TCP & UDP Protocols Flashcards
Which layer of the OSI model does the IP protocol run at?
Layer 2
Layer 3
Layer 4
Layer 3
The IP protocol is responsible for logical addressing and routing, which is a function of layer 3 of the OSI model
Which of the following protocols are layer-4 protocols? (Choose all that apply.)
TCP
IP
ARP
UDP
TCP
UDP
TCP and UDP are transport protocols. TCP is responsible for connection-oriented communication and error-free delivery, whereas UDP is responsible for connectionless communication
Which protocol is responsible for converting the IP address to a MAC address?
IP
TCP
ARP
ARP
he Address Resolution Protocol (ARP) is responsible for converting an IP address to a MAC address so that communication can occur
Which protocol is responsible for sending e-mail across the Internet?
POP3
IMAP4
SMTP
SMTP
The Simple Mail Transport Protocol (SMTP) is responsible for sending mail across the Internet
Which protocol is responsible for connection-oriented communication?
TCP
IP
UDP
TCP
TCP is responsible for connection-oriented communication in the TCP/IP protocol suite
Which protocol is responsible for error reporting and status information?
ICMP
TCP
UDP
ICMP
ICMP is responsible for reporting errors and sending back status information when communicating over TCP/IP
Which protocol is responsible for logical addressing and delivery of packets?
ICMP
TCP
IP
IP
IP is responsible for packet delivery and logical addressing
Jeff is one of the network administrators in your office and he says that he noticed his Windows 8 desktop has a link-local address assigned. Which of the following addresses is his Windows 8 system using?
::1
fe80: :b596:cafa:5ea1:cbf0
2001: :b596:cafa:5ea1:cbf0
fe80::b596:cafa:5ea1:cbf0
A link-local address is automatically assigned to a Windows 8 system and is an address that starts with fe80
How many bits in an IPv6 address?
128 bits
32 bits
48 bits
128 bits
An IPv6 address is made up of 128 bits that are organized into 16-bit blocks separated by a colon (:). Each 16-bit block is made up of a 4-bit hexadecimal character. An example IPv6 address is fe80:0000:0000:0000:b596:cafa:5ea1:cbf0
Which of the following represents an IPv6 global address?
::1
fe80: :b596:cafa:5ea1:cbf0
2001: :b596:cafa:5ea1:cbf0
2001::b596:cafa:5ea1:cbf0
A global address in IPv6 is equivalent to an IPv4 public address and has 2001 as a prefix
Which of the following tunneling protocols would you use to tunnel IPv6 packets in an IPv4 packet when sitting behind a NAT device?
ISATAP
4to6
Teredo
Teredo
Teredo is a tunneling protocol that works behind a NAT device when tunneling IPv6 packets inside IPv4 packets
Which of the following identify benefits of IPv6 over IPv4? (Choose three.)
Auto-configuration
Decreased address space
No broadcast messages
Increased address space
More broadcast messages
Auto-configuration
No broadcast messages
Increased address space
There are a number of benefits to IPv6, such as auto-configuration, no broadcast messages, and increased address space
Which network service is responsible for allowing Microsoft clients access to the file system on a UNIX server?
NFS
SMB
Samba
Samba
Samba is responsible for allowing Microsoft clients to access resources on the UNIX system because Samba implements the SMB protocol
Which network service is responsible for assigning IP addresses to clients on the network?
NAT
WINS
DHCP
DHCP
DHCP is responsible for assigning IP addresses to clients on the network
Which network service is responsible for allowing Microsoft clients to access the file system on Microsoft servers?
SMB
NFS
NAT
SMB
SMB is the protocol in Microsoft environments that allows Microsoft clients to connect to the file system of other Microsoft systems
