Enterprise Network Security
Mock Exam
Course Introduction
Enterprise Network Security is a comprehensive course that explores the principles, architectures, and practical approaches to securing large-scale corporate networks. Students will learn about risk assessment, threat modeling, and the deployment of robust security measures, including firewalls, intrusion detection and prevention systems, secure network design, and virtual private networks (VPNs). The course covers best practices for identity and access management, network segmentation, and incident response, with an emphasis on current challenges posed by cloud integration and remote access. Through case studies and hands-on labs, students will develop the analytical skills and technical expertise necessary to safeguard complex enterprise environments against evolving cyber threats.

Sample Questions
Q1) What is a MAC address?
Answer: The MAC address is a hardware address that uniquely identifies each node of a network. Other names for the MAC address are vendor address, vendor ID, NIC address, Ethernet address, and physical address.
The MAC address is a unique 48-bit number that is "burned" into the network interface adapter when it is manufactured. This number consists of two parts: a 24-bit organizationally unique identifier (OUI), sometimes called a "company ID," which references the company that produced the adapter, and a 24-bit individual address block (IAB), which uniquely identifies the card itself.
Q2) A wireless device is set to look for beacon frames from the AP. This is known as ____________________.
Answer: scanning
Q3) ____ traffic is traffic sent to all users on the network.
A) Unicast
B) Broadcast
