B. UDLD protects against STP failures caused by cabling problems that create one-way links.
C. Loop guard detects and protects against duplicate packets being received and transmitted on different ports
D. UDLD protects against unidirectional cabling problems on copper and fiber media.
E. Loop guard protects against STP failures caused by problems that result in the loss of BPDUs from a designated switch port.

In GLBP，which router will answer on client ARP requests？（）
Based on the output provided in the exhibit， to which address or location will the router forward a packet sent to 192.168.32.1？（）
Two routers configured to run BGP have been connected to a firewall， one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer， including the correctBGP session endpoint addresses and the correct BGP session hop-count limit EBGP multihop. What is agood first test to see if BGP will work across the firewall？（）
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？（）
Which of these statements about penultimate hop popping are true？（）
Which two are differences between IGMPv2 and IGMPv3 reports？（）
