$(10$ points$)$ IP and MAC addressing. True or False. Circle True or False. One point for each correct answer, zero points for each incorrect answer.

Many of the questions refer to the following network consisting of three $10Mbps$ Ethernet segments, one switch, and one router. Assume all ARP tables are up$-$to$-$date unless otherwise stated.

a$)$ Consider a network consisting of Ethernets, hubs, switches, and routers. Suppose one of the hubs is replaced with a switch. Then the network administrator must redefine some IP addresses.

True False

b$)$ The routing table in an IP module contains Ethernet addresses.

True False

c$)$ Referring to the network in Figure $1,$ suppose workstation $$ wants to send an IP datagram to workstation $F.$ Then the Ethernet frame sent by $$ will contain in its destination address field the Ethernet address for the left router interface.

True False

d$)$ Referring to question $($c$),$ the Ethernet frame sent by $$ will contain $-$ in its information field $-$ the IP address of the left router interface.

True False

e$)$ Referring to question $($c$),$ once the IP datagram is received and determined correct by the router's IP layer, the data field of the datagram is passed to the ronters transport layer.

True False

f$)$ Referring to Figure $1,$ suppose $$ encapsulates an $$ RP request packet in an Ethernet broadcast frame, and sends the frame. The frame is received by node $F.$

True False

g$)$ Referring to Figure $1,$ suppose D encapsulates an ARP request packet in an Ethernet broadcast frame, and sends the frame. The frame is received by node $B.$

True False

h$)$ Suppose that an Ethernet frame contains an ARP response packet. Then the Ethernet frame has all ones $($FF$-$FF$-$FF$-$FF$-$FF$-$FF$)$ in its destination address field.

True False

i$)$ Consider a router in an autonomous system using OSPF. Periodically this router will send parts of its IP table to all routers in the autonomons system.

True False

j$)$ Suppose a host at ASU wants to send a file to a host wine.paris $.$ fr in France. The source host obtains the destination's IP address from its Address Resolution Protocol $($ARP$)$ table.

True False
