Chapter 5: Networking Devices

Question 1

What is created by connecting three hubs together and then connecting one of those hubs to a router? pg. 158

Answer 1

Once collision domain and one broadcast domain

Question 2

T/F Bridges and switches are used to segment networks, but they will not isolate broadcast or multicast packets. pg. 158

Answer 2

True

Question 3

In order to provide inter-VLAN communication within a switched network, what else would you need? pg. 159

Answer 3

Router

Question 4

Do you know the best network design? pg. 159

Answer 4

LAN switches with routers correctly placed in the network

Question 5

Since you know each interface in a router represents a separate network, what keeps the varied interface networks separated? pg. 160

Answer 5

unique network identification numbers in which each host on the network connected to that router must also use the same network number

Question 6

What’s a few default characteristics of a router? pg. 160

Answer 6

will not forward broadcast or multicast packets

Question 7

The router determines the next hop to foward a packet by reviewing the __ __ on the Network __ __. pg. 160

Answer 7

logical address; layer header

Question 8

Why is Layer 2 switching considered hardware-based bridging? pg. 161

Answer 8

specialized hardware it uses called ASIC / application-specific integrated circuit

Question 9

The time measured from when a frame enters a port to when it exits. pg. 161

Answer 9

latency

Question 10

Where is the information that helps a Layer 2 device determine the location of the specific sending device logged? pg. 161

Answer 10

in the bridge or switch filter table

Question 11

Networks are to routers as devices are to __ and __. pg. 162

Answer 11

switches and bridges

Question 12

What’s the main benefit of a switch over a hub in the internetwork?

Answer 12

each switch port is it’s own collision domain

Question 13

How are hubs and multiple-port repeaters the same? pg 162

Answer 13

receives and regenerates a signal and then forwards out to active ports without reviewing the data

Question 14

What’s good advice to ensure your devices and servers do not overheat or lose power? pg. 163

Answer 14

dedicate a room/suite to place the entire system on a UPS with a backup generator

Question 15

What are the adverse effects of humidity on systems? pg. 163

Answer 15

If it’s too dry, that’ll cause static electricity and too damp, the connections start corroding and short begin to occur
