- A
Enter global configuration mode, enter interface configuration mode, assign IPv4 address, exit to enable mode, ping IPv6 host
This sequence correctly follows the Cisco IOS-XE configuration steps: global config, interface config, IP address assignment, exit to enable mode, and then verification via ping to the IPv6 host.
- B
Enter interface configuration mode, assign IPv4 address, enter global configuration mode, exit to enable mode, ping IPv6 host
This is incorrect because you must be in global configuration mode before entering interface configuration mode. Skipping global config is not possible on Cisco IOS-XE.
- C
Enter global configuration mode, assign IPv4 address, enter interface configuration mode, exit to enable mode, ping IPv6 host
This is incorrect because the IPv4 address must be assigned under the interface configuration mode, not global configuration mode. The 'ip address' command is an interface subcommand.
- D
Enter global configuration mode, enter interface configuration mode, assign IPv4 address, ping IPv6 host, exit to enable mode
This is incorrect because the ping command is executed from enable mode, not from interface configuration mode. You must exit to enable mode before pinging.
Quick Answer
The correct order is to enter global configuration mode, then interface configuration mode, assign the IPv4 address, exit to enable mode, and finally ping the IPv6 host. This sequence is required because Cisco IOS-XE operates in a strict hierarchical command structure: you must first enter global configuration mode to unlock interface-level commands, then select the specific interface before you can apply the `ip address` command. After configuring IPv4, you must exit completely to enable mode (or privileged EXEC mode) because the `ping` command is only available at that level, not from interface configuration mode. On the CCNA 200-301 v2 exam, this drag-and-drop task tests your understanding of the IOS configuration hierarchy and the difference between configuring IPv4 and verifying IPv6 connectivity, often using an EUI-64 address. A common trap is trying to assign the IPv4 address in global config or pinging from interface mode—both are invalid. Memory tip: think “G-I-A-E-P” (Global, Interface, Address, Exit, Ping) to lock in the correct flow.
CCNA Network Infrastructure and Connectivity Practice Question
This 200-301 practice question tests your understanding of network infrastructure and connectivity. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Drag and drop the following steps into the correct order to configure an IPv4 address on a Cisco IOS-XE router interface, then verify the configuration with a ping to a host that uses an IPv6 EUI-64 address.

Correct answer & explanation
Enter global configuration mode, enter interface configuration mode, assign IPv4 address, exit to enable mode, ping IPv6 host
The correct sequence is to first enter global configuration mode, then interface configuration mode, assign the IPv4 address, exit completely to enable mode, and finally ping the IPv6 host. Option B is incorrect because you cannot enter interface configuration mode before global configuration mode; you must be in global config first. Option C is incorrect because you cannot assign an IPv4 address in global configuration mode; that command must be issued in interface configuration mode. Option D is incorrect because you cannot execute the ping command from interface configuration mode; you must exit to enable mode first.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related 200-301 questions on access control and AAA configuration.
