質問 # 30
Which two statements about user-defined security zones are correct? (Choose two.)

  • A. Users can configure multiple security zones.
  • B. Users cannot share security zones between routing instances.
  • C. User-defined security zones do not apply to transit traffic.
  • D. Users can share security zones between routing instances.

正解：A、D

解説：
User-defined security zones allow users to configure multiple security zones and share them between routing instances. This allows users to easily manage multiple security zones and their associated policies. For example, a user can create a security zone for corporate traffic, a security zone for guest traffic, and a security zone for public traffic, and then configure policies to control the flow of traffic between each of these security zones. Transit traffic can also be managed using user-defined security zones, as the policies applied to these zones will be applied to the transit traffic as well.

質問 # 34
What is the default value of the dead peer detection (DPD) interval for an IPsec VPN tunnel?

  • A. 10 seconds
  • B. 40 seconds
  • C. 20 seconds
  • D. 5 seconds

正解：D

解説：
The default value of the dead peer detection (DPD) interval for an IPsec VPN tunnel is 5 seconds. DPD is a mechanism that enables the IPsec device to detect if the peer is still reachable or if the IPsec VPN tunnel is still active. The DPD interval determines how often the IPsec device sends DPD packets to the peer to check the status of the VPN tunnel. A value of 5 seconds is a common default, but the specific value can vary depending on the IPsec device and its configuration.

質問 # 41
You are asked to configure your SRX Series device to block all traffic from certain countries. The solution must be automatically updated as IP prefixes become allocated to those certain countries.
Which Juniper ATP solution will accomplish this task?

  • A. Geo IP
  • B. IDP
  • C. unified security policies
  • D. C&C feed

正解：A

解説：
Juniper ATP Geo IP can help to accomplish this task by using geolocation services to determine the geographical location of IP addresses. As IP prefixes get allocated to the countries that you have specified, the Geo IP solution will automatically update the configured firewall policies to block any traffic that is coming from those specific countries.
This is a great solution for blocking specific countries - as it will allow for a more personalized and targeted approach to firewall policies - and thus, to increase the effectiveness of the solution at blocking potential malicious traffic.
