NEW QUESTION # 23
which security feature bypasses routing or switching lookup?
- A. mixed mode
- B. secure wire
- C. transparent mode
- D. MACsec
Answer: C
Explanation:
The security feature that bypasses routing or switching lookup is transparent mode. The other options are incorrect because:
B) Secure wire is a feature that allows you to connect two interfaces on the same device and forward traffic between them without any processing. Secure wire does not bypass routing or switching lookup, but rather eliminates them altogether1.
C) Mixed mode is a mode of operation for SRX Series devices that allows you to configure both transparent mode and switching mode on the same device. Mixed mode does not bypass routing or switching lookup, but rather uses them depending on the interface type2.
D) MACsec (Media Access Control Security) is a feature that provides encryption and authentication for Layer 2 traffic. MACsec does not bypass routing or switching lookup, but rather operates at a lower layer3.
Therefore, the correct answer is
A) Transparent mode is a mode of operation for SRX Series devices that provides Layer 2 bridging capabilities with full security services. In transparent mode, the SRX Series device acts as a bridge between two network segments and inspects the packets without modifying the source or destination information in the IP packet header. The SRX Series device does not have an IP address in transparent mode, except for the management interface. Transparent mode bypasses routing or switching lookup, because the SRX Series device does not perform any routing or switching functions, but rather forwards the packets based on the MAC addresses4.

NEW QUESTION # 26
Exhibit
You have configured the SRX Series device to switch packets for multiple directly connected hosts that are within the same broadcast domain However, the traffic between two hosts in the same broadcast domain are not matching any security policies Referring to the exhibit, what should you do to solve this problem?
- A. You must change the global mode to transparent bridge mode.
- B. You must change the global mode to security switching mode.
- C. You must change the global mode to switching mode.
- D. You must change the global mode to security bridging mode
Answer: A
Explanation:
According to the exhibit, which is a configuration snippet of the SRX Series device, the global mode for the device is set to switching mode. This means that the device is operating as a Layer 2 switch and does not apply any security policies to the traffic between hosts in the same broadcast domain1. Therefore, the traffic between two hosts in the same broadcast domain are not matching any security policies.
To solve this problem, the user should change the global mode to transparent bridge mode. This means that the device will operate as a Layer 2 transparent bridge and apply security policies to the traffic between hosts in the same broadcast domain2. This will allow the user to enforce security policies based on the source and destination IP addresses, ports, and protocols of the traffic.
To change the global mode to transparent bridge mode, the user should use the following command:
set protocols l2-learning global-mode transparent-bridge
This command will set the global mode for the SRX Series device as Layer 2 transparent bridge mode. After changing the mode, the user must reboot the device for the configuration to take effect2.
NEW QUESTION # 27
SRX Series device enrollment with Policy Enforcer fails To debug further, the user issues the following command show configuration services security-intelligence url
https : //cloudfeeds . argon . juniperaecurity . net/api/manifeat. xml
and receives the following output:
What is the problem in this scenario?
- A. The SRX Series device does not have a valid license.
- B. The device is already enrolled with Policy Enforcer.
- C. Junos Space does not have matching schema based on the
- D. The device is directly enrolled with Juniper ATP Cloud.
Answer: A
Explanation:
According to the output of the command show configuration services security-intelligence url, the SRX Series device is directly enrolled with Juniper ATP Cloud. This is indicated by the URL https://cloudfeeds.argon.junipersecurity.net/api/manifest.xml, which is the default URL for Juniper ATP Cloud1. This means that the device is not enrolled with Policy Enforcer, which would use a different URL that includes the IP address of the Policy Enforcer server2. Therefore, the problem in this scenario is that the device is directly enrolled with Juniper ATP Cloud, which prevents it from being enrolled with Policy Enforcer.
To enroll the device with Policy Enforcer, the user needs to disenroll the device from Juniper ATP Cloud first. This can be done by using the following command:
delete services security-intelligence url
This command will remove the Juniper ATP Cloud URL from the device configuration and stop the device from receiving threat feeds from Juniper ATP Cloud1. After that, the user can enroll the device with Policy Enforcer by using the Security Director GUI or the SLAX script2.

