Which deployment model isolates virtual functions in NFV?
ASingle Tenant Model
BMulti-Tenant Model
CHybrid Model
DFallback Model
Explanation
The Multi-Tenant Model allows for isolated resource environments for different tenants, ensuring security and performance. Single Tenant shares resources too broadly, Hybrid mixes too many properties unfavorably, and Fallback isn't a recognized model.
Q32
A company needs to ensure high availability for its NFV environment. What should they implement?
ALoad Balancing
BManual Scaling
CSingle Point of Failure
DMono-Architecture
Explanation
Implementing Load Balancing distributes demand, enhancing availability. Manual Scaling is unreliable, Single Point of Failure compromises reliability, and Mono-Architecture lacks redundancy.
Q33
What happens when a VNF exceeds its resource allocation during peak usage?
AIt automatically scales down
BPerformance may degrade
CIt operates at full capacity
DIt receives additional resources automatically
Explanation
When a VNF exceeds its resource allocation, performance may degrade due to resource contention. It cannot scale down or gain more resources automatically without configured policies, and will not run at full capacity without sufficient resources.
Q34
Which service facilitates the orchestration of network functions in VMware Telco Cloud?
AVMware NSX-T
BvRealize Automation
CvCloud Director
DVMware Horizon
Explanation
VMware NSX-T specializes in network functions orchestration, while others focus on different aspects of cloud management.
Q35
A company needs to ensure their NFV deployment can scale based on demand. What should they primarily leverage?
AStrict hardware provisioning
BAuto-scaling policies
CManual adjustments
DSet resource limits
Explanation
Auto-scaling policies allow dynamic resource adjustments based on load, unlike the other options that rely on static management.
Q36
You are configuring a VNF in VMware Telco Cloud. What happens when you enable high availability?
AIncreased latency
BGuaranteed uptime during failure
CLower resource usage
DReduced bandwidth needs
Explanation
Enabling high availability ensures continuous service during failures, unlike the other options which incorrectly define effects of HA.
Q37
Which service is crucial for virtual network slicing in NFV?
ANetwork Functions Virtualization Orchestrator
BStorage Area Network
CVirtual Machine Manager
DBackup and Recovery Service
Explanation
Network Functions Virtualization Orchestrator manages network slicing; others are unrelated to slicing management.
Q38
A company needs to ensure high availability for its NFV infrastructure; which design principle should they prioritize?
ASingle point of failure
BActive-active configuration
CDirect storage access
DCentralized management
Explanation
Active-active configuration ensures redundancy and high availability; others compromise resilience.
Q39
What happens when a VM runs out of CPU resources in an NFV environment?
AIt automatically shuts down
BIt experiences degradation in performance
CIt generates a memory dump error
DIt reverts to a previous snapshot
Explanation
Performance degradation occurs due to resource starvation; others describe incorrect failure behaviors.
Q40
Which service provides automated VNFs deployment?
AvCloud Director
BCloud Director Services
CvRealize Automation
DvSphere Replication
Explanation
vRealize Automation automates the deployment of VNFs; other options do not.
