The Fortinet Security Fabric is an architectural approach designed to integrate disparate security devices into a single, cohesive entity. Its primary benefit is providing broad visibility, integrated threat intelligence, and automated response across the entire attack surface. A core component of this architecture is centralized management, which allows administrators to configure, monitor, and manage multiple Fortinet products (such as FortiGate, FortiSwitch, and FortiAP) from a single pane of glass, typically the root FortiGate or FortiManager. This simplifies administration, ensures consistent policy enforcement, and reduces operational complexity.

B. It increases the speed of IPsec VPN tunnels: The Security Fabric is an integration framework; it does not inherently increase the cryptographic throughput of IPsec VPNs, which is dependent on the FortiGate's hardware (ASICs) and software.

C. It reduces the need for firewall policies: The Security Fabric does not eliminate the need for firewall policies. Instead, it enhances policy management by enabling consistent and dynamic policy application across multiple integrated devices.

D. It automatically configures VLANs on FortiSwitches: While FortiLink (a key feature of the Security Fabric) does automate VLAN configuration on FortiSwitches, this is a specific feature, not the overarching benefit. Centralized management is the broader concept that encompasses this capability.

Page 3: "The Fortinet Security Fabric is an architectural approach that allows Fortinet and Fabric-Ready partner devices to be managed as a single system." This statement directly supports the concept of centralized management as a core function.

giving you a single pane of glass to manage your network." This explicitly confirms that a primary benefit is unified management.
