Refer to the exhibit:
Which three statements correctly describe Network Device A? (Choose three.)
A.
With a network wide mask of 255.255.255.128, each interface does not require an IP address.
B.
With a network wide mask of 255.255.255.128, each interface does require an IP address on a unique IP subnet.
C.
With a network wide mask of 255.255.255.0, must be a Layer 2 device for the PCs to communicate with each other.
D.
With a network wide mask of 255.255.255.0, must be a Layer 3 device for the PCs to communicate with each other.
E.
With a network wide mask of 255.255.254.0, each interface does not require an IP address.
i did not understand this………..how to calculate this ?
Explanation:
1. if the PCs has the network mask /24 the will then be in diferent subnetwroks that mean they need a Layer3 device(router) to communcatte with each others.
2. if the Interfaces of the Networks device have a subnet 255.255.255.128 they have to be in diffirent subnets exp: 10.1.0.0/25 and 10.1.0.128/25
3. if we use a Mask of 255.255.254.0 we don t have to use a router anymore and we can take switch instead. Becaus the network /22 include both 10.1.0.36 and 10.1.1.70
