How does traffic flow on the StackWise 3750 platform?
- A.Directionally at 32 Gb/s
- B.Bidirectionally at 32 Gb/s
- C.Counter rotation paths at 16 Gb/s each
- D.Counter rotation paths at 32 Gb/s each
- Answer & Explanation
- Report
Answer : [C]
Explanation :
Explanation :
| The StackWise 3750 has a backend loop of two counter-rotating rings. Each ring supplies 16 Gb/s in each direction. This allows for up to 32 Gb/s total traffic flow and also allows for redundancy. |

You have three switches with LAN Base and two switches with IP Base features
sets. You want to stack the switches together. What needs to be done?
- A.Upgrade the three switches from LAN Base to IP Base.
- B.Downgrade the two switches from IP Base to LAN base.
- C.The switch stack will upgrade or downgrade the IOS according to the master switch.
- D.All of the above
- Answer & Explanation

Answer : [D]
Explanation :
Explanation :
| When you create a switch stack, the subordinate switches will upgrade or downgrade the IOS software according to the master switch’s IOS. Legally, you must purchase the highest IOS the master switch contains or downgrade the license the master contains. |

You have several switches configured in a switch stack configuration. You want to
make the EtherChannel resilient to failure. Which feature should you use?
- A.OSPF
- B.PAgP
- C.Cross-stack EtherChannel
- D.EtherChannel load-balancing
- Answer & Explanation
- Report
Answer : [C]
Explanation :
Explanation :
| Cross-stack EtherChannel allows you to configure EtherChannels between physical switches to act as one EtherChannel. If one switch or SPF transceiver goes bad, the rest of the switching will be supported by the other physical switches. |

You have several 3750 switches located in the same switch closet. You need to
add another switch but are out of Gigabit uplink ports. Which technology could you
employ with these switches for optimal bandwidth?
- A.Switch clustering
- B.Switch stacking
- C.Daisy chaining the Gigabit ports
- D.EtherChannel
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| Switch stacking allows for all of the switches to be tied together so the uplink port can be shared at a nominal bandwidth of 32 Gb/s for the backplane loop. |
