What interface type must the administrator select to bind multiple FortiGate interfaces?

An administrator needs to increase network bandwidth and provide redundancy.

What interface type must the administrator select to bind multiple FortiGate interfaces?
A . VLAN interface
B . Software Switch interface
C . Aggregate interface
D . Redundant interface

Answer: C

Explanation:

Link aggregation (IEEE 802.3ad) enables you to bind two or more physical interfaces together to form an aggregated (combined) link. This new link has the bandwidth of all the links combined. If a link in the group fails, traffic is transferred automatically to the remaining interfaces with the only noticeable effect being a reduced bandwidth.

To increase network bandwidth and provide redundancy, an administrator can use an Aggregate Interface (also known as Link Aggregation or Port Channel). This interface type allows multiple physical interfaces to be combined into a single logical interface, providing increased bandwidth and fault tolerance. This logical interface appears as a single interface to the rest of the network, and it distributes traffic across the member interfaces.
