Question 2
What information is included in the VTEP (virtual tunnel endpoint) forwarding table?
- The remote VM IP addresses, the VXLAN ID (VNI) and the remote VTEP.
- The remote VM MAC addresses, the VXLAN ID (VNI) and the remote VTEP.
- The remote VM IP addresses, the VXLAN ID (VNI) and the local VTEP.
- The remote VM MAC addresses, the VXLAN ID (VNI) and the local VTEP.
Correct answer: A
Explanation:
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 IP address is the remote VTEP IP address or the IP Multicast group address

Question 3
What statement about virtual switches is FALSE?
- A virtual switch is typically implemented within the hypervisor so that the network is extended onto the server.
- Virtual switches are VLAN capable.
- Typically, virtual switches are as capable as physical switches, eg: LAG, hardware-based QoS.
- If a virtual switch is not on the hypervisor, all traffic will go out of the physical NIC.
Correct answer: D
Question 4
What is NOT a requirement for modern data center networks to facilitate cloud computing?
- Multi-tenancy
- Network automation
- Virtual machine live migration
- Network function virtualization
Correct answer: D
Question 5
If we compare a Nuage Virtual Service Node to a physical service router, which module is VSC mapped to?
- Switch fabric
- Line card
- CPU module
- Internal clock
Correct answer: A
Explanation:
The switching fabric is independent of the bus technology and infrastructure used to move data between nodes and also separate from the router. The term is sometimes used to mean collectively all switching hardware and software in a network.

Question 6
What statement is FALSE regarding the relationship between a zone and a subnet within a domain?
- Each zone can have multiple subnets.
- Each subnet can belong to multiple zones.
- A QoS policy defined at the subnet level takes precedence over a QoS policy defined at the zone level.
- A security policy applied to the zone impacts all subnets associated to that zone.
Correct answer: B
Question 7

Question 9
What statement regarding VSD user management is TRUE?
- We can create CMS user groups for each enterprise.
- Each enterprise user belongs to only one user group.
- Open LDAP and Active Directory can be integrated into VSD.
- LDAP integration is configured at the VSD global level, and it is not configurable enterprise.
Correct answer: B
