The correct answer is implementing multi-factor authentication (MFA) for remote access VPN users and restricting split-tunneling to only trusted networks and applications. MFA, such as requiring a one-time password via RADIUS servers like Cisco ISE or Duo, enforces defense-in-depth by adding a second authentication factor beyond a simple password, drastically reducing the risk of credential theft. Split-tunneling, when used without restriction, can expose the corporate network to threats from the user’s local internet connection, so limiting it to trusted destinations ensures that sensitive traffic remains encrypted through the VPN tunnel. On the Cisco SCOR 350-701 exam, this pair of best practices tests your understanding of secure remote access design, often appearing in a “choose two” format where one distractor suggests disabling split-tunneling entirely or using only pre-shared keys. A common trap is assuming MFA alone is sufficient, but the exam emphasizes that split-tunneling must be explicitly controlled, not just enabled. Remember the mnemonic “MFA for the door, split for the floor”—authenticate every user, but only route trusted traffic through the tunnel.
350-701 Network Security Practice Question
This 350-701 practice question tests your understanding of network security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which TWO are best practices for securing Cisco ASA remote access VPN? (Choose two.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enforce multi-factor authentication (MFA) for VPN users.
Option C is correct because enforcing multi-factor authentication (MFA) for VPN users adds an additional layer of security beyond just a password, significantly reducing the risk of credential theft and unauthorized access. Cisco ASA supports MFA integration with RADIUS servers (e.g., Cisco ISE, Duo Security) that can require a one-time password (OTP) or push notification, aligning with the principle of defense-in-depth for remote access VPNs.
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.
✗
Disable clientless SSL VPN to force full-tunnel client.
Why it's wrong here
Clientless SSLVPN can be useful; disabling not a best practice.
✗
Use pre-shared keys for user authentication to simplify deployments.
Why it's wrong here
PSKs are not user-specific and weak for remote access.
✓
Enforce multi-factor authentication (MFA) for VPN users.
The clue word "best" in the question point toward this answer.

✗
Use L2TP/IPsec for legacy compatibility.
Why it's wrong here
Not recommended; use SSLVPN or IKEv2 for modern ASA.
✓
Implement split-tunneling only for trusted networks and applications.
Why this is correct
Split-tunneling reduces traffic to VPN but must be limited to avoid security risks.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that disabling clientless SSLVPN or using pre-shared keys simplifies security, when in fact these options either do not enforce full-tunnel behavior or introduce significant authentication weaknesses.
Detailed technical explanation
How to think about this question
Multi-factor authentication for Cisco ASA VPNs typically leverages RADIUS with a token server (e.g., RSA SecurID, Duo) that sends a challenge-response or push notification. The ASA acts as a RADIUS client, and the user must provide both a primary credential (e.g., AD password) and a secondary factor (e.g., OTP) before the tunnel is established. In a real-world scenario, if an attacker steals a user's password, MFA blocks access because the second factor is not compromised, which is critical for compliance with frameworks like PCI DSS or NIST.

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
