  1. Which Azure load balancer SKU supports availability zones and has an SLA guarantee?

    Answer: Standard SKU

    Azure Standard Load Balancer supports availability zones, provides an SLA, and supports both inbound and outbound scenarios across zone-redundant and zonal deployments.

  2. What happens to existing TCP connections when an Azure NAT Gateway public IP is changed?

    Answer: Existing connections are reset (RESET sent)

    Changing the public IP on a NAT Gateway terminates existing SNAT connections because the source IP changes, causing TCP RST to be sent.

  3. In Azure, which address type is assigned from the subnet's address space and persists for the VM's lifetime unless explicitly removed?

    Answer: Static private IP

    A static private IP is manually assigned from the subnet range and remains associated with the network interface until changed by an administrator.

  4. Which networking feature in Azure allows you to access Azure PaaS services over a private endpoint with a private IP address in your VNet?

    Answer: Private Link

    Azure Private Link brings Azure PaaS services into your VNet by assigning them a private IP address through a private endpoint, keeping traffic off the public internet.

  5. A VM in subnet A needs to communicate with a VM in subnet B within the same VNet. An NSG on subnet A denies all outbound traffic. What is the result?

    Answer: Traffic is blocked because NSG outbound rules are evaluated first

    NSG outbound rules on subnet A are evaluated before traffic leaves that subnet; a deny rule blocks the traffic regardless of the destination subnet's NSG settings.

  6. What is the maximum transmission unit (MTU) size for Ethernet frames on Azure virtual networks?

    Answer: 1500 bytes

    Azure virtual networks support standard Ethernet MTU of 1500 bytes; jumbo frames up to 9000 bytes are supported only for specific VM sizes with accelerated networking.

  7. Which BGP attribute is used by Azure ExpressRoute to prefer one path over another when multiple paths exist?

    Answer: AS Path prepending

    AS path prepending is the BGP attribute used to influence inbound route selection in Azure ExpressRoute, making one path appear longer (less preferred) than another.
