  A. The authentication-free rule profile is used to permit the IP addresses of anti-virus devices such as the anti-virus gateway and firewall.
  B. The authentication-free rule profile is used to permit the IP addresses of the DNS, DHCP, and authentication servers.
  C. The authentication-free rule profile can use advanced ACLs.
  D. The authentication-free rule profile can permit specified IP addresses only by using ACLs.
  B. The authentication-free rule profile is used to permit the IP addresses of the DNS, DHCP, and authentication servers.

• Question 439:

  What is the correct description about the second Fresnel zone below?

  A. If the RF signal is at the same frequency, out of phase, and the intersection of the main signal, the out-of-phase signal will weaken or even cancel the main signal. Since the reflection is one of the factors that cause the out-of-phase signal to interfere with the main signal, the point-to-point communication chain is evaluated. When considering the road, the influence of the second Fresnel zone on the signal must be considered.
  B. If the signal of the second Fresnel zone is reflected to the receiving end due to antenna height and terrain, the link quality may be reduced.
  C. The impact of the second Fresnel zone should still be taken into account when planning the network or troubleshooting, especially in flat, arid environments such as deserts.
  D. The first Fresnel zone surrounds the second Fresnel zone.
