Complete step-by-step Packet Tracer (.PKA) lab solution for CCNA 200-301 v1.1 Performance-Based Lab (PBQ Simlet 2): 802.1Q VLAN Trunking & LACP EtherChannel. Includes the Topology Addressing Table, Missing Score Checklist (Pearson VUE PBQ -> 100% Fix), multi-device Cisco IOS CLI scripts, and 10 interactive lab verification questions.
1. Topology & Addressing Table (PBQ-LAB-2)
| Device | Interface | IP Address | Subnet Mask | Gateway |
|---|---|---|---|---|
| Dist_SW1 | Port-channel 1 | 802.1Q Trunk | Allowed: 10,20,99 | Native VLAN 99 |
| Access_SW2 | Port-channel 1 | 802.1Q Trunk | Allowed: 10,20,99 | Native VLAN 99 |
⚠️ Stuck at Pearson VUE PBQ in Packet Tracer? (3 Hidden Grader Checks)
1. Check #1: Never use 'mode on' when asked for IEEE 802.3ad LACP (must use 'mode active' / 'passive').
2. Check #2: Ensure Native VLAN 99 matches on both physical member ports AND Port-channel1.
3. Check #3: Verify that Port-channel displays '(SU)' in 'show etherchannel summary'.
2. Complete Multi-Device Cisco IOS CLI Solution (PBQ-LAB-2)
Dist_SW1 Configuration Script
Dist_SW1 — IOS CLI
enable configure terminal vlan 10,20,99 interface range g0/1 - 2 switchport mode trunk switchport trunk native vlan 99 switchport trunk allowed vlan 10,20,99 channel-group 1 mode active interface port-channel 1 switchport mode trunk switchport trunk native vlan 99 switchport trunk allowed vlan 10,20,99 end copy running-config startup-config
Access_SW2 Configuration Script
Access_SW2 — IOS CLI
enable configure terminal vlan 10,20,99 interface range g0/1 - 2 switchport mode trunk switchport trunk native vlan 99 switchport trunk allowed vlan 10,20,99 channel-group 1 mode passive interface port-channel 1 switchport mode trunk switchport trunk native vlan 99 switchport trunk allowed vlan 10,20,99 end copy running-config startup-config
3. Practical Lab Verification Quiz (10 Interactive Questions)
Lab Question 1While configuring PBQ-LAB-2 in Packet Tracer, your score is stuck at Pearson VUE PBQ even though pings succeed. What is the #1 configuration item missed?
✔ Correct Answer: A. Never use 'mode on' when asked for IEEE 802.3ad LACP (must use 'mode active' / 'passive').
Lab Verification Note: Always verify with
show etherchannel summary | show interfaces trunk and save configuration to NVRAM.Lab Question 2Refer to the Addressing Table in PBQ-LAB-2. Which command sequence configures Dist_SW1 (Port-channel 1)?
✔ Correct Answer: B. ip address 802.1Q Trunk Allowed: 10,20,99 and no shutdown
Lab Verification Note: Always verify with
show etherchannel summary | show interfaces trunk and save configuration to NVRAM.Lab Question 3During Part 2 of PBQ-LAB-2, which second common mistake prevents reaching 100%?
✔ Correct Answer: C. Ensure Native VLAN 99 matches on both physical member ports AND Port-channel1.
Lab Verification Note: Always verify with
show etherchannel summary | show interfaces trunk and save configuration to NVRAM.Lab Question 4Which Cisco IOS verification command confirms operational status for PBQ-LAB-2?
✔ Correct Answer: A. show etherchannel summary | show interfaces trunk
Lab Verification Note: Always verify with
show etherchannel summary | show interfaces trunk and save configuration to NVRAM.Lab Question 5What is the third critical grader check required before submitting PBQ-LAB-2?
✔ Correct Answer: D. Verify that Port-channel displays '(SU)' in 'show etherchannel summary'.
Lab Verification Note: Always verify with
show etherchannel summary | show interfaces trunk and save configuration to NVRAM.Lab Question 6What happens if the Native VLAN is mismatched on an 802.1Q trunk link in PBQ-LAB-2?
✔ Correct Answer: B. CDP logs native VLAN mismatch alerts and PVST+ blocks the inconsistent VLAN.
Lab Verification Note: Always verify with
show etherchannel summary | show interfaces trunk and save configuration to NVRAM.Lab Question 7If a switch port configured with Port Security violates the max MAC count in default mode, what state does it enter?
✔ Correct Answer: C. err-disabled (requires shutdown and no shutdown to recover)
Lab Verification Note: Always verify with
show etherchannel summary | show interfaces trunk and save configuration to NVRAM.Lab Question 8Why must you execute 'copy running-config startup-config' before submitting PBQ-LAB-2 or a 200-301 PBQ Simlet?
✔ Correct Answer: A. To save active RAM configuration into non-volatile NVRAM so grading scripts score it.
Lab Verification Note: Always verify with
show etherchannel summary | show interfaces trunk and save configuration to NVRAM.Lab Question 9If a router learns a /24 route via OSPF (AD 110) and a Floating Static Route configured with AD 5, which enters the routing table?
✔ Correct Answer: B. The Floating Static Route (AD 5) because 5 is lower than OSPF AD 110.
Lab Verification Note: Always verify with
show etherchannel summary | show interfaces trunk and save configuration to NVRAM.Lab Question 10Where should an Extended IPv4 ACL (100-199) be placed according to Cisco best practices?
✔ Correct Answer: D. As close to the SOURCE of the traffic as possible.
Lab Verification Note: Always verify with
