All physical cabling is in place. A company plans to deploy 32 new sites.
The sites will utilize both IPv4 and IPv6 networks.
1 . Subnet 172.25.0.0/16 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 Sw1O1
* Assign the last usable IP address to e0/0 on Sw102
2. Subnet to meet the subnet requirements and maximize
the number of hosts
c 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 eO/O on swi02

See the Explanation for the solution.
Explanation:
* To subnet 172.25.0.0/16 to meet the subnet requirements and maximize the number of hosts, you need to determine how many bits you need to borrow from the host portion of the address to create enough subnets for 32 sites. Since 32 is 2^5, you need to borrow 5 bits, which means your new subnet mask will be /21 or 255.255.248.0. To find the second subnet, you need to add the value of the fifth bit (32) to the third octet of the network address (0), which gives you 172.25.32.0/21 as the second subnet. The first usable IP address in this subnet is 172.25.32.1, and the last usable IP address is 172.25.39.254.
* To assign the first usable IP address to e0/0 on Sw101, you need to enter the following commands on the device console:
Sw101#configure terminal Sw101(config)#interface e0/0 Sw101(config-if)#ip address 172.25.32.1
255.255.248.0 Sw101(config-if)#no shutdown Sw101(config-if)#end
* To assign the last usable IP address to e0/0 on Sw102, you need to enter the following commands on the device console:
Sw102#configure terminal Sw102(config)#interface e0/0 Sw102(config-if)#ip address 172.25.39.254
255.255.248.0 Sw102(config-if)#no shutdown Sw102(config-if)#end
* To subnet an IPv6 GUA to meet the subnet requirements and maximize the number of hosts, you need to determine how many bits you need to borrow from the interface identifier portion of the address to create enough subnets for 32 sites. Since 32 is 2^5, you need to borrow 5 bits, which means your new prefix length will be /69 or ffff:ffff:ffff:fff8::/69 (assuming that your IPv6 GUA has a /64 prefix by default). To find the second subnet, you need to add the value of the fifth bit (32) to the fourth hextet of the network address (0000), which gives you xxxx:xxxx:xxxx:0020::/69 as the second subnet (where xxxx:xxxx:xxxx is your IPv6 GUA prefix). The first and last IPv6 addresses in this subnet are xxxx:
xxxx:xxxx:0020::1 and xxxx:xxxx:xxxx:0027:ffff:ffff:ffff:fffe respectively.
* To assign an IPv6 GUA using a unique 64-bit interface identifier on e0/0 on Sw101, you need to enter the following commands on the device console (assuming that your IPv6 GUA prefix is 2001:db8::/64):
Sw101#configure terminal Sw101(config)#interface e0/0 Sw101(config-if)#ipv6 address 2001:db8::20::1/69 Sw101(config-if)#no shutdown Sw101(config-if)#end
* To assign an IPv6 GUA using a unique 64-bit interface identifier on e0/0 on Sw102, you need to enter the following commands on the device console (assuming that your IPv6 GUA prefix is 2001:db8::/64):
Sw102#configure terminal Sw102(config)#interface e0/0 Sw102(config-if)#ipv6 address 2001:db8::27::fffe
/69 Sw102(config-if)#no shutdown Sw102(config-if)#end

Explanation:
Ansible:- uses SSH for remote device communication- uses YAML for fundamental configuration elements Chef:- uses TCP port 10002 for configuration push jobs- uses Ruby for fundamental configuration elements Puppet:- fundamental configuration elements are stored in a manifest- uses TCP 8140 for communication The focus of Ansible is to be streamlined and fast, and to require no node agent installation.Thus, Ansible performs all functions over SSH. Ansible is built on Python, in contrast to the Ruby foundation of Puppet and Chef.TCP port 10002 is the command port. It may be configured in the Chef Push Jobs configuration file .
This port allows Chef Push Jobs clients to communicate with the Chef Push Jobs server.Puppet is an open- source configuration management solution, which is built with Ruby and offers custom Domain Specific Language (DSL) and Embedded Ruby (ERB) templates to create custom Puppet language files, offering a declarative-paradigm programming approach.A Puppet piece of code is called a manifest, and is a file with .
pp extension.
