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?
