Huawei HCIE-Security (Huawei Certified Internetwork Expert-Security) Sample Questions:
1. As shown in the figure, the corresponding defense methods are:
A) Payload Check Defense
B) Authenticate the user through the associated TCP protocol
C) Defense by TTL checking
D) Fingerprint Learning Defense
E) Method defense through source authentication
2. A server on the network has been responding very slowly recently. By looking at its running status, it is found that its CPU and memory usage ratio is high, but there is little or no data transmission in these TCP session connections.
For the following judgments about this problem phenomenon, please choose the best one:
A) The server is under HTTP POST slow attack.
B) The server is under a TCP spoofing attack.
C) The server is under SYN flood attack.
D) The server is under UDP flood attack.
3. The correct description of the no-reverse parameter in the firewall NAT Server configuration command is:
A) Configure nat server without the no-reverse parameter. When a public network user accesses the server, the firewall can convert the server's public network address into a private network address; when the server actively accesses the public network, the firewall can also convert the server's public network address. The private network address is converted into a public network address.
B) Configure the nat server with the parameter no-reverse. When the public network user accesses the server, the firewall can convert the server's public network address into a private network address; when the server actively accesses the public network, the firewall can also convert the server's public network address. Convert the private network address to the public network address.
C) Configure the nat server without the no-reverse parameter, the device only converts the public network address to the private network address, and cannot convert the private network address to the public network address.
D) Configure the nat server with the parameter no-reverse, the device only converts the public network address to the private network address, and cannot convert the private network address to the public network address.
4. SYN Flood attacks can be prevented through TCP reverse source detection and TCP proxy technology. Comparing the two defense technologies, the correct statement is:
A) The use of TCP proxy mode can be used in scenarios where the round-trip paths are inconsistent.
B) When the SYN packet rate reaches the alarm value alert-rate-number, the device can perform source authentication check on SYN packets.
C) The defense technology of reverse source detection mechanism and TCP proxy mode must enable state detection mechanism.
D) Only when the rate of SYN packets reaches the alarm value alert-rate-number, the device can check the SYN packets by the TCP proxy.
5. A network uses Agile Controller for 802.1X authentication, in which the S switch GigabitEthernet 0/0/9 is connected to the terminal host and the printer, the printer passes MAC authentication, and the terminal host needs to pass the Agent to pass the authentication. What is the correct configuration of the switch?
A) [Quidway] dot1x enable [Quidway] dot1X authentication-method eap [Quidway] interface GigabitEthernet 0/0/9 [Quidway-GigabitEthernet 0/0/9] port link-type trunk
B) [Quidway] dotlx enable [Quidway] dot1X authentication-method eap [Quidway] interface GigabitEthernet 0/0/9 [Quidway-GigabitEthernet 0/0/9] port link-type a [Quidway-GigabitEthernet 0/0/ 9] port default vlan 105 [Quidway-GigabitEthernet 0/0/9] dot1x enable [Quidway-GigabitEthernet 0/0/9] dot1x port-method MAC
C) [Quidway] dot1X authentication-method eap [Quidway] interface GigabitEthernet 0/0/9 [Quidway-GigabitEthernet 0/0/9] port link-type a [Quidway-GigabitEthernet 0/0/9] port default vlan 105 [Quidway-GigabitEthernet 0/0/9] dot1x port-method MAC
