• AUpgrading the signature database of Huawei IPS does not require license authorization.

• CUpgrading the signature database of Huawei IPS requires restarting the device to take effect.
• DUpgrade the Huawei IPS signature database to take effect without restarting the device.

• A

• B
  5% (2)
• C
  3% (1)
• D
  81% (30)

Explanation

Option D is correct because Huawei IPS signature database (virus/threat signatures) updates are designed as "hot updates" - they load into memory and activate immediately without requiring a device reboot, ensuring continuous protection with zero downtime.

Why the distractors are wrong:

• A is incorrect: signature database upgrades do require a valid license; Huawei IPS subscriptions gate access to signature updates.
• B is incorrect: system version (firmware/OS) upgrades are the opposite - they do require a restart to take effect, unlike signature updates.
• C is incorrect: this correctly identifies the subject (signature database) but gets the restart requirement backwards - it's the system version that needs a restart, not the signature database.

Memory tip: Think of it as two categories - "Signatures = Soft update, no restart" and "System version = Hard update, needs restart." The signature database is analogous to antivirus definition updates on a PC: they apply live. The system version is like a Windows OS upgrade: reboot required.
