Q

What are CIFS / SMB?

A

Common Internet File System / Server Message Blocks. From Microsoft, was made to try and support printer and file shiaring between other operating systems. The default file and printer based protocol on windows since windows 2000.

26
Q

What port is CIFS / SMB on?

A

Port 445

27
Q

What is SLP?

A

Service Location Protocol. Used to help find resources on a network.

28
Q

What port is SLP on?

A

port 427

29
Q

What is AFP?

A

Apple Filing Protocol. Used by Apple for file services and transfers.

30
Q

What port is AFP on?

A

port 548

31
Q

What is DHCP?

A

Dynamic Host Configuration Protocol. Dynamically assigns IP addresses to network clients.

32
Q

What port is DHCP on?

A

port 67 and 68

33
Q

What is LDAP?

A

Lightweight Directory Access Protocol. Directory server protocol. Designed to access information in an information directory. TCP.

34
Q

What port is LDAP

A

port 389

35
Q

What is SNMP

A

Simple Network Management Protocol. Used for collecting and organizing network performance information. TCP.

36
Q

What port is SNMP on?

A

162 and 163

37
Q

What are the differences between TCP and UDP?

A

TCP guarantees packet delivery through a virtual circuit and acknowledgements and UDP does not. TCP is connection based and UDP is connectionless. UDP is faster than TCP.

38
Q

What is UDP?

A

User Datagram Protocol

39
Q

What is ICMP?

A

Internet Control Message Protocol. Responsible for delivering error messages

40
Q

What is ARP?

A

Address Resolution Protocol. Resolves logical IP addresses to MAC addresses

41
Q

What is RARP?

A

Reverse Address Resolution Protocol. Resolves MAC addresses to IP addresses

42
Q

Any device with an IP address assigned to it is referred to as a what?

A

A host. This can include servers, workstations, printers, routers, and other devices.

43
Q

Each of the four grouped numbers in an IP address are known as a what?

A

An octet

44
Q

An IP address is an example of what kind of address structure?

A

A hierarichal address structure

45
Q

What two parts make up and IP address?

A

The network ID and the Host ID

46
Q

How are computers able to different the different parts of an IP address? (Network ID and Host ID)

A

By using a subnet mask

47
Q

Using the following IP and subnet masks as examples, what are you being told?

192.168.10.55 / 255.255.255.0

A

That the first three octets are the network portion of the address and the last octet is the host portion.

192.168.10 = network portion

55 = host portion

48
Q

For a computer to communicate using IPv4 what is it required have?

A

It must have an IP address and correct subnet mask. A third component called the default gateway is required if you want the computer to communicate with others outside the local network.

49
Q

What are the three types of IPv4 address classes?

A

Class A - First eight bits are the network. The remaining 24 bit are for the hosts For large networks.

Class B - First sixteen bits for the network and the remaining 16 bits for the hosts. For medium sized networks.

Class C - First 24 bits are for the network and the remianing 8 bits are for the host. For smaller networks

50
Q

What does DHCP do?

A

Dynamic Host Configuration Protocol provies IP configuration information to clients automatically, in what is called a lease.

51
Q

When would you use DHCP reservation?

A

Some hosts needs a static IP address such as routers, servers, printers etc.. A DHCP sever can be configured to always give these hosts the same IP address but assigning the IP address to a specific MAC address.

52
Q

What is NAT service?

A

Network Address Translation. It translates private, non-routable IP addresses into public IP addresses

53
Q

What is CIDR?

A

Classless Inter-Domain Routing.

54
Q

What is different about the address structure of IPv6 than IPv4?

A

It uses a 128 bit hexidecimal address structure where as IPv4 uses 32 decimal structure.

55
Q

What are the two ways to shorten a IPv6 address?

A

Either by removing the leading zeros in the address or by converting consecutive zeros to double colons.

56
Q

What are unicast, anycast and multicast when referring to IPv6?

A

Different types of IPv6 addresses:

unicast = single node

anycast = referred to multiple nodes

multicast = used by multiple hosts.

57
Q

What would a VLAN be used for?

A

Virtual Local Area Networks are used to help segment physical networks into multiple logical (virtual) networks.

58
Q

What is a VPN?

A

Virtual Private Network. It is a secure network connection that occurs through a pubic network.
