Refer to the exhibit. If host A sends an IP packet to host B, what will the destination address be in the frame when it leaves host A?

• 172.168.10.99

• AA:AA:AA:AA:AA:AA

Which two statements are correct about MAC and IP addresses during data transmission if NAT is not involved? (Choose two.)

• Destination MAC addresses will never change in a frame that goes across seven routers

• A packet that has crossed four routers has changed the destination IP address four times

• Every time a frame is encapsulated with a new destination MAC address, a new destination IP address is needed.

• Destination and source MAC addresses have local significance and change every time a frame goes from one LAN to another.

• Destination IP addresses in a packet header remain constant along the entire path to a target host.

Refer to the exhibit. What three facts can be determined from the viewable output of the show ip interface brief command? (Choose three.)

• The default SVI has been configured

• The switch can be remotely managed.

• Two physical interfaces have been configured.

• One device is attached to a physical interface

A user is executing a tracert to a remote device. At what point would a router, which is in the path to the destination device, stop forwarding the packet?

• when the values of both the Echo Request and Echo Reply messages reach zero

• when the value in the TTL field reaches zero

• when the router receives an ICMP Time Exceeded message

• when the host responds with an ICMP Echo Reply message

• when the RTT value reaches zero