Referring to the exhibit, which three protocols will be allowed on the ge-0/0/5.0 interface? (Choose three.)
- A. IPsec
- B. DHCP
- C. NTP
- D. OSPF
- E. IBGP
Answer: B,C,D
Explanation:
The exhibit shows the output of the "show interfaces ge-0/0/5.0 extensive" command on an SRX Series device. The output includes a section called "Security" that lists the protocols that are allowed on the ge-0/0/5.0 interface. The protocols that are allowed on the ge-0/0/5.0 interface are:
OSPF
DHCP
NTP
It's important to notice that the output don't have IBGP, IPsec, so these protocols are not allowed on the ge-0/0/5.0 interface.
NEW QUESTION # 30
Exhibit:
Referring to the exhibit, your company's infrastructure team implemented new printers To make sure that the policy enforcer pushes the updated Ip address list to the SRX.
Which three actions are required to complete the requirement? (Choose three )
- A. Configure Security Director to create a dynamic address feed
- B. Configure Security Director to create a C&C feed.
- C. Create a security policy that uses the dynamic address feed to allow access
- D. Configure the server feed URL as http://172.25.10.254/myprinters
- E. Configure server feed URL as https://172.25.10.254/myprinters.
Answer: A,C,D
Explanation:
Referring to the exhibit, your company's infrastructure team implemented new printers. To make sure that the policy enforcer pushes the updated IP address list to the SRX, you need to perform the following actions:
A) Configure the server feed URL as http://172.25.10.254/myprinters. The server feed URL is the address of the remote server that provides the custom feed data. You need to configure the server feed URL to match the location of the file that contains the IP addresses of the new printers. In this case, the file name is myprinters and the server IP address is 172.25.10.254, so the server feed URL should be http://172.25.10.254/myprinters1.
B) Create a security policy that uses the dynamic address feed to allow access. A security policy is a rule that defines the action to be taken for the traffic that matches the specified criteria, such as source and destination addresses, zones, protocols, ports, and applications. You need to create a security policy that uses the dynamic address feed as the source or destination address to allow access to the new printers. A dynamic address feed is a custom feed that contains a group of IP addresses that can be entered manually or imported from external sources. The dynamic address feed can be used in security policies to either deny or allow traffic based on either source or destination IP criteria2.
C) Configure Security Director to create a dynamic address feed. Security Director is a Junos Space application that enables you to create and manage security policies and objects. You need to configure Security Director to create a dynamic address feed that contains the IP addresses of the new printers. You can create a dynamic address feed by using the local file or the remote file server option. In this case, you should use the remote file server option and specify the server feed URL as http://172.25.10.254/myprinters3.
The other options are incorrect because:
D) Configuring Security Director to create a C&C feed is not required to complete the requirement. A C&C feed is a security intelligence feed that contains the IP addresses of servers that are used by malware or attackers to communicate with infected hosts. The C&C feed is not related to the new printers or the dynamic address feed.
E) Configuring the server feed URL as https://172.25.10.254/myprinters is not required to complete the requirement. The server feed URL can use either the HTTP or the HTTPS protocol, depending on the configuration of the remote server. In this case, the exhibit shows that the remote server is using the HTTP protocol, so the server feed URL should use the same protocol1.

NEW QUESTION # 34
You must setup a Ddos solution for your ISP. The solution must be agile and not block legitimate traffic.
Which two products will accomplish this task? (Choose two.)
- A. Corero Smartwall TDD
- B. MX Series device
- C. Contrail Insights
- D. SRX Series device
Answer: A,B
Explanation:
You must set up a DDoS solution for your ISP. The solution must be agile and not block legitimate traffic. The two products that will accomplish this task are:
B) MX Series device. MX Series devices are high-performance routers that can provide DDoS protection at the network edge by integrating with Corero SmartWall Threat Defense Director (TDD) software. MX Series devices can leverage the packet processing capabilities of the MX-SPC3 Services Card to perform real-time DDoS detection and mitigation at line rate, scaling from 50 Gbps to 40 Tbps. MX Series devices can also use Juniper Networks Security Intelligence (SecIntel) to receive threat intelligence feeds from Juniper ATP Cloud or Juniper Threat Labs and apply them to the security policies. MX Series devices can provide an agile and effective DDoS solution for your ISP without blocking legitimate traffic12.
C) Corero SmartWall TDD. Corero SmartWall TDD is a software solution that runs on MX Series devices and PTX Series devices to provide DDoS protection at the network edge. Corero SmartWall TDD uses behavioral analytics and detailed network visibility to detect and block DDoS attacks in seconds, without affecting the normal traffic. Corero SmartWall TDD can also provide advanced protection from "carpet bombing" attacks, 5G DDoS visibility, and multi-tenant portal for as-a-service offerings or views by department within an enterprise. Corero SmartWall TDD can provide an agile and effective DDoS solution for your ISP without blocking legitimate traffic34.
The other options are incorrect because:
A) Contrail Insights. Contrail Insights is a software solution that provides network analytics and visibility for cloud and data center environments. Contrail Insights can help you monitor, troubleshoot, and optimize the performance and security of your network, but it does not provide DDoS protection by itself. Contrail Insights can integrate with other Juniper products, such as Contrail Enterprise Multicloud, Contrail Service Orchestration, and AppFormix, to provide a comprehensive network management solution, but it is not a DDoS solution for your ISP5.
D) SRX Series device. SRX Series devices are high-performance firewalls that can provide DDoS protection at the network perimeter by integrating with Juniper ATP Cloud and Juniper Threat Labs. SRX Series devices can use SecIntel to receive threat intelligence feeds from Juniper ATP Cloud or Juniper Threat Labs and apply them to the security policies. SRX Series devices can also use IDP to detect and prevent application-level attacks, such as SQL injection, cross-site scripting, and buffer overflow. SRX Series devices can provide a robust and effective DDoS solution for your network, but they are not designed to handle high-volume DDoS attacks at the network edge, as MX Series devices and Corero SmartWall TDD are .

NEW QUESTION # 36
Which two modes are supported on Juniper ATP Cloud? (Choose two.)
- A. Layer 3 mode
- B. global mode
- C. transparent mode
- D. private mode
Answer: A,C
Explanation:
According to the Juniper documentation, Juniper ATP Cloud supports the following modes:
Layer 3 mode: In this mode, the SRX Series device acts as a Layer 3 gateway and routes traffic between different subnets. The SRX Series device performs NAT and security policy enforcement on the traffic and sends a copy of the traffic to Juniper ATP Cloud for analysis. This mode is suitable for networks that have multiple subnets and require NAT and firewall functions1 Transparent mode: In this mode, the SRX Series device acts as a Layer 2 bridge and forwards traffic between the same subnet. The SRX Series device does not perform NAT or security policy enforcement on the traffic, but sends a copy of the traffic to Juniper ATP Cloud for analysis. This mode is suitable for networks that have a single subnet and do not require NAT or firewall functions1 The other two modes, global mode and private mode, are not supported by Juniper ATP Cloud. Global mode is a configuration option for Juniper ATP Appliance, which is an on-premises solution that provides threat detection and prevention. Private mode is a configuration option for Juniper ATP Private Cloud, which is a cloud-based solution that provides threat detection and prevention within a private network23 Reference:
