SOHO Network Configuration Flashcards
SOHO router
A router designed for small or home office networks that works is a multifunction device, including a switch, a firewall, and a DHCP server.
NAT overload
A situation where multiple internal hosts simultaneously share a single public IP address.
Bridge mode
The configuration that turns routing off entirely and causes the router to function as a switch.
DHCP reservation
A specific IP address within a DHCP scope permanently reserved for leased use to a specific DHCP client.
MAC address filtering
A technique implemented on many wireless networks to filter devices that are able to connect to the wireless network.
Network Address Translation (NAT)
A process which allows a router to modify packets to allow for multiple devices to share a single public IP address.
Port forwarding
A technique which redirects all incoming traffic on a given port or port range to a specific local host.
Critical asset
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.
Quality of Service (QoS)
A feature that prioritizes internet traffic for applications, online gaming, Ethernet LAN ports, or specified MAC addresses to minimize the impact of busy bandwidth.
Demilitarized Zone (DMZ)
A portion of an enterprise network that sits behind a firewall but outside of or segmented from the internal network.
Network address translation: One-to-one
: 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.
Network address translation: One-to-many
Multiple internal hosts simultaneously share a single public IP address. Sometimes also called NAT overload.
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?
Port forwarding
Quality of service (QoS) implements packet scheduling to control the flow of traffic and help with network transmission speeds. True or False?
True
What changes the destination address of incoming packets?
DNAT
Name four features of a SOHO router
- 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.
Quality of Service (QoS): It ensures that time-sensitive traffic like VoIP, streaming video, or games gets handled without delay. True or False?
True
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?
True
Quality of Service (QoS): It ensures that small file transfers don’t break up an important teleconference. True or False?
False
Quality of Service (QoS): It must be set on end devices which will be tagging traffic as well as on routers. True or False?
True
Layers of defence: Name all 7 layers in order (centre outwards)
Data Application Host Internal network Perimeter network Physical facility Users and organization
Defense in depth is an information assurance concept in which multiple layers of security controls are placed throughout an information technology system. True or False?
True
You have set a Wi-Fi password but you want some extra protection against unauthorized clients connecting to the network. What feature should you enable?
MAC filtering
Name 3 features of SOHO?
A multifunction device that includes a switch, a firewall, and a DHCP server
A web-based interface that can be accessed from any device on the local network
A user interface to interact with user
Which security mode is used by most of the routers along with an external authentication server?
WPA Enterprise
Which layer is not defined in the defense in depth strategy?
Transport
Application
Data
Host
Transport
Which technique selectively enables or disables TCP and UDP ports on computers or network devices?
Port filtering
What enables external clients to access data on private devices without compromising the security of the internal network as a whole?
DMZ
Which of the following is not true about Quality of Service (QoS)?
It ensures that each size of file transfers don’t break up an important teleconference.
Which of the following changes the source address of outgoing packets?
SNAT
Under which mode does a router turn off the routing function entirely and work as a switch?
Bridge mode
Which of the following can encrypt drives formatted as FAT16, FAT32, exFAT, and NTFS?
BitLocker-To-Go
What is true for one-to-one NAT?
It is a way to make systems behind a firewall and configured with private IP addresses appear to have public IP addresses.
What enables a LAN to use one set of IP addresses for internal traffic and a second set of IP addresses for external traffic?
NAT
Which of the following channels overlap with the nearby networks?
2.4 Ghz
