Complete step-by-step Packet Tracer (.PKA) lab solution for 17.8.2 Packet Tracer - ITN Skills Integration Challenge (IPv4/IPv6 & SSH .PKA Walkthrough). 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 (17.8.2)
| Device | Interface | IP Address | Subnet Mask | Gateway |
|---|---|---|---|---|
| Core_R1 | Loopback0 & G0/0 | 10.0.0.1 | 255.255.255.255 | OSPF Area 0 |
| Branch_R2 | G0/0 & G0/1 | 10.1.12.2 | 255.255.255.255 | OSPF Area 0 |
⚠️ Stuck at Pearson VUE PBQ in Packet Tracer? (3 Hidden Grader Checks)
1. Check #1: Always verify existing OSPF process ID first using 'show running-config | section ospf'.
2. Check #2: Use '/32' exact interface IP matching ('network 10.1.12.1 0.0.0.0 area 0').
3. Check #3: Always execute 'copy running-config startup-config' before clicking Next in the exam engine!
2. Complete Multi-Device Cisco IOS CLI Solution (17.8.2)
Core_R1 Configuration Script
Core_R1 — IOS CLI

3. Practical Lab Verification Quiz (10 Interactive Questions)
Lab Question 1While configuring 17.8.2 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. Always verify existing OSPF process ID first using 'show running-config | section ospf'.
Lab Verification Note: Always verify with
show ip ospf neighbor | show ip route ospf and save configuration to NVRAM.Lab Question 2Refer to the Addressing Table in 17.8.2. Which command sequence configures Core_R1 (Loopback0 & G0/0)?
✔ Correct Answer: B. ip address 10.0.0.1 255.255.255.255 and no shutdown
Lab Verification Note: Always verify with
show ip ospf neighbor | show ip route ospf and save configuration to NVRAM.Lab Question 3During Part 2 of 17.8.2, which second common mistake prevents reaching 100%?
✔ Correct Answer: C. Use '/32' exact interface IP matching ('network 10.1.12.1 0.0.0.0 area 0').
Lab Verification Note: Always verify with
show ip ospf neighbor | show ip route ospf and save configuration to NVRAM.Lab Question 4Which Cisco IOS verification command confirms operational status for 17.8.2?
✔ Correct Answer: A. show ip ospf neighbor | show ip route ospf
Lab Verification Note: Always verify with
show ip ospf neighbor | show ip route ospf and save configuration to NVRAM.Lab Question 5What is the third critical grader check required before submitting 17.8.2?
✔ Correct Answer: D. Always execute 'copy running-config startup-config' before clicking Next in the exam engine!
Lab Verification Note: Always verify with
show ip ospf neighbor | show ip route ospf and save configuration to NVRAM.Lab Question 6What happens if the Native VLAN is mismatched on an 802.1Q trunk link in 17.8.2?
✔ Correct Answer: B. CDP logs native VLAN mismatch alerts and PVST+ blocks the inconsistent VLAN.
Lab Verification Note: Always verify with
show ip ospf neighbor | show ip route ospf 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 ip ospf neighbor | show ip route ospf and save configuration to NVRAM.Lab Question 8Why must you execute 'copy running-config startup-config' before submitting 17.8.2 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 ip ospf neighbor | show ip route ospf 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 ip ospf neighbor | show ip route ospf 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
show ip ospf neighbor | show ip route ospf and save configuration to NVRAM.
