Question 8

A company is designing a hub-spoke network topology in Azure. The hub contains a third-party network virtual appliance (NVA) for inspection. Spokes need to communicate with each other, and all inter-spoke traffic must be routed through the NVA in the hub. Which configuration should they use?

Accepted Answer

Create user-defined routes (UDRs) in each spoke subnet that force traffic to go through the hub NVA. User-defined routes (UDRs) allow you to explicitly override Azure's default system routes. By adding a route in each spoke subnet with the hub NVA's private IP as the next hop for inter-spoke traffic (e.g., 10.1.0.0/16 -> 10.0.0.4), all traffic between spokes is forced through the NVA for inspection. This ensures the hub-spoke topology meets the requirement without relying on Azure Firewall or Internet routing.

Set route tables on spoke subnets with a 0.0.0.0/0 route to the Internet

Answer

Configure Azure Firewall in the hub with forced tunneling to on-premises

Answer

Use VNet peering with gateway transit enabled

Question 9

A company runs a critical SQL Server database on Azure Virtual Machines in a single region. They need a disaster recovery solution across regions with a recovery point objective (RPO) of zero. The database is update-intensive with frequent writes. Which configuration should they implement?

Accepted Answer

SQL Server Always On Availability Group with synchronous commit across regions.. SQL Server Always On Availability Group with synchronous commit across regions ensures zero data loss because transactions are committed on both the primary and secondary replicas before the primary acknowledges the commit. This meets the RPO of zero, even though it introduces latency due to cross-region synchronization. For an update-intensive workload, synchronous commit is the only option that guarantees no data loss at the cost of increased write latency.
