A. FALSE

B. TRUE

A. 224.0.1.20

B. 224.0.0.20

C. 224.0.1.18

D. 224.0.0.18

A. Stateful inspection firewall

B. Packet filtering firewall

C. Proxy firewall

D. Software firewall

A. Static ACL rules cannot adapt to dynamic security filtering requirements.

B. As the ACL complexity and length increase, the firewall filtering performance deteriorates exponentially.

C. It can fully control network information exchange, and Session control is of high security.

D. It is easy for hackers muddle through without check the session state and analyze the data.

A. FALSE

B. TRUE

A. RSVP is used to transmit signaling of QoS requests, notifying the router of QoS requirements of the application.

B. It can provide a load control service, to ensure that even in the case of network overload, can provide services similar to the network which is not overloaded, that is, in the case of network congestion, this model ensures that packets of some applications can be processed with the low delay.

C. It provides guaranteed bandwidth and delay to meet requirements of the application.

D. In this model, the network maintains the status of each flow (IP addresses and port numbers of source and destination ends), and based on this state packets are classified, policed, queued, and scheduled, meeting application requirements.

A. Dynamic LSPs are established using label distribution protocols, such as MP-BGP, RSVP-TE, and LDP.

B. LSPs are classified into static and dynamic LSPs. A static ISP is manually configured by an administrator. A dynamic ISP is dynamically established using routing and label distribution protocols.

C. When labels are allocated manually, ensure that the outgoing label of an upstream node is the same as the incoming label of the downstream node.

D. LSPs created by static Distribution labels can be dynamically adjusted according to network topology changes, without the need for administrator intervention.

A. FALSE

B. TRUE

A. There is no data packet acknowledgement mechanism.

B. There is no confidentiality guarantee mechanism.

C. There is no data source verification mechanism.

D. There is no data integrity verification mechanism.

A. NAT is automatically switched to PAT, and then subsequent intra net users go online.

B. Packets are synchronized to another NAT translation device.

C. The previous user is disconnected forcibly and subsequent intranet users go online through NAT translation.

D. Subsequent intra net users cannot go online.

A. FALSE

B. TRUE
