SRWE-Refreshing Activity 2

Refer to the Figure. A network administrator has connected two switches together using EtherChannel technology. If STP is running, what will be the end result?

• The switches will load balance and utilize both EtherChannels to forward packets.

• Both port channels will shutdown.

• The resulting loop will create a broadcast storm.

• STP will block one of the redundant links.

What protocol or technology disables redundant paths to eliminate Layer 2 loops?

• VLAN Trunking Protocol (VTP)

• Spanning Tree Protocol (STP)

• EtherChannel

• Dynamic Trunking Protocol (DTP)

Refer to the figure. All the displayed switches are Cisco 2960 switches with the same default priority and operating at the same bandwidth. Which three ports will be STP designated ports? (Choose three.)

• fa0/9

• fa0/10

• fa0/11

• fa0/21

Which command will start the process to bundle two physical interfaces to create an EtherChannel group via LACP?

• interface port-channel 2

• channel-group 1 mode desirable

• interface range GigabitEthernet 0/4 – 5

• channel-group 2 mode auto

Select the three PAgP channel establishment modes. (Choose three)

• Auto

• Desirable

• Default

• On

Which network attack is mitigated by enabling BPDU guard?

• rogue switches on a network

• CAM table overflow attacks

• MAC address spoofing

• rogue DHCP servers on a network

What protocol or technology allows data to transmit over redundant switch links?

• VTP

• STP

• DTP

• EtherChannel

What is the effect of entering the shutdown configuration command on a switch?

• It enables BPDU guard on a specific port

• It disables an unused port

• It enables portfast on a specific switch interface

• It disables DTP on a non-trunking interface

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

• Trunk 1

• Trunk 2

• Trunk 3

• Trunk 4

What is the primary purpose of the Spanning Tree Protocol (STP) in a network?

• To provide redundancy in Layer 3 routing

• To prevent Layer 2 loops in a network

• To manage VLAN configurations

• To enable faster data transmission
