質問 # 162
An enterprise purchased private lines from two operators. In order to optimize the lines, the enterprise used BGP to learn routing entries from the two operators. However, the enterprise found that the traffic of the egress route increased greatly after this configuration. After the network engineering investigation, it was found that the traffic of the two operators was passed to each other through the enterprise egress router.
Therefore, the enterprise intends to use the routing strategy so that the traffic of the packets of different carriers is no longer passed to each other. Is the configuration in the following figure correct?
- A. TRUE
- B. FALSE
正解：A
質問 # 163
Which statement is correct about this configuration? (Multiple choice)
[Quidway]dhcp enable[Quidway]interface vlanif 10[Quidway-Vlanif10]ip addres 10.1.1.1255.255255.128[Quidway-Vlanif10]dhcp select gloal[Quidway-Vlanif10]quit[Quidway]dhcp server ping packets 10
- A. This command is to configure the clients under the VLANIF10 interface to obtain IP addresses from the global support
- B. The interface address pool has priority over the global address allocation. That is, if there is an interface address pool on the interface, even if the global address pool also exists, the client will give priority to obtaining addresses from the interface address pool.
- C. The maximum number of ping packets sent by the DHCP server is 10
- D. This command is used to configure and enable DHCP service
- E. The maximum number of ping packets received by the DHCP server is 10
正解：A、B、C、D
質問 # 164
The session-based stateful inspection firewall has different processing flows for the first packet and subsequent packets. Which of the descriptions of the flow is correct? (Multiple choice)
- A. When the state check mechanism is turned on, subsequent packets also need to be checked for security policies.
- B. When a packet arrives at the firewall, it will look up the session table. If there is no match, the firewall will process the first packet.
- C. When the packet reaches the firewall, it will look up the session table, and if it matches the firewall, the subsequent packet processing process will be performed.
- D. When the stateful inspection mechanism is enabled, when the firewall processes TCP packets, only SYN packets can establish a session.
正解：B、C、D
