The video tutorial covers various network security techniques, including SNMP versions, IPv6 router advertisement protection, port security, dynamic ARP inspection, control plane security, port isolation, network access control, role-based access, ACLs, firmware updates, and firewall rules. It emphasizes the importance of using SNMP version 3 for encrypted communication, protecting IPv6 router advertisements with RA guard, and implementing port security to prevent unauthorized access. The tutorial also discusses the significance of role-based access, ACLs, and regular firmware updates to maintain network security.

Which version of SNMP should be used for secure communication?

• SNMP version 4

• SNMP version 1

• SNMP version 2

• SNMP version 3

What is the purpose of RA Guard in network security?

• To protect IPv6 router advertisements

• To manage VLAN configurations

• To monitor DHCP traffic

• To encrypt SNMP traffic

How does port security enhance network protection?

• By encrypting all network traffic

• By filtering ARP requests

• By disabling unused interfaces

• By limiting the number of MAC addresses on a port

What is the primary function of Dynamic ARP Inspection (DAI)?

• To manage SNMP configurations

• To isolate network ports

• To encrypt data plane traffic

• To prevent ARP spoofing

Why is it important to secure the control plane of a network device?

• To monitor DHCP traffic

• To manage VLAN configurations

• To encrypt all data traffic

• To prevent unauthorized access to management functions

What does port isolation achieve in a network?

• It manages SNMP configurations

• It prevents communication between devices on the same network

• It encrypts all network traffic

• It allows all devices to communicate freely

What is a key benefit of role-based access control in network management?

• It restricts access based on user roles

• It allows all users to have administrative access

• It manages VLAN configurations

• It encrypts all network traffic

Why is it important to regularly update firmware on network devices?

• To improve device aesthetics

• To ensure compatibility with older devices

• To patch security vulnerabilities

• To increase network speed

What is the purpose of an access control list (ACL) in network security?

• To allow all traffic through the network

• To manage SNMP configurations

• To encrypt all network traffic

• To restrict access based on predefined rules

What is the role of a firewall rule in network security?

• To encrypt all network traffic

• To monitor DHCP traffic

• To manage VLAN configurations

• To allow or disallow traffic based on specific criteria
