Chapter 4 exam quiz
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
Which type of address does a switch use to build the MAC address table?
source MAC address
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
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?
-easier to provide redundant links to ensure higher availability -simpler deployment for additional switch equipment
What are two advantages of modular switches over fixed-configuration switches?
-increased scalability -need for fewer power outlets
What two criteria are used by a Cisco LAN switch to decide how to forward Ethernet frames?
-ingress port -destination MAC address
What are two reasons a network administrator would segment a network with a Layer 2 switch?
-to enhance user bandwidth -to isolate traffic between segments
Which two previously independent technologies should a network administrator attempt to combine after choosing to upgrade to a converged network infrastructure?
-user data traffic -VoIP phone traffic
Match the forwarding characteristic to its type: 1, cut-through 2, store-forward
1, appropriate for high performance computing applications forwarding process can begin after receiving the destination address may forward invalid frames 2, error checking before forwarding only forwards valid frames forwarding process only begins after receiving the entire frame
Match the functions to the corresponding layers: 1, Access layer 2, distribution layer 3, Core layer
1, represent the network edge provides network access to users 2, implements network access policy establishes layer 3 routing boundaries 3, provide high-speed backbone connectivity functions as an aggregator for all the campus blocks
Math the borderless switched network guideline description to the principle. 1, flexibility 2, hierarchical 3,modularity 4,resilence
1, · Allows intelligent traffic load sharing by using all network resources 2,Facilitates understanding the role of each device at every tier, simplifies deployment, operation, and management, and reduces fault domains at every tier 3, · Allows seamless network expansion and integrated service enablement on an on-demand basis 4, · Satisfies user expectations for keeping the network always on
What is the destination address in the header of a broadcast frame?
FF-FF-FF-FF-FF-FF
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.
Which statement describes a result after multiple Cisco LAN switches are interconnected?
The broadcast domain expands to all switches
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
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
What type of network uses one common infrastructure to carry voice, data, and video signals?
converged
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
Which network device can serve as a boundary to divide a Layer 2 broadcast domain?
router
