Juniper Security, Specialist JN0-335 Exam Practice Test

Answer : A, C

you can block applications and users based on network access policies, users and their job roles, time, and application signatures2.You can also use Juniper Advanced Threat Prevention (ATP) to find and block commodity and zero-day cyberthreats within files, IP traffic, and DNS requests1

Answer : A, D

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.

Answer : B

Juniper Identity Management Service (JIMS) domain PC probes are used to map usernames to IP addresses in the domain security event log. This allows for the SRX Series device to verify authentication table information, such as group membership. The probes are triggered whenever a username to IP address mapping is not found in the domain security event log. By default, the probes are executed at 60-minute intervals.

Answer : A

Answer : B, C

A single vSRX or cSRX cannot provide both firewall and NAT services simultaneously. To meet the minimum requirements for this deployment, you need to deploy a vSRX for firewall services and a separate vSRX for NAT services (option B), or a cSRX for firewall services and a separate cSRX for NAT services (option C). This is according to the Juniper Networks Certified Security Specialist (JNCIS-SEC) Study Guide.

Answer : B, C

The MX and vMX devices can be used for DDoS protection with Policy Enforcer. Policy Enforcer is a Juniper Networks solution that provides real-time protection from DDoS attacks. It can be used to detect and block malicious traffic, and also provides granular control over user access and policy enforcement. The MX and vMX devices are well-suited for use with Policy Enforcer due to their high-performance hardware and advanced security features.

Answer : B, D

The Flow Collector can use statistical sampling to collect and store network flow data in the JSA database. The Event Collector collects information from various sources including syslog, SNMP, NetFlow, and BGP FlowSpec. Both the Flow Collector and the Event Collector parse logs to extract useful information from the logs.
