In traffic policing, dual buckets at dual rates are used. The number of tokens in bucket C is TC, and the number of tokens in bucket P is TP. When a packet with a length of B is received, which of the following statements are true?

Simple traffic classification in QoS classifies packets based on the 5-tuple information, including the source IP address, source port number, protocol number, destination IP address, and destination port number.

Which of the following statements regarding MPLS is false?

Assuming three routers (A, B, and C) uses BGP as the routing protocol. A sends Update packets to B and B sends the Update packets to C. Which of the following attributes meet the following two conditions? (1) A can select whether to carry this attribute in Update packets. (2) If B receives an Update packet carrying this attribute, B still advertises the Update packet to C although B cannot identify this attribute. Then, Router C may identify and use this attribute.

Most popular Layer 2 tunneling technologies include VXLAN, TRILL, NVGRE, and MPLS.

Which of the following statements about RPs are true? (Choose three.)

The network administrator defines a traffic policy as follows: The router port to which the traffic policy is applied has been idle for about 10 seconds. In this case, if there is suddenly a large amount of c1 burst traffic, what is the number of bytes in the green packets?

As shown in the figure below, R1 and R2 are connected through a PPP link, and the IP addresses on the directly connected interfaces are not on the same network segment. R1 and R2 can communicate with each other through the directly connected interfaces. However, communication on the Ethernet link fails if the IP addresses on the directly connected interfaces are on the same network segment. What are the causes of this?

If multiple candidate RPs are configured in a multicast domain, which of the following parameters need to be compared when electing the RP of the group from multiple candidate RPs?

Which of the following statements regarding the Register message on a PIM-SM network are true?

Which of the following statements regarding OSPFv3 is false?

If no area is divided, which of the following statements regarding the link-state routing protocol are true?

Assume that the traffic shaping rate is set to 100 Mbit/s on an interface and that the input bandwidth and PIR of each service are configured as shown in the table below. What is the bandwidth allocated to the EF queue after the first round of scheduling?

Regular expressions can be used in Community-filter and AS-Path-filter to filter routes.

The figure shows router data. Which of the following statements is false?

When a router receives an LSP on a broadcast network or a P2P network enabled with IS-IS, the router needs to send a PSNP to ensure LSDB synchronization.

To deploy multicast video applications on your private internal network, you need to use private multicast IP addresses on the network. Which range of IP addresses can be used?

What are the differences between traffic policing and traffic shaping?

Which of the following statements regarding IS-IS route summarization is true?

Which of the following are found in a basic Network Layer Packet?
