Which of the following statements are correct regarding NETCONF? (Select 2 choices.)
- NETCONF is an opensource cloudcomputing platform.
- NETCONF is a connectionless protocol.
- NETCONF is a standardsbased protocol.
- NETCONF uses XML as the data modeling language.
- NETCONF uses YANG as the data modeling language.
Network Configuration Protocol (NETCONF) is a standardsbased protocol that uses YANG as the data modeling language. NETCONF, which is described in Request for Comments (RFC) 6241, provides the ability to automate the configuration of network devices. YANG, which is defined in RFC 6020, is a hierarchical data modeling language that can model configuration and state data for NETCONF.
NETCONF does not use Extensible Markup Language (XML) as the data modeling language? NETCONF uses XML as its data encoding method. YANG data that is used by NETCONF is encoded in an XML format.
NETCONF is not a connectionless protocol. Rather, it is a connectionoriented protocol that requires a persistent, reliable connection. NETCONF connections must also provide confidentiality, integrity, authentication, and replay protection. Secure Shell (SSH) is the mandatory transport protocol for NETCONF.
NETCONF is not an opensource cloudcomputing platform. 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
