NEW QUESTION 24
What statement correctly describes the difference between a managed Layer 2 domain and an undamaged Layer 2 domain?
- A. In a managed L2 domain, Nuage Networks VCS manages security policies, while in an unmanaged domain, Nuage Networks VCS cannot manage the security policies.
- B. Managed L2 domains can have overlapping IP address pools, while unmanaged L2 domains are not allowed to have overlapping IP address pools.
- C. A managed L2 domain has one or more zones and each zone can have multiple subnets, each with its own IP address pool, while an unmanaged L2 domain does not have zones or subnets.
- D. In a managed L2 domain, Nuage Networks VCS performs DHCP and ARP proxy functions, while in an unmanaged domain VCS has no visibility of IP addresses.
Answer: B
NEW QUESTION 25
What statement is TRUE regarding multiple virtual IP addresses assigned to a single vPort?
- A. One of the virtual IP addresses can be the same as the VM interface IP address.
- B. All virtual IP addresses of a vPort must be in the same subnet.
- C. Every virtual IP address must be associated with a virtual MAC, which differs from the VM interface
MAC address. - D. The virtual IP addresses can be in a different subnet than the VM interface IP address.
Answer: D
Explanation:
Explanation
If you have only one public IP address available, and you want to host multiple servers, use aVIP.

- B. Step a, which consists of defining network domain and policy templates on VSD, must be performed first in all situations.
- C. Step d, which refers to the VRS agent informing the VSC of the placement of a new VM, is triggered by step f in which the VM is instantiated on a hypervisor.
- D. Step e, in which the forwarding tables are deployed, consists of the VSC sending them not only to the VRS agent hosting the new VM, but to all applicable VRS agents.
Answer: D
NEW QUESTION 30
