VLANs 43 — HR (14) and Guests (15)
Enterprise Beginner 5 devices 6 checked tasks 100 points Free lab
One switch, two departments. Create VLAN 14 (HR) and VLAN 15 (GUESTS), put Fa0/1-2 in the first and Fa0/3-4 in the second, and prove the pair in each VLAN still reaches each other. You build it in a browser, type real commands at each device, and every task below is
checked against the running configuration — so you find out it is wrong before anybody else does.
Open this lab in the simulator
The simulator runs in your browser with nothing to install. This is a free lab: it stays open on the free plan. It needs an account, which keeps your progress.
The scenario
One switch, two departments. Create VLAN 14 (HR) and VLAN 15 (GUESTS), put Fa0/1-2 in the first and Fa0/3-4 in the second, and prove the pair in each VLAN still reaches each other.
Your role: a network engineer on the enterprise team. Level: Beginner Done when: all 6 goals show as passed (100 points).
Network status
Devices: 1 switch, 4 PCs, cabled as drawn. No Layer 1 or Layer 2 faults: every link is connected and up. HR-1 is a host with 192.168.62.11/24. HR-2 is a host with 192.168.62.12/24. Guests-1 is a host with 192.168.162.21/24. Guests-2 is a host with 192.168.162.22/24. SW-Aizawl starts with an empty configuration. Known problems
None: nothing is misconfigured. The network is simply not finished: what the goals list is what you have to build or secure. Goals
VLAN 14 exists (10 pts) VLAN 15 exists (10 pts) Fa0/1 and Fa0/2 are access ports in VLAN 14 (25 pts) Fa0/3 and Fa0/4 are access ports in VLAN 15 (25 pts) The HR PCs reach each other (15 pts) The Guests PCs reach each other (15 pts) The activity, in order
VLAN 14 exists Why: A port assigned to a VLAN that does not exist carries nothing. Verify with: show vlan brief VLAN 15 exists Why: A port assigned to a VLAN that does not exist carries nothing. Verify with: show vlan brief Fa0/1 and Fa0/2 are access ports in VLAN 14 Why: A VLAN is a separate broadcast domain; the port’s VLAN decides which devices can talk without a router. Verify with: show vlan brief Fa0/3 and Fa0/4 are access ports in VLAN 15 Why: A VLAN is a separate broadcast domain; the port’s VLAN decides which devices can talk without a router. Verify with: show vlan brief The HR PCs reach each other Why: A ping needs a route in BOTH directions. This is the end-to-end proof that everything before it worked. Verify with: ping 192.168.62.12 The Guests PCs reach each other Why: A ping needs a route in BOTH directions. This is the end-to-end proof that everything before it worked. Verify with: ping 192.168.162.22 Tips
Work in the order given: later goals depend on the earlier ones. After every change, run the verify command before moving on; do not guess. Stuck? Read the verify output first. It names the interface, neighbour or route that is wrong. Common mistake: Assigning a port to a VLAN that does not exist (older IOS) or forgetting switchport mode access Common mistake: Expecting different VLANs to talk without a router Common mistake: Typing the wrong range Why this matters
A VLAN is a broadcast domain defined in the switch, not by cables. Putting departments in separate VLANs keeps their broadcasts, and their mistakes, apart.
What you will be able to do
Create and name VLANs
Assign access ports to a VLAN
Verify with show vlan brief

What is configured at the start
Nothing is configured to start with beyond the addresses above: you build the configuration from a clean start.
Tasks, and how each one is checked
Every task is decided by reading the live network — a neighbour in FULL, a ping that succeeds, a line in the running configuration — not by looking for a keyword you typed. The same command shows you what the lab sees.
# Task Pts How to verify it yourself
1 VLAN 14 exists 10 On SW-Aizawl: show vlan brief lists VLAN 14. 2 VLAN 15 exists 10 On SW-Aizawl: show vlan brief lists VLAN 15. 3 Fa0/1 and Fa0/2 are access ports in VLAN 14 25 On SW-Aizawl: show vlan brief — Fa0/1 is an access port in VLAN 14. and On SW-Aizawl: show vlan brief — Fa0/2 is an access port in VLAN 14. 4 Fa0/3 and Fa0/4 are access ports in VLAN 15 25 On SW-Aizawl: show vlan brief — Fa0/3 is an access port in VLAN 15. and On SW-Aizawl: show vlan brief — Fa0/4 is an access port in VLAN 15. 5 The HR PCs reach each other 15 On HR-1: ping 192.168.62.12 must succeed. 6 The Guests PCs reach each other 15 On Guests-1: ping 192.168.162.22 must succeed.
Stuck? Ask the coach
Tell the coach what you see or what you tried. It gives you a hint, not the answer, the way a senior engineer would. Included with a free trial or any plan.

Common mistakes
Assigning a port to a VLAN that does not exist (older IOS) or forgetting switchport mode access
Expecting different VLANs to talk without a router
Typing the wrong range
Reference solution
Try it yourself first — the lab checks your work either way. This is one configuration that makes every task pass, device by device:
SW-Aizawl vlan 14
name HR
exit
vlan 15
name GUESTS
exit
interface range fa0/1 - 2
switchport mode access
switchport access vlan 14
exit
interface range fa0/3 - 4
switchport mode access
switchport access vlan 15
exit Where this is examined
CCNA 2.0 Network Access (VLANs); Network+ 2.3 switching.
