1. What is one advantage of using the cut-through switching method instead of the store-and-forward switching method?

has a positive impact on bandwidth by dropping most of the invalid frames

makes a fast forwarding decision based on the source MAC address of the frame

has a lower latency appropriate for high-performance computing applications

provides the flexibility to support any mix of Ethernet speeds

2. A network designer must provide a rationale to a customer for a design which will move an enterprise from a flat network topology to a hierarchical network topology. Which two features of the hierarchical design make it the better choice? (Choose two.)

reduced cost for equipment and user training

less required equipment to provide the same performance levels

simpler deployment for additional switch equipment

easier to provide redundant links to ensure higher availability

lower bandwidth requirements

3. What are two advantages of modular switches over fixed-configuration switches? (Choose two.)

availability of multiple ports for bandwidth aggregation

lower forwarding rates

need for fewer power outlets

lower cost per switch

increased scalability

Refer to the exhibit. Consider that the main power has just been restored. PC1 asks the DHCP server for IPv4 addressing. The DHCP server sends it an IPv4 address. While PC2 is still booting up, PC3 issues a broadcast IPv4 DHCP request. To which port will SW1 forward this request?

to Fa0/1, Fa0/2, and Fa0/4 only

to Fa0/1, Fa0/2, Fa0/3, and Fa0/4

to Fa0/1 and Fa0/2 only

to Fa0/1, Fa0/2, and Fa0/3 only

to Fa0/1 only

5. What is one function of a Layer 2 switch?

forwards data based on logical addressing

learns the port assigned to a host by examining the destination MAC address

duplicates the electrical signal of each frame to every port

determines which interface is used to forward a frame based on the destination MAC address

Refer to the exhibit. Fill in the blank.

There are ” 12 ” collision domains in the topology.

7. What is a collapsed core in a network design?

a combination of the functionality of the access, distribution, and core layers

a combination of the functionality of the access and core layers

a combination of the functionality of the distribution and core layers

a combination of the functionality of the access and distribution layers

8. What are two reasons a network administrator would segment a network with a Layer 2 switch? (Choose two.)

to enhance user bandwidth

to eliminate virtual circuits

to create more broadcast domains

to isolate traffic between segments

to isolate ARP request messages from the rest of the network

to create fewer collision domains

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 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 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 drops the frame because it does not know the destination MAC address.

10.

Place the options in the following order:

Cut-through

appropriate for high performance computing applications
forwarding process can begin after receiving the destination address
may forward invalid frames

Store-and-forward

error checking before forwarding
forwarding process only begin after receiving the entire frame
only forward valid frames

11. What is a basic function of the Cisco Borderless Architecture distribution layer?

aggregating Layer 3 routing boundaries

aggregating all the campus blocks

acting as a backbone

providing access to the user

12. ABC, Inc. has about fifty hosts in one LAN. The administrator would like to increase the throughput of that LAN. Which device will increase the number of collision domains and thereby increase the throughput of the LAN?

hub

host

NIC

switch

13. What does the term “port density” represent for an Ethernet switch?

the numbers of hosts that are connected to each switch port

the speed of each port

the memory space that is allocated to each switch port

the number of available ports

14. Which type of transmission does a switch use when the destination MAC address is not contained in the MAC address table?

anycast

unicast

broadcast

multicast

15. What is a basic function of the Cisco Borderless Architecture access layer?

aggregates Layer 3 routing boundaries

provides high availability

aggregates Layer 2 broadcast domains

provides access to the user

16. What information is added to the switch table from incoming frames?

source MAC address and incoming port number

destination MAC address and incoming port number

destination IP address and incoming port number

source IP address and incoming port number

17. Fill in the blank.

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

18. An administrator purchases new Cisco switches that have a feature called StackPower. What is the purpose of this feature?

It enables many switches to be connected with a special fiber-optic power cable to provide higher bandwidth.

It enables the sharing of power among multiple stackable switches.

It enables many switches to be connected to increase port density.

It enables many switches to be physically stacked in an equipment rack.

It enables AC power for a switch to be provided from a powered patch panel.

19. Which switch form factor should be used when large port density, fault tolerance, and low price are important factors?

fixed-configuration switch

modular switch

stackable switch

rackable 1U switch
