Comprehensive and Detailed Explanation:

IPv6 supports several extension headers:✅ Fragment Extension Header → Handles packet fragmentation.✅ Destination Options Header → Stores information for destination nodes.✅ Hop-by-Hop Options Header → Used for router-specific instructions.

❌ Incorrect Option:

Private vs Public IPs:

192.168.1.2 belongs to the private IP range (192.168.0.0/16).

Private IP addresses cannot be routed on the Internet and must be translated.

Network Address Translation (NAT):

NAT converts private IP addresses to a public IP so that the device can access the Internet.

Conclusion:

NAT is required to access the Internet from a private IP, making the statement TRUE.

Comprehensive Explanation: Fit APs (Access Points) are designed to work in conjunction with an Access Controller (AC). They rely on the AC for configuration, management, and control of their wireless services. Without an AC, a Fit AP cannot function independently or provide wireless services. This is in contrast to Fat APs, which have their own management capabilities and can operate independently.

A floating static route is configured by assigning a higher preference value to the backup route. This ensures that the backup route (floating route) is used only when the primary route is unavailable. Lower preference values indicate higher priority​.
