IT マネージャーは、メッシュ ネットワークで 10 個のサイトを接続する必要があります。各サイトは、プロビジョニング時間を短縮して保護する必要があります。次のテクノロジのうち、この要件を最もよく満たすものはどれですか。
正解:A
* Definition of SD-WAN: * Software-Defined Wide Area Network (SD-WAN) is a technology that simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. It allows for centralized management and enhanced security. * Benefits of SD-WAN: * Reduced Provisioning Time: SD-WAN enables quick and easy deployment of new sites with centralized control and automation. * Security: Incorporates advanced security features such as encryption, secure tunneling, and integrated firewalls. * Scalability: Easily scales to accommodate additional sites and bandwidth requirements. * Comparison with Other Technologies: * VXLAN (Virtual Extensible LAN): Primarily used for network virtualization within data centers. * VPN (Virtual Private Network): Provides secure connections but does not offer the centralized management and provisioning efficiency of SD-WAN. * NFV (Network Functions Virtualization): Virtualizes network services but does not specifically address WAN management and provisioning. * Implementation: * SD-WAN solutions are implemented by deploying edge devices at each site and connecting them to a central controller. This allows for dynamic routing, traffic management, and security policy enforcement. References: * CompTIA Network+ course materials and networking solution guides.
