Net Device Operation PE Flashcards
What network device breaks up collision domains, but NOT broadcast domains?
switch
A Wi-Fi dongle is an example of a network adapter. T or F
True
A hub will automatically use ______ addressing to forward traffic to all hosts, unlike a switch, which tends to use unicast addressing.
broadcasting
What networking device receives incoming signals, regenerates them, then retransmits them past their attenuation length, while reducing the interference affecting the signal?
repeater
What type of NAT provides some security, regarding the inability to determine what private node is the source of public traffic, because it uses a pool of public IPs for their private network?
dynamic
What form of NAT provides security, by also hiding internal infrastructure, but only has a singular public IP that all private traffic uses?
PAT (Port Address Translation)
_____ perform address learning on all traffic processed, which helps them make future decisions on forwarding and routing.
router
Configuring the ports on a hub to not broadcast by default is among the first things to do before you install one. T or F
False
What switch configuration type allows you to modify the way it functions, such as allowing only certain ports to be open, VLANs, and blocking certain MAC addresses from using that switch?
managed
True or False: Dynamic Network Address Translation (NAT) does a better job at hiding your internal (private) infrastructure than Static NAT?
true
What type of networking device is unable to filter data and operates in Half-Duplex?
hub
Routers make forwarding decisions based on what IP address?
destination IP
Which network device allows your computer to communicate across the Physical and Data Link Layers by using standards like Ethernet and Wi-Fi?
NIC
A ___ enables connections between networks and is often seen as an interface on a router.
default gateway
(True or False): Routers share their routing tables with other routers they are connected to.
true
