All of these are fundamental building blocks of differentiated services Traffic Conditioner Block exceptwhich one？（）

What is the command to configure RSVP to reserve up to one-tenth of a Gigabit link，but only allow eachindividual flow to use 1 MB/s？（）

The classic Spanning Tree Protocol （802.1 D 1998） uses which sequence of variables to determine thebest received BPDU？（）

In PIM-SM what control plane signaling must a multicast source perform before it begins to send multicasttraffic to a group？（）

How does an IPv6 router deal with a packet that is larger than the outgoing interface MTU？（）

An expanding company is deploying leased lines between its main site and two remote sites. Thebandwidth of the leased lines is 128kb/s each，terminated on different serial interfaces on the main router.These links are used for combined VOIP and data traffic. The network administrator has implemented a VOIP solution to reduce costs，and has therefore reserved sufficient bandwidth in a low latency queue oneach interface for the VOIP traffic. Users now complain about bad voice quality although no drops areobserved in the low latency queue. What action will likely fix this problem？（）

On the basis of the network provided in the exhibit， all routers are configured to run EIGRP on all links. If the link between PG-R1 and PG-R2 fails， what is the maximum number of queries PG-R3 will receive for 192.168.1.0/24， assuming that all the packets sent during convergence are transmitted once （there are no dropped or retransmitted packets）？（）

Which message type is constructed and sent from an MSDP router to its MSDP peers when it receives a PIM register message knowing that the MSDP router is also configured as an RP for the PIM domain？（）
