MLD snooping answer "It can be enabled on VLAN 1 to 1001 only" is wrong. Think "It independent of IGMP snooping" should be used instead.

I agree with this: This statements are clear fro the docs:

  • When the IPv6 multicast router is a Catalyst 6500 switch and you are using extended VLANs (in the range 1006 to 4094), IPv6 MLD snooping must be enabled on the extended VLAN on the Catalyst 6500 switch in order for the Catalyst 3560 switch to receive queries on the VLAN. For normal-range VLANs (1 to 1005), it is not necessary to enable IPv6 MLD snooping on the VLAN on the Catalyst 6500 switch.
  • MLD snooping and IGMP snooping act independently of each other. You can enable both features at the same time on the switch.

 

It can be enabled from vlan 1 - 1005 . On the questions it says Vlans 1 - 1001 only...

Correctly pointed..... Thanks Dear

=========================================

Q: Which two statements correctly describe MLD snooping? (Choose two.)

 

A. It is independent of IGMP snooping

B. It can be disabled globally and then enabled on individual VLANs

C. Global configurations override VLAN configurations

D. It can be enabled on VLANs 1 through 1001 only

E. VLAN query values override global values

 

Ans: A & E

 

As per Cisco URL :

IS-IS Single-Topology Support for IPv6

 

Single-topology support for IPv6 allows IS-IS for IPv6 to be configured on interfaces along with other network protocols (for example, IPv4 and Connectionless Network Service [CLNS]). All interfaces must be configured with the identical set of network address families. In addition, all routers in the IS-IS area (for Level 1 routing) or the domain (for Level 2 routing) must support the identical set of network layer address families on all interfaces.

When single-topology support for IPv6 is being used, either old- or new-style TLVs may be used. However, the TLVs used to advertise reachability to IPv6 prefixes use extended metrics. Cisco routers do not allow an interface metric to be set to a value greater than 63 if the configuration is not set to support only new-style TLVs for IPv4. In single-topology IPv6 mode, the configured metric is always the same for both IPv4 and IPv6.

What is this question and i believe it is not there in 100 Question. Am i missed anything here?
