A security team is deploying a pair of SRX firewalls in a chassis cluster. They have two requirements: they want to maximize throughput by using both devices for traffic, and they need stateful failover for existing sessions. Which redundancy mode should they choose?

Active/active mode without session synchronization

Active/active mode with session synchronization

Active/passive mode with session synchronization

Active/passive mode without session synchronization

In a Virtual Chassis, what is the role of the backup Routing Engine (RE)?

To forward data plane traffic in parallel with the primary RE

To provide additional ports for the Virtual Chassis

To take over control plane functions if the primary RE fails

To manage the power supply of the Virtual Chassis

A large enterprise data center is expanding its fabric and needs to scale to hundreds of switches while maintaining a simple, flat architecture. They want to use a technology that allows them to interconnect many switches into a single logical fabric, providing redundancy and simplifying management. Which technology is designed for this purpose?

A pair of chassis switches with MC-LAG

A spine-and-leaf design with EVPN-VXLAN

A traditional three-tier hierarchy with Spanning Tree Protocol (STP)

A campus network has a traditional three-tier design with access, distribution, and core layers. The network team is planning to implement redundancy at each layer. They have a limited budget and want to prioritize the layer where a failure would cause the most widespread impact. Which layer should they prioritize for redundancy?

Distribution layer, because it aggregates traffic from access switches.

Core layer, because it interconnects all distribution blocks and a failure can isolate large parts of the network.

All layers equally, because any failure can cause downtime.

Access layer, because it has the most devices and users.

A company is deploying a pair of SRX Series firewalls at the edge of their data center to provide stateful failover for their internet-facing services. They require that existing sessions continue uninterrupted if one device fails, and they want to avoid any manual intervention. Which deployment model meets these requirements?

Use a single SRX device with redundant power supplies and link aggregation to the upstream and downstream switches.

Configure the two SRX devices in a chassis cluster with active/passive mode and enable synchronization of session state.

Place the two SRX devices in a chassis cluster with active/active mode, but disable session synchronization to avoid overhead.

Deploy the two SRX devices as standalone firewalls in parallel, each with its own default route, and rely on dynamic routing to redirect traffic.

Redundancy and High Availability JN0-1103 Practice Questions (Page 2)

Part of the Network Management and Reliability domain, which makes up ~12% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–2 from this objective — we provide 38 practice questions to prepare you well beyond it.
