Infosys Certified Full Stack - System Admin - Network - Beginner

Bits are packaged into frames at which layer of the OSI model?

A network administrator connected a router with PC using cross over cable for setting up the initial configuration like name, date, time and password. But the admin is not able to open router's console through putty. Identify the necessary solution to open the router's console using putty.

1. Replace the cross over cable to Roll over cable

2. Replace the cross over cable to Straight through cable

3. IP address for Router's console port and PC's ethernet port should be assigned from same subnet

Identify the valid IP Addresses?

Identify the protocols belongs to the layer of the TCP/IP model, which routes each of the data packets independently from the source to the destination, using the optimal route. (Choose two options)

The requirement is to check the connectivity with the Router having the IP address 19.1.1.9. When try pinging this IP address "Request Timed Out" error is coming. What will be the probable reason?

The source device doesn't find route to send echo request to the destination device.

The source device can't reach the port of the destination device.

The destination device can't reach the port of the source device.

The destination device doesn't find route to send echo reply to the source device.

Which command will help to find the physical address(MAC) for the particular Logical address(IP)?

Identify the protocols which perform data transportation during the communication along with reliable and non-reliable data transmission.

A network administrator wants to upgrade the IOS of the switch. Hence the admin connects the switch with PC. Identify the cable which is used by the admin for the given requirement.
