A.Loop guard can be used with root guard simultaneously on the same port on the same VLAN while UDLD cannot.
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.
Refer to the exhibit. Catalyst R is the root bridge for both VLAN 1 and VLAN 2. What is the easiest way to load-share traffic across both trunks and maintain redundancy in case a link fails，without using any type of EtherChannel link-bundling？ （）
A.Increase the root bridge priority （increasing the numerical priority number） for VLAN 2 on Catalyst D so that port D2 becomes the root port on Catalyst D for VLAN 2
B.Decrease the port priority on R2 for VLAN 2 on Catalyst R so that port D1 will be blocked for VLAN 2 and port D2 will remain blocked for VLAN 1
C.Decrease the path cost on R2 on Catalyst R for VLAN 2 so that port D1 will be blocked for VLAN 2 and port D2 will remain blocked for VLAN 1
D.Increase the root bridge priority （decreasing the numerical priority number） for VLAN 2 onCatalyst R so that R2 becomes the root port on Catalyst D for VLAN 2

Refer to the exhibit. In this network，R1 is configured not to perform autosummarization within EIGRP. What routes will R3 learn from R2 through EIGRP？（）
A.172.30.1.0/24 and 10.1.2.0/24；EIGRP only performs autosummarization at the edge between two major networks
B.172.30.0.0/16 and 10.1.2.0/24；R2 will perform autosummarization，although R1 will not
C.Since R2 is configured without autosummarization，it will not propagate the 172.30.1.0/24 route
D.172.30.0.0/8 and 10.0.0.0/8
