CCNA Security Final Exam v1.2 – Questions and Answers

Are you preparing for the CCNA Security Final Exam v1.2? Look no further! In this blog post, we will cover a comprehensive list of questions and answers that will help you succeed on your exam.

Introduction to CCNA Security

CCNA Security is a certification program designed to validate the knowledge and skills required to secure Cisco networks. It covers various topics including network security concepts, secure access, VPN encryption, firewalls, intrusion prevention, and more.

CCNA Security Final Exam v1.2 – Questions

1. What is network security?

Network security refers to the practice of securing a network infrastructure and ensuring the confidentiality, integrity, and availability of data and resources.

2. Explain the concept of AAA.

AAA stands for Authentication, Authorization, and Accounting. It is a security framework used to control access to network resources. Authentication verifies the identity of users, authorization determines what actions they are allowed to perform, and accounting tracks the usage of network resources.

3. What are the different types of firewalls?

There are three main types of firewalls: packet-filtering firewalls, stateful inspection firewalls, and next-generation firewalls. Packet-filtering firewalls examine network packets based on predefined rules, stateful inspection firewalls keep track of the state of network connections, and next-generation firewalls combine multiple security features such as intrusion prevention, malware detection, and application awareness.

4. How does VPN encryption work?

VPN encryption uses cryptographic protocols to create a secure tunnel between two endpoints. It encrypts the data packets sent over the network, making them unreadable to anyone who intercepts them.

5. What is the purpose of an intrusion prevention system (IPS)?

An intrusion prevention system (IPS) is designed to monitor network traffic and detect and prevent malicious activities. It can identify and block suspicious traffic, protecting the network from potential attacks.
