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
In Class 2 addressing, what is used to enable communication between LANs?
Direct node communication
Gateways with unique addresses
Mesh network connections
Multicast groups
What is the primary address type used in Class 3 IoT networks?
LL addresses
GUA
ULA
Broadcast addresses
Which of the following describes Class 4 addressing?
Proxy handles all communication and address management.
Gateway enables both local and global communication.
Nodes use LL addresses within a LAN.
Nodes are assigned unique global addresses.
What is the key difference between Class 4 and Class 5 addressing?
Class 5 uses a star topology.
Class 5 does not support GUA.
Class 5 uses mesh configuration.
Class 5 uses LL addresses for communication.
Which configuration enables point-to-point communication with unique global addresses?
Class 1
Class 3
Class 6
Class 7
What is the main advantage of Class 7 addressing?
Multiple gateways ensure redundancy.
Star topology reduces complexity.
Nodes communicate without gateways.
Address management is handled by proxies.
What determines the IoT addressing strategy?
The physical size of the network
Application and deployment location
The number of connected devices
Type of gateway used
What is the role of an IoT proxy in Class 3 addressing?
Connecting LANs to the Internet
Address allocation and management
Assigning LL addresses to nodes
Reducing latency in communication
In Class 4 addressing, what allows IoT nodes to communicate locally without routing through the Internet?
GUA assigned by the gateway
LL addresses for all nodes
Star topology configuration
Subnet prefix in the IPv6 address
Which class is most suitable for organizational IoT deployments requiring high reliability?
Class 1
Class 5
Class 6
Class 7
