Complex traffic classification means that packets are classified based on the quintuple including the source and destination addresses, source and destination port numbers, and protocol type. It is usually deployed on the network core.

A. TRUE

B. FALSE

Which of the following statements regarding VRRP load balancing are true? (Multiple Choice)

A. Multiple virtual routers can be configured on an interface of a router so that the router functions as the master of the virtual router and the backup of another virtual router.

B. In load balancing mode, multiple routers transmit service at the same time, so at least two or more virtual routers are required.

C. In load balancing mode, two or more VRRP groups are created, and multiple routers transmit services.

D. During priority configuration, the VRRP master of the three virtual routers can be on different routers.

NAT technology can only translate network layer information (IP address) in data packets.

A. TRUE

B. FALSE

NAT technology implements data security transmission through data encryption.

A. TRUE

B. FALSE

DHCP snooping can prevent bogus DHCP server attacks. Which of the following are the required configuration steps? (Multiple Choice)

A. Enable DHCP globally.

B. Enable DAI Snooping globally.

C. Enable DHCP snooping on an interface or VLAN.

D. Configure an interface as a trusted or untrusted interface.

LDP uses different neighbor discovery mechanisms. Which of the following statements regarding the LDP neighbor discovery is false?

A. LDP discovery mechanisms include the basic discovery mechanism and extended discovery mechanism.

B. The LDP basic discovery mechanism discovers directly-connected LDP peers on a link.

C. The LDP extended discovery mechanism discovers indirectly-connected LDP peers.

D. LDP discovery mechanisms need to specify LDP Peer.

Which of the following statements regarding the delay and jitter is true?

A. The jitter is relevant to the delay.

B. The jitter occurs because the E2E delays of data packets in the different flow are different.

C. A long delay indicates a short jitter and a short delay indicates a large jitter.

D. Jitter is independent of delay.

The NAT address pool configuration command is as follows. What is the meaning of no-pat?

A. The address is not translated.

B. The interface is multiplexed.

DHCP snooping is a security feature. Which of the following statements regarding DHCP snooping is false?

A. The DHCP snooping binding table contains dynamic binding entries and static binding entries.

B. DHCP snooping distinguishes the trusted interface and untrusted interfaces. Untrusted interfaces do not process DHCP Reply packets.

C. The static binding table is manually set on the inbound interface and the aging time is also manually set.

D. When DHCP snooping is used at Layer 2, the interface information also can be obtained for the binding table if the Option 82 function is not configured.
