NEW QUESTION # 20
you are connecting two remote sites to your corporate headquarters site. You must ensure that traffic passes corporate headquarter.
- A. In this scenario, which VPN should be used?
- B. a Layer 3 VPN with the corporate firewall acting as the hub device
- C. full mesh IPsec VPNs with tunnels between all sites
- D. hub-and-spoke IPsec VPN with the corporate firewall acting as the hub device
- E. a full mesh Layer 3 VPN with the BGP route reflector behind the corporate firewall device
Answer: B
Explanation:
You are connecting two remote sites to your corporate headquarters site. You must ensure that traffic passes through the corporate headquarters. In this scenario, the VPN that should be used is:
D) Hub-and-spoke IPsec VPN with the corporate firewall acting as the hub device. A hub-and-spoke IPsec VPN is a type of VPN that connects multiple remote sites to a central site, or hub, over a public network. The hub site acts as a gateway for the remote sites and provides security and routing services. The remote sites, or spokes, communicate with each other through the hub site. The hub site and the spoke sites use IPsec tunnels to encrypt and authenticate the traffic between them. A hub-and-spoke IPsec VPN is suitable for connecting two remote sites to your corporate headquarters site, because it allows you to control the traffic flow and enforce security policies at the hub site. The corporate firewall can act as the hub device and provide IPsec VPN services to the remote sites1.
The other options are incorrect because:
A) Full mesh IPsec VPNs with tunnels between all sites. A full mesh IPsec VPN is a type of VPN that connects every site to every other site over a public network. Each site has an IPsec tunnel with every other site, forming a mesh topology. A full mesh IPsec VPN provides direct and secure communication between any pair of sites, but it also requires a large number of IPsec tunnels and complex configuration. A full mesh IPsec VPN is not suitable for connecting two remote sites to your corporate headquarters site, because it does not ensure that traffic passes through the corporate headquarters site, and it may introduce unnecessary overhead and complexity2.
B) A full mesh Layer 3 VPN with the BGP route reflector behind the corporate firewall device. A full mesh Layer 3 VPN is a type of VPN that uses MPLS and BGP to provide Layer 3 connectivity and routing between multiple sites over a service provider's network. Each site has a BGP session with every other site, forming a full mesh topology. A BGP route reflector is a device that reduces the number of BGP sessions required in a full mesh topology by reflecting routes between its clients. A full mesh Layer 3 VPN with the BGP route reflector behind the corporate firewall device is not suitable for connecting two remote sites to your corporate headquarters site, because it does not ensure that traffic passes through the corporate firewall device, and it may require additional configuration and coordination with the service provider3.
C) A Layer 3 VPN with the corporate firewall acting as the hub device. A Layer 3 VPN is a type of VPN that uses MPLS and BGP to provide Layer 3 connectivity and routing between multiple sites over a service provider's network. A Layer 3 VPN can have different topologies, such as full mesh, hub-and-spoke, or partial mesh. A Layer 3 VPN with the corporate firewall acting as the hub device is not suitable for connecting two remote sites to your corporate headquarters site, because the corporate firewall may not support MPLS and BGP, and it may require additional configuration and coordination with the service provider3.

NEW QUESTION # 21
Exhibit
Which two statements are correct about the output shown in the exhibit? (Choose two.)
- A. The packet is part of a new session.
- B. The packet is explicitly rejected.
- C. The packet is part of an existing session.
- D. The packet is silently discarded.
Answer: A,D
Explanation:
The packet is silently discarded because the traceoptions output shows that the packet is dropped with the flag flow_spu_drop, which indicates that the packet is dropped by the SPU without sending any response to the sender. The traceoptions output also shows the reason for the drop as "no session found, start first path. in_tunnel - 0, from_cp_flag - 0" which means that the packet does not match any existing session and is not part of a tunnel or a control plane traffic1.
The packet is part of a new session because the traceoptions output shows that the packet is the first packet of a TCP connection with the flag flow_tcp_syn, which indicates that the packet has the SYN flag set. The traceoptions output also shows that the packet is processed in the first path packet flow with the message "no session found, start first path" which means that the packet is initiating a new session1.

