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 |
|
What is a collapsed core in a network design |
a combination of the functionality of the distribution and core layers |
|
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 |
|
What is a basic function of the Cisco Borderless Architecture distribution layer? |
aggregating Layer 3 routing boundaries |
|
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 |
|
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 |
|
What are two advantages of modular switches over fixed-configuration switches? (Choose two.) |
increased scalability need for fewer power outlets |
|
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 two criteria are used by a Cisco LAN switch to decide how to forward Ethernet frames? (Choose two.) |
ingress port destination MAC address |
|
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 |
|
What is one function of a Layer 2 switch? |
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 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. |
|
Refer to the exhibit. How many broadcast domains are displayed? |
8 |
|
Which solution would help a college alleviate network congestion due to collisions? |
a high port-density switch |
|
Which network device can serve as a boundary to divide a Layer 2 broadcast domain? |
router |
|
What is the destination address in the header of a broadcast frame? |
FF-FF-FF-FF-FF-FF |
|
What does the term "port density" represent for an Ethernet switch? |
the number of available ports |
|
Which statement describes a result after multiple Cisco LAN switches are interconnected? |
The broadcast domain expands to all switches. |
|
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 |
|
Fill in the blank. A ____________ network is one that uses the same infrastructure to carry voice, data, and video signals. |
converged |
|
allows intelligent traffic load sharing by using all network resources |
flexibility |
|
facilitates understanding the role of each device at every tier, simplifies deployment, operation, management, and reduces fault domains at every tier |
hierarchical |
|
allows seamless network expansion and integrated service enablement on an on-demand basis |
modularity |
|
satisfies user expectations for keeping the network always on |
resiliency |
|
represents the network edge provides network access to the user |
access layer |
|
implements network access policy establishes Layer 3 routing boundaries |
distribution layer |
|
provides high-speed backbone connectivity |
core layer |
|
appropriate for high performance computing applications forward process can begin after receiving the destination address may forward invalid frames |
cut-through |
|
error checking before forwarding forwarding process only begins after receiving the entire frame only forwards valid frames |
store-and-forward |
