NEW QUESTION # 59
You need to secure communications from a mobile command center which uses a 5G mobile ISP behind CGNAT to an SRX Series Firewall at headquarters.
Which two actions should be performed on the SRX Series Firewall in this scenario? (Choose two.)
Answer: C,D
Explanation:
The correct answers are A and D. A mobile command center using a 5G ISP behind CGNAT is operating behind dynamic address translation. For IPsec to work reliably through NAT, the SRX must support NAT Traversal, which encapsulates IKE and ESP traffic in UDP/4500 after NAT is detected. Juniper states that NAT-T is used when NAT devices exist in the datapath and that NAT keepalives are required because NAT devices age out UDP translations. Juniper's Security Director VPN workflow also specifically says to enable NAT-T when the dynamic endpoint is behind a NAT device.
DPD is also required because mobile and carrier-grade NAT connections can disappear, roam, or become stale without a clean tunnel teardown. Juniper defines Dead Peer Detection as the method used by IPsec peers to verify whether the remote peer is still present and responsive by sending encrypted IKE notification payloads and waiting for acknowledgements. Option B is not the best answer because IKEv1 aggressive mode is weaker and does not provide identity protection; Juniper also notes that aggressive mode applies only to IKEv1. Option C is invalid because IKEv2 aggressive mode does not exist. Reference topics: IPsec VPN, NAT-T, CGNAT, dynamic endpoints, DPD, IKE peer availability.

Which two functions does Juniper ATP Cloud perform to reduce delays in the inspection of files?
(Choose two.)
Answer: A,B
Explanation:
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.

NEW QUESTION # 61
Which two statements are correct about the Junos IPS feature? (Choose two.)
Answer: C,D
Explanation:
Junos IPS is a feature that provides intrusion prevention and detection services on SRX Series devices.
It monitors network traffic and compares it against predefined signatures or custom rules to identify and block malicious or unwanted packets. Two statements that are correct about the Junos IPS feature are:
IPS is integrated as a security service on SRX Series devices: Junos IPS is not a separate platform or device, but a security service that runs on SRX Series firewalls. It can be enabled and configured as part of the security policy on the SRX Series device and applied to specific zones, interfaces, or traffic flows.
IPS uses protocol anomaly rules to detect unknown attacks: Junos IPS uses two types of rules to detect attacks: signature rules and protocol anomaly rules. Signature rules match traffic against known attack patterns or signatures and block them based on predefined actions. Protocol anomaly rules detect deviations from the expected behavior or structure of common protocols, such as TCP, UDP, ICMP, etc.
Protocol anomaly rules can help identify unknown or zero-day attacks that may not have a signature yet.

NEW QUESTION # 62
What are two benefits of using a vSRX in a software-defined network? (Choose two.)
Answer: B,D
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 # 63
You are asked to ensure that if the session table on your SRX Series device gets close to exhausting its resources, that you enforce a more aggress.ve age-out of existing flows.
In this scenario, which two statements are correct? (Choose two.)
Answer: A,C
Explanation:
The early-ageout configuration specifies the timeout value, in seconds, that will be applied once the high- watermark value is met. The high-watermark configuration specifies the percentage of how much of the session table can be allocated before applying a more aggressive age-out timer. This ensures that the session table does not become full and cause traffic issues, and also ensures that existing flows are aged out quickly when the table begins to get close to being full.
