SOHO Network Configuration

Question 1

SOHO router

Answer 1

A router designed for small or home office networks that works is a multifunction device, including a switch, a firewall, and a DHCP server.

Question 2

NAT overload

Answer 2

A situation where multiple internal hosts simultaneously share a single public IP address.

Question 3

Bridge mode

Answer 3

The configuration that turns routing off entirely and causes the router to function as a switch.

Question 4

DHCP reservation

Answer 4

A specific IP address within a DHCP scope permanently reserved for leased use to a specific DHCP client.

Question 5

MAC address filtering

Answer 5

A technique implemented on many wireless networks to filter devices that are able to connect to the wireless network.

Question 6

Network Address Translation (NAT)

Answer 6

A process which allows a router to modify packets to allow for multiple devices to share a single public IP address.

Question 7

Port forwarding

Answer 7

A technique which redirects all incoming traffic on a given port or port range to a specific local host.

Question 8

Critical asset

Answer 8

A specific entity of such importance that its replacement or destruction would have an debilitating effect on the ability of an organization to continue to function effectively.

Question 9

Quality of Service (QoS)

Answer 9

A feature that prioritizes internet traffic for applications, online gaming, Ethernet LAN ports, or specified MAC addresses to minimize the impact of busy bandwidth.

Question 10

Demilitarized Zone (DMZ)

Answer 10

A portion of an enterprise network that sits behind a firewall but outside of or segmented from the internal network.

Question 11

Network address translation: One-to-one

Answer 11

: Every internal host that connects to the outside network has its own public IP address, which can either be statically or dynamically assigned from an available pool.

Question 12

Network address translation: One-to-many

Answer 12

Multiple internal hosts simultaneously share a single public IP address. Sometimes also called NAT overload.

Question 13

Name a networking technique through which a gateway transmits all incoming traffic of a specific port to the same port on any internal network node?

Answer 13

Port forwarding

Question 14

Quality of service (QoS) implements packet scheduling to control the flow of traffic and help with network transmission speeds. True or False?

Answer 14

True

Question 15

What changes the destination address of incoming packets?

Answer 15

DNAT

Question 16

Name four features of a SOHO router

Answer 16

• It is a multifunction device including a switch, a firewall, and a DHCP server.
• It includes a wireless access point, VPN, concentrator, broadband modem, or other network appliances integrated into itself.
• It needs a user interface to interact with user.
• It has a web-based interface that can be accessed from any device on the local network.

Answer 17

True

Question 18

Quality of Service (QoS): It can be configured on different layers of the network, and on small and busy networks, it can be a difficult and time-consuming process. True or False?

Answer 18

True

Question 19

Quality of Service (QoS): It ensures that small file transfers don’t break up an important teleconference. True or False?

Answer 19

False

Question 20

Quality of Service (QoS): It must be set on end devices which will be tagging traffic as well as on routers. True or False?

Answer 20

True

Question 21

Layers of defence: Name all 7 layers in order (centre outwards)

Answer 21

Name 3 features of SOHO?

Answer 24

A multifunction device that includes a switch, a firewall, and a DHCP server

Answer 28

DMZ

Question 29

Which of the following is not true about Quality of Service (QoS)?
