Cisco 2 R&S3 chapter 2 – Flashcards

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

What additional information is contained in the 12-bit extended system ID of a BPDU?

Which three components are combined to form a bridge ID?

Refer to the exhibit. Which trunk link will not forward any traffic after the root bridge election process is complete?

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

Which is the default STP operation mode on Cisco Catalyst switches?

What is an advantage of PVST+?

In which two port states does a switch learn MAC addresses and process BPDUs in a PVST network?

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

To obtain an overview of the spanning tree status of a switched network, a network engineer issues the show spanning-tree command on a switch. Which two items of information will this command display?

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

Which nonproprietary protocol provides router redundancy for a group of routers which support IPv4 LANs?

Refer to the exhibit. Which protocol information is being displayed in the output?

Refer to the exhibit. A network engineer is troubleshooting host connectivity on a LAN that uses a first hop redundancy protocol. Which IPv4 gateway address should be configured on the host?

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

Which two concepts relate to a switch port that is intended to have only end devices attached and intended never to be used to connect to another switch?

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?

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 briefcommand 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?
