Juniper JN0-335 Exam

Two benefits of using a cSRX in your virtual environment are:

The cSRX supports firewall, NAT, IPS, and UTM services: The cSRX is a containerized version of the SRX Series firewall that runs as a Docker container on Linux hosts. It provides the same features and functionality as the SRX Series physical firewalls, such as firewall, NAT, IPS, and UTM services. The cSRX can protect your virtual workloads and applications from various threats and attacks.

The cSRX has low memory requirements: The cSRX is designed to be lightweight and efficient, with low memory and CPU requirements. The cSRX can run on as little as 1 GB of RAM and 1 vCPU, making it suitable for resource-constrained environments.

The service that you would implement at your edge device to prioritize VoIP traffic in this scenario is AppQoS. AppQoS is a feature that enables you to allocate bandwidth and prioritize traffic based on application signatures or custom rules. AppQoS can enhance the quality of service and experience for critical or latency-sensitive applications, such as VoIP. You can configure AppQoS policies to assign different classes of service (CoS) values or queue numbers to different applications or traffic flows. You can also define bandwidth limits, guarantees, or bursts for each class or queue.Reference:= [Application Quality of Service Overview], [Configuring Application Quality of Service]

Juniper ATP Cloud is a cloud-based service that provides advanced threat prevention and detection for your network. It integrates with SRX Series firewalls and MX Series routers to analyze files and network traffic for signs of malicious activity. Two functions that Juniper ATP Cloud performs to reduce delays in the inspection of files are:

Juniper ATP Cloud allows the creation of allowlists: Allowlists are lists of trusted files or file hashes that are excluded from scanning by Juniper ATP Cloud. You can create allowlists based on file name, file type, file size, file hash, or sender domain. By using allowlists, you can reduce the number of files that need to be uploaded to Juniper ATP Cloud for analysis and improve the performance and efficiency of your network.

Juniper ATP Cloud performs a cache lookup on files: Cache lookup is a process that checks if a file has been previously scanned by Juniper ATP Cloud and if there is a cached verdict for it. If there is a cached verdict, Juniper ATP Cloud returns it immediately without scanning the file again. If there is no cached verdict, Juniper ATP Cloud uploads the file for analysis. By using cache lookup, you can reduce the time and bandwidth required for scanning files by Juniper ATP Cloud.

The DNS ALG is an application layer gateway that handles data associated with locating and translating domain names into IP addresses. It runs on port 53 and monitors DNS query and reply packets. Two statements about the DNS ALG that are correct are:

The DNS ALG supports DDNS: DDNS is Dynamic DNS, which is a method of updating DNS records in real time to reflect changes in network configurations or hostnames. The DNS ALG can process DDNS messages differently from DNS messages and perform address translation in the query part of the message.

The DNS ALG performs DNS doctoring: DNS doctoring is a technique of modifying the DNS reply packets to replace the original IP addresses with translated IP addresses that are suitable for the destination network. This allows the clients to access servers that are located behind NAT devices or in different networks.
