A network administrator configured an EtherChannel link with three interfaces between two switches. What is the result if one of the three interfaces is down? a The EtherChannel fails. b The remaining two interfaces continue to load balance traffic. c The remaining two interfaces become separate links between the two switches. d One interface becomes an active link for data traffic and the other becomes a backup link.
b
A network administrator is analyzing first-hop router redundancy protocols. What is a characteristic of VRRPv3? a VRRPv3 is Cisco proprietary. b It supports IPv6 and IPv4 addressing. c It works together with HSRP. d It allows load balancing between routers.
a
A network administrator is analyzing the features that are supported by different first-hop router redundancy protocols. Which statement describes a feature that is associated with HSRP? a HSRP uses active and standby routers. b It uses ICMP messages in order to assign the default gateway to hosts. c It allows load balancing between a group of redundant routers. d HSRP is nonproprietary.

A network administrator is analyzing the features that are supported by different first-hop router redundancy protocols. Which statement is a feature that is associated with GLBP? a GLBP allows load balancing between routers. b It is nonproprietary. c It uses a virtual router master. d It works together with VRRP.
b
As the network administrator you have been asked to implement EtherChannel on the corporate network. What does this configuration consist of? a providing redundant links that dynamically block or forward traffic b grouping multiple physical ports to increase bandwidth between two switches c grouping two devices to share a virtual IP address d providing redundant devices to allow traffic to flow in the event of device failure
a, d
What are two advantages of EtherChannel? (Choose two.) a Configuring the EtherChannel interface provides consistency in the configuration of the physical links. b Load balancing occurs between links configured as different EtherChannels. c EtherChannel uses upgraded physical links to provide increased bandwidth. d Spanning Tree Protocol views the physical links in an EtherChannel as one logical connection. e Spanning Tree Protocol ensures redundancy by transitioning failed interfaces in an EtherChannel to a forwarding state.
b, e
What are two load-balancing methods in the EtherChannel technology? (Choose two.) a combination of source port and IP to destination port and IP b source IP to destination IP c source port to destination port d combination of source MAC and IP to destination MAC and IP e source MAC to destination MAC
c
When EtherChannel is configured, which mode will force an interface into a port channel without exchanging aggregation protocol packets? a active b auto c on d desirable
d
When EtherChannel is implemented, multiple physical interfaces are bundled into which type of logical connection? a interface range b loopback c VLAN interface d port channel
d
When a range of ports is being configured for EtherChannel, which mode will configure LACP on a port only if the port receives LACP packets from another device? a active b auto c desirable d passive
d
Which command will start the process to bundle two physical interfaces to create an EtherChannel group via LACP? a channel-group 2 mode auto b interface port-channel 2 c channel-group 1 mode desirable d interface range GigabitEthernet 0/4 - 5
a
Which mode configuration setting would allow formation of an EtherChannel link between switches SW1 and SW2 without sending negotiation traffic? a SW1: on SW2: on b SW1: desirable SW2: desirable c SW1: auto SW2: auto trunking enabled on both switches d SW1: auto SW2: auto PortFast enabled on both switches e SW1: passive SW2: active
b, d
Which two channel group modes would place an interface in a negotiating state using PAgP? (Choose two.) a on b desirable c active d auto e passive
b, c
Which two parameters must match on the ports of two switches to create a PAgP EtherChannel between the switches? (Choose two.) a MAC address b speed c VLAN information d PAgP mode e port ID
