AZ-800 ExpressRoute Circuit Configuration 5

Question 1

What is the maximum number of IP prefixes that can be advertised from on-premises to Azure over an ExpressRoute private peering connection?

Accepted Answer

4000

Answer

ExpressRoute private peering supports advertising up to 4,000 IP prefixes from on-premises to Azure; exceeding this limit will drop the BGP session.

Question 2

You need to configure ExpressRoute for a connection that uses the provider's MPLS network. The provider uses the same BGP AS number for all customer connections. Which BGP feature must be enabled on the customer router to handle this scenario?

Accepted Answer

BGP Allow-AS-In

Answer

BGP Allow-AS-In must be configured when the provider's MPLS network uses the same AS number, allowing the router to accept routes with its own AS in the path.

Question 3

Which ExpressRoute peering type should be used to access Azure Storage and Azure SQL Database via private IP addresses within a VNet using Private Endpoints?

Accepted Answer

Azure Private Peering

Answer

Azure Private Peering is used to access resources via their private IP addresses, including Private Endpoints for PaaS services like Storage and SQL.

Question 4

When configuring ExpressRoute private peering, which VLAN ID range is valid for the primary and secondary link VLAN tags?

Accepted Answer

1-4094

Answer

VLAN IDs for ExpressRoute primary and secondary links must be in the range 1-4094, and each VLAN ID must be unique across all peerings on the circuit.

Question 5

An organization wants to use a single ExpressRoute circuit to access both Azure private resources and Microsoft 365 services. What must they configure?

Accepted Answer

Private Peering and Microsoft Peering on the same circuit

Answer

A single ExpressRoute circuit can have both Azure Private Peering and Microsoft Peering configured simultaneously to access both types of resources.
