Pregunta 1

Pregunta
Flow-Based Inspection Mode—Full Scan Mode
Respuesta
  • Uses the full antivirus database : Normal, extended, or extreme—depending on what is configured in the CLI
  • Uses the normal antivirus database : Normal, extended, or extreme—depending on what is configured in the CLI

Pregunta 2

Pregunta
Flow-Based Inspection Mode—Full Scan Mode (Select 2)
Respuesta
  • Optimized performance compare to proxy-based scan
  • Optimized performance compare to flow-based scan
  • 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.

Pregunta 3

Pregunta
Flow-Based Inspection Mode—Full Scan Mode
Respuesta
  • 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

Pregunta 4

Pregunta
Flow-Based Inspection Mode—Full Scan Mode
Respuesta
  • 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.

Pregunta 5

Pregunta
When the antivirus profile is operating in proxy inspection mode, two scanning mode options are available
Respuesta
  • True
  • False

Pregunta 6

Pregunta
When the antivirus profile is operating in flow-based inspection mode, two scanning mode options are available:
Respuesta
  • full scan mode quick scan mode
  • full scan mode medium scan mode

Pregunta 7

Pregunta
Because the file is transmitted simultaneously, flow inspection mode scanning consumes more CPU cycles.
Respuesta
  • True
  • False

Pregunta 8

Respuesta
  • Full scan
  • Quick scan

Pregunta 9

Pregunta
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:
Respuesta
  • then flow inspection mode is more appropriate. If security is your priority, proxy inspection mode—with client comforting disabled—is more appropriate.
  • then proxy inspection mode is more appropriate. If security is your priority, flow inspection mode—with client comforting disabled—is more appropriate.

Pregunta 10

Pregunta
Uses 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
Respuesta
