Quick Answer
The correct statement is that the IKEv1 SA is established with the peer 10.1.1.2. This is confirmed by the "ACTIVE" status in the output of the show crypto isakmp sa detail command, which indicates a successfully negotiated Phase 1 tunnel, while the "C-id" and "C" code explicitly denote IKEv1 rather than IKEv2. On the Cisco CCNP ENARSI 300-410 exam, this command tests your ability to verify IKEv1 security associations, focusing on the critical fields: status, encryption (AES), hash (SHA), authentication (psk), and Diffie-Hellman group (14). A common trap is confusing the "ACTIVE" status with a fully established IPsec tunnel—remember that this output only confirms the ISAKMP (IKE) Phase 1 SA, not the IPsec Phase 2 SA. The lifetime of 23:59:59 shows the SA will renegotiate in about 24 hours, and the absence of an I-VRF means no VRF is used. Memory tip: "C-id" stands for "Crypto IKEv1 ID," so if you see a "C" code, you know it's IKEv1, not IKEv2.
This 300-410 practice question tests your understanding of ipsec site-to-site vpn. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
A network engineer runs the following command on Router R1:
R1# show crypto isakmp sa detail
Codes: C - IKEv1, I - IKEv2
C-id Local Remote I-VRF Status Encr Hash Auth DH Lifetime Cap 1 10.1.1.1 10.1.1.2 ACTIVE aes sha psk 14 23:59:59
Based on this output, which statement is correct?
The IKEv1 SA is established with the peer 10.1.1.2.
The 'C' code indicates IKEv1, and the status is ACTIVE.
The IKEv2 SA is established with the peer 10.1.1.2.
Why wrong: The code 'C' indicates IKEv1, not IKEv2.
The ISAKMP SA is not established; status is MM_NO_STATE.
Why wrong: Status is ACTIVE, meaning it is established.
The Diffie-Hellman group is group 2.
Why wrong: The DH group is 14.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The IKEv1 SA is established with the peer 10.1.1.2.
The ISAKMP SA is active, using AES encryption, SHA hash, pre-shared key authentication, and Diffie-Hellman group 14. The lifetime is about 24 hours.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
The IKEv1 SA is established with the peer 10.1.1.2.
Why this is correct
The 'C' code indicates IKEv1, and the status is ACTIVE.
Related concept
Read the scenario before looking for a memorised answer.
The IKEv2 SA is established with the peer 10.1.1.2.
Why it's wrong here
The code 'C' indicates IKEv1, not IKEv2.
The ISAKMP SA is not established; status is MM_NO_STATE.
Why it's wrong here
Status is ACTIVE, meaning it is established.
The Diffie-Hellman group is group 2.
Why it's wrong here
The DH group is 14.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 300-410 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.
