Question 1

Which Azure service provides a fully managed, cloud-based network address translation (NAT) gateway to allow outbound internet connectivity from a virtual network?

Accepted Answer

Azure NAT Gateway

Answer

Azure NAT Gateway provides outbound-only internet connectivity for resources in a virtual network without exposing inbound internet access.

Question 2

What is the default behavior when two Azure Virtual Networks are NOT peered together?

Accepted Answer

They are completely isolated and cannot communicate

Answer

Virtual networks in Azure are logically isolated from each other by default; communication requires explicit configuration such as VNet peering or VPN.

Question 3

Which IP address range is NOT a valid private IP address range per RFC 1918?

Accepted Answer

198.51.100.0/24

Answer

198.51.100.0/24 (TEST-NET-2) is reserved for documentation purposes, not private use; the RFC 1918 ranges are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.

Question 4

In Azure, what is the minimum subnet size allowed when creating a subnet in a virtual network?

Accepted Answer

/29 (8 addresses)

Answer

Azure requires a minimum subnet prefix of /29, which provides 8 IP addresses (3 usable after reserving 5 for Azure infrastructure).

Question 5

Which OSI layer does the Azure Application Gateway primarily operate at?

Accepted Answer

Layer 7 (Application)

Answer

Azure Application Gateway is a Layer 7 load balancer that can make routing decisions based on HTTP attributes such as URI path or host headers.
