- This version of FTP has no security, no dir navigation options & uses UDP connectionless protocol
- Trivial FTP (TFTP)
- Is SMTP connection oriented or connectionless?
- connection oriented
- http uses what connection protocol? What layer does it function at?
- UDP; 7
- Which 2 protocols are methods for downloading email from a server? Which one transmits passwords in clear text?
- pop & imap; pop
- What does telnet use for transport? What alternative is more secure?
- tcp;ssh
- This protocol is a tool that IP uses in its quest to provide best-effort delivery.
- Internet Control Message Protocol (ICMP)
- What's the most commonly used function of ICMP
- ping utility
- If IP determines that the destination is on the local network, it consults this to determine whether it has a corresponding entry.
- Address Resolution Protocol (ARP) Cache
- This protocol facilitates the communication of time information between systems & uses TCP

- When CompTIA states "identify the well-known ports," it is referring to this?
- ports 0-1023
- On networks where there is no DNS server, it is possible to resolve hostnames to IP address using what file?
- hosts
- This allows networks to access the Internet through a single connection
- Network Address Translation (NAT)
- A Windows Implementation of NAT intended for small networks
- Internet Connection Sharing (ICS)
- This management protocol allows network devices to communicate information about their state to a central system
- Simple Network Management Protocol.

- Traps
- The SNMP Management system computer runs a special software called what?
- Network Management Systems (NMS)
- what are the 3 ways netbios names resolution can be performed?
- WINS, LMHOSTS file, broadcasts
- This automatically assigns IP addressing information
- DHCP/BOOTP
- This resolves hostnames to IP addresses
- DNS
- This translates private network addresses into public network addresses
- NAT/ICS
- Provides network management facilities on TCP/IP-based networks
- SNMP
- Resolves NetBIOS names to IP addresses
- WINS
