   How can you verify that per-flow load balancing is working on a Junos device?

   • AUse 'show log messages' to see load-balancing events
   • BUse 'show interfaces statistics' to see the load on each interface
   • CUse 'show route protocol ospf' to see the OSPF neighbors
   • DUse 'show route forwarding-table' to see the hash-based next-hop selection

   A service provider has two equal-cost paths between two routers. They are using per-flow load balancing. The network team notices that one link is consistently more utilized than the other. They suspect that the hash algorithm is not distributing flows evenly. Which action would most effectively improve the distribution of flows across the two links?

   • AChange the load-balancing mode to per-packet.
   • BModify the hash key to include additional fields such as source and destination ports.
   • CIncrease the metric on the less utilized link to make it less preferred.
   • DUse a static route with a lower preference for the less utilized link.

   A network engineer has configured per-flow load balancing on a Junos router. After verifying with 'show route', they see two next-hops for a destination prefix. However, they notice that all traffic is going to only one next-hop. Which configuration issue is the most likely cause?

   • AThe two routes have different metrics.
   • BThe 'show route' command is not the correct verification command.
   • CThe 'load-balance per-flow' statement was placed under 'interfaces' instead of 'routing-options'.
   • DThe router is using per-packet load balancing by default.

   How does per-packet load balancing distribute traffic across equal-cost paths?

   • AIt alternates each packet across available paths
   • BIt uses the path with the lowest latency
   • CIt selects a path based on the destination IP address
   • DIt sends all packets of a flow over the same path

   A service provider is planning to deploy load balancing across their core. They have a mix of long-lived TCP flows and many short-lived UDP flows. Which statement accurately describes a benefit of load balancing in this environment?

   • ALoad balancing reduces the need for routing protocol convergence.
   • BLoad balancing improves network resilience by providing path redundancy.
   • CLoad balancing ensures all traffic uses the path with the lowest latency.
   • DLoad balancing increases the total available bandwidth for a single flow.
