In SRX chassis clustering, what is the role of the control plane redundancy?

To synchronize the configuration between the nodes

To ensure that routing and management functions continue if the primary control plane fails

To encrypt all control traffic between the nodes

To provide additional processing power for data plane traffic

A company is deploying a pair of routers at the edge of their network to provide gateway redundancy. They want to ensure that if one router fails, the other takes over the gateway IP address and continues to route traffic. They also want to minimize the failover time. Which technology should they use?

Link Aggregation Group (LAG) between the two routers

Virtual Router Redundancy Protocol (VRRP)

Spanning Tree Protocol (STP) to provide a redundant path

Equal-Cost Multipath (ECMP) with both routers advertising the same gateway IP

What is the primary purpose of Virtual Chassis Fabric (VCF) in a data center network?

To replace the need for firewalls in the data center

To encrypt all data center traffic

To provide a dedicated backup link for each server

To scale the network by interconnecting multiple switches into a single logical fabric

Which SRX redundancy mode is best suited for a design that requires both nodes to actively forward traffic and provide load sharing?

Cluster mode with no synchronization

A data center is deploying EVPN-VXLAN with ESI LAG for server multihoming. The network team wants to ensure that if one of the links in the ESI LAG fails, the traffic is seamlessly redirected to the remaining link without any packet loss. Which mechanism is responsible for this failover?

The server detects the link failure and reroutes traffic to the other link using a routing protocol.

The VXLAN tunnel is re-established to the other leaf, causing a brief interruption.

The spine switches detect the link failure and reroute traffic to the other leaf.

The leaf switches use the ESI to coordinate and update their forwarding tables, and the remaining link continues to forward traffic.

Redundancy and High Availability JN0-1103 Practice Questions (Page 7)

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.
