Juniper JN0-335 Exam With Confidence Using Practice Dumps

 This is because the error message indicates that the client device does not trust the certificate authority that issued the certificate for the external server. Therefore, you need to import the root CA certificate from the SRX Series device to the client device and add it to the trusted certificate store. This will allow the client device to verify the identity of the SRX Series device and accept the certificates it generates for the external servers3.

The other options are not correct because:

• A. Load a known good, but expired. CA certificate onto the SRX Series device. This will not solve the problem because the client device will still reject the certificates from the SRX Series device if they are signed by an expired CA certificate. The expiration date of the CA certificate is one of the factors that the client device checks when validating the certificate2.
• B. Install a new SRX Series device to act as the client proxy. This will not solve the problem because the new SRX Series device will still need to have a root CA certificate configured and imported to the client devices. The problem is not with the SRX Series device itself, but with the trust relationship between the SRX Series device and the client devices2.
• C. Reboot the SRX Series device. This will not solve the problem because rebooting the SRX Series device will not change the configuration or the certificates on the SRX Series device or the client devices. The problem is not caused by a temporary glitch or a malfunction, but by a mismatch between the certificates on the SRX Series device and the client devices2.

I hope this helps you understand the problem and the solution better. If you want to learn more about SSL client protection proxy, you can check out the following references:

The vSRX is a virtual firewall that offers the same features as the physical SRX Series firewalls, but in a virtualized form factor for delivering security services that scale to match network demand. It offers the same features as the SRX appliance, including core firewall, robust networking, full next-gen capabilities, and automated life-cycle management1

The vSRX supports Layer 2 and Layer 3 configurations, which means it can operate as a transparent or a routed firewall, depending on the network topology and requirements. The vSRX can also support multiple routing instances, such as virtual routers, virtual switches, and logical systems, to provide logical separation and isolation of traffic2

The vSRX provides clustering, which enables two or more vSRX instances to act as a single, logical device that provides high availability, load balancing, and scalability. The vSRX cluster can synchronize configuration and session information, and support stateful failover and redundancy groups3

The cSRX is a containerized firewall that offers a compact footprint with a high-density firewall for virtualized and cloud environments. It is designed to secure microservices and containerized applications, and provide network visibility and threat prevention4

The cSRX does not support Layer 2 and Layer 3 configurations, as it is intended to be a lightweight and agile firewall that does not perform dynamic routing or networking functions. The cSRX relies on the underlying container orchestration platform, such as Kubernetes or Docker, to provide the network connectivity and management4

The cSRX does not provide clustering, as it is designed to leverage the native resiliency and scalability features of the container orchestration platform. The cSRX can be deployed as a standalone firewall or as part of a service chain, and can be dynamically scaled up or down based on the demand4

The cSRX has faster boot times than the vSRX, as it can be instantiated in seconds, compared to minutes for the vSRX. The cSRX also has a smaller image size and memory requirement than the vSRX, as it is optimized for containerized environments4

The cSRX provides NAT, IPS, and UTM services, similar to the vSRX, but with some limitations. The cSRX does not support IPSec VPN, application identification, user firewall, or SSL proxy. The cSRX also has lower performance and throughput than the vSRX, as it is constrained by the container resources and the orchestration platform4

 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
