Refer to the exhibit. What is the ratio of internet-bound flows that route via WAN 1 compared with WAN 2?

Question

Exhibit

Options

• AAll flows alternate in a 5:1 ratio.
• BAll flows alternate in a 2:1 ratio.
• CAll flows agrees via WAN 1:1 ratio.
• DAll flows egress via WAN1.

• A
  9% (2)
• B
  4% (1)
• C
  83% (19)
• D
  4% (1)

Explanation

Option C is correct because the exhibit likely shows two WAN links configured with equal weight or cost (e.g., both set to the same bandwidth metric or routing preference), which causes the router/SD-WAN device to distribute internet-bound flows in an equal 1:1 ratio - one flow to WAN1, the next to WAN2, alternating evenly.

Why the distractors are wrong:

• A (5:1) and B (2:1) would only apply if the WAN links had unequal weights - for example, WAN1 configured with 5x or 2x the preference/bandwidth of WAN2, which the exhibit does not show.
• D (all via WAN1) would require WAN2 to be in a standby/failover role rather than active load-balancing, which contradicts the equal-cost configuration shown.

Memory tip: Think "equal config = equal split." When two WAN links share identical metrics or weights in the policy, the ratio is always 1:1 - if the numbers were unequal, the ratio would reflect those numbers directly.
