A company is deploying an SRX cluster at its headquarters. The network team has two conflicting goals: they want to maximize throughput by using both devices, but they also have a legacy application that breaks if traffic for a session arrives on different devices. The team is considering active/active with session synchronization. What is the primary risk of this approach?

Active/active mode does not support stateful firewall features.

Active/active mode requires a dedicated link for session synchronization, reducing available bandwidth.

Active/active can still cause asymmetric routing, which could break the legacy application.

Session synchronization will not work in active/active mode.

A network administrator is configuring an SRX cluster in active/passive mode. The administrator wants to ensure that if the active node fails, the passive node takes over with minimal disruption. What is the primary mechanism that enables this failover?

Cluster heartbeat and failover detection

A company is deploying a cluster of two SRX devices at a branch office. The branch has a single uplink and a single downstream switch, and the network team wants to minimize complexity and avoid any chance of asymmetric routing. They also need to ensure that if the active device fails, the backup device takes over with minimal disruption. Which deployment mode should they choose?

Active/active with session synchronization

Active/passive without failover

In a Junos OS chassis cluster, what is a key characteristic of the active/active deployment mode?

Both nodes forward traffic and share the load.

The cluster requires a dedicated management node to coordinate traffic.

Traffic is handled by a single node that changes based on the source IP address.

Only one node forwards traffic while the other remains idle.

A company is deploying an SRX cluster in active/active mode. The network team wants to ensure that if one node fails, the other node can continue to forward traffic for all existing sessions. However, the team is concerned about the overhead of session synchronization on the control link. What is the best approach to mitigate this concern?

Increase the data link bandwidth to compensate for synchronization overhead.

Use active/passive mode instead to avoid synchronization overhead.

Disable session synchronization to reduce overhead.

Use a dedicated high-bandwidth link for the control link to handle synchronization traffic.
