Exam JN0-335 topic 1 question 39 discussion

AppTrack, an application tracking tool, provides statistics for analyzing bandwidth usage of your network. When enabled, AppTrack collects byte, packet, and duration statistics for application flows in the specified zone. By default, when each session closes, AppTrack generates a message that provides the byte and packet counts and duration of the session, and sends it to the host device. Juniper Secure Analytics (formally known as STRM) retrieves the data and provides flow-based application visibility www.juniper.net/documentation/us/en/software/junos/application-identification/topics/topic-map/security-application-tracking.html

Solution: The AppSecure AppTrack service module is a logging and reporting tool used to share information about application visibility. Once AppID identifies an application, AppTrack not only monitors and records its usage, it also sends regular application activity update messages. Since these messages are sent by syslog, they can be read by any compatible third-party device, including Juniper Networks JSA Series Secure Analytics Appliances and Contrail Service Orchestration. https://www.juniper.net/content/dam/www/assets/solution-briefs/us/en/appsecure-application-visibility-and-control.pdf

Answer is A AppTrack: Tracks and reports applications passing through the device. • Intrusion Detection and Prevention (IDP): Applies appropriate attack objects to applications running on nonstandard ports. Application identification improves IDP performance by narrowing the scope of attack signatures for applications without decoders. • AppFW: Implements an application firewall using application-based rules. • AppQoS: Provides quality-of-service (QoS) prioritization based on application awareness
