324 Chapter 6 � Virtual LANs (VLANs)
11. D. By default, if you create a trunked link, all VLANs are allowed on
that trunked link. You must delete any unwanted VLANs by hand.
12. B. Switches look for a revision number plus 1. If that is found, they
will delete their database and update the VLAN database with the new
VLAN information.
13. C. 802.1q was created to allow trunked links between disparate
switches.
14. A, D. Trunks are used to carry VLAN information between switches.
15. B, C. When a frame traverses a trunked link, it is encapsulated in ISL
information. The ISL information is removed before the frame is sent
down an access link.
16. D. Access links only carry information about one VLAN.
17. D. 802.1q is the IEEE standard for identifying VLANs as they cross a
trunked link.
18. C. Transparent VTP mode passes VTP information through trunked
links but does not update the VTP database with VTP information
from a VTP server.
19. C. An ISL header is 26 bytes long.
20. B. Cisco created frame tagging to be used when an Ethernet frame
traverses a trunked link.
