| Question ID 18577 | Which three statements about VTP version 3 are true? (Choose three.)
|
| Option A | It supports other databases in addition to VLAN.
|
| Option B | It supports VLANs up to 4095.
|
| Option C | It supports the synchronization of switch configuration templates between switches in the domain.
|
| Option D | It supports the transfer of information about private VLAN structures.
|
| Option E | It supports the transfer of PVST+ configuration information.
|
| Option F | It supports RSTP.
|
| Correct Answer | A,B,D |
Explanation Explanation: Much work has gone into improving the usability of VTP version 3 in three major areas: The new version of VTP offers better administrative control over which device is allowed to update other devices' view of the VLAN topology. The chance of unintended and disruptive changes is significantly reduced, and availability is increased. The reduced risk of unintended changes will ease the change process and help speed deployment. Functionality for the VLAN environment has been significantly expanded. Two enhancements are most beneficial for today's networks: In addition to supporting the earlier ISL VLAN range from 1 to 1001, the new version supports the whole IEEE 802.1Q VLAN range up to 4095. In addition to supporting the concept of normal VLANs, VTP version 3 can transfer information regarding Private VLAN (PVLAN) structures. The third area of major improvement is support for databases other than VLAN (for example, MST).

| Question ID 18578 | Refer to the exhibit.
Which two statements about the implementation are true? (Choose two.)
|
| Option A | The PPP multilink protocol header is omitted on delay-sensitive packets.
|
| Option B | The maximum number of fragments is 1.
|
| Option C | Small real-time packets are multilink-encapsulated.
|
| Option D | A transmit queue is provided for smaller packets.
|
| Correct Answer | A,D |
Explanation Explanation: Previous implementations of Cisco IOS Multilink PPP (MLP) include support for Link Fragmentation Interleaving (LFI). This feature allows the delivery of delay-sensitive packets, such as the packets of a Voice call, to be expedited by omitting the PPP Multilink Protocol header and sending the packets as raw PPP packets in between the fragments of larger data packets. This feature works well on bundles consisting of a single link. However, when the bundle contains multiple links there is no way to keep the interleaved packets in sequence with respect to each other. The Multiclass Multilink PPP (MCMP) feature in Cisco IOS Release 12.2(13)T addresses the limitations of MLP LFI on bundles containing multiple links by introducing multiple data classes. With multiclass multilink PPP interleaving, large packets can be multilink-encapsulated and fragmented into smaller packets to satisfy the delay requirements of real-time voice traffic; small real-time packets, which are not multilink encapsulated, are transmitted between fragments of the large packets. The interleaving feature also provides a special transmit queue for the smaller, delay-sensitive packets, enabling them to be transmitted earlier than other flows. Interleaving provides the delay bounds for delay-sensitive voice packets on a slow link that is used for other best-effort traffic.
