   Which characteristic is true of active/active mode in Junos HA?

   • AThe cluster requires a dedicated external load balancer to distribute traffic.
   • BOnly one node is active at a time, and the other is in standby.
   • CBoth nodes must be in the same geographic location to function.
   • DBoth nodes are active for different redundancy groups, allowing load sharing.

   What is a requirement for chassis clustering to support active/active mode?

   • AA separate out-of-band management network for each node.
   • BA dedicated control link between the nodes for heartbeat and synchronization.
   • CBoth nodes must have identical hardware models and software versions.
   • DAt least one interface on each node must be configured as a redundant Ethernet interface.

   What happens to existing sessions when a node fails in active/active mode?

   • AAll sessions are automatically preserved because the other node takes over.
   • BSessions are always lost because active/active mode does not support session preservation.
   • CSessions on the failed node are lost unless they are synchronized to the surviving node.
   • DSessions are preserved only if the failure is on the control plane.

   A service provider is deploying a chassis cluster of two SRX5800 devices in an active/active configuration to serve two distinct customer segments. Each segment must have its own dedicated set of interfaces and be actively forwarding traffic on its designated node. The cluster is already formed and both nodes are visible in the chassis cluster status. Which configuration step is required to achieve this active/active behavior?

   • ACreate a single redundancy group for all interfaces and use the 'redundancy-group' interface option to specify which node should handle each individual IP address.
   • BPlace all customer-facing interfaces in a single redundancy group and enable the 'active-active' option on the redundancy group configuration.
   • CConfigure the cluster to use the 'load-balance' mode in the chassis cluster configuration, which automatically distributes all interfaces between the two nodes.
   • DAssign the two customer segments' interfaces to different redundancy groups and set the redundancy group priority so that each node is primary for one group.

   A company has deployed an active/active chassis cluster. They have two redundancy groups: RG1 and RG2. They notice that the CPU utilization on Node 0 is consistently higher than on Node 1. What is the most likely reason for this imbalance?

   • ANode 1 is not receiving any traffic because its interfaces are not properly configured.
   • BThe control link is congested, causing Node 0 to process more control traffic.
   • CRG1, which is primary on Node 0, is handling a significantly larger volume of traffic than RG2.
   • DNode 0 is performing more session synchronization updates to Node 1 than vice versa.
