Nokia 4A0-M05 Nokia Cloud Packet Core Exam Practice Test

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.

The “openstack server list” command only lists active servers.

All the servers listed are created on the controller01 hypervisor.

All the servers listed are inter-connected via network “int0”.

The three necc servers are created in an anti-affinity server group.

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.

Core network may be EPC or next-generation core

There is a data plane interface between eNB and EPC

eNB has both control plane and data plane connections to the core

There is an X2 interface between eNB and gNB

Terminates external logical interfaces.

Manages UE registration and authentication.

Assigns new subscribers to internal CPPS and PAPS.

Implements network load/overload control.

Only the master CMG instance handles call processing and data path forwarding

1:1 geo-redundancy mode is used

Master CMG instance synchronizes subscriber information to its slave CMG instance

Slave CMG instance takes over when the master CMG instance is in overload state

Call processing services are deployed in active-standby mode and resources are fully duplicated

Call processing services are deployed in pure stateless mode and UE contexts are only stored in an external database

Call processing services are deployed in hybrid mode and UE contexts are stored both locally and in an external database

Call processing services are deployed in all-active mode and UE contexts are only stored locally

The CMM VNF consists of multiple virtual machines that run on top of a cloud infrastructure.

The load balancer layer terminates external logical interfaces.

The transaction layer processes 3G user plane.

The CMM VNF follows a multi-tier architecture where each tier can scale independently.
