Complete step-by-step Packet Tracer (.PKA) lab solution for WGU D325 (Networks / CCNA 200-301 v1.1) Complete Lab & OA Practice Exam (Part 1). Includes the Topology Addressing Table, Missing Score Checklist (95% or 98% -> 100% Fix), multi-device Cisco IOS CLI scripts, and 10 interactive lab verification questions.
1. Topology & Addressing Table (WGU-D325-LAB1)
| Device | Interface | IP Address | Subnet Mask | Gateway |
|---|---|---|---|---|
| Edge_Router | S0/0/0 & S0/0/1 | 10.10.10.1 | 255.255.255.252 | ISP1 / ISP2 |
| ISP1_Router | G0/0 | 2001:DB8:A:2::1/64 | 255.255.255.252 | ISP1 / ISP2 |
⚠️ Stuck at 95% or 98% in Packet Tracer? (3 Hidden Grader Checks)
1. Check #1: Forgot 'ipv6 unicast-routing' in global configuration mode before entering IPv6 routes.
2. Check #2: Used wrong Administrative Distance (AD) for the floating static route (must be AD 5).
3. Check #3: Created recursive static route instead of directly attached static route on Edge_Router.
2. Complete Multi-Device Cisco IOS CLI Solution (WGU-D325-LAB1)
Edge_Router Configuration Script
Edge_Router — IOS CLI
enable configure terminal ipv6 unicast-routing ip route 0.0.0.0 0.0.0.0 Serial0/0/0 ip route 0.0.0.0 0.0.0.0 Serial0/0/1 5 ipv6 route ::/0 2001:DB8:A:2::1 ipv6 route ::/0 2001:DB8:A:3::1 5 end copy running-config startup-config
ISP1_Router Configuration Script
ISP1_Router — IOS CLI
enable configure terminal ipv6 unicast-routing ip route 192.168.1.0 255.255.255.0 Serial0/0/0 ipv6 route 2001:DB8:1:1::/64 2001:DB8:A:2::2 end copy running-config startup-config
3. Practical Lab Verification Quiz (10 Interactive Questions)
Lab Question 1While configuring WGU-D325-LAB1 in Packet Tracer, your score is stuck at 95% or 98% even though pings succeed. What is the #1 configuration item missed?
✔ Correct Answer: A. Forgot 'ipv6 unicast-routing' in global configuration mode before entering IPv6 routes.
Lab Verification Note: Always verify with
show ip route static | show ipv6 route static and save configuration to NVRAM.Lab Question 2Refer to the Addressing Table in WGU-D325-LAB1. Which command sequence configures Edge_Router (S0/0/0 & S0/0/1)?
✔ Correct Answer: B. ip address 10.10.10.1 255.255.255.252 and no shutdown
Lab Verification Note: Always verify with
show ip route static | show ipv6 route static and save configuration to NVRAM.Lab Question 3During Part 2 of WGU-D325-LAB1, which second common mistake prevents reaching 100%?
✔ Correct Answer: C. Used wrong Administrative Distance (AD) for the floating static route (must be AD 5).
Lab Verification Note: Always verify with
show ip route static | show ipv6 route static and save configuration to NVRAM.Lab Question 4Which Cisco IOS verification command confirms operational status for WGU-D325-LAB1?
✔ Correct Answer: A. show ip route static | show ipv6 route static
Lab Verification Note: Always verify with
show ip route static | show ipv6 route static and save configuration to NVRAM.Lab Question 5What is the third critical grader check required before submitting WGU-D325-LAB1?
✔ Correct Answer: D. Created recursive static route instead of directly attached static route on Edge_Router.
Lab Verification Note: Always verify with
show ip route static | show ipv6 route static and save configuration to NVRAM.Lab Question 6What happens if the Native VLAN is mismatched on an 802.1Q trunk link in WGU-D325-LAB1?
✔ Correct Answer: B. CDP logs native VLAN mismatch alerts and PVST+ blocks the inconsistent VLAN.
Lab Verification Note: Always verify with
show ip route static | show ipv6 route static 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 route static | show ipv6 route static and save configuration to NVRAM.Lab Question 8Why must you execute 'copy running-config startup-config' before submitting WGU-D325-LAB1 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 route static | show ipv6 route static 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 route static | show ipv6 route static 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 route static | show ipv6 route static and save configuration to NVRAM.
