Which of the following is true about the core layer?
a. Data congestion in the core doesn't need to be avoided.
b. It's the backbone of the network.
c. Only minor portions of data travel in the core.
d. Route policies are often enforced at this layer.
b. It's the backbone of the network.
Explanation: The core is the heart or the backbone of the network. The major portion of a network's data traffic passes through the core. Data congestion should be avoided at the core if possible. This means that unnecessary route policies should be avoided leaving all core network device resources available for high-speed traffic forwarding.
