NEW QUESTION # 43
You want to bypass IDP for traffic destined to social media sites using APBR, but it is not working and IDP is dropping the session.
What are two reasons for this problem? (Choose two.)
- A. The session did not properly reclassify midstream to the correct APBR rule.
- B. IDP disable is not configured on the APBR rule.
- C. The application services bypass is not configured on the APBR rule.
- D. The APBR rule does a match on the first packet.
Answer: A,C
Explanation:
* Explanation of Answer A (Session Reclassification):
* APBR (Advanced Policy-Based Routing) requires the session to be classified based on the specified rule, which can change midstream as additional packets are processed. If the session was already established before the APBR rule took effect, the traffic may not be correctly reclassified to match the new APBR rule, leading to IDP (Intrusion Detection and Prevention) processing instead of being bypassed. This can occur especially when the session was already established before the rule change.
* Explanation of Answer C (Application Services Bypass):
* For APBR to work and bypass the IDP service, the application services bypass must be explicitly configured. Without this configuration, the APBR rule may redirect the traffic, but the IDP service will still inspect and potentially drop the traffic. This is especially important for traffic destined for specific sites like social media platforms where bypassing IDP is desired.
Example configuration for bypassing IDP services:
bash
set security forwarding-options advanced-policy-based-routing profile <profile-name> application-services- bypass Step-by-Step Resolution:
* Reclassify the Session Midstream:
* If the traffic was already being processed before the APBR rule was applied, ensure that the session is reclassified by terminating the current session or ensuring the APBR rule is applied from the start.
Command to clear the session:
bash
clear security flow session destination-prefix <ip-address>
* Configure Application Services Bypass:
* Ensure that the APBR rule includes the application services bypass configuration to properly bypass IDP or any other security services for traffic that should not be inspected.
Example configuration:
bash
set security forwarding-options advanced-policy-based-routing profile <profile-name> application-services- bypass Juniper Security Reference:
* Session Reclassification in APBR: APBR requires reclassification of sessions in real-time to ensure midstream packets are processed by the correct rule. This is crucial when policies change dynamically or new rules are added.
* Application Services Bypass in APBR: This feature ensures that security services such as IDP are bypassed for traffic that matches specific APBR rules. This is essential for applications where performance is a priority and security inspection is not necessary.
NEW QUESTION # 44
You have deployed a new site as shown in the exhibit. Hosts in the 10.10.10.0/24 network must access the DB1 server. The DB1 server must also have internet access the DB1 server encrypted.
Which two configuration statements will be required as part of the configuration on SRX1 to satisfy this requirement? (Choose two)
- A. set security macsec connectivity-association access-sw security-mode static-cak
- B. set security forwarding-options secure-wire access-sw interface ge-0/0/1.0
- C. set protocols 12-learning global mode transparent-bridge
- D. set security macsec interfaces ge-0/0/1 connectivity association access-sw
Answer: A,D
Explanation:
Option A is correct because it enables MACsec encryption on the interface (ge-0/0/1) by binding it to a Connectivity Association (CA) named access-sw.
Option C is correct because it defines the security mode for the MACsec association (static-cak), which is required for pre-shared key-based encryption.

NEW QUESTION # 47
Exhibit:
You created a Unified security policy called test on the network edge srx series firewall.
According to the firewall, this new security policy is not passing traffic.
Which two statements are correct in this scenario? (Choose two.)
- A. The source address cannot be any when a dynamic application is configured.
- B. The drop-http policy is a terminating rule and will drop the traffic.
- C. A match exists on the test policy, but the dynamic application is waiting to be discovered
- D. The test policy should be the last policy.
Answer: B,C
NEW QUESTION # 48
Refer to the exhibit,
which two potential violations will generate alarm ? (Choose Two)
- A. the number of policy violation by a destination TCP port
- B. the number of policy violations by a source network identifier
- C. the ratio of policy violation traffic compared to accepted traffic.
- D. the number of policy violation to an application within a specified period
Answer: B,D
Explanation:
The exhibit shows a security policy configuration with a threshold of 1000 policy violations by a source network identifier and a threshold of 10 policy violations to an application within a specified period. If either of these thresholds are exceeded, an alarm will be generated. Therefore, the correct answer is A and D. The other options are incorrect because:
B) The ratio of policy violation traffic compared to accepted traffic is not a criterion for triggering an alarm.
The security policy configuration does not specify any ratio or percentage of policy violation traffic that would cause an alarm.
