Exam 4: Data Link and Network Layer Protocols in Tcp/Ip

Match each item with a statement below. a.internal route entry b.areas c.BGP d.Link Control Protocol (LCP) e.Point-to-Point Protocol over Ethernet (PPPoE) f.ARP cache g.hardware address h.route resolution process i.host route -a special connection negotiation protocol that PPP uses to establish point-to-point links between peers for ongoing communications

How do link-state routing protocols differ from distance vector routing protocols?

What type of routing protocol uses information about the distances between networks rather than the amount of time it takes for traffic to make its way from the source network to the destination network?

Provide a brief description of the two types of route table entries.

Two examples of routing protocols that support multiple types of services are OSPF and which of the following?

All IPv4 packets have a predefined lifetime indicated in which field?

In a RIPv2 packet, which field contains a plain text password?

Which of the following is a method that allows an IP host to use a simplified subnetting design?

The method distance vector protocols use to prevent packets from endlessly circulating around a routing loop is called ____________________.

The ____________________ field is a two-byte field that provides bit-level integrity checks for data as sent.

Match each item with a statement below. a.internal route entry b.areas c.BGP d.Link Control Protocol (LCP) e.Point-to-Point Protocol over Ethernet (PPPoE) f.ARP cache g.hardware address h.route resolution process i.host route -that process that a host undergoes to determine whether a desired destination is local or remote and, if remote, which next-hop router to use

Which of the following prevents a router from advertising a network on the same interface from which it learned that network?

Which of the following occurs on a network when ICMP is turned off and a router discards packets without sending any notification about its actions?

Discuss three ways in which a router entry can be placed in a routing table.

What is required to get the packet from one IP host to another IP host on a single network?

A network is usually said to be converged when all the routers know a loop-free path to get to all other networks.

If a packet with TTL=1 arrives at a router, the router must discard the packet because it cannot decrement the TTL to 0 and forward the packet.

Match each item with a statement below. a.internal route entry b.areas c.BGP d.Link Control Protocol (LCP) e.Point-to-Point Protocol over Ethernet (PPPoE) f.ARP cache g.hardware address h.route resolution process i.host route -an interdomain routing protocol that replaces Exterior Gateway Protocol (EGP)

____________________ system routing enables BGP peer routers to exchange routing information across an AS that does not support BGP.

Briefly describe the following fields in the PPP header and trailer: Flag, protocol identifier, and Frame Check Sequence.
