Question #6 (Topic: Topic 1)
You have PIM SM multicast configured and running in a network environment comprised of EX4300 devices. Your customers report increased delay when
switching channels using IPTV. To help decrease the delay, you implement PIM join load balancing. You add the set protocols pim join-load-balance
command to the configuration. After committing, you notice that the flows are still using only one path.
In this scenario, which statement is correct?

In this scenario, which statement is correct?
A. The clear pim join-distribution command must be issued.
B. The interfaces must be specified to use for load balancing.
C. IGMP snooping must also be configured.
D. PIM join load-balancing only works for PIM-DM.
Answer: A
Question #7 (Topic: Topic 1)
You have configured CoS on a Junos device. A packet is classified as best effort by a behavior aggregate (BA) classifier, and as expedited forwarding by a
multifield (MF) classifier.
Which statement is true in this scenario?
multifield (MF) classifier.
Which statement is true in this scenario?
A. The packet will be placed in a queue associated with the BA classifier.
B. The packet will be placed into the queue which is least congested.
C. The packet will be placed into the queue that has the most bandwidth assigned to it.
D. The packet will be placed in a queue associated with the MF classifier.
Answer: A
