What is the primary focus of IPv6 compared to IPv4?

• Reliable delivery of packets

• Address-oriented communication

• NAT translation

• Simplified routing algorithms

What is the length of an IPv6 address?

• 32 bits

• 64 bits

• 128 bits

• 256 bits

What is the main reason IPv6 is critical for IoT?

• Increased speed of communication

• Larger address space

• Improved packet reliability

• Simpler routing protocols

Which part of the IPv6 address is globally unique?

• Subnet prefix

• Interface Identifier (IID)

• Global prefix

• Link-local address

How is the Interface Identifier (IID) typically generated?

• Using DNS lookups

• Based on MAC addresses or pseudo-random algorithms

• Manually assigned by administrators

• Derived from the subnet prefix

Which of the following is not an IPv6 address type?

• Unicast

• Multicast

• Anycast

• Broadcast

What type of communication is facilitated by a multicast address?

• One-to-one

• One-to-many

• One-to-nearest

• Many-to-one

What is the purpose of anycast addressing?

• Broadcast to all nodes

• Communication with the nearest node in a group

• Point-to-point communication

• Assigning unique addresses to all nodes

What is the primary characteristic of Class 1 in IoT addressing?

• Isolated nodes communicating within a LAN

• Nodes connected to the Internet via a proxy

• Nodes using GUA for Internet connectivity

• Star topology configuration

What address type is primarily used in Class 1 IoT configurations?

• GUA

• ULA

• LL (Link-local)

• Proxy addresses
