Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Which connection method is often considered to have the most secure and reliable performance?

1. Point-to-Site VPN

2. Site-to-Site VPN

3. Azure ExpressRoute

4. Public VPN Gateway

The correct answer is: Azure ExpressRoute

Azure ExpressRoute is recognized for providing the most secure and reliable performance among the connection methods mentioned. This is primarily because ExpressRoute establishes a private connection between Azure and your on-premises network, bypassing the public internet. This private connection greatly reduces the potential security risks associated with sending data over the internet. Moreover, ExpressRoute connections typically result in more consistent latencies and higher throughput than traditional VPN connections, which are contingent on internet traffic conditions. This makes ExpressRoute particularly valuable for organizations that need a direct, resilient connection for critical applications and data transfers. In comparison, other connection methods like Point-to-Site VPN and Site-to-Site VPN are reliant on public internet infrastructure, making them more susceptible to fluctuations in performance and security vulnerabilities. Public VPN Gateways, while they offer encrypted communication over the internet, share similar concerns regarding reliability and security due to dependence on an external network.
