Question
Which of the following can be used to optimize the bandwidth between connected switches?
Options
- APort groups
- BTrunking
- CISL
- DRouting
Explanation
Trunking is a method that allows multiple physical links between switches to be bundled together, increasing the aggregate bandwidth and providing redundancy.
Common mistakes.
- A. Port groups typically refer to logical groupings of virtual machine network adapters on a virtual switch, not a mechanism to optimize bandwidth between physical switches.
- C. ISL (Inter-Switch Link) is a Cisco-proprietary trunking protocol for carrying multiple VLANs over a single link, but 'trunking' is the broader concept for bandwidth optimization itself.
- D. Routing determines the path for network traffic between different networks and does not directly optimize bandwidth between two connected switches on the same network segment.
