Resumo de Recurso

Questão 1

Questão
Flow-Based Inspection Mode—Full Scan Mode
Responda
  • 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

Questão 2

Questão
Flow-Based Inspection Mode—Full Scan Mode (Select 2)
Responda
  • 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.

Questão 3

Questão
Flow-Based Inspection Mode—Full Scan Mode
Responda
  • 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

Questão 4

Questão
Flow-Based Inspection Mode—Full Scan Mode
Responda
  • 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.

Questão 5

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

Questão 6

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

Questão 7

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

Questão 8

Responda
  • Full scan
  • Quick scan

Questão 9

Questão
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:
Responda
  • 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.

Questão 10

Questão
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
Responda
  • Quick Scan Mode Packet Flow
  • Full Scan Mode Packet Flow

Questão 11

Questão
The quick scan mode option is only available in proxy inspection mode.
Responda
  • True
  • False

Questão 12

Questão
Some entry-level FortiGate models don’t support quick scan flow-based inspection method.
Responda
  • True
  • False

Questão 13

Responda
  • Quick scan
  • Full scan

Questão 14

Questão
?
Responda
  • Proxy inspection mode
  • flow-based inspection mode

Questão 15

Responda
  • Proxy Inspection Mode Packet Flow
  • Flow-based Inspection Mode Packet Flow

Questão 16

Responda
  • Full flow-based Quick flow-based Proxy-based
  • Proxy-based Full flow-based Quick flow-based
  • Quick flow-based Proxy-based Full flow-based

Questão 17

Questão
What two scanning modes are available in flow-based inspection mode? 8.
Responda
  • A. Proxy and NGFW
  • B. Full and quick

Questão 18

Questão
What antivirus database does quick scan mode use?
Responda
  • A. Compact
