Diagnostic tool used to collect data on a LAN?
A network sniffer. It can be hardware based (dedicated device with it's own software) or software based (application running on a PC). An Internet gateway can collect information to bust the user by tracing back the computer name, IP address and who is logged in. A sniffer is used mostly to collect information to help diagnose errors suspectred coming from the lan/wan.
Can multimode and singlemode fiber optic cable be used together?
Not really. These are two different types of fiber optic cable and are used for different reasons. In other words, you can't mix SMF and MMF fiber in the same cable, but they could be used in separate cables in the same network (although it isn't likely)
MMF fiber is used for short haul interconnects, and SMF fiber is typically used for longer distances,
How many /64 subnets are available in a /48 prefix?
There are 65,536 subnets available in an IPv6 /48 block.
Similarity between IP and UDP?
IP and UDP operate at different layers of the OSI model. The IP protocol specifies network layer addressing for routine, and UDP is a transport model.
The one thing that is the same between them is that they are both connectionless methods, meaning that no answer is required from the receiver by the sender for either protocol. We assume the information arrives at the receiver without checking the result.
Define public address and private address?
A public address is one that is seen on the Internet and can be routed. A private IP address is only visible within its organization network and any packets containing a destination address using a private address will not be routed outside the organization.

What is the function of the DNS server?
DNS servers translate requests for domain names into IP addresses. When you type www.answers.com into the address bar of your browser, your request will be handled by a DNS server, which translates your request for www.answers.com into a request for (the website located at) the ip address 67.196.156.65.
The domain name system was invented, because humans are better at remembering names like "answers.com" than remembering IP addresses like "67.196... etc".
A noiseless 4 kHz channel is sampled every 1 msec What is the maximum data rate?
by Nyquist theorem
max data rate = 2H log2 V bits /sec
so H= 4KHz..
and v=2 ( say binary is transmitting )
therefore
max data rate = 2 * 4 *103 *log22 bps
max data rate = 8000 bps
Bcoz it is sampling per 1ms
so
Which two automatic addressing assignments are supported by DHCP?
subnet mask
default gateway address
What happen if the connection in Mesh topology are failed?
First your grammar is incorrect, it should read: "What would happen if the connection in Mesh topology fail?", Second you should reevaluate your categories. Third I believe it would threaten other computers in the network.

1. There is a biggest security risk.
2. Person sharing the router could visit your shared folders and view or copy them
easily.
3. Person sharing the router could hack your system easily.
