A single core router provides all the routing between VLANs.
The failure of a switch block will not impact all end users.
This is a security feature that is available on all new Catalyst switches.
This is network application software that prevents the failure of a single network device.
Ability to build a routing table
Ability to aggregate multiple ports for maximum data throughput
Ability to provide power to directly-attached devices and the switch itself
Ability to have multiple forwarding paths through the switched network based on VLAN number(s)
Broadcast traffic containment
Power over Ethernet
Speed of convergence
Connect remote networks
Provide Power over Ethernet to devices
Connect users to the network
Provide data traffic security
Provide a high-speed network backbone

Any switch port will be error-disabled if it receives a BPDU.
Any trunk ports will be allowed to connect to the network immediately, rather than waiting to converge.
Any switch port that has been configured with PortFast will be error-disabled if it receives a BPDU.
Any switch port that receives a BPDU will ignore the BPDU message.
S1 will set the priority value for VLAN 10 to 0.
S2 will set the priority value for VLAN 10 to 24576.
S3 will set the priority value for VLAN 30 to 8192.
S1 will set the priority value for VLAN 20 to 24596.
MAC address of the forwarding router
MAC addresses of both the forwarding and standby routers
MAC address of the standby router

GLBP allows load balancing between routers.
It is nonproprietary.
It uses a virtual router master.
It works together with VRRP.
HSRP uses active and standby routers.
It uses ICMP messages in order to assign the default gateway to hosts
It allows load balancing between a group of redundant routers.
HSRP is nonproprietary.
Spreading traffic across multiple physical WAN links
Dividing the bandwidth of a single link into separate time slots
Enabling traffic from multiple VLANs to travel over a single Layer 2 link
Creating one logical link by using multiple physical links between two LAN switches
SW1: on SW2: on
SW1: desirable SW2: desirable
SW1: auto SW2: auto trunking enabled on both switches
SW1: auto SW2: auto PortFast enabled on both switches
SW1: passive SW2: active
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 di푣erent VLANs.
The EtherChannel is down.
The port channel ID is 2.
The port channel is a Layer 3 channel.
The bundle is fully operational.
The load-balancing method used is source port to destination port.
Clustering mode must be enabled on the APs.
At least two controllers are needed to form the cluster.
The APs have to be connected on the same network segment.
The APs must all be configured to use different radio modes.
The APs must use different cluster names.
Decrease the power of the wireless transmitter.
Add another access point.
Upgrade the access point to one that can route.
Adjust the wireless NICs in the laptops to operate at 10GHz to be compatible with 802.11n.
Ad hoc mode
Sending an ARP request
Delivering a broadcast frame
Transmitting a probe request
Initiating a three-way handshake
Receiving a broadcast beacon frame
WPA2 with TKIP
WPA2 with AES
Split the wireless traffic between the 802.11n 2.4 GHz band and the 5 GHz band.
Change the authentication method on the AP.
Switch to an 802.11g AP.
Set the AP to mixed mode.
