Q48. Exhibit:

You have configured a CoS-based VPN that is not functioning correctly.
Referring to the exhibit, which action will solve the problem?

You must delete one forwarding class.

You must change the loss priorities of the forwarding classes to low.

You must use inet precedence instead of DSCP.

You must change the code point for the DB-data forwarding class to 10000.

In the exhibit, the CoS-based VPN configuration is not functioning correctly due to an issue with the number of forwarding classes. The maximum number of forwarding classes supported for CoS-based VPNs with multiple SAs (security associations) is typically four forwarding classes. In this case, more than four forwarding classes are defined.
To solve the issue, one forwarding class must be deleted to ensure that the total number of forwarding classes is reduced to four or fewer.

Q49. You are asked to create multiple virtual routers using a single SRX Series device. You must ensure that each virtual router maintains a unique copy of the routing protocol daemon (RPD) process.
Which solution will accomplish this task?

Secure wire

Tenant system

Transparent mode

Logical system

Logical systems on SRX Series devices allow the creation of separate virtual routers, each with its unique RPD process. This segmentation ensures that routing and security policies are isolated across different logical systems, effectively acting like independent routers within a single SRX device. For further information, see Juniper Logical Systems Documentation.
To create multiple virtual routers on a single SRX Series device, each with its own unique copy of the routing protocol daemon (RPD) process, you need to uselogical systems. Logical systems allow for the segmentation of an SRX device into multiple virtual routers, each with independent configurations, including routing instances, policies, and protocol daemons.
* Explanation of Answer D (Logical System):
* Alogical systemon an SRX device enables you to create multiple virtual instances of the SRX, each operating independently with its own control plane and routing processes. Each logical system gets a separate copy of the RPD process, ensuring complete isolation between virtual routers.
* This is the correct solution when you need separate routing instances with their own RPD processes on the same physical device.
Configuration Example:
bash
Copy code
set logical-systems <logical-system-name> interfaces ge-0/0/0 unit 0
set logical-systems <logical-system-name> routing-options static route 0.0.0.0/0 next-hop 192.168.1.1 Juniper Security Reference:
* Logical Systems Overview: Logical systems allow for the creation of multiple virtual instances within a single SRX device, each with its own configuration and control plane. Reference: Juniper Logical Systems Documentation.

Q50. Exhibit.

Referring to the exhibit, which two statements are true? (Choose two.)

Juniper Networks will not investigate false positives generated by this custom feed.

The custom infected hosts feed will not overwrite the Sky ATP infected host’s feed.

The custom infected hosts feed will overwrite the Sky ATP infected host’s feed.

Juniper Networks will investigate false positives generated by this custom feed.

Juniper Networks will not investigate false positives generated by this custom feed. – Typically, a vendor like Juniper Networks would not investigate false positives generated by a custom feed because the feed content is controlled by the customer, not Juniper.
The custom infected hosts feed will not overwrite the Sky ATP infected host’s feed. – Custom feeds are generally additional to the feeds provided by a vendor’s threat intelligence platform like Sky ATP. They are used to supplement the existing threat intelligence and do not overwrite it, but rather work alongside it.

Q51. Exhibit

Referring to the exhibit, which two statements are true? (Choose two.)

The SRX-1 device can use the Proxy__Nodes feed in another security policy.

You can use the Proxy_Nodes feed as the source-address and destination-address match criteria of another security policy on a different SRX Series device.

The SRX-1 device creates the Proxy_wodes feed, so it cannot use it in another security policy.

You can only use the Proxy_Node3 feed as the destination-address match criteria of another security policy on a different SRX Series device.

Q52. Exhibit

You are implementing filter-based forwarding to send traffic from the 172.25.0.0/24 network through ISP-
1 while sending all other traffic through your connection to ISP-2. Your ge-0/0/1 interface connects to two networks, including the 172.25.0.0/24 network. You have implemented the configuration shown in the exhibit. The traffic from the 172.25.0.0/24 network is being forwarded as expected to 172.20.0.2, however traffic from the other network (172.25.1.0/24) is not being forwarded to the upstream 172.21.0.2 neighbor.
In this scenario, which action will solve this problem?

You must specify that the 172.25.1.1/24 IP address is the primary address on the ge-0/0/1 interface.

