Tasks

All physical cabling is in place. A company plans to deploy 64 new sites. The sites will utilize both IPv4 and IPv6 networks.

1. Subnet 10.30.64.0/19 to meet the subnet requirements and maximize the number of hosts
• Using the second subnet
- Assign the first usable IP address to e0/0 on Sw101
- Assign the last usable IP address to e0/0 on Sw102

2. Subnet 2001:db8::/56 to meet the subnet requirements and maximize the number of hosts
• Using the second subnet
- Assign an IPv6 GUA using a unique 64-Bit interface identifier on e0/0 on Sw101
- Assign an IPv6 GUA using a unique 64-Bit interface identifier on e0/0 on Sw102

we have a /56 and we must divide it into 64 equal network 64 = 2^6 we can have 64 equal network by using a /62 cuz 56+6 = 62

The question does not require "ip routing" and "ipv6 unicast-routing" be enabled. Without enabling them, the v4 and v6 addresses are still able to be assigned to the interfaces. In this case, do we need to enable ip routing and ipv6 unicast-routing? What's Cisco's scoring standard?

here's my answer and tutorial: numbers in the brackets is binary convert to IPv4 binary 10.30.[010] need 6 bits to contain 64 sites, this also is first subnet 10.30.[010|00000].[0] so new mask is 255.255.255.128, then add 1 in last bit of the mask 10.30.[010|00000].[1] add 1 in host bit and convert to decimal, you have first usable IP address 10.30.64.129 last usable IP address is 10.30.64.254

IPv4: Use /26 for 64 sites, assign 10.30.64.65 to Sw101, 10.30.64.126 to Sw102. IPv6: Use 2001:DB8:0:1::/64, enable EUI-64 on both switches. put the switchport in layer3 mode: For Sw101: interface Ethernet0/0 no switchport ip address 10.30.64.65 255.255.255.192 ipv6 address 2001:DB8:0:1::/64 eui-64 no shutdown For Sw102: interface Ethernet0/0 no switchport ip address 10.30.64.126 255.255.255.192 ipv6 address 2001:DB8:0:1::/64 eui-64 no shutdown

i think this is the correct answer. Since we have 64 sites and subnet / 19 to maximise, 64 is 2^6, so add 6 to 19 to get /25 for each subnet. that will give 128 host for 64 sites with 10.30.64.0/25 as first subnet and 10.30.95.128/25 as last subnet

this is incorrect. You didnt even use "no switchport" command.
