Full question →mediummultiple choiceObjective-mapped
A company is setting up a site-to-site VPN between an on-premises network and an Azure virtual network using an Azure VPN gateway. The security policy mandates that the VPN tunnel must use the strongest available encryption and authentication. Which IPsec/IKE parameter combination should they configure on both sides?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
IKEv1 with AES128
IKEv1 is less secure than IKEv2, and AES128 is weaker than AES256.
B
Best answer
IKEv2 with AES256
This combination offers the strongest encryption and key exchange protocol supported by Azure VPN Gateway.
C
Distractor review
IKEv1 with DES
DES is a weak encryption algorithm and IKEv1 is less secure than IKEv2.
D
Distractor review
IKEv2 with 3DES
3DES is considered weak and deprecated; AES is stronger.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-500 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: IKEv2 with AES256 — For the strongest security with Azure VPN Gateway, IKEv2 is recommended over IKEv1. AES256 is a strong symmetric encryption algorithm. For authentication, SHA256 or higher is typical. Among the options, IKEv2 with AES256 is the strongest. DES and 3DES are considered weak and deprecated. IKEv1 should be avoided when possible.
