E .  An MST region is a group of MST switches that appear as a single virtual bridge to adjacent  CST and MST regions. F .  Enabling MST with the "spanning-tree modemst" global configuration command also enables  RSTP.

A . Cisco Discovery Protocol B . Label Discovery Protocol C . Border Gateway Protocol D . OSPF E . RIP version 2

A . There are three IGMP modes: dense mode, sparse mode, and sparse - dense mode B . IGMP is used to register individual hosts with a multicast group C . IGMP version 3 enables a multicast receiving host to specify to the router which sources it should forward traffic from D . IGMP messages a re IP datagrams with a protocol value of 2, destination address of 224.0.0.2, and a TTL value of 1 E . IGMP is a multicast routing protocol that makes packet - forwarding decisions independent of other routing protocols such as EIGRP F . IGMP snooping ru ns on Layer 3 router

A . Over leased lines，use the multilink ppp command to reduce latency and jitter，and to create Distributed Link Fragmentation and interleaving. B . Use the service-policy command to attach a traffic flow to an interface on the router. C . Use the ip rsvp bandwidth command to set a strict upper limit on the bandwidth NBAR uses，and toguarantee admission of any flows. D . Use the policy-map command to define one or more QoS policies （such as shaping，policing，and so on） to apply to traffic defined by a class map. E . Use the random-detect dscp command to modify the default minimum and maximum thresholds for the DSCP value. F . Use the class-map command to define one or more traffic classes by specifying the criteria by which traffic is classified.

A . LDAP B . ICMP C . RTP D . BGP E . SSH F . RDP

A .  H·323 B .  UDP C .  RTP D .  TCP E .  Media Gateway Control Protocol （MGCP） F .  session initiation protocol （SIP）

A .  IGRP B .  RIP C .  RIPv2 D .  OSPF

A . EIGRP supports five generic packet types, including hello, database description (DBD), link state request (LSR), link - state update (LSU), and LSAck. B . EIGRP sends periodic hello packets to the multicast IP address 224.0.0.10. C . EIGRP will not form a neighbor relationship with another peer when their K values are mismatched. D . EIGRP sends periodic hello packets to the multicast IP address 224.0.0.9. E . E IGRP will form a neighbor relationship with another peer even when their K values are mismatched. F . EIGRP supports five generic packet types, including hello, update, query, reply, and ACK packets.
