What are two advantages of using LACP? (Choose two.)
LACP allows Fast Ethernet and Gigabit Ethernet
interfaces to be mixed within a single EtherChannel.
It eliminates the need for configuring trunk interfaces
when deploying VLANs on multiple switches.
It allows directly connected switches to negotiate an
EtherChannel link.
It provides a simulated environment for testing link
aggregation.
It allows the use of multivendor devices.
What are two advantages of EtherChannel? (Choose two.)
Configuring the EtherChannel interface provides
consistency in the configuration of the physical links.
Load balancing occurs between links configured as
different EtherChannels.
EtherChannel uses upgraded physical links to provide
increased bandwidth.
Spanning Tree Protocol views the physical links in an
EtherChannel as one logical connection.
Spanning Tree Protocol ensures redundancy by transitioning
failed interfaces in an EtherChannel to a forwarding state.
Which three components are combined to form a bridge ID?
port ID
IP address
extended system ID
MAC address
bridge priority
In which two port states does a switch learn MAC addresses and process BPDUs in a PVST network? (Choose two.)
blocking
disabled
forwarding
learning
listening
If no bridge priority is configured in PVST, which criteria is considered when electing the root bridge?
lowest IP address
lowest MAC address
highest IP address
highest MAC address
Which two network design features require Spanning Tree Protocol (STP) to ensure correct network operation? (Choose two.)
static default routes
implementing VLANs to contain broadcasts
redundant links between Layer 2 switches
link-state dynamic routing that provides redundant
routes
removing single points of failure with multiple Layer 2
switches
What is the outcome of a Layer 2 broadcast storm?
Routers will take over the forwarding of frames as
switches become congested.
New traffic is discarded by the switch because it is
unable to be processed.
CSMA/CD will cause each host to continue transmitting
frames.
ARP broadcast requests are returned to the transmitting
host.
When the show spanning-tree vlan 33command is issued on a switch, three ports are shown in the forwarding state. In which two port roles could these interfaces function while in the forwarding state? (Choose two.)
disabled
designated
root
alternate
blocked
A set of switches is being connected in a LAN topology. Which STP bridge priority value will make it least likely for the switch to be selected as the root?
4096
32768
61440
65535
What is the function of STP in a scalable network?
It decreases the size of the failure domain to contain
the impact of failures.
It protects the edge of the enterprise network from
malicious activity.
It disables redundant paths to eliminate Layer 2 loops.
It combines multiple switch trunk links to act as one
logical link for increased bandwidth.
What is a characteristic of spanning tree?
It is enabled by default on Cisco switches.
It has a TTL mechanism that works at Layer 2.
It prevents propagation of Layer 2 broadcast frames.
It is used to discover information about an adjacent
Cisco device.
Which statement is true regarding the use of PAgP to create EtherChannels?
It requires full duplex.
It is Cisco proprietary.
It requires more physical links than LACP does.
It increases the number of ports that are participating
in spanning tree.
What are two requirements to be able to configure an EtherChannel between two switches? (Choose two.)
The interfaces that are involved need to be contiguous on the switch.
All the interfaces need to work at the same speed.
All the interfaces need to be working in the same
duplex mode.
All interfaces need to be assigned to different VLANs.
Different allowed ranges of VLANs must exist on each
end.
Which two channel group modes would place an interface in a negotiating state using PAgP? (Choose two.)
on
desirable
active
auto
passive
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.
