5 bits are necessary to create up to 30 subnets.
No
Depending on class of network you are planning to use. For class C you can create much more then that (and for the most case for others too).
Subnets allow to isolate traffic within a subnet. It is beneficial not only from security perspective but also from performance.

What if your company is assigned a network address of 150.50.0.0 you need to create 4 subnets all having access to the internet what is the correct subnet mask for the network
That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.

192 is equal to 2 bits borrowed 2^2 = 4 the number of subnets and host are 64 because 2 bits borrowed from the 8 bits of a class C network is 6, therfore 2^6 = 64.
