     • user data traffic
     • analog and VoIP phone traffic
     • scanners and printers
     • mobile cell phone traffic
     • electrical system
       

   • What is a definition of a two-tier LAN network design?

     • access and core layers collapsed into one tier, and the distribution layer on a separate tier
     • access and distribution layers collapsed into one tier, and the core layer on a separate tier

   • 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?

     
     
     • 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?

     
     
     • 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
     • FF-FF-FF-FF-FF-FF

   • Refer to the exhibit. Fill in the blank.

     How many collision domains are shown in the topology? 2

     
     

   • Fill in the blank.

     A    converged           network is one that uses the same infrastructure to carry voice, data, and video signals.
