What is the difference between interconnection and peering?
-
Interconnection is a physical connection between two networks, while peering is a logical connection
-
Interconnection is always paid, while peering is always free
-
Interconnection is governed by regulations, while peering is not
-
Interconnection is used for voice traffic, while peering is used for data traffic
A
Correct answer
Explanation
Interconnection involves the physical connection of two networks, while peering involves the logical connection of two networks at a common point, allowing them to exchange traffic.
How does interconnection relate to access to networks?
-
Interconnection is a necessary condition for access to networks
-
Access to networks is a necessary condition for interconnection
-
Interconnection and access to networks are independent of each other
-
None of the above
A
Correct answer
Explanation
Interconnection is a necessary condition for access to networks because it allows different networks to connect with each other, enabling users on one network to access services and content on another network.
