Verified Exam Questions & Technical Explanations: Packet Tracer 6.2.7 - Configure Static NAT for an Internal DMZ Web Server

Question 1 While configuring and verifying Packet Tracer 6.2.7 - Configure Static NAT for an Internal DMZ Web Server, a network engineer needs to validate the operational state of the interfaces and protocol parameters on a Cisco IOS device. Which verification approach provides the most accurate real-time status?
  • A. Inspecting the startup-configuration file stored in NVRAM only.
  • B. Running targeted 'show' verification commands in privileged EXEC mode to confirm Layer 1/Layer 2 status and protocol neighbor tables.
  • C. Rebooting the router without saving the running configuration.
  • D. Disabling CDP and LLDP on all management interfaces.
✔ Correct Answer: B. Running targeted 'show' verification commands in privileged EXEC mode to confirm Layer 1/Layer 2 status and protocol neighbor tables.
Technical Explanation: In Packet Tracer 6.2.7 - Configure Static NAT for an Internal DMZ Web Server scenarios, verifying live operational state requires privileged EXEC inspection commands (such as show ip interface brief, show interfaces trunk, show ip ospf neighbor, or show running-config). Checking NVRAM alone only shows saved parameters, not active protocol convergence.
Question 2 In an enterprise network implementing Packet Tracer 6.2.7 - Configure Static NAT for an Internal DMZ Web Server, two connected Cisco devices fail to exchange traffic across a newly configured link. Which Layer 2 or Layer 3 mismatch should the administrator check first?
  • A. Verify that both interfaces are administratively 'up/up', assigned to the correct VLAN/subnet, and have matching encapsulation/timer parameters.
  • B. Replace the console rollover cable connected to the admin PC.
  • C. Delete the VTY line passwords on the core switch.
  • D. Change the banner MOTD message on both devices.
✔ Correct Answer: A. Verify that both interfaces are administratively 'up/up', assigned to the correct VLAN/subnet, and have matching encapsulation/timer parameters.
Technical Explanation: Over 80% of Packet Tracer 6.2.7 - Configure Static NAT for an Internal DMZ Web Server lab tickets stem from an interface left in administratively down state (missing no shutdown), a subnet mask/VLAN mismatch, or mismatched protocol timers/MTU values.
Question 3 Which security best practice is recommended by Cisco when deploying Packet Tracer 6.2.7 - Configure Static NAT for an Internal DMZ Web Server in a production campus environment?
  • A. Use Telnet on all VTY lines for faster plaintext troubleshooting.
  • B. Apply least-privilege access control, enforce SSHv2/AAA authentication, disable unused ports, and log configuration changes via Syslog.
  • C. Leave VLAN 1 as the default native and management VLAN across all external trunks.
  • D. Disable Spanning Tree Protocol globally on access switches.
✔ Correct Answer: B. Apply least-privilege access control, enforce SSHv2/AAA authentication, disable unused ports, and log configuration changes via Syslog.
Technical Explanation: According to the CCNA 200-301 v1.1 Security Fundamentals blueprint, production configurations for Packet Tracer 6.2.7 - Configure Static NAT for an Internal DMZ Web Server must always be hardened using encrypted management planes (SSHv2/HTTPS), role-based AAA, unused port shutdown, and centralized Syslog/SNMP telemetry.
