CCNA2 6.0 Chapter 4
Refer to the exhibit. How many broadcast domains are displayed?
8
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 VoIP phone traffic
implements network access policy establishes Layer 3 routing boundaries
distribution layer
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.)
easier to provide redundant links to ensure higher availability simpler deployment for additional switch equipment
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
allows intelligent traffic load sharing by using all network resources
flexibility
Which type of address does a switch use to build the MAC address table?
source MAC address
error checking before forwarding forwarding process only begins after receiving the entire frame only forwards valid frames
store-and-forward
Which network device can be used to eliminate collisions on an Ethernet network?
switch
What does the term "port density" represent for an Ethernet switch?
the number of available ports
What are two reasons a network administrator would segment a network with a Layer 2 switch? (Choose two.)
to enhance user bandwidth to isolate traffic between segments
What is the destination address in the header of a broadcast frame?
FF-FF-FF-FF-FF-FF
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?
Fa0/1, 2, 3 only
Which statement describes a result after multiple Cisco LAN switches are interconnected?
The broadcast domain expands to all switches.
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 SW1, excluding the port through which the frame entered the switch
A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic?
Segment the LAN into smaller LANs and route between them.
What is a collapsed core in a network design
a combination of the functionality of the distribution and core layers
Which solution would help a college alleviate network congestion due to collisions?
a high port-density switch
represents the network edge provides network access to the user
access layer
What is a basic function of the Cisco Borderless Architecture distribution layer?
aggregating Layer 3 routing boundaries
Fill in the blank. A ____________ network is one that uses the same infrastructure to carry voice, data, and video signals.
converged
provides high-speed backbone connectivity functions as an aggregator for all the campus blocks
core layer
appropriate for high performance computing applications forward process can begin after receiving the destination address may forward invalid frames
cut-through
What is one function of a Layer 2 switch?
determines which interface is used to forward a frame based on the destination MAC address.
What is a definition of a two-tier LAN network design?
distribution and core layers collapsed into one tier, and the access layer on a separate tier
facilitates understanding the role of each device at every tier, simplifies deployment, operation, management, and reduces fault domains at every tier
hierarchical
What are two advantages of modular switches over fixed-configuration switches? (Choose two.)
increased scalability need for fewer power outlets
What two criteria are used by a Cisco LAN switch to decide how to forward Ethernet frames? (Choose two.)
ingress port destination MAC address
allows seamless network expansion and integrated service enablement on an on-demand basis
modularity
satisfies user expectations for keeping the network always on
resiliency
Which network device can serve as a boundary to divide a Layer 2 broadcast domain?
router
