Question 311 of 1,000
Secure networkinghardMultiple SelectObjective-mapped

Quick Answer

The answer is to configure VNet peering between the virtual networks and ensure you enable encrypted cross-region VNet peering. This is correct because Global VNet Peering connects virtual networks across Azure regions using the Microsoft backbone network, keeping all traffic within Azure’s secure infrastructure and avoiding the public internet. Encryption for VNet peering is now supported, ensuring data confidentiality while minimizing latency by using the high-speed backbone rather than a VPN gateway or ExpressRoute. On the AZ-500 exam, this question tests your understanding of network security controls and connectivity options—a common trap is assuming you need a VPN gateway for encryption, but VNet peering natively supports it. Remember the memory tip: “Peering is private, VPN is public; for backbone speed, peering is the lead.”

AZ-500 Secure networking Practice Question

This AZ-500 practice question tests your understanding of secure networking. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

You are designing a secure network architecture for a multi-region application. You need to ensure that traffic between virtual networks in different Azure regions is encrypted and uses the Microsoft backbone network, and you must minimize latency. Which TWO configurations should you implement?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "minimum / minimize"

    Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.

Answer choices

Why each option matters

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

Correct answer & explanation

Configure VNet peering between the virtual networks.

Options A and B are correct. VNet peering uses Microsoft backbone and supports encryption. Global VNet peering connects across regions. Azure VPN Gateway would route over the internet, and ExpressRoute is an alternative but not required. Azure Firewall is for inspection, not connectivity.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Enable 'Gateway transit' on the peering to use a VPN gateway if needed, but not required for encryption.

    Why it's wrong here

    Gateway transit is for using a shared VPN gateway, but VNet peering itself can encrypt traffic when 'Configure traffic encryption' is enabled.

  • Configure VNet peering between the virtual networks.

    Why this is correct

    VNet peering connects VNets using the Microsoft backbone and can be enabled globally.

    Clue confirmation

    The clue word "minimum / minimize" in the question point toward this answer.

    Related concept

    Static NAT maps one inside address to one outside address.

  • Use Azure ExpressRoute with Microsoft peering.

    Why it's wrong here

    ExpressRoute provides dedicated private connectivity but is more expensive and not necessary if VNet peering suffices.

  • Deploy Azure VPN Gateway in each region and connect them via site-to-site VPN.

    Why it's wrong here

    VPN Gateway routes over the internet, not over the Microsoft backbone, and adds latency.

  • Place an Azure Firewall in each region to inspect cross-region traffic.

    Why it's wrong here

    Firewall is for inspection, not for connectivity or encryption.

Common exam traps

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.

Detailed technical explanation

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.

Key takeaway

NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Real-world example

How this comes up in practice

A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.

What to study next

Got this wrong? Here's your next step.

Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related AZ-500 NAT questions on configuration and troubleshooting.
