The network administrator of a company discards traffic that exceeds the throughput of the device. The USG discards the traffic that exceeds the device throughput. The USG discards the traffic that exceeds the device throughput. The following command can achieve this function?
The dual-system hot backup load balancing service interface works at Layer 3, and the upstream and downstream routers are connected to each other. The two USG devices are active and standby. Therefore, both the hrp track master and the hrp track slave must be configured on the morning service interface.
Note: When dual-system hot backup load sharing is configured, the upstream and downstream routers are configured with equal-cost routes, and no HRP OSPF cost is required. When the dual-system hot standby network is deployed, the standby firewall automatically adds a COST value when it routes routes to the outside (the default is 65500).
On the following virtual firewall network, the USG unified security gateway provides leased services to the enterprise. The VPN instance vfw1 is leased to enterprise
key configuration: First, create/delete VPN instance [undo] ip vpn-instance vpn-instance-name [vpn-id vpn-id] Second, specify the route ID for the VPN instance route-distinguisher vpn-route-distinguisher
Avoid DHCP server spoofing attacks. DHCP snooping is usually enabled. What is the correct statement?
Note: DHCP snooping is a DHCP security feature that filters DHCP messages that do not contain information through MAC address restriction, DHCP snooping security binding, IP+MAC binding, and Option 82 features. DHCP DoS attack, DHCP server spoofing attack, ARP man-in-the-middle attack, and IP/MAC Snooping attack. DHCP snooping is enabled on all interfaces of the DHCP client. If the user-side interface is not configured with the Trusted mode, the interface is enabled with the Snooping feature. The default interface mode is Untrusted. This prevents the DHCP server from being attacked by the bogus. To prevent the attack from being attacked by the DHCP server, you can configure the DHCP snooping function on the device to configure the interface on the user side as Untrusted and the interface on the DHCP server as Trusted. All received from the Untrusted interface. DHCP relay packets are discarded. DHCP snooping is configured on the firewall. The DHCP snooping binding function is used to forward packets only if the received packets are the same as those in the binding table. Otherwise, the packets are discarded.
When configuring the USG hot standby, (assuming the backup group number is 1), the configuration command of the virtual address is correct?
