   What is the primary purpose of a link aggregation group (LAG) on a Junos device?

   • ATo provide a backup path that is used only when the primary link fails
   • BTo enable routing protocols to exchange information over a single physical link
   • CTo combine multiple physical links into a single logical link, increasing bandwidth and providing redundancy
   • DTo segment a single physical link into multiple virtual LANs

   A company has two switches connected by two 10 Gbps links. They want to provide redundancy so that if the primary link fails, traffic automatically moves to the backup link. They do not need to combine the bandwidth. Which Junos feature should they configure?

   • AA static route with a lower metric for the primary link.
   • BA link aggregation group with both links as members.
   • CA redundant trunk group with one link designated as primary and the other as backup.
   • DA spanning tree protocol configuration to block one link.

   A network administrator is monitoring a LAG with three member links. They observe that the traffic distribution is uneven: one link carries 50% of the traffic, while the other two carry 25% each. The traffic consists of many small flows between many different hosts. What is the most likely cause of this uneven distribution?

   • AThe member links are of different speeds, and the switch is using the fastest link more often.
   • BThe hash algorithm is producing a limited number of hash results, causing some links to be selected more often.
   • CThe LACP mode is set to passive, which limits load balancing.
   • DOne of the member links is physically faulty and is being bypassed.
