Domain 2 Flashcards
This protocol is used for file transfers, though it is unsecured.
FTP (File Transfer Protocol)
This is traditionally a layer 2 device and allows VLANs (Virtual Local Area Network) to be created.
Switch
These devices take the signal from a provider, usually an ISP, and convert that signal to a usable signal in your home or small office.
Modem
This is a layer 1 device that has no place in today’s modern networks.
Hub
This is a security zone where we place public-facing services but still under our control.
DMZ (A demilitarized zone (DMZ) is a perimeter network that protects an organization’s internal local-area network (LAN) from untrusted traffic.)
This is good if you want to run services inside your network but don’t have a public IP address to the device.
Port Forwarding
This takes private IP addressing and translates to public IP addressing and vice versa, depending on traffic flow.
NAT (Network Address Translation)
This is a way of network administrators deciding which traffic flowing through the network devices gets precedence over the other traffic.
QoS (Quality of Service)
With this technology, we can create personal area networks.
Bluetooth
This technology is widely used for IoT devices in the home/SOHO.
Zigbee
These are computers with lots of storage space and can support multiple protocols.
File Server
What type of address is used a layer 3 of the OSI model and for routing traffic?

IPv4 is how many bits long? (Direct Answer)
32

128
What is the term used for the device that allows you to get outside your local area network?
Gateway
This type of internet is one of, if not, the most popular forms of internet services available.
Cable
If you need to span distances using wireless, this type of setup might help.
WMN (A wireless mesh network (WMN) is a mesh network created through the connection of wireless access point (WAP) nodes installed at each network user’s locale.)
This is a communication standard for simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network, not really used much today for broadband.
ISDN (Integrated Services Digital Network)
This type of tool is used to attach ends to an unshielded twisted pair. (Direct Answer)
Crimper
We can use this as a hardware test for our NIC on our devices. (Direct Answer)
Loopback Plug
We can use these tools to make sure the pins line up on each end like they are supposed to when making a cable.
Cable Tester
This protocol is used for secure remote connectivity for configuration.
( This is a network communication protocol that enables two computers to communicate)
SSH (Secure Shell)
This protocol is for automatic address distribution on a network.
DHCP (Dynamic Host Configuration Protocol)
This is known as a connectionless protocol for sending data.
UDP (User Datagram Protocol)
