CSCI 304 Networking and Security Chapter Four
ICMP and ARP
Which two protocols manage neighbor discovery processes on IPv4 networks?
hop count, bandwidth, throughput
Give three examples of routing metrics used by routers to determine the best of various available routing paths
TCP is guaranteed, uses checksums, and is connection oriented
What three characteristics distinguish TCP from UDP?
gateway of last resort
When a router can't determine a path to a message's destination, where does it send the message?
Network Layer
Which OSI layer is responsible for directing data from one LAN to another?
AD
A routing protocol's reliability and priority are rated by what measurement?
Network Layer
At which OSI layer does IP operate?
routing table
What database does a router consult before determining the most efficient path for delivering a message?
Checksum
What field in a TCP segment is used to determine if an arriving data unit exactly matches the data unit sent by the source?
dynamic is automatic, static is manually entered
What is the difference between dynamic ARP table entries and static ARP table entries?
Static Route
What kind of route is created when a network administrator configures a router to use a specific path between nodes?
Three-way handshake
What process is used to establish a TCP connection?
