質問 3：
A consultant is attempting to deploy an AHV cluster, but Foundation did not discover any factory-imaged nodes. The consultant then uses the crash cart script to configure all IP addresses manually.
What step is required for the consultant to continue cluster creation?
A. Create a new cluster, bypassing discovery, by using the flag --skip_discovery.
B. Create a new cluster by using the flag --multicast_static-group.
C. Remove the VLAN igmp unknown-mcast-flood option from the switch configuration.
D. Use the cluster -s IP1, IP2, IP3, IPn create command to create the cluster.

質問 5：
A consultant is completing final network failover testing on a recently deployed AHV cluster.
The cluster consists of the following:
*Three nodes
*Two uplinks connected to two switches
*Supported SFPs
The consultant removed one SFP+ out of each node. Two of the nodes (Hostl I Host2) failed over to the backup NIC correctly without any interruption but have lost communication with the third node (Host 3) hypervisor/CVM. Inserting the original SFP+ back into the problematic node allowed the network to be connected and the two healthy nodes could communicate successfully again.

manage_ovs showjinterfaces output:
name mode link speed
cthO 10000 True 10000
ethl 10000 False None
eth2 10000 True 10000
eth3 10000 False None
manage_ovs show.uplinks output:
Bridge: brO
Bond: brO-up
bond_mode: active-backup
interfaces: ethl ethO
lacp: off
lacp-fa I 1 back: false
lacp_speed: slow
What should the consultant validate first?
A. Validate that the correct interfaces are included in the bridge.
B. Validate the customer has configured all their switch ports identically.
C. Validate NIC card on node is seated properly.
D. Validate the SFP+ is fully plugged into the node and switch.

質問 6：
A customer has provided the following network requirements to their consultant during a discovery session for AHV cluster deployments:
*Maximum Uptime Guest Traffic is a Hard Requirement
*Maximum Throughput for Guest is a Hard Requirement
*Link Aggregation is established at the TORs
Cluster nodes have the following network card configurations:
*2 x 40GbE Adapters
*2 x IGbE Adapters
How should the consultant satisfy these requirements?
A. Bonded 2 x 40GbE Adapters with LACP Disabled for Storage Traffic and Guest Traffic using balance- sib
B. Bonded 2 x 1 GbE Adapters with LACP Enabled for Storage Traffic and Bonded 2 x 40 GbE Adapters for Guest VM Traffic using balance-tcp
C. Bonded 2 x 40GbE Adapters with LACP Enabled for Storage Traffic and Guest Traffic using balance- tcp
D. Bonded 2 x 40GbE Adapters with LACP Disabled for Storage Traffic and bonded 2x1 GbE Adapters for Guest VM Traffic using active-backup
