Networking Unit 4 Network Protocols and Routing

At which OSI Layer does IP operate?

• Application Layer

• Transport Layer

• Network Layer

• Data Link Layer

What kind of route is created when a network administrator configures a router to use a

specific path between nodes?

• Trace Route

• Static Route

• Dynamic Route

• Default Route

What kind of route automatically calculates the best path between two networks and accumulates this information in its routing table?

• Static Route

• Default Route

• Dynamic Route

• Gateway Route

When a router can’t determine a path to a message’s destination, where does it send the

message?

• Default Gateway

• Administrative Distance

• Routing Table

• Gateway of Last Resort

What characteristics about TCP distinguish it from UDP?

• Connectionless and unreliable delivery.

• Small segment size.

• Source and Destination address is 32 bits each.

• Three way handshake and reliable delivery.

What three-step process uses the Transport layer protocols establish a connection between nodes?

• ICMP Pings

• Time to Live

• Three-way handshake

• Triple packet mode

A record in an ARP table that is created when a client makes an ARP request that cannot be satisfied by data already in the ARP table.

• Static ARP table entries

• Dynamic ARP table entries

• MAC table entries

• DHCP table entries

A record in an ARP table that someone has manually entered using the ARP utility.

• Static ARP table entries

• Dynamic ARP table entries

• MAC table entries

• DHCP table entries

A core protocol in the TCP/IP suite that belongs in the Data Link layer of the OSI model. _____ works in conjunction with IPv4 to discover the MAC address of a node on the local network and to maintain a database that maps local IP addresses to MAC addresses.

• ICMP (Internet Control Message Protocol)

• IP (Internet Protocol)

• ARP (Address Resolution Protocol)

• UDP (User Datagram Protocol)

What type of router directs data between networks within the same autonomous system, also called core router?

• Lan Routers

• Edge Routers

• Exterior Routers

• Interior Routers
