Juniper JN0-335 Exam With Confidence Using Practice Dumps

 SSL proxy is a transparent proxy that performs SSL encryption and decryption between the client and the server. It allows inspection of encrypted traffic by terminating the SSL connection from either end and applying security policies to the clear text. SSL proxy can leverage pre-match or post-match results to determine whether to apply SSL proxy to a session. Pre-match results are based on the initial packet of the session, while post-match results are based on the application identification after the session is established. In the exhibit, the session shows that the application services identification is “ssl-proxy”, which means that SSL proxy is applied based on the pre-match results. The cache lookup status for application services is “on”, which means that the SRX Series device uses the application system cache to store the pre-match results for faster processing. Therefore, the correct answer is D. SSL proxy leverages pre-match result. References: = SSL Proxy, Configuring SSL Proxy, and Application System Cache

Policy Enforcer is a Junos Space Security Director component that allows updated security policies to be deployed across Juniper SRX Series firewalls, MX Series 5G Universal Routing Platforms, EX Series Ethernet Switches, QFX Series Switches, and third-party network devices1. Policy Enforcer can leverage the DDoS protection feature of Juniper devices to detect and mitigate DDoS attacks on the network. The DDoS protection feature is based on two main components: the classification of host-bound control plane traffic and a hierarchical set of individual- and aggregate-level policers that cap the volume of control plane traffic that each protocol type is able to send to the Routing Engine (RE) for processing2. The DDoS protection feature is supported on MX Series routers and QFX Series switches, among other devices3. Therefore, the correct devices to use for DDoS protection with Policy Enforcer are MX and QFX.

The other options are not correct for the following reasons:

• vQFX is a virtual switch that emulates the QFX Series switches for testing and development purposes. It does not support the DDoS protection feature4.
• vMX is a virtual router that emulates the MX Series routers for testing and development purposes. It does not support the DDoS protection feature.

SSL proxy uses application identification services to dynamically detect if a particular session is SSL encrypted.
