NEW QUESTION 242
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)

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.

NEW QUESTION 248
ASPF (Application Specific Packet Filter) is a packet filter based on the application layer.

ASPF monitors messages during communication

ASPF dynamically creates and deletes filtering rules

ASPF dynamically allows multi-channel protocol data to pass through the Servermap table

The five-tuple Server-map entry implements a similar function to the session table

NEW QUESTION 249

Please match the following check items to the corresponding levels according to the hierarchical method.

NEW QUESTION 256
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?

TRUE

FALSE

In MPLS VPNE, in order to distinguish IPV4 prefixes that use the same address space, the IPV4 address is increased by the RD value. Which of the following description is correct? (Multiple choice)

On a PE device, each VPN instance corresponds to an RD value. On the same PE device, the RD value must be unique.

RD can be used to control the publication of VPN routing information

RD is encapsulated in the Update message as an extended community of BGP during the delivery process

After the PE receives the IPv4 route from the CE, it adds RD to the IPv4 route to convert it into a globally unique VPN-IPv4 route, and publishes it on the public network
