What are two valid modes for the Juniper ATP Appliance? (Choose two.)
Answer(s): C,D
The two valid modes for the Juniper ATP Appliance are all-in-one and core. The all-in-one mode is a single appliance that performs both the collector and the core functions. The collector function collects traffic from the network and sends it to the core function for analysis and detection. The core function performs the threat detection, mitigation, and analytics. The all-in-one mode is suitable for small to medium-sized networks that do not require high scalability or performance. The core mode is a dedicated appliance that performs only the core function. The core mode is used in conjunction with one or more collector appliances that collect traffic from the network and send it to the core appliance for analysis and detection. The core mode is suitable for large-scale networks that require high scalability and performance.

ExhibitReferring to the exhibit, an internal host is sending traffic to an Internet host using the 203.0.113.1 reflexive address with source port 54311.Which statement is correct in this situation?
Answer(s): B
According to the Juniper documentation, reflexive NAT is a type of source NAT that allows an internal host to communicate with an external host using a single public IP address and port. The reflexive NAT session is created when the internal host initiates the traffic to the external host, and the session is deleted when the traffic stops. The reflexive NAT session is bidirectional, meaning that the external host can send traffic back to the internal host using the same public IP address and port that the internal host used to reach the external host. However, the external host cannot initiate a new session to the internal host using the same public IP address and port, unless the internal host has already established a session with the external host. Therefore, only the Internet host that the internal host originally communicated with can initiate traffic to reach the internal host using the 203.0.113.1 address, a random source port, and destination port 54311.
[Configuring Reflexive NAT]
Your IPsec VPN configuration uses two CoS forwarding classes to separate voice and data traffic. How many IKE security associations are required between the IPsec peers in this scenario?
Answer(s): A
An IKE security association (SA) is a set of parameters that define how the Internet Key Exchange (IKE) protocol will authenticate and establish the secure channel between the IPsec VPN peers. When you configure an IPsec VPN, one IKE SA is created between the peers, regardless of how many CoS forwarding classes are used to separate the traffic. The SA will be used to negotiate the IPsec SA parameters, such as encryption algorithms and keys.In this scenario, only 1 IKE security association is required between the IPsec peers, no matter how many CoS forwarding classes are used to separate the voice and data traffic.
You are required to deploy a security policy on an SRX Series device that blocks all known Tor network IP addresses. Which two steps will fulfill this requirement? (Choose two.)
Answer(s): B,C
The two steps that will fulfill the requirement of deploying a security policy on an SRX Series device that blocks all known Tor network IP addresses are enrolling the devices with Juniper ATP Cloud and enabling a third-party Tor feed. Juniper ATP Cloud is a cloud-based service that provides advanced threat detection and mitigation capabilities for SRX Series devices. By enrolling the devices with Juniper ATP Cloud, the devices can leverage the cloud intelligence and analytics to identify and block malicious traffic, including Tor traffic. A third-party Tor feed is a source of information that provides a list of IP addresses that are associated with the Tor network. By enabling a third-party Tor feed on the SRX Series device, the device can use the feed to create a dynamic address object that contains all the known Tor IP addresses. The device can then apply a security policy that denies traffic from or to the dynamic address object, effectively blocking the Tor network IP addresses.

Your company uses non-Juniper firewalls and you are asked to provide a Juniper solution for zero-day malware protection. Which solution would work in this scenario?
Juniper ATP Cloud provides zero-day malware protection for non-Juniper firewalls. It's a cloud-based service that analyzes files and network traffic to detect and prevent known and unknown (zero-day) threats. It uses a combination of static and dynamic analysis techniques, as well as machine learning, to detect and block malicious files, even if they are not known to traditional anti-virus software. It also provides real-time visibility and detailed forensics for incident response and remediation.
