In a threenode OpenStack architecture, which services are part of the compute node? (Select 2 choices.)

  • Ceilometer Agent
  • Ceilometer Core
  • Neutron DHCP Agent
  • Neutron Server
  • Nova Hypervisor
  • Nova Management
  • Correct
Explanation:
In a three-node OpenStack architecture, the Ceilometer Agent and the Nova Hypervisorservices are part of the compute node. OpenStack is an opensource cloudcomputing platform. Each OpenStack modular component is responsible for a particular function, and each component has a code name. The following list contains several of the most popular OpenStack components:

-Nova -OpenStack Compute: manages pools of computer resources
-Neutron -OpenStack Networking: manages networking and addressing
-Cinder -OpenStack Block Storage: manages blocklevel storage devices
-Glance -OpenStack Image: manages disk and server images
-Swift -OpenStack Object Storage: manages redundant storage systems
-Keystone -OpenStack Identity: is responsible for authentication
-Horizon -OpenStack Dashboard: provides a graphical user interface (GUI)
-Ceilometer -OpenStackTelemetry: provides counterbased tracking that can be used for customer usage billing

A threenode OpenStack architecture consists of the compute node, the controller node, and the network node. The compute node consists of the following services:

-Nova Hypervisor
-Kernelbased Virtual Machine (KVM) or Quick Emulator (QEMU)
-Neutron Modular Layer 2 (ML2) PlugIn
-Neutron Layer 2 Agent
-Ceilometer Agent
-The controller node consists of the following services:

-Keystone
-Glance
-Nova Management
-Neutron Server
-Neutron ML2 PlugIn
-Horizon
-Cinder
-Swift
-Ceilometer Core

The network node consists of several Neutron services:

-Neutron ML2 PlugIn
-Neutron Layer 2 Agent
-Neutron Layer 3 Agent
-Neutron Dynamic Host Configuration Protocol (DHCP) Agent
