Which of the following devices performs transparent bridging?
a. Ethernet hub
b. Layer 2 switch
c. Layer 3 switch
Layer 2 switch
When a PC is connected to a Layer 2 switch port, how far does the collision domain spread?
One switch port.
What information is used to forward frames in a Layer 2 switch?
Destination MAC address
What does a switch do if a MAC address cannot be found in the CAM table?
The switch floods the frame out all ports (except the receiving port).
In the Catalyst 6500, frames can be filtered with access lists for security and QoS
purposes. This filtering occurs according to what?
Simultaneously with a CAM table lookup
Access list contents can be merged into which table?
Multilayer switches using CEF are based on which of these techniques?
a. Route caching
b. Netflow switching
c. Topology-based switching
d. Demand-based switching
Which answer describes multilayer switching with CEF?
A. The first packet is routed and then the flow is cached.
B. The switching hardware learns station addresses and builds a routing database.
C. The switch supervisor CPU forwards each packet.
D. A single database of routing information is built for the switching hardware.
D. A single database of routing information is built for the switching hardware
In a switch, frames are placed in which buffer after forwarding decisions are made?
What size are the mask and pattern fields in a TCAM entry?
Access list rules are compiled as TCAM entries. When a packet is matched against an
access list, in what order are the TCAM entries evaluated?
All entries are evaluated in parallel.
Which Catalyst IOS command can you use to display the addresses in the CAM table?
show mac address-table
