You are configuring logging for a security policy.
In this scenario, in which two situations would log entries be generated? (Choose two.)
- A. every 60 seconds
- B. every 10 minutes
- C. at session close
- D. at session initialization
Answer: C,D

NEW QUESTION # 50
Your manager asks you to provide firewall and NAT services in a private cloud.
Which two solutions will fulfill the minimum requirements for this deployment? (Choose two.)
- A. a cSRX for firewall services and a separate cSRX for NAT services
- B. a single vSRX
- C. a single cSRX
- D. a vSRX for firewall services and a separate vSRX for NAT services
Answer: A,D
Explanation:
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.

- B. AppTrack
- C. APPID
- D. AppFW
Answer: C,D
Explanation:
You can block applications and users based on network access policies, users and their job roles, time, and application signatures. You can also use Juniper Advanced Threat Prevention (ATP) to find and block commodity and zero-day cyberthreats within files, IP traffic, and DNS requests.
NEW QUESTION # 52

NEW QUESTION # 54
You are asked to implement IPS on your SRX Series device.
In this scenario, which two tasks must be completed before a configuration will work? (Choose two.)
- A. Enroll the SRX Series device with Juniper ATP Cloud.
- B. Reboot the SRX Series device.
- C. Download the IPS signature database.
- D. Install the IPS signature database.
Answer: C,D
Explanation:
The two tasks that must be completed before a configuration for IPS on an SRX Series device will work are downloading the IPS signature database and installing the IPS signature database. The Security, Specialist (JNCIS-SEC) Study guide provides further information on how to download and install the IPS signature database. Enrolling the SRX Series device with Juniper ATP Cloud is not necessary to make a configuration work, and rebooting the SRX Series device is not required either.
NEW QUESTION # 55
Which two statements describe IPS? (Choose two.)
- A. IPS can be used to prevent future attacks from occurring.
- B. IPS dynamically sends policy changes to SRX Series devices.
- C. IPS inspects up to Layer 4 in the OSI model.
- D. IPS inspects up to Layer 7 in the OSI model.
Answer: A,D

- C. Review the APBR statistics for matching rules and route modifications.
- D. Verity inet.0 for correct route leaking.
Answer: A,C
NEW QUESTION # 59
At which step in the packet flow are Junos Screen checks applied?
- A. after ALG services are applied

NEW QUESTION # 61
What are three capabilities of AppQoS? (Choose three.)
- A. reserve bandwidth
- B. assign a forwarding class
- C. re-write DSCP values
- D. rate-limit traffic
- E. re-write the TTL
Answer: A,B,C
Explanation:
AppQoS (Application Quality of Service) is a Junos OS feature that provides advanced control and prioritization of application traffic. With AppQoS, you can classify application traffic, assign a forwarding class to the traffic, and apply quality of service (QoS) policies to the traffic. You can also re-write DSCP values and reserve bandwidth for important applications. However, AppQoS does not re-write the TTL or rate-limit traffic.

NEW QUESTION # 62
Which two devices would you use for DDoS protection with Policy Enforcer? (Choose two.)
- A. vMX
- B. vQFX
- C. MX
- D. QFX
Answer: A,C
Explanation:
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.
NEW QUESTION # 63
What are two benefits of using a vSRX in a software-defined network? (Choose two.)
- A. infinite number of interfaces
- B. scalability
- C. granular security
- D. no required software license
Answer: B,C
Explanation:
Scalability: vSRX instances can be easily added or removed as the needs of the network change, making it a flexible option for scaling in a software-defined network.
Granular Security: vSRX allows for granular security policies to be enforced at the virtual interface level, making it an effective solution for securing traffic in a software-defined network.
The two benefits of using a vSRX in a software-defined network are scalability and granular security. Scalability allows you to increase the number of resources available to meet the demands of network traffic, while granular security provides a level of control and flexibility to your network security that is not possible with a traditional firewall. With a vSRX, you can create multiple levels of security policies, rules, and access control lists to ensure that only authorized traffic can enter and exit your network. Additionally, you would not require a software license to use the vSRX, making it an economical solution for those looking for increased security and flexibility.
NEW QUESTION # 64

- A. vSRX and cSRX both provide Layer 2 to Layer 7 secure services.
- B. vSRX provides faster deployment time and faster reboots compared to cSRX.
- C. vSRX provides Layer 2 to Layer 7 secure services and cSRX provides Layer 4 to Layer 7 secure services.
- D. cSRX requires less storage and memory space for a given deployment than vSRX-based solutions.
- E. cSRX-based solutions are more scalable than vSRX-based solutions.