C) The number of policy violation by a destination TCP port is also not a criterion for triggering an alarm.
The security policy configuration does not specify any threshold or duration for policy violation by a destination TCP port.

Which two statements are true in this scenario? (Choose two.)
- A. The local and remote gateways do not need the forwarding classes to be defined in the same order.
- B. A maximum of four forwarding classes can be configured for a VPN with the multi-sa forwarding- classes statement.
- C. The local and remote gateways must have the forwarding classes defined in the same order.
- D. A maximum of eight forwarding classes can be configured for a VPN with the multi-sa forwarding- classes statement.
Answer: A,D
NEW QUESTION # 50
you are connecting two remote sites to your corporate headquarters site. You must ensure that traffic passes corporate headquarter.
- A. full mesh IPsec VPNs with tunnels between all sites
- B. In this scenario, which VPN should be used?
- C. hub-and-spoke IPsec VPN with the corporate firewall acting as the hub device
- D. a full mesh Layer 3 VPN with the BGP route reflector behind the corporate firewall device
- E. a Layer 3 VPN with the corporate firewall acting as the hub device
Answer: C
Explanation:
The most appropriate VPN topology when you need to ensure that all traffic from remote sites passes through the corporate headquarters would be a hub-and-spoke model. In this model, the corporate headquarters acts as the hub, and all remote sites (spokes) connect to it. This ensures that inter-site traffic goes through the headquarters, which can be important for security policy enforcement, logging, or other centralized services.
Hub-and-spoke IPsec VPN with the corporate firewall acting as the hub device - This setup will ensure that all traffic from the remote sites is routed through the corporate headquarters, allowing centralized control and inspection of the traffic.
NEW QUESTION # 51
You are enabling advanced policy-based routing. You have configured a static route that has a next hop from the inet.0 routing table. Unfortunately, this static route is not active in your routing instance.
In this scenario, which solution is needed to use this next hop?
- A. Use filter-based forwarding.
- B. Use RIB groups.
- C. Use transparent mode.
- D. Use policies.
Answer: B
Explanation:
To enable advanced policy-based routing in Junos OS and activate a static route with a next-hop address in the inet.0 table within your routing instance, you should utilize RIB groups. RIB groups allow you to import routes from one routing table to another. In this scenario, the static route within the routing instance needs access to the inet.0 routes, which is facilitated by configuring a RIB group. Juniper's documentation outlines RIB groups as a necessary component for handling instances where routes need to be shared across routing tables, thereby ensuring seamless traffic flow through specified routes. For more details, refer to the Juniper Networks Documentation on RIB Groups.
In Junos OS for SRX Series devices, when enabling advanced policy-based routing and configuring a static route with a next-hop from the inet.0 routing table, the issue arises because the static route is not being used in the routing instance. This is a common scenario when the next-hop belongs to a different routing table or instance, and the routing instance is not aware of that next-hop.
To resolve this, RIB (Routing Information Base) groups are used. RIB groups allow routes from one routing table (RIB) to be shared or imported into another routing table. This means that the routing instance can import the necessary routes from inet.0 and make them available for the routing instance where the policy- based routing is applied.
Detailed Steps:
* Configure the Static Route: First, configure the static route pointing to the next-hop in inet.0. Here's an example:
bash
set routing-options static route 10.1.1.0/24 next-hop 192.168.1.1
This static route will be placed in the inet.0 routing table by default.
* Create and Apply a RIB Group: To import routes from inet.0 into the routing instance, create a RIB group configuration. This will allow the static route from inet.0 to be visible within the routing instance.
Example configuration for the RIB group:
bash
set routing-options rib-groups RIB-GROUP import-rib inet.0
set routing-options rib-groups RIB-GROUP import-rib <routing-instance-name>.inet.0 This configuration ensures that routes from inet.0 are imported into the specified routing instance.
* Apply the RIB Group to the Routing Instance: Once the RIB group is configured, apply it to the appropriate routing instance:
bash
set routing-instances <routing-instance-name> routing-options rib-group RIB-GROUP
* Verify Configuration: Use the following command to verify that the static route has been imported into the routing instance:
bash
show route table <routing-instance-name>.inet.0
The output should now display the static route imported from inet.0.
Juniper Security Reference:
* RIB Groups Overview: Juniper's documentation provides detailed information on how RIB groups function and how to use them to share routes between different routing tables. This is essential for scenarios involving policy-based routing where routes from one instance (like inet.0) need to be available in another instance. Reference: Juniper Networks Documentation on RIB Groups.
