  1. 1Flow-Based Inspection Mode—Full Scan Mode
    1. AUses the full antivirus database :
      Normal, extended, or extreme—depending on what is configured in the CLI
    2. BUses the normal antivirus database :
      Normal, extended, or extreme—depending on what is configured in the CLI
  2. 2Flow-Based Inspection Mode—Full Scan Mode (Select 2)

    1. AOptimized performance compare to proxy-based scan
    2. BOptimized performance compare to flow-based scan
    3. CFortiGate buffers the whole file, but transmits to the client simultaneously.
    4. DFortiGate buffers only a part of the file, and not transmits to the client simultaneously.
  3. 3Flow-Based Inspection Mode—Full Scan Mode

    1. AWhen 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
    2. BWhen 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
  4. 4Flow-Based Inspection Mode—Full Scan Mode

    1. AIf 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.
    2. BIf 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.
  5. 5When the antivirus profile is operating in proxy inspection mode, two scanning mode options are available
    1. AVerdadero
    2. BFalso
  6. 6When the antivirus profile is operating in flow-based inspection mode, two scanning mode options are available:
    1. Afull scan mode
      quick scan mode
    2. Bfull scan mode
      medium scan mode
  7. 7Because the file is transmitted simultaneously, flow inspection mode scanning consumes more CPU cycles.
    1. ATrue
    2. BFalse
  8. 8?Imagen de la pregunta 8
    1. AFull scan
    2. BQuick scan
  9. 9Regardless 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:
    1. Athen flow inspection mode is more appropriate. If security is your priority, proxy inspection mode—with client comforting disabled—is more appropriate.
    2. Bthen proxy inspection mode is more appropriate. If security is your priority, flow inspection mode—with client comforting disabled—is more appropriate.
  10. 10Uses the IPS engine and embedded compact antivirus database
    Faster, less memory usage because the file is not cached, but lower catching rate
    Cannot send files to FortiSandbox for inspection
    Cannot use advanced heuristics and mobile malware package
    1. AQuick Scan Mode Packet Flow
    2. BFull Scan Mode Packet Flow
