A network administrator is designing a new office network and wants to use a topology that provides redundancy so that if one cable fails, communication can still occur via alternate paths. Which TWO topologies offer this redundancy? (Choose TWO.)
Trap 1: Ring topology
Ring topology does not provide redundancy; a single cable break disrupts the entire network unless a dual ring is used, which is not specified.
Trap 2: Star topology
Star topology does not provide alternate paths for a device whose cable fails; that device loses all connectivity, even though other devices remain connected.
Trap 3: Bus topology
Bus topology has a single main cable; a break disrupts the entire network segment.
- A
Ring topology
Why wrong: Ring topology does not provide redundancy; a single cable break disrupts the entire network unless a dual ring is used, which is not specified.
- B
Star topology
Why wrong: Star topology does not provide alternate paths for a device whose cable fails; that device loses all connectivity, even though other devices remain connected.
- C
Hybrid topology
Hybrid topology can incorporate redundant elements (e.g., a mesh backbone) to provide multiple paths and maintain communication if one cable fails.
- D
Mesh topology
Mesh topology provides full redundancy with multiple connections, allowing communication via alternative paths if any single cable fails.
- E
Bus topology
Why wrong: Bus topology has a single main cable; a break disrupts the entire network segment.
