What is SDN?

• Software Data Node

• Software Defined Networking

• Software Data Networking

• Software Defined Node

Which of the following are true about SDN Controller? (Choose Two Best Answers)

• Manages flow control to the switches/routers ‘below’ (via southbound APIs)

• OpenFlow is used to communicate with the networking devices via southbound APIs

• Manages applications and business logic ‘above’ (via northbound APIs) to deploy intelligent networks

• It is used to collect information about networking devices using SNMP

What are the 3 layers that make up SDN Architecture?

• 1) Application layer, 2) Control layer, and 3) Infrastructure layer

• 1) Data layer, 2) Transport layer, and 3) Infrastructure layer

• 1) Application layer, 2) Presentation layer, and 3) The physical layer

• 1) Application layer, 2) Session layer, and 3) Presentation layer

Which of the following is NOT an advantage of SDN?

• Network is programmable hence can easily be modified via the controller rather than individual switches

• Switch hardware becomes cheaper since each switch only needs a data plane

• The central dependency of the network means single point of failure, i.e. if the controller gets corrupted, the entire network will be affected.

• Provides better security since the controller can monitor traffic and deploy security policies

In SDN, ________ consists of physical switches which forms the data plane and carries out actual movement of data packets

• Session Layer

• Infrastructure Layer

• Control Layer

• Application Layer

__________include anything specifically designed to prevent attacks on data, including DDoS mitigation, and intrusion prevention systems.

• Physical security controls

• Digital security controls

• Cyber security controls

• Cloud security controls

You are asked to implement a system that will require individuals to present a password and enter a PIN at the security gate before gaining access to avoid unauthorized access. What is this type of system called?

• Authorization

• Authentication

• Management

• Two Factor Authorization

Which one of the following is NOT a factor in IAM Framework

• Authentication

• Authorization

• User Management

• Auditing

Which one of the following is NOT a key benefit of IAM?
