What happens to a session in a Juniper security device when the session timeout is reached?

The session is marked as inactive but remains in the table.

The session is refreshed and the timeout is reset.

The session is moved to a quarantine list.

The session is removed from the session table.

A network engineer is troubleshooting a new security policy on a Juniper SRX Series device. The policy is configured to permit HTTP traffic from the trust zone to the untrust zone, but the traffic is being dropped. While reviewing the packet flow, the engineer notices that the session is not being created. At which stage of the packet processing pipeline is the session most likely failing to be established?

During the ingress interface's MAC address lookup, before any policy evaluation.

During the egress interface's ARP resolution, after the session has been created.

During the session setup stage, after the initial policy lookup and before the session is installed in the session table.

During the forwarding decision, after the session table has been updated.

A network administrator is configuring an SRX to handle a large number of short-lived UDP connections from a specific application. The administrator wants to ensure that the session table does not become full with stale sessions. What is the most effective configuration change to address this?

Decrease the UDP session timeout.

Disable the session table for UDP traffic.

Configure the SRX to use a stateless firewall filter for UDP traffic.

Increase the maximum session limit.

A security administrator is troubleshooting a problem where a specific application's traffic is being dropped on an SRX. The administrator has verified that the security policy permits the traffic and that the NAT rule is correctly configured. The administrator also notices that the traffic is being dropped during the session setup stage. What is the most likely cause?

The NAT rule is not matching the traffic.

An administrator is troubleshooting a performance issue on an SRX where legitimate traffic is being dropped. The administrator suspects that the session table is full. Which command would confirm this suspicion?
