The answer is to use stronger or additional authentication controls to improve remote administrative access security. This is correct because the core goal is to move beyond a simple, static password toward a more robust authentication framework, which is precisely what Cisco AAA (Authentication, Authorization, and Accounting) using TACACS+ or RADIUS provides. These protocols centralize user credentials and allow for granular control, while also supporting encryption of the entire authentication process—TACACS+ encrypts all traffic, making it ideal for securing CLI access. On the CCNA 200-301 v2 exam, this question tests your understanding that AAA is the foundational method for enhancing remote access security, not just adding ACLs or changing protocols. A common trap is confusing authorization (what you can do) with authentication (who you are), or thinking that SSH alone is sufficient without a stronger authentication mechanism. Memory tip: AAA stands for "All Access Authenticated"—if you want to secure remote CLI, you need AAA with TACACS+ or RADIUS, not just a password.

Correct answer & explanation
✓
Use stronger or additional authentication controls to improve remote administrative access security
The goal is to strengthen authentication beyond a simple password. Cisco AAA (Authentication, Authorization, and Accounting) using TACACS+ or RADIUS provides stronger, centralized authentication. Secure Shell (SSH) with key-based or two-factor authentication also enhances security. Option A correctly describes this concept, while the other options either weaken security (B, D) or address access control via ACLs, which does not improve the authentication factor itself (C).
Key principle: Strong remote administrative access requires authentication methods that go beyond simple username and password combinations to prevent unauthorized access.

✗
Replace SSH with Telnet to simplify troubleshooting
Why it's wrong here
This is wrong because Telnet weakens management security by sending traffic in clear text.
When this WOULD be correct
This option could be correct in a scenario where the question asks about troubleshooting network connectivity issues and emphasizes ease of access for administrators. If the focus were on simplifying access for troubleshooting rather than security, replacing SSH with Telnet might be considered appropriate.
✗
Configure an extended ACL to limit remote access to specific source IP addresses
Why it's wrong here
This is wrong because removing authentication undermines security.
When this WOULD be correct
In a hypothetical exam scenario where the question asks about a system that requires immediate access without any credentials for emergency situations, disabling authentication could be considered correct to prevent lockouts during critical failures.
✗
Disable password authentication and rely solely on device location in the network
Why it's wrong here
This is wrong because switch trunking is unrelated to stronger remote administrative authentication.
When this WOULD be correct
In a question focused on network design where the goal is to optimize bandwidth and support multiple VLANs on a single connection, selecting trunk ports could be the correct answer. For instance, if the question asks how to efficiently manage VLAN traffic in a switched network environment, trunking would be appropriate.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.

Why this is correct
This is correct because the goal is to improve authentication strength rather than rely only on a weak single factor.
✗Replace SSH with Telnet to simplify troubleshootingWrong answer — click to see why▾
Why this is wrong here
Telnet transmits credentials in plaintext, making it less secure than SSH and opposite to the goal of stronger authentication.
★ When this WOULD be the correct answer
This option could be correct in a scenario where the question asks about troubleshooting network connectivity issues and emphasizes ease of access for administrators. If the focus were on simplifying access for troubleshooting rather than security, replacing SSH with Telnet might be considered appropriate.
Why candidates choose this
Candidates may choose this option due to a misunderstanding of the trade-offs between security and ease of access, believing that simpler protocols like Telnet could facilitate quicker troubleshooting without recognizing the security implications.
✗Configure an extended ACL to limit remote access to specific source IP addressesWrong answer — click to see why▾
Why this is wrong here
While ACLs can limit which hosts can connect, they do not strengthen the authentication mechanism itself; they only restrict source addresses.
★ When this WOULD be the correct answer
In a hypothetical exam scenario where the question asks about a system that requires immediate access without any credentials for emergency situations, disabling authentication could be considered correct to prevent lockouts during critical failures.
Why candidates choose this
Candidates might be tempted by the idea of avoiding lockouts, especially in high-pressure environments where quick access is crucial, leading them to overlook the severe security implications of disabling authentication.
✗Disable password authentication and rely solely on device location in the networkWrong answer — click to see why▾
Why this is wrong here
Relying solely on location removes all credential verification, making the device vulnerable to unauthorized access from allowed locations.
★ When this WOULD be the correct answer
In a question focused on network design where the goal is to optimize bandwidth and support multiple VLANs on a single connection, selecting trunk ports could be the correct answer. For instance, if the question asks how to efficiently manage VLAN traffic in a switched network environment, trunking would be appropriate.
Why candidates choose this
Candidates may be tempted by this option because they associate trunk ports with advanced network configurations, mistakenly believing that they enhance overall security by managing multiple VLANs, rather than focusing on authentication methods.

Common exam traps
Common exam trap: answer the scenario, not the keyword
A common trap is thinking that limiting access with an ACL (option C) satisfies the goal, but ACLs restrict source addresses, not strengthen the authentication process. Another trap is confusing stronger authentication with simpler troubleshooting (B) or location-based trust (D).
Detailed technical explanation
How to think about this question
Remote administrative access to network devices requires robust authentication mechanisms to prevent unauthorized entry. Plain usernames and passwords represent a single-factor authentication method, which is vulnerable to interception, guessing, or brute-force attacks. Strengthening authentication involves implementing multi-factor authentication (MFA) or stronger cryptographic methods to verify user identity beyond just a password. This approach enhances security by requiring additional proof, such as a token or biometric factor, making unauthorized access significantly more difficult.
In Cisco networking and the CCNA 200-301 context, securing remote access commonly involves replacing insecure protocols like Telnet with SSH, which encrypts credentials and session data. Beyond encryption, administrators should deploy stronger authentication controls such as TACACS+ or RADIUS servers, or enable multi-factor authentication where supported. The decision process focuses on enhancing the authentication layer rather than disabling it or weakening it by using less secure protocols or removing authentication entirely.
A common exam trap is confusing protocol choice with authentication strength. For example, switching from SSH to Telnet reduces encryption and security, which contradicts the goal of stronger protection. Similarly, disabling authentication to avoid lockouts undermines security principles. Practically, Cisco devices support multiple authentication methods, and understanding when to apply stronger or additional controls is critical for both exam success and real-world network security.
KKey Concepts to Remember
Strong remote administrative access requires authentication methods that go beyond simple username and password combinations to prevent unauthorized access.
Cisco devices support secure protocols like SSH that encrypt credentials, which is essential for protecting remote management sessions.
Multi-factor authentication adds an additional verification layer, significantly increasing the security of remote access to network devices.
Disabling authentication removes all access control, which compromises device security and is never a recommended practice.
Using insecure protocols such as Telnet exposes credentials in clear text, making remote access vulnerable to interception and attacks.
Authentication controls like TACACS+ and RADIUS provide centralized and stronger authentication management for Cisco network devices.
Changing switch port modes, such as turning access ports into trunk ports, does not affect authentication strength or remote access security.
Effective security decisions focus on enhancing authentication mechanisms rather than simplifying or removing them to maintain device integrity.

Key takeaway
Strong remote administrative access requires authentication methods that go beyond simple username and password combinations to prevent unauthorized access.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
