a) NFVSDN
b) NFVCOTS
c) NFVI
d) NFVIND

2.- is a variety of technologies for managing computer resources by providing an abstraction layer between the software and the physical hardware.

a) Open Platform for NFV
b) Business support system
c) Virtualization
d) Virtual Machine

3.-________ is a subjective measure of performance in a system and relies on human opinion.

a) QoS
b) QUALINET
c) PDU
d) QoE

4.-The virtual machine approach is a common way for businesses and individuals to deal with legacy applications and to optimize their hardware usage by maximizing the various kinds of applications that a single computer can handle.
True OR False

5.-In the control plane, the ________ determines what user traffic may enter the network.
a) Admission control
b) QoS routing
c) Packet marking
d) Service level agreement

6.-A(n) ________ is incurred when a business spends money either to buy fixed assets or to add to the value of an existing asset with a useful life that extends beyond the tax year.

a) DevOps
b) Type 2 hypervisor
c) CapEx
d) OpEx

7.-A(n) ________ typically represents the agreement between a customer and a provider of a service that specifies the level of availability, serviceability, performance, operation, or other attributes of the service.

a) Policy
b) SLA
c) Queue management
d) Resource reservation

Answer 1

SOLUTION:-

ANSWER-(1):- c) NFVI

EXPLANATION:- NFVI includes 3 domains Hypervisor domain(Virtual Computing, Virtual Storage, Virtualization Layer), Compute Domain(Computing Hardware, Storage Hardware) and Infrastructure Network Domain(Virtual Network, Network Hardware)

ANSWER-(2):- c) Virtualization

EXPLANATION:- Virtualization includes a variety of technologies for managing computer resources by providing an abstraction layer( i.e., a software translation layer) between the software and the physical hardware​​​​​​​. Virtualization rotates physical resources into logical or virtual resources. By utilizing virtualization, users becomes potentially viable for management and utilization of resources without requiring the familiarity of physical information of resources.

ANSWER-(3):- d) QoE​​​​​​​

EXPLANATION:- QoE is a subjective measure of performance in a system and relies on human opinion and it is different from quality of service (QoS), which can be accurately computed, although QoE (Quality of Experience) is subjective and can not be numerically computed.

ANSWER-(4):- TRUE

EXPLANATION:- To keep sustain conferring the services provided via legacy systems, we can execute it as a virtual machine on new, modern hardware, while the legacy system itself still conduct as if it were running on the identical legacy hardware. In respect of application, nothing has altered. really, its performance will be benefited through the newly cardinal hardware via optimization of hardware utilization.
