4A0-N01 Free Questions – Nuage Networks Virtualized Cloud Services (VCS) Fundamentals Exam – PassQuestion Free Questions To Test Online

1. What benefits does virtualization bring to a data center?

Mobility, flexibility, and better resource utilization.

Multitasking with prioritized process scheduling.

More processing power, memory and disk space.

Higher bandwidth, control plane simplification and reduced forwarding tables.

2. What statement best describes the concept of Policy-Based Automation provided by Nuage Networks?

The virtual machines are automatically instantiated according to the specific policy defined in the CMS.

Network devices as TOR/EOR switch, and leaf/spine routers, are automatically provisioned based on the configuration policy.

The Nuage Networks VCS solution can integrate with any CMS, operate on any hypervisor, and be deployed in any data center network.

The overlay network instances are automatically created according to the configuration details defined in a specific policy.

3. What occurrence is NOT a problem facing a traditional data center network?

High packet loss due to the use of the 3-tier hierarchy.

Sub-optimal traffic flow.

About half of the bandwidth is not used due to links being disabled by STP.

High latency for some applications.

4. Which of the following is a host-centric overlay solution for a modern data center?

SPBM

TRILL

VxLAN

VPLS

5. Which statement about SDN is correct?

Network control is fully integrated into the forwarding plane.

SDN supports cloud computing by automating virtual machine instantiation.

The API interface provides a way to program the SDN switch directly.

The SDN controller provides global provisioning of network devices.

6. 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.

7. 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.

8. 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
