Question 1,270 of 2,015

VPN Technologies →mediumMatchingObjective-mapped

Quick Answer

The answer is Site-to-Site IPsec VPN: IKEv1 or IKEv2 with ESP. This pairing is correct because a traditional site-to-site VPN establishes a secure tunnel between two fixed gateways using the Internet Key Exchange protocol to negotiate security associations, with Encapsulating Security Payload providing both confidentiality and integrity for the data traversing the tunnel. On the ENCOR 350-401 exam, this drag-and-drop task tests your ability to distinguish between Cisco’s VPN architectures: DMVPN relies on mGRE and NHRP for dynamic spoke-to-spoke tunnels, FlexVPN is IKEv2-only, GET VPN uses GDOI for group encryption, and AnyConnect uses TLS/DTLS for client-based remote access. A common trap is confusing FlexVPN’s IKEv2 requirement with the broader IKEv1 or IKEv2 support of a standard site-to-site IPsec VPN. Memory tip: think “Static Site = IKEv1 or v2,” while “Flex = only v2,” and “DM = dynamic mGRE.”

350-401 VPN Technologies Practice Question

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

DMVPN: mGRE with NHRP

DMVPN uses mGRE and NHRP; FlexVPN uses IKEv2; GET VPN uses GDOI; AnyConnect uses TLS/DTLS; Site-to-Site IPsec VPN uses IKEv1 or IKEv2 with ESP.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

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 350-401 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.

What to study next

Got this wrong? Here's your next step.

Identify which 350-401 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
