Unit-1 CN & DN

Which type of network typically covers a small building like an office?

• WAN

• LAN

• MAN

• PAN

Which topology requires terminators at both ends of the cable?

• Star

• Bus

• Mesh

• Ring

In a star topology, failure of the central hub results in:

• No impact

• Entire network failure

• Only one node failure

• Data transmission halts completely

Which topology provides multiple redundant paths?

• Ring

• Mesh

• Bus

• Star

The formula for the number of connections in a full mesh with n devices is:

• n

• n-1

• n(n-1)/2

• 2n

Which topology is cheapest but prone to cable failure?

• Bus

• Star

• Mesh

• Ring

Which topology is commonly used in LANs today?

• Bus

• Star

• Ring

• Hybrid

A hybrid topology is best described as:

• A variation of bus topology

• Combination of two or more basic topologies

• A star within a bus

• A ring with redundancy

Which topology is most resilient to single-point failures?

• Ring

• Star

• Mesh

• Bus

In a ring topology, if one device fails (without redundancy):

• Entire network fails

• Only that device is affected

• Only adjacent devices are affected

• Performance slows