You must apply the firewall filter to the lo0 interface when using filter-based forwarding.

You must add another term to the firewall filter to accept the traffic from the 172.25.1.0/24 network.

You must create the static default route to neighbor 172.21 0.2 under the ISP-1 routing instance hierarchy.

Q53. Referring to the exhibit,

which two statements are correct about the NAT configuration? (Choose two.)

Both the internal and the external host can initiate a session after the initial translation.

Only a specific host can initiate a session to the reflexive address after the initial session.

Any external host will be able to initiate a session to the reflexive address.

The original destination port is used for the source port for the session.

Explanation:

Q54. Exhibit:

You have deployed an SRX Series device as shown in the exhibit. The devices in the Local zone have recently been added, but their SRX interfaces have not been configured. You must configure the SRX to meet the following requirements:
* Devices in the 10.1.1.0/24 network can communicate with other devices in the same network but not with other networks or the SRX.
* You must be able to apply security policies to traffic flows between devices in the Local zone.
Which three configuration elements will be required as part of your configuration? (Choose three.)

set security zones security-zone Local interfaces ge-0/0/1.0

set interfaces ge-0/0/1 unit 0 family ethernet-switching vlan-members 10

set protocols l2-learning global-mode switching

set protocols l2-learning global-mode transparent-bridge

set security zones security-zone Local interfaces irb.10

In this scenario, we need to configure the SRX Series device so that devices in the Local zone (VLAN 10,
10.1.1.0/24 network) can communicate with each other but not with other networks or the SRX itself.
Additionally, you must be able to apply security policies to traffic flows between the devices in the Local zone.
* Explanation of Answer A (Assigning Interface to Security Zone):
* You need to assign the interface ge-0/0/1.0 to the Local security zone. This is crucial because the SRX only applies security policies to interfaces assigned to security zones. Without this, traffic between devices in the Local zone won’t be processed by security policies.
* Configuration:
set security zones security-zone Local interfaces ge-0/0/1.0
* Explanation of Answer B (Configuring Ethernet-Switching for VLAN 10):
* Since we are using Layer 2 switching between devices in VLAN 10, we need to configure the interface to operate in Ethernet switching mode and assign it to VLAN 10.
* Configuration:
set interfaces ge-0/0/1 unit 0 family ethernet-switching vlan-members 10
* Explanation of Answer D (Transparent Bridging Mode for Layer 2):
* The global mode for Layer 2 switching on the SRX device must be set to transparent-bridge.
This ensures that the SRX operates in Layer 2 mode and can switch traffic between devices without routing.
* Configuration:
set protocols l2-learning global-mode transparent-bridge
Summary:
* Interface Assignment: Interface ge-0/0/1.0 is assigned to the Local zone to allow policy enforcement.
* Ethernet-Switching: The interface is configured for Layer 2 Ethernet switching in VLAN 10.
* Transparent Bridging: The SRX is configured in Layer 2 transparent-bridge mode for switching between devices.
Juniper Security Reference:
* Layer 2 Bridging and Switching Overview: This mode allows the SRX to act as a Layer 2 switch for forwarding traffic between VLAN members without routing. Reference: Juniper Transparent Bridging Documentation.

Q55. Exhibit

You are implementing filter-based forwarding to send traffic from the 172.25.0.0/24 network through ISP-
1 while sending all other traffic through your connection to ISP-2. Your ge-0/0/1 interface connects to two networks, including the 172.25.0.0/24 network. You have implemented the configuration shown in the exhibit. The traffic from the 172.25.0.0/24 network is being forwarded as expected to 172.20.0.2, however traffic from the other network (172.25.1.0/24) is not being forwarded to the upstream 172.21.0.2 neighbor.
In this scenario, which action will solve this problem?

You must specify that the 172.25.1.1/24 IP address is the primary address on the ge-0/0/1 interface.

You must apply the firewall filter to the lo0 interface when using filter-based forwarding.

You must add another term to the firewall filter to accept the traffic from the 172.25.1.0/24 network.

You must create the static default route to neighbor 172.21 0.2 under the ISP-1 routing instance hierarchy.

