   A company is designing a high-availability solution for its SRX firewalls. They need to provide redundancy for the entire device, including the control plane and all services, with active/passive failover. They also want to use SRG to manage specific services independently. Which deployment approach correctly combines chassis clustering and SRG?

   • AConfigure SRG on each node separately and use chassis clustering only for management plane redundancy.
   • BUse chassis clustering for device-level redundancy and configure SRG within the cluster to manage service-specific failover.
   • CDeploy chassis clustering and SRG as separate, independent solutions, each managing different services without interaction.
   • DUse SRG as a replacement for chassis clustering, as SRG provides full device-level redundancy.

   Which of the following is a required parameter when configuring a services redundancy group (SRG) on an SRX Series device?

   • AA virtual IP address for the group
   • BA unique SRG ID that identifies the group
   • CA routing protocol to be used for failover detection
   • DA dedicated management interface for the group

   An SRG is configured with session synchronization. The primary node is processing a high volume of traffic, and the backup node is receiving a constant stream of session updates. The network team is concerned about the performance impact of this synchronization on the primary node. Which statement accurately describes the performance impact?

   • ASession synchronization can consume CPU and control link bandwidth, but the impact is typically minimal and can be managed with proper configuration.
   • BSession synchronization will cause the primary node to drop traffic if the control link is congested.
   • CSession synchronization is only performed during failover, so it has no ongoing impact.
   • DSession synchronization has no impact on the primary node's performance because it is handled by dedicated hardware.

   An SRG is configured on two SRX devices to provide stateful firewall services. The primary node experiences a hardware failure and becomes unresponsive. The backup node detects the failure and takes over the active role. Which mechanism is used by the SRG to detect the failure and trigger failover?

   • AThe backup node uses the routing protocol to detect that the primary's routes have been withdrawn, indicating failure.
   • BThe backup node polls the primary node's management interface using ICMP to verify it is still alive.
   • CThe backup node waits for the primary node to send a 'failover' message before assuming the active role.
   • DThe backup node monitors the primary node's health via a dedicated control link and uses a hold-time timer to confirm the failure before taking over.

   How does a services redundancy group (SRG) monitor the health of the primary node to trigger failover?

   • ABy requiring an administrator to manually initiate failover
   • BBy monitoring the status of the physical interfaces and sending periodic keepalive messages between nodes
   • CBy relying on the routing protocol to detect a node failure
   • DBy checking the CPU and memory utilization of the primary node every second
