Question 41
Which OpenStack service provides a GUI for managing OpenStack resources, including compute, storage, and networking?
a) Horizon
b) Glance
c) Swift
d) Neutron
Correct Answer: a) Horizon
Explanation: Horizon provides a graphical user interface (GUI) for managing OpenStack resources, making it easier for users to interact with compute, storage, and networking services.
Question 42
Which SDN security mechanism helps prevent unauthorized traffic from moving through the network by applying strict policies?
a) Fine-grained data flow management
b) Controller-Switch trust
c) Shuffling
d) Replication
Correct Answer: a) Fine-grained data flow management
Explanation: Fine-grained data flow management applies strict policies to control how data flows through the network, preventing unauthorized traffic and enhancing network security.
Question 43
Which OpenStack service provides database management capabilities, allowing users to deploy and manage databases on demand?
a) Trove
b) Swift
c) Glance
d) Neutron
Correct Answer: a) Trove
Explanation: Trove provides database-as-a-service capabilities, allowing users to deploy and manage relational and non-relational databases on demand in the cloud.
Question 44
Which SDN mechanism prevents attackers from predicting network behavior by dynamically rearranging network configurations?
a) Shuffling
b) Controller-Switch trust
c) Replication
d) Dynamic device association
Correct Answer: a) Shuffling
Explanation: Shuffling dynamically rearranges network configurations, making it more difficult for attackers to predict network behavior, reducing the effectiveness of attacks.
Question 45
Which OpenStack service allows users to manage and store virtual machine images for deployment in the cloud?
a) Glance
b) Swift
c) Cinder
d) Horizon
Correct Answer: a) Glance
Explanation: Glance is the OpenStack service that allows users to manage and store virtual machine images, enabling the deployment of VMs in the cloud environment.
Question 46
Which SDN mechanism helps secure communication between controllers and network devices by preventing unauthorized data flows?
a) Controller-Switch trust
b) Shuffling
c) Replication
d) Fine-grained data flow management
Correct Answer: a) Controller-Switch trust
Explanation: Controller-Switch trust ensures secure communication between controllers and network devices, preventing unauthorized data flows from entering the network.
Question 47
Which OpenStack service provides big data processing capabilities, enabling users to manage Hadoop clusters and other big data frameworks?
a) Sahara
b) Trove
c) Neutron
d) Glance
Correct Answer: a) Sahara
Explanation: Sahara provides big data processing capabilities, allowing users to manage Hadoop clusters and other big data frameworks for scalable data processing in the cloud.
Question 48
Which SDN API enables external applications to communicate 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 enables external applications to communicate with the SDN controller, allowing them to request network services and manipulate network behavior in real time.
Question 49
Which OpenStack service provides shared file system management, enabling virtual machines to access shared storage across compute instances?
a) Manila
b) Swift
c) Cinder
d) Neutron
Correct Answer: a) Manila
Explanation: Manila is the OpenStack service responsible for managing shared file systems, allowing virtual machines to access shared storage across multiple compute instances.
Question 50
Which SDN mechanism allows the network to dynamically recover from attacks by rearranging network configurations and paths?
a) Shuffling
b) Dynamic device association
c) Replication
d) Fine-grained data flow management
Correct Answer: a) Shuffling
Explanation: Shuffling rearranges network configurations and paths in response to attacks, helping to protect the network from further exploitation and improving network resilience.
