CCNA 3 CHP 2

What is an advantage of PVST+?

PVST+ optimizes performance on the network through load sharing.*

Match the step number to the sequence of stages that occur during the HSRP failover process.

Place the options in the following order: The new forwarding router assumes both the IP and MAC address of the virtual router. -> Step 4 - not scored - The standby router assumes the role of the forwarding router. -> Step 3 The forwarding router fails. -> Step 1 The standby router stops seeing hello messages from the forwarding router. -> Step 2

What could be the effect of duplicate unicast frames arriving at a destination device due to multiple active alternative physical paths?

Application protocols malfunction.*

Which Cisco switch feature ensures that configured switch edge ports do not cause Layer 2 loops if a port is mistakenly connected to another switch?

A network administrator is preparing the implementation of Rapid PVST+ on a production network. How are the Rapid PVST+ link types determined on the switch interfaces?

Link types are determined automatically.*

What value determines the root bridge when all switches connected by trunk links have default STP configurations?

MAC address*

MST*

What is the outcome of a Layer 2 broadcast storm?

New traffic is discarded by the switch because it is unable to be processed.*

Which two network design features require Spanning Tree Protocol (STP) to ensure correct network operation?

redundant links between Layer 2 switches removing single points of failure with multiple Layer 2 switches

Which STP port role is adopted by a switch port if there is no other port with a lower cost to the root bridge?

root port*

Which STP priority configuration would ensure that a switch would always be the root switch?

Refer to the exhibit. A network administrator configured routers R1 and R2 as part of HSRP group 1. After the routers have been reloaded, a user on Host1 complained of lack of connectivity to the Internet The network administrator issued the show standby brief command on both routers to verify the HSRP operations. In addition, the administrator observed the ARP table on Host1. Which entry should be seen in the ARP table on Host1 in order to gain connectivity to the Internet?