Q56. You are deploying IPsec VPNs to securely connect several enterprise sites with ospf for dynamic routing. Some of these sites are secured by third-party devices not running Junos.
Which two statements are true for this deployment? (Choose two.)

OSPF over IPsec can be used for intersite dynamic routing.

Sites with overlapping address spaces can be supported.

OSPF over GRE over IPsec is required to enable intersite dynamic routing

Sites with overlapping address spaces cannot be supported.

Understanding the Scenario:
* Objective: Deploy IPsec VPNs connecting multiple enterprise sites using OSPF for dynamic routing.
* Challenge: Some sites use third-party devices not running Junos OS.
* Considerations:
* Compatibility between Juniper and third-party devices.
* Support for dynamic routing protocols (OSPF) over IPsec VPNs.
* Handling overlapping IP address spaces.
Option Analysis:
Option A: OSPF over IPsec can be used for intersite dynamic routing.
* Explanation:
* OSPF Characteristics:
* OSPF uses multicast addresses (224.0.0.5 and 224.0.0.6) for neighbor discovery and routing updates.
* IPsec Limitations:
* Standard IPsec tunnel mode does not support multicast traffic natively.
* Multicast traffic cannot traverse IPsec tunnels unless encapsulated.
* Juniper Solution:
* Juniper devices can use routed VPNs (route-based VPNs) with st0 interfaces, allowing OSPF over IPsec.
* However, this requires support from both ends of the VPN tunnel.
* Third-Party Devices:
* May not support OSPF over IPsec without additional configurations.
* Conclusion:
* Option A is not universally true in this scenario due to third-party device limitations.

Q57. You are asked to set up advanced policy-based routing.
Which type of routing instance is designed to support this scenario?

forwarding

virtual switch

virtual router

non-forwarding

Comprehensive Detailed Step-by-Step Explanation with All Juniper Security References Understanding Advanced Policy-Based Routing (APBR):
* APBR: Allows routing decisions based on application-level information and policies.
* Objective: Direct specific application traffic through different paths based on policies.
Routing Instances in Junos OS:
* Forwarding Instance:
* Used for features like filter-based forwarding (FBF) and APBR.
* Provides a separate forwarding table but shares the global routing table.
* Supports APBR.
* Virtual Router:
* Provides a separate routing table and forwarding table.
* Used for logical separation of routing domains.
* Does not support APBR directly.
* Virtual Switch:
* Operates at Layer 2.
* Used for VLAN separation and Layer 2 switching.
* Not applicable to routing or APBR.
* Non-Forwarding Instance:
* Used for management purposes.
* Does not forward transit traffic.
* Not suitable for APBR.
* Option A: forwarding
* Correct.
* A forwarding routing instance is specifically designed to support advanced policy-based routing.
* It allows the SRX device to direct traffic based on policies to different forwarding instances.

Q58. Exhibit:

Referring to the exhibit, which statement is true?

SRG1 is configured in hybrid mode.

The ICL is encrypted.

If SRG1 moves to peer 2, peer 1 will drop packets sent to the SRG1 interfaces.

If SRG1 moves to peer 2, peer 1 will forward packets sent to the SRG1 interfaces.

The exhibit describes aChassis Clusterconfiguration with high availability (HA) settings. The key information is related toService Redundancy Group 1 (SRG1)and its failover behavior between the two peers.
* Explanation of Answer D (Packet Forwarding after Failover):
* In a typical SRX HA setup withactive/backup configuration, if theSRG1group moves topeer 2 (the backup),peer 1(previously the active node) will forward packets topeer 2instead of dropping them. This ensures smooth failover and seamless continuation of services without packet loss.
* This behavior is part of the active/backup failover process in SRX chassis clusters, where the standby peer takes over traffic processing without disruption.
Juniper Security Reference:
* Chassis Cluster Failover Behavior: When a service redundancy group fails over to the backup peer, the previously active peer forwards traffic to the new active node. Reference: Juniper Chassis Cluster Documentation.

