AZ-700 Networking Fundamentals 5

Question 1

You need to capture and analyze network traffic flowing through a VM's NIC in Azure. Which tool provides this capability natively?

Accepted Answer

Azure Network Watcher packet capture

Answer

Azure Network Watcher's packet capture feature allows you to remotely capture network traffic to/from a VM's NIC for troubleshooting and analysis.

Question 2

What is the primary difference between Azure VNet peering and Azure VPN Gateway for connecting two VNets?

Accepted Answer

VNet peering uses the Microsoft backbone with low latency; VPN uses encrypted tunnels with higher latency

Answer

VNet peering uses the Azure backbone for low-latency, high-bandwidth private connectivity, while VPN Gateway establishes encrypted IPsec tunnels with higher latency.

Question 3

Which Azure service enables you to centrally manage routing across multiple VNets using a hub-and-spoke topology as a managed service?

Accepted Answer

Azure Virtual WAN

Answer

Azure Virtual WAN provides a managed hub-and-spoke networking service that automates branch connectivity, routing, and security across multiple VNets and sites.

Question 4

An NSG rule has priority 100 and allows port 80 inbound. Another rule has priority 200 and denies all inbound traffic. What is the result for HTTP traffic?

Accepted Answer

Traffic is allowed because the lower priority number (100) is evaluated first

Answer

NSG rules are evaluated in order from lowest priority number to highest; the allow rule at priority 100 is matched first, so HTTP traffic is permitted.

Question 5

What mechanism does Azure use to prevent IP spoofing on virtual machine network interfaces?

Accepted Answer

IP forwarding disabled by default

Answer

Azure blocks IP spoofing by default because IP forwarding is disabled on NICs; any packet with a source IP not matching the NIC's assigned IP is dropped by the hypervisor.
