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

• acting as a backbone
• aggregating all the campus blocks
• aggregating Layer 3 routing boundaries
• providing access to end user devices

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.)

• lower bandwidth requirements
• reduced cost for equipment and user training
• easier to provide redundant links to ensure higher availability
• less required equipment to provide the same performance levels
• simpler deployment for additional switch equipment

What is a collapsed core in a network design?

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

Which two previously independent technologies should a network administrator attempt to combine after choosing to upgrade to a converged network infrastructure? (Choose two.)

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

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
• FF-FF-FF-FF-FF-FF

Refer to the exhibit. Fill in the blank.

How many collision domains are shown in the topology? 2
