Question 41
Which tool allows network administrators to automate network management and uses playbooks to define tasks?
a) Ansible
b) Chef
c) Puppet
d) OpenDaylight (ODL)
Correct Answer: a) Ansible
Explanation: Ansible is a network automation tool that uses playbooks written in YAML to define tasks, simplifying network configuration and management.
Question 42
Which SDN plane is responsible for managing communication between controllers and forwarding devices?
a) Control plane
b) Data plane
c) Application plane
d) Management plane
Correct Answer: a) Control plane
Explanation: The control plane manages communication between SDN controllers and forwarding devices like switches, making decisions about how traffic should be handled.
Question 43
Which SDN controller is widely deployed in the industry and is known for its modular design?
a) OpenDaylight (ODL)
b) NOX
c) Floodlight
d) Beacon
Correct Answer: a) OpenDaylight (ODL)
Explanation: OpenDaylight (ODL) is a widely deployed open-source SDN controller with a modular design, making it adaptable to various network environments.
Question 44
Which SDN security mechanism helps contain threats by segmenting the network into different security domains?
a) Security domains
b) Automated recovery
c) Dynamic device association
d) Replication
Correct Answer: a) Security domains
Explanation: Security domains help contain threats by segmenting the network into different levels of trust, isolating threats to only the affected sections of the network.
Question 45
Which OpenStack module is responsible for managing bare-metal compute capabilities instead of virtual machines?
a) Ironic
b) Glance
c) Nova
d) Swift
Correct Answer: a) Ironic
Explanation: Ironic is the OpenStack module responsible for provisioning and managing bare-metal compute capabilities, allowing users to manage physical hardware resources.
Question 46
Which OpenStack service provides key management for securing sensitive information like encryption keys and digital certificates?
a) Barbican
b) Trove
c) Horizon
d) Cinder
Correct Answer: a) Barbican
Explanation: Barbican is OpenStack’s key management service, designed to securely store and manage sensitive information such as encryption keys and digital certificates.
Question 47
Which SDN API allows external applications to interact with the SDN controller and request network services?
a) Northbound API
b) Southbound API
c) East/Westbound API
d) Data plane
Correct Answer: a) Northbound API
Explanation: The northbound API allows external applications to interact with the SDN controller, enabling applications to request network services and influence traffic behavior.
Question 48
Which SDN security mechanism involves creating multiple copies of network components to maintain service availability during an attack?
a) Redundancy
b) Controller diversity
c) Dynamic device association
d) Replication
Correct Answer: a) Redundancy
Explanation: Redundancy involves creating multiple copies of network components to maintain service availability during an attack or failure, ensuring continued operation.
Question 49
Which OpenStack module provides multi-tenant cloud messaging services, enabling communication between distributed components?
a) Zaqar
b) Glance
c) Trove
d) Ironic
Correct Answer: a) Zaqar
Explanation: Zaqar is OpenStack’s cloud messaging service, enabling multi-tenant communication between distributed components and services within a cloud environment.
Question 50
Which SDN mechanism improves security by limiting the attack surface through fine-grained control of data flows?
a) Fine-grained data flow and policy management
b) Controller-Switch trust
c) Dynamic device association
d) Automated recovery
Correct Answer: a) Fine-grained data flow and policy management
Explanation: Fine-grained data flow and policy management reduces the attack surface by allowing precise control over data flows and implementing detailed traffic policies.
