Complete step-by-step Packet Tracer (.PKA) lab solution for CCNA 2 SRWE v7.02 / v8 Practice PT Skills Assessment (PTSA Part 1 & 2) Full .PKA Solution. 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 (SRWE-PTSA-1)
| 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 (SRWE-PTSA-1)
Core_R1 Configuration Script
Core_R1 — IOS CLI

3. Practical Lab Verification Quiz (10 Interactive Questions)
Lab Question 1While configuring SRWE-PTSA-1 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 SRWE-PTSA-1. 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 SRWE-PTSA-1, 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 SRWE-PTSA-1?
✔ 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 SRWE-PTSA-1?
✔ 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 SRWE-PTSA-1?
✔ 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 SRWE-PTSA-1 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.
