As shown in the figure below, a company uses the USG6600 firewall as the egress. The company has two egresses. Carrier A and carrier B share the egress load. When an engineer deploys the firewall, two egresses are added to the untrust zone at the same time. The user has joined the trust zone and made source NAT mapping. After the deployment, it is found that some users have normal access to the Internet, while some users have very slow access to the Internet, and even sometimes cannot access the Internet.

Based on the above information, please determine which of the following descriptions is correct?

• A. The problem is caused by the user's PC.
• B. It can be inferred that the source NAT configuration is correct.
• C. The issue is related to carrier network stability.
• D. The problem is caused by an equal-cost route.

Which of the following statements is true about the life cycle of an IPsec tunnel:

• A. IPsec SA lifetime can be calculated in traffic.
• B. The lifecycle configuration of both ends must be the same.
• C. The IPsec tunnel will renegotiate a new tunnel when it reaches its lifetime.
• D. The soft timeout is the expiration time of the SA life cycle, and the hard timeout is the time to start negotiating a new SA before the expiration of the life cycle.

The terminal uses Agent for 802.1x authentication, the IP address of SC and Radius server is 172.18.10.68, and it always prompts network communication failure during authentication;
Viewing the Radius authentication log shows that the Radius authentication is successful and the authorization is ACL3001. The switch configuration is as follows:
dot1x enable
dot1x authentication-method eap
radius-server template lzy
radius-server shared-key simple 123456

What could be the reason for the failure of network communication?

• A. Authorization rule ACL configuration error
• B. Billing configuration may be wrong
• C. GigabitEthernet0/0/14 port configuration error

A Web Server deployed in the DMZ area of an enterprise has an intranet IP address of 10.1.1.3 and a port of 8080. The public network address announced to the outside world is 1.1.1.2, and the external port number is 80.
Configure the following commands on the firewall:
[USG6600] security-policy
[[USG6600-policy-security] rule name untrust_to_mz
[USG6600-policy-security-rule-untrust_to_mz] source-zone untrust
[USG6600-policy-security-rule-untrust_to_mz] destination-zone dmz
[USG6600-policy-security-rule-untrust_to_mz] destination-address 1.1.1.2 32
[USG6600-policy-security-rule-untrust_to_mz] service http
[USG6600-policy-security-rule-untrust_to_mz] action permit
[USG6600] nat server webserver protocol tcp global 1.1.1.2 www inside 10.1.1.3 8080
The external network PC cannot access the Web Server of 10.1.1.3 within the enterprise. Please analyze the most likely reasons for this:

• A. Firewall untrust to DMZ zone security policy should be configured as destination-address 10.1.1.3 32
• B. Firewall should be configured as nat server webserver protocol tcp global 1.1.1.2 80 inside 10.1.1.3 8080
• C. Firewall untrust to DMZ zone security policy should be configured as service 8080
• D. The firewall does not open the default packet filtering policy from the untmut zone to the dmz zone

When the NAT address pool is used on the firewall, if the address of the NAT address pool is not in the same network segment as the IP of the outgoing interface of the external network, a route to the address pool needs to be configured on the next-hop router.

• A. FALSE
• B. TRUE
