Answers
1. | C The 3550 uses a TCAM for searching the forwarding tables. |
2. | B The 2950 switch uses a shared memory switching fabric. |
3. | B Non-blocking switches have sufficient built-in capacity to ensure that frames are forwarded without delay being introduced by waiting for fabric availability. |
4. | A TCAM looks for matches of '1s' '0s' and 'don't cares.' |
5. | A Particle buffering uses small blocks of memory, called particles, to create buffers as needed. |
6. | C The command show buffers is used to display both the system and interface buffers in IOS. |
7. | B, D The command disable debug all is used to stop all debugging activity on an IOS-based switch. |
8. | C CMS is the Cluster Management Suite. |
9. | B The two chassis options currently available are the 4003 and the 4006. |
10. | A VLAN information is held in a separate database, and stored under the name vlan.dat in flash. |
11. | D TCAM lookup can be performed on any structure where addresses contain masks, including Layer 2, Layer 3, and ACL lookups. |
12. | B Switches are said to be running hybrid software when they have CatOS on the switch and IOS on the router. |
13. | C EI is the abbreviation of Enhanced Image. |
14. | A, B, C, D EI supports all of the possible options. |
15. | A The command show cam dynamic shows the dynamically discovered MAC addresses. |
16. | D The 3550 series switches all use a distributed shared-memory switching architecture. |
17. | A A particle buffer is a logically contiguous buffer constructed from particles of memory. |
18. | A With Content Addressable Memory (CAM), a precise relationship exists between the information in the data and its location in the data store. |
19. | B Different interfaces on a router support different MTUs. Different buffer sizes are created at switch-on to support the different MTUs. |
20. | A, D The NAM is a remote monitoring and analysis tool used with the 6500 series switches. It does not perform remote configuration changes. |
