Question 1

What statement is TRUE regarding the workflow for live migration of a virtual machine with Nuage Networks VCS?

AOnly the destination hypervisor's VRS agent notifies the VSC of the VM migration.

BBoth the source and destination hypervisor's VRS agents notify the VSC of the VM migration.

CVSD is not notified of the VM migration.

DCMS (if used) is not notified of the VM migration.

Answer : B

Question 2

What statement about virtual switches is FALSE?

AA virtual switch is typically implemented within the hypervisor so that the network is extended onto the server.

BVirtual switches are VLAN capable.

CTypically, virtual switches are as capable as physical switches, eg: LAG, hardware-based QoS.

DIf a virtual switch is not on the hypervisor, all traffic will go out of the physical NIC.

Answer : D

What statement about floating public IP addresses in the Nuage Networks environment is CORRECT?

AThey are managed by enterprise admin users.

BNAT is performed for the traffic leaving the enterprise domain and entering the public network.

COnce a floating IP is configured on the vPort, the VM will stop using its enterprise private IP address.

DThere can be more than one floating IP address associated with one vPort.

Answer : D

Question 7

What information is included in the VTEP (virtual tunnel endpoint) forwarding table?

AThe remote VM IP addresses, the VXLAN ID (VNI) and the remote VTEP.

BThe remote VM MAC addresses, the VXLAN ID (VNI) and the remote VTEP.

CThe remote VM IP addresses, the VXLAN ID (VNI) and the local VTEP.

DThe remote VM MAC addresses, the VXLAN ID (VNI) and the local VTEP.

Answer : A

IP address is the remote VTEP IP address or the IP Multicast group address Reference: https://sites.google.com/site/amitsciscozone/home/data-center/vxlan
