Demo Questions
Question 1
Which of the following management tools performs the function of virtual infrastructure manager (VIM) in the CPC NFV architecture?
- NetAct
- CloudBand Infrastructure Software (CBIS)
- Operations Support System (OSS)
- Network Service Platform (NSP)
Correct answer: B
Question 2
Which of the following statements about the network service platform (NSP) is FALSE?
- Acts as an element management system (EMS) for CPC components
- Performs fault, performance, and security management
- Has a northbound interface with the NFV orchestrator (NFVO)
- Allows monitoring events associated with the NFV environment
Correct answer: C
Question 3
Which of the following network elements is implemented by the Nokia CPC?
- Policy and charging rules function (PCRF)
- Equipment Identity Registration (EIR)
- Application Function (AF)
- eNodeB
Correct answer: A
Question 4
What is the main benefit of splitting the core network into separate user-plane and control-plane nodes?
- Independent configuration of user-plane and control-plane nodes
- Independent scaling of user-plane and control-plane nodes
- User of a shared data repository for storing user states.
- Creation of networks with isolated properties over a common infrastructure
Correct answer: B
Question 5
Which of the following statements about SR-IOV is FALSE?
- VMs using OVS and SR-IOV can be instantiated on the same compute node.
- SR-IOV offers comparable performance to non-visualized hardware.
- The VM must be attached to the PF to achieve highest performance.
- Using SR-IOV restricts VM mobility.
Correct answer: D
Question 6
Which of the following best describes the reason for CPU pinning?
- To ensure that a VM is assigned to high performance CPU cores.
- To ensure that a VM's CPU cores area all allocated on the same NUMA node.
- To ensure that a VM is assigned to a compute node with adequate resources.
- To ensure that a VM is assigned a sufficient number of CPU cores.
Correct answer: A
Question 7
Which of the following describes the benefit of using huge pages?
- Huge pages improves the performance of mapping virtual memory addresses to physical memory addresses.
- Huge pages improves the performance of decreasing the number of memory accesses involved in a page table walk.
- Huge pages improves the performance of page swapping by increasing the number of TLB cache hits.
- Huge pages improves the performance of page swapping by optimizing the loading of pages to main memory.
Correct answer: C
Question 8
Which of the following describes the 2N model for VM redundancy?
- There is one active VM and one standby VM that takes over if the active VM fails.
- Thera are N active VMs and a pool of standby VMs that can take over if one or more active VMs fail.
- There are N active VMs, each one paired with a standby VM that takes over if its active VM fails.
- There are 2N active VMs deployed to support a service that needs N active VMs, with extra capacity in case one or more VMs fail.
Correct answer: C
Question 9
Which of the following statements about interface redundancy with OVS is FALSE?
- OVS provides redundancy through a Linux bonded interface on the hypervisor.
- Guest VMs have two virtual NICs connected to OVS through a Linux bridge.
- Ethernet frames are sent between the redundant interfaces to verify connectivity.
- OVS connects to two physical ports connected to distinct leaf switches.
Correct answer: C
Question 10
Which of the following OpenStack projects provides networking services to VMs?
- Neutron
- Nova
- Keystone
- Horizon
Correct answer: A
