   An administrator is configuring an MX7000 fabric for a financial services company. The design includes 300 VLANs for production, 10 VLANs for management, and 5 FCoE VLANs for storage. The administrator is concerned about the impact of FCoE VLANs on the overall VLAN scale. Which statement accurately describes the impact of FCoE VLANs on VLAN scaling?

   • AFCoE VLANs do not count toward the 1024-VLAN limit because they are handled separately by the storage network.
   • BFCoE VLANs consume twice the VLAN resources of regular VLANs, so the effective limit is 512.
   • CFCoE VLANs count toward the 1024-VLAN limit, so the total number of VLANs must be kept within this limit.
   • DFCoE VLANs are only supported on specific IOMs, so they do not affect the overall VLAN scale.

   A service provider is deploying an MX7000 fabric to support multiple customers. Each customer requires a dedicated VLAN for their traffic. The provider wants to maximize the number of customers supported. Which action should the provider take to maximize the number of VLANs available?

   • ADisable FCoE and management VLANs to free up more VLAN IDs for customers.
   • BAllocate a separate VLAN for each customer, up to the 1024-VLAN limit.
   • CUse a single VLAN for all customers and rely on access control lists to isolate traffic.
   • DUse private VLANs to allow multiple customers to share a single VLAN while maintaining isolation.

   A large enterprise is planning an MX7000 fabric to consolidate multiple legacy networks. The design requires 900 VLANs for production traffic, 50 VLANs for management, and 20 FCoE VLANs for storage. The total is 970 VLANs, which is within the 1024 limit. However, the network team is concerned about the impact of oversubscription on the fabric's uplinks. Which additional factor should be considered to ensure the design is viable?

   • AThe VLAN count is within limits, but the fabric's control plane may become unstable with more than 500 VLANs, so the design is not viable.
   • BThe design is viable, but the administrator should verify that the uplink bandwidth is sufficient to handle the aggregated traffic from all VLANs.
   • CThe fabric's uplink oversubscription ratio is fixed and cannot be changed, so the design is not viable if the ratio is too high.
   • DThe design is not viable because FCoE VLANs consume additional resources beyond the VLAN limit, effectively reducing the available VLANs.

   An administrator notices that multicast traffic in an MX7000 fabric is being flooded to all ports in a VLAN, even though IGMP snooping is enabled. The administrator suspects that the multicast group is not being learned correctly. Which action should the administrator take to ensure multicast groups are properly learned and pruned?

   • AIncrease the IGMP query interval to reduce the frequency of group membership updates.
   • BEnable IGMP querier on the VLAN to ensure that group membership is actively maintained.
   • CConfigure a static multicast group entry for the group to force forwarding to specific ports.
   • DDisable IGMP snooping and rely on the router to handle multicast forwarding.

   A company is deploying an MX7000 fabric for a campus network. The network carries multicast traffic for IPTV and audio conferencing. The administrator wants to ensure that multicast traffic is only forwarded to ports that have active subscribers. Which feature should be enabled on the fabric to achieve this?

   • AVLAN pruning
   • BIGMP snooping
   • CIGMP querier
   • DMulticast flooding
