FortiGate buffers the whole file, but transmits to the client simultaneously.
FortiGate buffers only a part of the file, and not transmits to the client simultaneously.
Question 3
Question
Flow-Based Inspection Mode—Full Scan Mode
Answer
When the last packet arrives, the AV engine starts the scan.
Files bigger than buffer size are not scanned—can enable logging of these files.
Packets are not delayed by scan—exceptlastpacket.
Lower perceived latency-data loads faster
When the first packet arrives, the AV engine starts the scan.
Files bigger than buffer size are scanned— can´t enable logging of these files.
Packets are not delayed by scan—except first packet.
Faster perceived latency-data loads lower
Question 4
Question
Flow-Based Inspection Mode—Full Scan Mode
Answer
If a virus is detected, the last packet is dropped and the connection is reset. If an identical request is made, the block replacement page is inserted immediately.
If a virus is detected, the first packet is dropped and the connection is reset. If an identical request is made, the block replacement page is inserted again.

Question 6
Question
When the antivirus profile is operating in flow-based inspection mode, two scanning mode options are available:
Answer
full scan mode
quick scan mode
full scan mode
medium scan mode
Question 7
Question
Because the file is transmitted simultaneously, flow inspection mode scanning consumes more CPU cycles.
Regardless of which mode you use, the scan techniques give similar detection rates. How can you choose between the scan engines? If performance is your top priority:
Answer
then flow inspection mode is more appropriate. If security is your priority, proxy inspection mode—with client comforting disabled—is more appropriate.
