Komplette Lösung: https://itexamanswers.net/11-10-1-packet-tracer-design-and-implement-a-vlsm-addressing-scheme-instructions-answer.html

Szenario 1

Zielsetzung:

In this lab you will design a VLSM addressing scheme given a network address and host requirements. You will configure addressing on routers, switches, and network hosts.

Design a VLSM IP addressing scheme given requirements.
Configure addressing on network devices and hosts.
Verify IP connectivity.
Troubleshoot connectivity issues as required.

Requirements

Host Requirements:

LAN	Number of Addresses Required
HQ-1 LAN	11
HQ-2 LAN	28
Remote-1 LAN	5
Remote-2 LAN	47

Design Requirements:

Create the addressing design. Follow guidelines provided in the curriculum regarding the order of the subnets.
The subnets should be contiguous. There should be no unused address space between subnets.
Provide the most efficient subnet possible for the point-to-point link between the routers.
Assign the subnets in the order of the number of hosts from the greatest to the least.
Document your design in a table such as the one below.

Subnet Description	Number of Hosts Needed	Network Address (CIDR)	First Usable Host Address	Broadcast Address
Remote-2 LAN	47	10.1.1.0/26	10.1.1.1	10.1.1.63
HQ-2 LAN	28	10.1.1.64/27	10.1.1.65	10.1.1.95
HQ-1 LAN	11	10.1.1.96/28	10.1.1.97	10.1.1.111
Remote-1 LAN	5	10.1.1.112/29	10.1.1.113	10.1.1.119
WAN Link	2	10.1.48.120/30	10.1.1.121	10.1.1.123

Configuration Requirements:

Note: You will configure addressing on all devices and hosts in the network.

Assign the first usable IP addresses in the appropriate subnets to HQ for the two LAN links and the WAN link.
Assign the first usable IP addresses in the appropriate subnets to Remote for the two LANs links. Assign the last usable IP address for the WAN link.
Assign the second usable IP addresses in the appropriate subnets to the switches.
The switch management interface should be reachable from hosts on all of the LANs.
Assign the last usable IP addresses in the appropriate subnets to the hosts.
