Refer to the exhibit.
The exhibit shows a core network with four core routers (one per site). All core links are 10 Gigabit
Ethernet. The IGP cost metric is the same for all core links. Which two statements regarding this
network are correct? (Choose two.)
A.
There is sufficient core capacity to meet the demand for a single-node or single-link failure
scenario if y = 4 Gb/s in the demand table.
B.
A single-link failure would triple the utilization of some links in the core.
C.
A single-link failure would double the utilization of some links in the core.
D.
A single-link failure would cause saturation of one link in the core network if y = 3.5 Gb/s in the
demand table.
E.
A single-node failure would cause saturation of one link in the core network if y = 2 Gb/s in the
demand table.
