   A network administrator is troubleshooting a LAG with two member links. They notice that all traffic from a single server to multiple clients is going over only one link. The server has a single MAC address and a single IP address. What can the administrator do to improve load balancing for this traffic pattern?

   • AAdd more member links to the LAG.
   • BChange the LAG hash algorithm to include Layer 4 port information.
   • CChange the LACP mode from active to passive.
   • DIncrease the LACP transmission interval to fast.

   How does a Junos device distribute traffic across member links in a link aggregation group?

   • AIt round-robins packets across all member links in sequence
   • BIt uses a hash algorithm based on packet fields to select a member link for each flow
   • CIt sends all traffic on the first member link until it is full, then uses the next
   • DIt sends traffic on the member link with the lowest current utilization

   What is the primary role of the Link Aggregation Control Protocol (LACP) in a link aggregation group?

   • ATo select the active link in a redundant trunk group
   • BTo provide encryption for traffic traversing the aggregated link
   • CTo load-balance traffic across the member links using a hash algorithm
   • DTo negotiate and maintain the LAG by exchanging LACPDUs between the peers

   A switch has a redundant trunk group with ge-0/0/0 as primary and ge-0/0/1 as backup. The primary link fails. What happens to the traffic on the switch?

   • ATraffic is immediately moved to the backup link with minimal interruption.
   • BTraffic is dropped until the primary link is restored.
   • CTraffic is rerouted through the routing table to a different path.
   • DTraffic is load-balanced across both links.

   A data center has two switches connected by four 10 Gbps links. The traffic is primarily between a few application servers and many storage devices. The network team wants to maximize bandwidth utilization and ensure that a single link failure does not cause a significant traffic disruption. They are considering using a LAG. What is the primary consideration for achieving good load balancing in this scenario?

   • AConfigure the LAG with a higher number of member links to improve redundancy.
   • BUse a redundant trunk group instead of a LAG to ensure only one link is active.
   • CUse LACP in active mode on both switches to ensure the LAG forms quickly.
   • DEnsure the hash algorithm includes Layer 4 port information to differentiate flows from the few servers.
