A global financial institution is migrating its on-premises data centers to a hybrid cloud environment, leveraging Azure. A critical requirement for their Zero Trust strategy is to ensure that all network communication between their on-premises network, Azure Virtual Networks, and other cloud providers is encrypted and inspected for threats, without relying solely on traditional perimeter firewalls. Which architectural component is essential for establishing secure, inspected network pathways across these diverse environments?
- AAzure Load Balancer
- BAzure DNS
- CAzure CDN
- DSD-WAN Integration
Show answer & explanationAnswer & explanation
Correct answer: D. SD-WAN Integration
SD-WAN (Software-Defined Wide Area Network) integration allows for the creation of secure, optimized, and centrally managed network connections across diverse environments, including on-premises, Azure, and other cloud providers. It enables encrypted tunnels and can integrate with security services for threat inspection, fulfilling the requirement for secure, inspected pathways beyond traditional firewalls.
Why the other options are wrong
- A. Azure Load Balancer distributes incoming network traffic across multiple backend resources and does not provide comprehensive hybrid cloud network security or threat inspection across diverse environments.
- B. Azure DNS provides domain name resolution and is not involved in establishing secure network pathways or threat inspection.
- C. Azure CDN (Content Delivery Network) is used for content delivery and caching, not for securing hybrid cloud network connections.
SD-WAN Integration (Zero Trust)
Integrating Software-Defined Wide Area Network (SD-WAN) solutions into a Zero Trust architecture provides secure, optimized, and centrally managed network connectivity across hybrid and multi-cloud environments. It enables dynamic routing, encryption, and often integrates with security services for threat inspection at the network edge, extending Zero Trust principles to the network fabric.
- Secure, optimized hybrid/multi-cloud connectivity
- Centralized network management
- Enables dynamic routing and encryption
- Integrates with security services for inspection
Memory trick: SD-WAN weaves a secure fabric across all your locations.
