Q38

An organization requires a range of IP address to assign one to each of its $1500$ computers. The organization has approached an Internet Service Provider (ISP) for this task. The ISP uses CIDR and serves the requests from the available IP address space $202.61.0.0/17$. The ISP wants to assign an address space to the organization which will minimize the number of routing entries in the ISP’s router using route aggregation. Which of the following address spaces are potential candidates from which the ISP can allot any one to the organization? $\text{I}$ and $\text{II}$ only $\text{II}$ and $\text{III}$ only $\text{III}$ and $\text{IV}$ only $\text{I}$ and $\text{IV}$ only
