Question 11

What impact does server virtualization have on a traditional datacenter network?

A.Traditional network configuration involves manual interaction, which cannot keep up with the dynamic reallocation of compute resources to virtual machines.

B.Server virtualization requires a hardware upgrade of the network devices (for example, TOR/EOR switch, leaf and spine routers) in a traditional datacenter network.

C.Traffic between the virtual machines must be carried in the overlay network, which is not supported by a traditional datacenter network.

D.Server virtualization requires a software upgrade of the network devices (for example, TOR/EOR switch, leaf and spine routers) in a traditional datacenter network.

Question 12

Refer to the diagram.

What is the correct sequence of events for a VM to be instantiated, and for its required network connectivity to be created with the Nuage VCS solution?
a. Network domain and policy templates are defined on VSD. b.
VSC queries VSD on network service and policies. c. VSD provides VSC with network service and policies. d. VRS agent informs VSC of the new VM placement. e. VSC deploys policy to applicable VRS agents. f. VM instantiated on the hypervisor.

A.a->b->c->f->d->-e

B.a->b->c->d->e->f

C.a->f->d->b->c->-e

D.f->d->b->a>c->-e

Question 13

Which domain can be extended to a 7750 DCI by GRE tunnels?

A.An L3 domain.

B.A managed L2 domain.

C.An unmanaged L2 domain.

D.A subnet within an L3 domain.

Question 14

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

A.High latency for some applications.

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

C.Sub-optimal traffic flow.

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

Question 15

What statement about virtual switches is FALSE?

A.Virtual switches are VLAN capable.

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

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

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