11-11
