1. Connecting Dissimilar networks (ex. lan and wan) 2. Interpreting layer 3 and often layer 4 addressing 3. Determining the best path for data to follow from point A to point B 4. Rerouting the traffic if the first choice path is down but another is available.

four functions all routers do?

RIP, RIPv2, and OSPF

List Three IGPs?

TCP

Which protocol's header would a Layer 4 device read and process?

ARP and ICMP

Which two protocols manage neighbor discovery processes on IPv4 networks?

Network Layer (Layer 3)

Which OSI Layer is responsible for directing data from one lan to another?

Hop Count, Latency, and Routing Cost

3 examples of routing metrics used by routers to determine the best of various available routing paths?

Tshark

A network protocol analyzer. that lets you capture packet data from a live network, or read packets from a previously saved capture file, either printing a decoded form of those packets to the standard output or writing the packets to a file. Just like Wireshark but is for linux?

Administrative Distance or AD

A routing protocol's reliability and priority are rated by what measurements?

Network Layer (Layer 3)

At which OSI Layer does IP operate?

Routing table which maintain information about where the host are located

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?

1500 bytes

What is the internet standard MTU?

Static Route

What kind of route is created when a network administrator configures a router to use a specific path between nodes?

An ARP table can contain two types of entries: dynamic and static. Dynamic ARP table entries are created when a client makes an ARP request that could not be satisfied by data already in the ARP table. Static ARP table entries are those that someone has entered manually using the ARP utility.

what is the difference between dynamic ARP table entries and Static ARP table entries?

three-step handshake

what process is used to establish a TCP connection?

BGP (Border Gateway Protocol)

which routing protocol does an exterior router use to collect data to build its routing tables?

gateway of last resort

When a route is created when a network administrator configures a router to use a specific path between nodes?