Exhibit
Referring to the exhibit, which type of NAT is being performed?
- A. Destination NAT
- B. Source NAT
- C. Persistent NAT
- D. Static NAT
Answer: B
Explanation:
Source NAT is a type of NAT that is used to translate the source IP address and port number of a packet. This is typically used to allow multiple devices on a private network to access the internet using a single public IP address. In the exhibit, we can see that the source IP address and port number of the packet are being translated from 10.10.10.2/61606 to 203.0.113.100/179. This is a clear indication that Source NAT is being performed. Reference:

NEW QUESTION # 28
You are asked to deploy Juniper atp appliance in your network. You must ensure that incidents and alerts are sent to your SIEM.
In this scenario, which logging output format is supported?
- A. WELF
- B. CEF
- C. binay
- D. JSON
Answer: B
Explanation:
The Juniper ATP Appliance platform collects, inspects and analyzes advanced and stealthy web, file, and email-based threats that exploit and infiltrate client browsers, operating systems, emails and applications. Juniper ATP Appliance's detection of malicious attacks generates incident and event details that can be sent to connected SIEM platforms in CEF, LEEF or Syslog formats1. CEF (Common Event Format) is an open log management standard that improves the interoperability of security-related information from different vendors2. Juniper ATP Appliance supports CEF format for sending events and system audit notifications to SIEM servers. You can configure the CEF format in the Juniper ATP Appliance Central Manager WebUI Config > Notifications > SIEM Settings1. Therefore, the correct answer is C. CEF is a supported logging output format for Juniper ATP Appliance. The other options are incorrect because:
A) WELF (WebTrends Enhanced Log Format) is a proprietary log format developed by WebTrends Corporation for web analytics3. Juniper ATP Appliance does not support WELF format for SIEM integration.
B) JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans and machines to read and write4. Juniper ATP Appliance supports JSON format for HTTP API results, but not for SIEM notifications1.
D) Binary is a numeric system that uses only two digits: 0 and 1. Binary is not a logging output format for Juniper ATP Appliance or any SIEM platform.

NEW QUESTION # 30
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.)
- A. Enable a third-party Tor feed.
- B. Enroll the devices with Juniper ATP Cloud.
- C. Enroll the devices with Juniper ATP Appliance.
- D. Create a custom feed containing all current known MAC addresses.
Answer: A,B
Explanation:
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.

NEW QUESTION # 33
Exhibit
Referring to the exhibit, which two statements are true? (Choose two.)
- A. The 3uspicious_Endpoint3 feed is only usable by the SRX-1 device.
- B. Juniper ATP Cloud automatically creates the 3uopi'cioua_Endpoints feed after you commit the security policy.
- C. The 3uspiciou3_Endpoint3 feed is usable by any SRX Series device that is a part of the same realm as SRX-1
- D. You must manually create the suspicious_Endpoint3 feed in the Juniper ATP Cloud interface.
Answer: B,C
Explanation:
The suspicious_Endpoints feed is a dynamic address group that is created by Juniper ATP Cloud based on the IoT device discovery and policy enforcement feature. This feature allows the SRX Series device to send IoT traffic to Juniper ATP Cloud for analysis and classification. Juniper ATP Cloud then creates a threat feed that contains the IP addresses of the suspicious IoT devices and sends it back to the SRX Series device. The SRX Series device can then use this feed to create and enforce security policies for the IoT traffic. The suspicious_Endpoints feed is usable by any SRX Series device that is a part of the same realm as SRX-1, because the feed is shared among the devices that belong to the same Juniper ATP Cloud realm. Juniper ATP Cloud automatically creates the suspicious_Endpoints feed after you commit the security policy that references the feed, because the feed is dynamically generated based on the IoT traffic analysis. You do not need to manually create the feed in the Juniper ATP Cloud interface. Reference:

NEW QUESTION # 34
While troubleshooting security policies, you added the count action. Where do you see the result of this action?
- A. In the show security policies hit-count command output.
- B. In the show firewall log command output.
- C. In the show security flow statistics command output.
- D. In the show security policies detail command output.
Answer: D
Explanation:
The result of adding the count action to a security policy can be seen in the show security policies detail command output. The count action is a feature that allows you to enable statistics collection for sessions that enter the device for a given policy, and for the number of packets and bytes that pass through the device in both directions for a given policy. The count action can help you to monitor the traffic that matches a security policy and to troubleshoot security policy issues. The show security policies detail command displays the detailed information about the security policies configured on the device, including the count statistics. The output shows the number of packets and bytes that have been processed by the policy in both directions, as well as the number of sessions that have been created by the policy. You can use this command to verify that the count action is working as expected and to see the traffic volume and session count for each policy.
