The answer is to remove the 'authentication periodic' command from the interface configuration. This command explicitly enables periodic reauthentication on a port, forcing the client to reauthenticate at the default interval of one hour even when the session remains active. By removing it, you disable this automatic timer, so reauthentication only occurs when triggered by a change in the endpoint state, such as a link bounce or a new supplicant. On the Cisco SCOR 350-701 exam, this tests your understanding of 802.1X port-based authentication parameters, often appearing in a CLI exhibit where you must identify the command causing unwanted reauthentication. A common trap is confusing the 'authentication periodic' command with the 'authentication timer reauthenticate' command—the former enables the feature, while the latter sets the interval once enabled. Remember the memory tip: "Periodic means perpetual; remove it to stop the repeat."
350-701 Practice Question: Secure Network Access, Visibility and Enforcement
This 350-701 practice question tests your understanding of secure network access, visibility and enforcement. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Refer to the exhibit. An engineer configures this interface for 802.1X. Users report that after successful authentication, they are forced to reauthenticate every hour even though the authentication session is still active. What configuration change should be made to prevent reauthentication unless triggered by a change?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Remove 'authentication periodic'.
Option A is correct. The 'authentication periodic' command enables periodic reauthentication. Removing it stops automatic reauthentication. Option B is incorrect because setting the timer to 0 is invalid. Option C is incorrect because increasing the tx-period affects initial timeout, not reauthentication. Option D is incorrect because it configures server dead action, not reauthentication behavior.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Increase 'dot1x timeout tx-period' to 60.
Why it's wrong here
The tx-period controls retransmission of EAP packets, not reauthentication frequency.
✗
Change 'authentication timer reauthenticate' to 0.
Why it's wrong here
Setting the timer to 0 is not supported; it would likely default to the standard value.
✓
Remove 'authentication periodic'.
Why this is correct
Removing this command disables periodic reauthentication.

✗
Add 'authentication event server dead action authorize'.
Why it's wrong here
This command handles cases when the RADIUS server is unavailable, not periodic reauthentication.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 350-701 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
