JN0-335 Dumps with Practice Exam Questions Answers

 AppQoE is an AppSecure component that provides application quality of experience by monitoring the network performance and dynamically adjusting the traffic routing based on predefined policies1. AppQoE can detect excessive packet loss on a WAN link and route the traffic to another link that has better performance2. AppQoE can also prioritize the traffic based on the application type and user group3. AppQoE is suitable for accomplishing the task of routing traffic from the degraded link to the working link.

The other options are not correct for the following reasons:

• AppFW is an AppSecure component that provides application firewalling by enforcing granular policies to allow, deny, or limit access to applications based on user roles, locations, and devices4. AppFW does not monitor or adjust the traffic routing based on network performance.
• AppQoS is an AppSecure component that provides application quality of service by allocating bandwidth and shaping traffic based on application priority and user group. AppQoS does not monitor or adjust the traffic routing based on network performance.
• APBR is an AppSecure component that provides application-based routing by selecting the best path for each application based on predefined criteria such as latency, jitter, packet loss, and cost. APBR does not monitor the network performance dynamically or adjust the traffic routing automatically.

SRX chassis clustering is a high availability feature that allows two SRX Series devices to operate as a single logical device. The two devices are connected by a control link and a fabric link, which are used to synchronize the configuration, state, and traffic between the nodes. The control plane is responsible for managing the cluster configuration, monitoring the health and status of the nodes, and performing failover operations. The data plane is responsible for processing and forwarding the traffic through the cluster. SRX chassis clustering supports two modes for the data plane: active/passive and active/active. In active/passive mode, only one node is active for each redundancy group, which is a logical grouping of interfaces and services. The active node handles all the traffic for the redundancy group, while the passive node acts as a backup. In active/active mode, both nodes are active for different redundancy groups, and they can share the traffic load for the cluster. SRX chassis clustering supports only one mode for the control plane: active/passive. In this mode, only one node is the primary node, which is the master of the cluster configuration and the source of truth for the cluster state. The primary node also initiates the failover process in case of a node or interface failure. The other node is the secondary node, which is the slave of the cluster configuration and the backup of the cluster state. The secondary node takes over the primary role if the primary node fails or is manually disabled. References: Chassis Cluster Overview, SRX Series Chassis Cluster Configuration Overview, Chassis Cluster Overview

Static attack object groups are predefined groups of attack objects that are included in Juniper’s IPS signature database. These groups do not change automatically when Juniper updates the database. You must manually add matching attack objects to a custom group34 References:
