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 a PIM SM multicast configuration, if the flows are still using only one path after implementing PIM join load balancing and committing the configuration, the correct solution is to use the 'clear pim join-distribution' command. This command redistributes the existing flows to new or restored upstream neighbors, effectively enabling the load balancing you configured.
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?
When both a behavior aggregate (BA) classifier and a multifield (MF) classifier are configured on a Junos device, and there is a conflict between their classifications, the MF classifier takes precedence. In this scenario, even though the BA classifier classifies the packet as best effort, the MF classifier classifies it as expedited forwarding. Since the classifications conflict, the packet will be placed in the queue associated with the MF classifier.
You must ensure that all management traffic sourced from your Junos devices is set with a specific DSCP code-point value.
Which action will accomplish this task?
To ensure that all management traffic sourced from Junos devices is set with a specific DSCP code-point value, you need to apply the DSCP code-point to the [edit class-of-service host-outbound-traffic] hierarchy. This is because the host-outbound-traffic configuration specifically addresses traffic that originates from the device itself, including management traffic, and allows you to set DSCP values appropriately.

A router is attempting to form an OSPF neighborship with another router. However, the OSPF neighborship fails to establish completely.
Referring to the exhibit, what is the problem?
The problem is that there is an interface type mismatch. This can be inferred from the log message 'OSPF packet ignored: configuration mismatch from 192.168.0.2 on intf ge-0/0/2.0 area 0.0.0.1,' which typically indicates a mismatch in interface configurations, such as one side being set to broadcast mode and the other to point-to-point mode.
You are currently using VLAN IDs 2 through 300 within your Layer 2 domain and you need to configure VSTP to prevent loops. You must ensure that all VLANs are loop free.
In this scenario, which statement is correct?
To ensure that all VLANs are loop-free when using VSTP (VLAN Spanning Tree Protocol), you must configure VSTP to include all VLANs within the specified range. This will ensure that spanning tree calculations are performed for each VLAN individually, thus preventing loops across all VLANs. Therefore, you need to enable all VLANs, 2 through 300, under the VSTP configuration.
