Question 22

Click the Exhibit button.

You want to use both links between R1 and R2. Because of the bandwidth difference between the two links, you must ensure that the links are used as much as possible.

Which action will accomplish this goal?

Ensure that the metric-out parameter on the Gigabit Ethernet interface is higher than the 10 Gigibit Ethernet interface.

Define a policy to tag routes with the appropriate bandwidth community.

Enable per-prefix load balancing.

Disable multipath.

Correct Answer: B

To use both links between R1 and R2 effectively considering the bandwidth difference, the best approach is to define a policy to tag routes with the appropriate bandwidth community. This ensures that traffic is allocated in proportion to each link's bandwidth, allowing for efficient utilization of both links. The other options do not address the need to consider bandwidth differences in load balancing.

Bob_SmithOption: B

B makes the most sense. Juniper can advertise a bandwidth community that will load balance flows proportionally based on bandwidth values

eknowOption: B

C is not correct. you should use per-packet instead of per-prefix.

easynet13Option: B

B is correct.
