What is the value used to determine which port on a non-root bridge will become a root port in a STP network?
the highest MAC address of all the ports in the switchthe lowest MAC address of all the ports in the switch
the VTP revision number
the path cost*
Which three STP states were replaced with the RSTP discarding state? (Choose three.)
As the network administrator you have been asked to implement EtherChannel on the corporate network. What does this configuration consist of?
providing redundant links that dynamically block or forward traffic
grouping multiple physical ports to increase bandwidth between two switches*
grouping two devices to share a virtual IP address
providing redundant devices to allow traffic to flow in the event of device failure
Which command will start the process to bundle two physical interfaces to create an EtherChannel group via LACP?
channel-group 2 mode autointerface port-channel 2
channel-group 1 mode desirable
interface range GigabitEthernet 0/4 – 5*
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?
The EtherChannel fails.
The remaining two interfaces continue to load balance traffic.*
The remaining two interfaces become separate links between the two switches.
One interface becomes an active link for data traffic and the other becomes a backup link.
When EtherChannel is configured, which mode will force an interface into a port channel without exchanging aggregation protocol packets?
Refer to the exhibit.A network administrator is reviewing the configuration of switch S1. Which protocol has been implemented to group multiple physical ports into one logical link?
What is the term used to describe a network topology where the subnets from a major classful network address space are separated from each other by addresses from a different major classful network address?
multihomed networkconverged network
What type of packets are sent when there is a change in the EIGRP topology?
triggered bounded update*
Which three pieces of information does a link-state routing protocol use initially as link-state information for locally connected links? (Choose three.)
the link router interface IP address and subnet mask*
the type of network link*
the link next-hop IP address
the link bandwidth
the cost of that link*
What indicates to a link-state router that a neighbor is unreachable?
if the router no longer receives routing updates
if the router no longer receives hello packets*
if the router receives an update with a hop count of 16
if the router receives an LSP with previously learned information
What are three features of EIGRP? (Choose three.)
uses the Shortest Path First algorithm
establishes neighbor adjacencies*
uses the Reliable Transport Protocol*
sends full routing table updates periodically
broadcasts updates to all EIGRP routers
supports equal and unequal cost load balancing*
What capability do protocol-dependent modules provide to the EIGRP routing protocol?
route different Layer 3 protocols*
exchange summary routes between areas
combine routes learned from different protocols into a single routing table
load balance between routing protocols
Which command should be used to configure EIGRP to only advertise the network that is attached to the gigabit Ethernet 0/1 interface?
network 172.16.23.64 0.0.0.63*
network 172.16.23.0 255.255.255.192
network 172.16.23.64 0.0.0.127
network 172.16.23.0 255.255.255.128
Which command will configure an IPv6 default static route?
router(config)# ipv6 ::/64 s0/0/0router(config-rtr)# redistribute static
router(config)# ipv6 route ::/0 s0/0/0*
router(config)# ipv6 unicast-routing
