Consider the incomplete 6-node network shown below, with the given link costs. 2 X W Z Consider the completed table below, which calculates the shortest distance to all nodes from X: | Node | Shortest distance from X | Previous Node | XDVAN> U W Y Z 024667 n/a **D*** X U X W 1. For link X, what is the cost associated with this link? If the answer can't be determined given the information, respond with 'n/a' 2. For link Y, what is the cost associated with this link? If the answer can't be determined given the information, respond with 'n/a' Q2. Consider the router and the two attached subnets below (A and B). The number of hosts is also shown below. The subnets share the 24 high-order bits of the address space: 172.19.32.0/24 A 172.19.32.0/24 BB 119 hosts 107 hosts Assign subnet addresses to each of the subnets (A and B) so that the amount of address space assigned is minimal, and at the same time leaving the largest possible contiguous address pace available for assignment if a new subnet were to be added. Then answer the questions below. 1. Is the address space public or private? 2. How many hosts can there be in this address space? 3. What is the subnet address of subnet A? (CIDR notation) 4. What is the broadcast address of subnet A? 5. What is the starting address of subnet A? 6. What is the ending address of subnet A? 7. What is the subnet address of subnet B? (CIDR notation) 8. What is the broadcast address of subnet B? 9. What is the starting address of subnet B? 10. What is the ending address of subnet B?