By using RIB groups, you ensure that the static route from inet.0 is available in the appropriate routing instance for policy-based routing to function correctly. This avoids the need for other methods like filter- based forwarding or transparent mode, which do not address the specific issue of static route visibility across routing instances.

Answer: A,D
Explanation:
Comprehensive Detailed Step-by-Step Explanation with All Juniper Security References When two networks with overlapping IP address spaces need to communicate, Network Address Translation (NAT) is required to translate the IP addresses so that they become unique across the combined network. In this scenario, both the local network and the new branch office use the same subnet: 192.168.100.0/24. To enable communication without IP conflicts, we need to translate the overlapping addresses to unique ones.
Understanding the Problem:
* Local Network (Office A): 192.168.100.0/24
* Branch Office (Office B): 192.168.100.0/24
* Objective: Allow communication between Office A and Office B despite overlapping IP ranges.
Solution Overview:
To resolve the overlapping IP addresses, we can use Static NAT to create a one-to-one mapping between the overlapping IP addresses and a unique IP range. This way, when packets traverse the network boundary, their IP addresses are translated to a non-overlapping range, avoiding conflicts.
Option B and Option C implement Static NAT to resolve the issue:
* Option B (At Office A):
* Translates destination addresses from 192.168.200.0/24 to 192.168.100.0/24.
* This allows Office B to reach Office A's overlapping network by targeting a unique IP range (
192.168.200.0/24).
* Option C (At Office B):
* Translates destination addresses from 192.168.210.0/24 to 192.168.100.0/24.
* This allows Office A to reach Office B's overlapping network by targeting a unique IP range (
192.168.210.0/24).
Detailed Explanation:
1. Static NAT Configuration at Office A (Option B):
* Configuration:
[edit security nat static]
user@OfficeA# show rule-set From-Office-B {
from interface ge-0/0/0.0;
rule 1 {
match {
destination-address 192.168.200.0/24;
}
then {
static-nat {
prefix { 192.168.100.0/24; }
}
}
}
}
* Explanation:
* from interface ge-0/0/0.0;: Specifies the interface through which the traffic is received.
* Matching Traffic:
* destination-address 192.168.200.0/24;: Matches packets destined for 192.168.200.0/24.
* Action:
* static-nat { prefix { 192.168.100.0/24; } }: Translates the destination address to
192.168.100.0/24.
* Result:
* Office B sends packets to 192.168.200.0/24, which are translated to 192.168.100.0/24 upon arrival at Office A.

NEW QUESTION # 58
Exhibit:
Referring to the exhibit, the operator user is unable to save configuration files to a usb stick the is plugged into SRX.
What should you do to solve this problem?
- A. Add the interface-control permission flag to the operation class
- B. Add the system permission flag to the operation class
- C. Add the floppy permission flag to the operations class
- D. Add the system-control permission flag to the operation class
Answer: D
Explanation:
To solve the problem of the operator user being unable to save configuration files to a USB stick that is plugged into SRX, you need to add the system-control permission flag to the operations class.
The other options are incorrect because:
A) Adding the floppy permission flag to the operations class is not sufficient or necessary to save configuration files to a USB stick. The floppy permission flag allows the user to access the floppy drive, but not the USB drive. The USB drive is accessed by the system permission flag, which is already included in the operations class1.
C) Adding the interface-control permission flag to the operations class is also not sufficient or necessary to save configuration files to a USB stick. The interface-control permission flag allows the user to configure and monitor interfaces, but not to save configuration files. The configuration permission flag, which is also already included in the operations class, allows the user to save configuration files1.
D) Adding the system permission flag to the operations class is redundant and ineffective to save configuration files to a USB stick. The system permission flag allows the user to access the system directory, which includes the USB drive. However, the operations class already has the system permission flag by default1. The problem is not the lack of system permission, but the lack of system- control permission.
Therefore, the correct answer is B. You need to add the system-control permission flag to the operations class to solve the problem. The system-control permission flag allows the user to perform system-level operations, such as rebooting, halting, or snapshotting the device1. These operations are required to mount, unmount, and copy files to and from the USB drive2. To add the system-control permission flag to the operations class, you need to perform the following steps:
Enter the configuration mode: user@host> configure
Navigate to the system login class hierarchy: user@host# edit system login class operations Add the system-control permission flag: user@host# set permissions system-control Commit the changes: user@host# commit Reference: login (System) How to mount a USB drive on EX/SRX/MX/QFX Series platforms to import/export files
