d415 Software Defined Networking - Set 4 - Part 1

Correct Answer: OpenDaylight (ODL)

OpenDaylight is an open-source SDN controller designed with modular, multi-protocol support, making it a popular choice for SDN deployments.

Correct Answer: Ironic

Ironic is the OpenStack module that allows users to provision bare-metal (physical) machines instead of virtual machines, giving users more control over hardware resources.

Correct Answer: Shuffling

Shuffling dynamically rearranges system configurations, such as IP addresses or routing paths, making it more difficult for attackers to exploit vulnerabilities.

Correct Answer: Trove

Trove is the OpenStack module that provides database-as-a-service (DBaaS) functionality, enabling users to deploy and manage relational and non-relational databases.

Correct Answer: Data plane

The data plane is responsible for forwarding data within the network, following the instructions provided by the control plane.

Correct Answer: Swift

Swift is the OpenStack service for object storage, designed to store and retrieve large amounts of unstructured data such as media files or backups.

Correct Answer: Northbound API

The northbound API enables external applications to communicate with the SDN control plane, allowing applications to request network services and influence network behavior.

Correct Answer: Horizon

Horizon is the OpenStack module that provides a graphical user interface (GUI) for managing OpenStack services such as compute, storage, and network resources.

Correct Answer: Replication

Replication involves creating replicas of key network components, ensuring that services remain available even if some components are compromised during an attack.

Correct Answer: Glance

Glance is the OpenStack module responsible for managing virtual machine images, allowing users to create and maintain images across the compute cluster.

Correct Answer: Fine-grained data flow and policy management

Fine-grained data flow and policy management reduces the attack surface by implementing strict controls on how data flows through the network, minimizing vulnerabilities.

Correct Answer: Keystone

Keystone is the OpenStack module that handles user authentication and provides access control, allowing users to access OpenStack services securely.

Correct Answer: Beacon

Beacon is an SDN controller known for its high-performance, multi-threaded architecture, making it suitable for cross-platform network deployments.

Correct Answer: Neutron

Neutron provides networking services in OpenStack, allowing virtual machines to communicate with each other and other resources in the cloud infrastructure.

Correct Answer: Southbound API

The southbound API allows the SDN controller to communicate with network devices like switches and routers, instructing them on how to forward traffic.

Correct Answer: Cinder

Cinder is the OpenStack service that provides block storage, allowing virtual machines to store data persistently, even after they are powered off or restarted.

Correct Answer: Controller-Switch trust

Controller-Switch trust ensures that the communication between SDN controllers and switches is secure, preventing unauthorized flows from being inserted by attackers.

Correct Answer: Zaqar

Zaqar is the OpenStack module that provides cloud messaging services, enabling multi-tenant communication between distributed components in a scalable cloud environment.

Correct Answer: Dynamic device association

Dynamic device association ensures that network devices are connected to the correct controllers, improving load balancing and fault tolerance in SDN environments.

Correct Answer: Barbican

Barbican is the OpenStack service responsible for securely storing and managing encryption keys, certificates, and other sensitive data within the cloud environment.
