300-410 Practice Question: Which TWO commands can be used to verify the…
Which TWO commands can be used to verify the configured AAA authentication method lists on a Cisco IOS-XE device? (Choose TWO.)
⚠ Common exam trap
Cisco often tests the exact command syntax, and the trap here is that candidates confuse 'show aaa method-lists' with non-existent commands like 'show aaa authentication' or 'show authentication method-lists', or they forget that 'show running-config | include aaa authentication' is a valid verification method.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
show aaa method-lists
'show aaa method-lists' directly displays all configured AAA authentication, authorization, and accounting method lists, including the default lists and any custom lists. Option C is correct because 'show running-config | include aaa authentication' filters the running configuration to show only lines containing 'aaa authentication', which explicitly lists the authentication method lists configured. Both commands provide a reliable way to verify the AAA authentication method lists on a Cisco IOS-XE device.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
show aaa
Why it's wrong here
This command displays AAA process information and statistics, but not the configured method lists; use 'show aaa method-lists' instead.
- ✓
show aaa method-lists
Why this is correct
This command displays all configured AAA method lists for authentication, authorization, and accounting.
- ✓
show running-config | include aaa authentication
Why this is correct
This filters the running configuration to show lines containing 'aaa authentication', which includes all authentication method list definitions.
- ✗
show aaa authentication
Why it's wrong here
This command does not exist; the correct command to view authentication method lists is 'show aaa method-lists authentication'.
- ✗
show authentication method-lists
Why it's wrong here
This command does not exist; AAA method lists are displayed using 'show aaa method-lists'.
Quick reference
AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