Q59. your company wants to take your juniper ATP appliance into private mode. You must give them a list of impacted features for this request.
Which two features are impacted in this scenario? (Choose two)

False Positive Reporting

Threat Progression Monitoring

GSS Telemetry

Cyber Kill Chain mapping

Your company wants to take your Juniper ATP Appliance into private mode. You must give them a list of impacted features for this request.
The two features that are impacted in this scenario are:
A) False Positive Reporting. False Positive Reporting is a feature that allows you to report false positive detections to Juniper Networks for analysis and improvement. False Positive Reporting requires an Internet connection to send the reports to Juniper Networks. If you take your Juniper ATP Appliance into private mode, False Positive Reporting will be disabled and you will not be able to report false positives1.
C) GSS Telemetry. GSS Telemetry is a feature that allows you to send anonymized threat data to Juniper Networks for analysis and improvement. GSS Telemetry requires an Internet connection to send the data to Juniper Networks. If you take your Juniper ATP Appliance into private mode, GSS Telemetry will be disabled and you will not be able to contribute to the threat intelligence community2.
The other options are incorrect because:
B) Threat Progression Monitoring. Threat Progression Monitoring is a feature that allows you to monitor the threat activity and progression across your network. Threat Progression Monitoring does not require an Internet connection and can be performed locally by the Juniper ATP Appliance. If you take your Juniper ATP Appliance into private mode, Threat Progression Monitoring will not be impacted and you will still be able to monitor the threat activity and progression3.
D) Cyber Kill Chain mapping. Cyber Kill Chain mapping is a feature that allows you to map the threat activity and progression to the stages of the Cyber Kill Chain framework. Cyber Kill Chain mapping does not require an Internet connection and can be performed locally by the Juniper ATP Appliance. If you take your Juniper ATP Appliance into private mode, Cyber Kill Chain mapping will not be impacted and you will still be able to map the threat activity and progression4.

Threat Progression Monitoring Cyber Kill Chain Mapping

Q60. you are connecting two remote sites to your corporate headquarters site. You must ensure that traffic passes corporate headquarter.

In this scenario, which VPN should be used?

full mesh IPsec VPNs with tunnels between all sites

a full mesh Layer 3 VPN with the BGP route reflector behind the corporate firewall device

a Layer 3 VPN with the corporate firewall acting as the hub device

hub-and-spoke IPsec VPN with the corporate firewall acting as the hub device

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.

Q61. Exhibit

An administrator wants to configure an SRX Series device to log binary security events for tenant systems.
Referring to the exhibit, which statement would complete the configuration?

Configure the tenant as TSYS1 for the pi security profile.

Configure the tenant as root for the pi security profile.

Configure the tenant as master for the pi security profile.

Configure the tenant as local for the pi security profile

Q62. Exhibit

Referring to the exhibit, which two statements are true? (Choose two.)

The 3uspicious_Endpoint3 feed is only usable by the SRX-1 device.

You must manually create the suspicious_Endpoint3 feed in the Juniper ATP Cloud interface.

The 3uspiciou3_Endpoint3 feed is usable by any SRX Series device that is a part of the same realm as SRX-1

Juniper ATP Cloud automatically creates the 3uopi’cioua_Endpoints feed after you commit the security policy.

Q63. You need to set up source NAT so that external hosts can initiate connections to an internal device, but only if a connection to the device was first initiated by the internal device.
Which type of NAT solution provides this functionality?

Address persistence

Persistent NAT with any remote host

Persistent NAT with target host

Static NAT

Persistent NAT with target host allows external hosts to establish connections only when the internal device initiates a session first, ideal for specific interactive applications. Refer to Juniper Persistent NAT Documentation.
The scenario requires that external hosts be able to initiate a connectiononly if the internal device has already initiated a connection. The correct solution isPersistent NAT with target host, which ensures that a specific external host can initiate new connections back to the internal device, but only after the internal device has established a session first.
* Persistent NAT with Target Host (Answer C): This allows the internal device to initiate a connection, and once established, the specified external host can also initiate new connections to the internal device on the same NAT mapping.
Example Configuration:
bash
Copy code
set security nat source persistent-nat permit target-host-port
This solution is appropriate when controlled bidirectional communication is required based on an internal- initiated connection.

Q64. You want to enforce I DP policies on HTTP traffic.
In this scenario, which two actions must be performed on your SRX Series device? (Choose two)

Choose an attacks type in the predefined-attacks-group HTTP-All.

Disable screen options on the Untrust zone.

Specify an action of None.

Match on application junos-http.
