2.3 Given a scenario, install and configure a basic wired/wireless SOHO network.

Question 1

Wireless Ethernet is also known as:

Answer 1

IEEE 802.11

WiFi

Question 2

Wireless Ethernet is:

Answer 2

the collective name for a group of wireless technologies compatible with wired Ethernet

Question 3

Wireless technologies compatible with wired Ethernet is referred to:

Answer 3

wireless LAN (WLAN) standards

Question 4

A SOHO wired or wireless router can provide:

Answer 4

a secure way for users to access the Internet and local network resources

Question 5

A SOHO wired or wireless router can become a magnet for:

Answer 5

attack

Question 6

To connect to a router open a browser and enter:

Answer 6

the IP address of the router in the address bar and press Enter

Question 7

The wireless spectrum is divided into:

Answer 7

11 channels

Question 8

Part of installing a router on a 2.4GHz wireless network is:

Answer 8

selecting an appropriate channel for the signal

For best results, avoid overlapping channels

Question 9

What channels do not overlap with other channels?

Answer 9

1

6

11

Question 10

Some routers feature an Auto setting that enables:

Answer 10

the router to use the least-active channel

Question 11

To change the channel used by a wireless network follow these steps:

Answer 11

1. Log into the router
2. Navigate the wireless configuration dialog
3. Select a different channel (typically 1, 6, or 11 when using 2.4GHz networking because they have less interference than other channels)
4. Save your changes and exit the wireless configuration dialog

Question 12

Network address translation (NAT) is the process of:

Answer 12

modifying IP addresses as information crosses a router

Question 13

Network address translation (NAT) hides:

Answer 13

an entire IP address space on the LAN

Question 14

Whenever an IP address on the LAN wants to communicate with the Internet, the IP address is:

Answer 14

converted to the public IP address of the router

Question 15

SOHO routers perform Network address translation (NAT) automatically when:

Answer 15

connected to an IPv4 network

Question 16

Port forwarding involves:

Answer 16

forwarding external visitors through a router to a specific computer

Question 17

Instead of opening the entire LAN, port forwarding directs:

Answer 17

particular traffic where you want it to go

Question 18

Port forwarding is also called:

Answer 18

destination network address translation (DNAT)

Question 19

Port triggering involves:

Answer 19

a particular service opening an outgoing port or range of ports on demand

Question 20

Port triggering can be used without:

Answer 20

being tied to a specific IP address

Question 21

A demilitarized zone (DMZ) allows:

Answer 21

outside traffic through a particular IP address on a LAN

Question 22

In a SOHO router, any device assigned to the DMZ receives:

Answer 22

traffic that is not specified for a particular device

Question 23

Using a DMZ host makes sense for:

Answer 23

gaming and other types of traffic where you cannot specify in advance the ports needed

Question 24

The DMZ host must have its own:

Answer 24

firewall because DMZ hosts are not protects by the router firewall

Question 25

By default, SOHO routers have the:

Answer 25

DHCP service turned on so they can provide IP addresses to any wired or wireless devices that connect

Question 26

Most routers enable you to:

Answer 26

specify the range and number of IP addresses available via DHCP

Question 27

When do devices switch to Automatic Private IP Addressing (APIPA)?

Answer 27

When a router does not have sufficient IP addresses for the devices that need to connect to it, using the non-routable IP address range 169.254.x.x

Question 28

A SOHO router comes with a:

Answer 28

default IP address known as a private address

Question 29

Follow the steps to configure NIC in Windows:

Answer 29

1. Click the Windows icon and select the Windows Settings gear
2. In the Windows Settings window select the Network & Internet link
3. When you see the different connection options, select the one you want and click Change adapter options on the right side of the window
4. Choose the adapter you want to configure and click on the Properties button. A list of items available to the NIC are listed
5. Double-click on Internet Protocol Version 4 (TCP/IPv4). You now see the window where the IP address is configured dynamically or statically
6. Assign the address or leave the default DHCP options and click OK to accept any changes

Question 30

To access the end-user device configuration windows, you may to:

Answer 30

visit the manufacturer’s support site

Question 31

A few examples of IoT are:

Answer 31

Thermostats

Light switches

Security cameras

Door locks

Voice-enabled smart speakers/digital assistants

Question 32

Quality of service (QoS) is an important feature to enable:

Answer 32

on any network that provides streaming media, gaming, or VoIP services

Question 33

Quality of service (QoS) prioritizes what?

Answer 33

real-time and streaming traffic

Question 34

Quality of service (QoS) can be configured on:

Answer 34

an ISP or by a router

Question 35

Universal plug and play (UPnP) is a:

Answer 35

router feature that enables devices on a network to add themselves to a network without the need to reconfigure the router
