20
Q

What does UDP stand for?

A

User Datagram Protocol

21
Q

What type of services is UDP good for?

A

UDP can be beneficial when some data loss is okay, such as in video streaming.

22
Q

What the advantages and disadvantages for Tree network typology?

A

Advantages: Easy to expand the network.

Disadvantages: If the top node is impacted, all devices below it are be impacted.

23
Q

What the advantages and disadvantages for hybrid network typology

A

The advantages and disadvantages depend on the types of networks combined.

24
Q

What the advantages and disadvantages for Ring network typology

A

Advantages:

  • Simple to build.
  • Does not require a central node to manage data transmission.
  • Adding devices to the network is easy.

Disadvantages:

  • If any one device goes down, the entire network is affected. In other words, every device is a point of failure.
  • Latency is variable between devices on the network. For example, devices near one another will trade data quickly, but devices far away will experience high communication delay.
25
Q

What does the dashed line represent in a network devices illustration?

A

The separation from the WAN on the left, to the LAN on the right.

26
Q

What is a load balancer?

A

A load balancer is an intelligent network security device that distributes incoming network traffic across multiple servers.

27
Q

Where would you place a load balancer?

A

Load balancers are typically placed after a firewall, between #2 and #3 in the diagram.

28
Q

Which routing protocols use distance as criteria?

A

Distance-vector routing protocols include RIP and EIGRP.

29
Q

Which routing protocols use speed as criteria?

A

Link-state routing protocols include OSPF.

30
Q

Define binary

A

Binary is a numeric system that uses only two digits. Binary is the most basic form that data travels along a network.

31
Q

What are the two binary states?

A

On (1) and off (0)

32
Q

What are IP addresses used for?

A

A numerical identifier associated with each device on a computer network.

33
Q

What are the two primary versions of IP addresses?

A

IPv4 and IPv6

34
Q

How many octets are in a IPV4 address?

A

Four

35
Q

What is the difference between primary and public IP addresses?

A

A public IP address can be accessed through the internet, while a private IP address is assigned to a device in a private space such as an office or home. Typically, private IP addresses are not directly exposed to the internet, so other people cannot navigate to your personal device.

36
Q

What is CIDR?

A

Classless Inter-Domain Routing is a method for assigning out IP addresses.

37
Q

What is the range of IP addresses in:

192.18.65.0/24

A

192.18.65.0 - 192.18.65.255
