A company is implementing a chassis cluster for high availability in transparent mode. The cluster will be placed between two switches. What is a critical consideration for the cluster interfaces?

Both nodes must have the same Layer 2 configuration, including VLAN assignments.

The cluster interfaces must be configured as Layer 3 with virtual IPs.

The cluster interfaces must be in different security zones.

Each node must have a different VLAN assignment to avoid conflicts.

Which statement accurately describes the role of a transparent mode device in a Layer 2 network?

It acts as a default gateway for hosts in the network.

It translates private IP addresses to public IP addresses for internet access.

It segments the network into separate broadcast domains.

It filters traffic based on Layer 2 and higher-layer criteria while remaining invisible to the network.

What is the purpose of the control link in a chassis cluster configured for transparent mode?

To synchronize configuration and session state between the nodes.

To connect the cluster to the management network.

To provide a backup path for hosts to reach the internet.

To forward data traffic between the two nodes.

An SRX in transparent mode is placed between two switches. The administrator notices that broadcast traffic is being flooded to all interfaces in the VLAN. What is the reason for this behavior?

The SRX is forwarding broadcast frames to all interfaces in the same VLAN, as expected in Layer 2 forwarding.

The SRX is configured with a security policy that allows broadcast traffic.

The SRX is misconfigured and should only forward broadcast frames to the interface where the broadcast originated.

The SRX is not learning MAC addresses and therefore floods all unknown unicast traffic.

What is a primary characteristic of transparent mode on a Juniper security device?

The device performs Network Address Translation (NAT) on all traffic passing through.

The device operates as a Layer 2 bridge, forwarding frames based on MAC addresses without routing.

The device requires VLAN tagging on all interfaces to function.

The device acts as a Layer 3 router, requiring IP addresses on each interface.

Part of the Layer 2 Security domain, which makes up ~14% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–8 in this domain), expect 1–2 from this objective — we provide 13 practice questions to prepare you well beyond it.
