SWRE Unit 6

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

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

• • EtherChannel

• DTP

• STP

• VTP

What protocol or technology uses source IP to destination IP as a load-balancing mechanism?

• • VTP

• • EtherChannel

• • DTP

• • STP

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

• • auto

• • default

• • passive

• • desirable

• on

A network administrator is reviewing the configuration of switch S1. Which protocol has been implemented to group multiple physical ports into one logical link?

• • PAgP

• • DTP

• • LACP

• STP

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

Which three hosts will receive ARP requests from host A, assuming that port Fa0/4 on both switches is configured to carry traffic for multiple VLANs? (Choose three.)

• B

• C

• D

• E

• F

The network administrator configures both switches as displayed. However, host C is unable to ping host D and host E is unable to ping host F. What action should the administrator take to enable this communication?

• • Associate hosts A and B with VLAN 10 instead of VLAN 1.

• • Configure either trunk port in the dynamic desirable mode.

• • Include a router in the topology.

• • Remove the native VLAN from the trunk.

• • Add the switchport no-negotiate command to the configuration of SW2.

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.

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? (Choose two.)

• • The root bridge BID.

• • The status of native VLAN ports.

• • The role of the ports in all VLANs.

• • The number of broadcasts received on each root port.

• • The IP address of the management VLAN interface.
