- 4004:5cg8:3ed3:0000:0000:0000:5cg8:3ed3

- Improves routing, security, efficiency and more

Which Internet protocol sends management messages between systems?

ICMP - Internet Control Message Protocol

Which Internet protocol allows you to send "Echo Requests or receive Echo Replies"?

(Ping)

ICMP - Internet Control Message Protocol

What Internet protocol manages membership of multi-cast groups which in turn improves efficiency and bandwidth usage?

IGMP - Internet Group Managment Protocol

Which Internet protocol allows multiple users to view the same media stream from a single media source?

IGMP - Internet Group Managment Protocol

Name this Transport Layer protocol:

-connection-oriented

-reliable delivery

- can manage out-of-order messages or retransmissions

TCP - Transmission Control Protocol

-Checks for out-of-order or missing data

Name this Transport Layer protocol:

-connectionless

-unreliable (no checks and balances)

- no reordering of data or retransmissions

UDP - User Datagram Protocol

- Doesn't care about out-of-order data or missing data

What is the primary responsibility of the ARP protocol?

-Address Resolution Protocol

-Map IP address to MAC addresses

At what layer of the TCP/IP suite does the UDP (User Datagram Protocol) reside?

Transport Layer

What is the primary responsibility of IGMP?

-Internet Group Management Protocol

-Manages membership of multicast groups

BOOTP, NDS, SNMP, NTP, Telnet, SSH, FTP, TFTP, SMTP, POP3, IMAP, HTTP, HTTPS, TLS/SSl, SIP, and RTP are all protocols from which Layer?

Application Layer

What protocol automates the IP address configuration process? (replaced by DHCP)

BOOTP - Bootstrap Protocol

Which protocol converts domain names to IP addresses?

DNS - Domain Name Services

This Application Layer protocol automatically synchronizes clocks?

NTP - Network Time Protocol

How many versions of SNMP (Simple Network Managment Protocol) are there?

SNMPv1

SNMPv2

SNMPv3

Which Application Layer protocol allows you to gather statistics from network devices?

SNMP - Simple Network Management Protocol

Out of the three SNMP protocols, which is the only one that offers encryption?

SNMPv3

Telnet (Telecommunication Network) protocol allows you to login to __________ devices?

remote

-Using unencrypted communication

What is the major difference between Telnet and SSH?

Encryption

What is SSH and what is it used for?

SSH - Secure Shell

- Login to devices remotely

-Encrypted communications link

This Application Layer protocol authenticates with a username and password; allowing users to transfer files between systems?

FTP - File Transfer Protocol

The major difference between FTP and _____ is that there is no authentication required on the latter.

TFTP - Trivial File Transfer Protocol

Which protocol is used most often for sending mail and transferring messages between mail servers?

SMTP - Simple Mail Transfer Protocol

______ allows you to receive and store mail locally for later viewing. (Designed for intermittent connectivity)

POP3 - Post Office Protocol version 3

Which mail client protocol offers flexibility in connectivity and keeps "state" of messages (read, replied, deleted...)?

IMAP4 - Internet Message Access Protocol v4

Name the two mail client protocols that allow you to receive mail?

POP3 - Post Office Protocol version 3

IMAP4 - Internet Message Access Protocol v4

______ defines how messages are formatted over the World Wide Web and transmitted, and what actions web servers and browsers should take in response to various commands.

HTTP - Hypertext Transfer Protocol

The major difference between HTTP and HTTPS is?

HTTPS (Hypertext Transfer Protocol Secure) uses a layer of encryption through TLS/SSL.
