Networking Essentials
Q1. You have a DHCP server and and WINS server.Your are using TCP/IP,You can communicate with the network using the IP address, but not when using the servers name.
What do you examine first?
DHCP server.
WINS server
Gateway
Router
Q2. Required: Reduce the utilization by 50%
Options:
Continue growth
Maintain new network utilization.
Minimize costs.
Proposal: Reduce the packet size from 1514 to 576 bytes. Increase the TCP/IP window size from 4096 to 16384. Replace the Cat 3 cables with Cat 5.
Required plus all options.
