The network administrator is testing connectivity from the branch router to the newly
installed application server. What is the most likely reason for the first ping having a
success rate of only 60 percent?
A The network is likely to be congested, with the result that packets are being intermittently dropped.
B The branch router had to resolve the application server MAC address.
C There is a short delay while NAT translates the server IP address.
D A routing table lookup delayed forwarding on the first two ping packets.
E The branch router LAN interface should be upgraded to FastEthernet.
