Configure the same static routes on both devices to ensure proper traffic flow.
Implement a default permit rule for all traffic in the security policies to allow VPN traffic.
Set up a dynamic routing protocol to automatically manage tunnel traffic.
Ensure both devices have matching IKE and IPsec settings, including encryption algorithms and lifetimes.

Explanation: Ensuring that both devices have matching IKE and IPsec settings, including encryption algorithms and lifetimes, is critical for establishing a secure and functional Site-to-Site VPN.

Quest

Source NAT is used primarily for internal hosts to communicate with external networks.
Destination NAT is used to allow external hosts to initiate connections to internal services.
Both source and destination NAT can be configured simultaneously for the same traffic flow.
Source NAT modifies the destination address of packets leaving the network. Answer: A, B

Explanation: Source NAT is primarily used for allowing internal hosts to communicate with external networks, while destination NAT enables external hosts to connect to services hosted internally, facilitating bidirectional communication.

Question: 679

In the context of an application firewall, why is it important to implement application-layer filtering in addition to traditional network-layer filtering?

Traditional filtering is sufficient to protect against all types of attacks.
Application-layer filtering addresses threats that exploit vulnerabilities specific to applications, which network-layer filtering cannot adequately mitigate.
implifies the configuration of firewall rules.

er: B

nation: Application-layer filtering is crucial because it addresses threats that target specific ation vulnerabilities, which traditional network-layer filtering alone cannot adequately mitiga roviding a more comprehensive security approach.

Question: 681

Which two aspects of the vSRX deployment make it suitable for cloud environments? (Choose two.)

It requires dedicated physical hardware for optimal performance.
It can scale vertically by increasing resources on a single instance.
The vSRX can be deployed on various hypervisors, enhancing flexibility.
It is limited to specific cloud providers for deployment. Answer: B, C

Explanation: The vSRX can scale vertically by increasing resources on a single instance, making it adaptable to varying loads. It also supports deployment on various hypervisors, providing flexibility in cloud environments.

ontext of Juniper's advanced threat prevention capabilities, which two features are critical f ng and mitigating malware and zero-day threats? (Choose two.)

plication Layer Gateways (ALGs) that modify application traffic in real-time.

egrated intrusion detection and prevention systems (IDPS) that analyze traffic patterns. tic signature databases that exclusively rely on known malware definitions.

havioral analysis tools that monitor for anomalous activities across the network. er: B, D

nation: Advanced threat prevention mechanisms rely on integrated intrusion detection and tion systems (IDPS) to analyze traffic patterns and behavioral analysis tools to identify ano ies, thus effectively detecting and mitigating malware and zero-day threats.

Question: 684

Which command would you use to verify the active security policies applied to an interface on a Juniper

SRX device, ensuring that you are examining the correct zone configuration?

show interfaces security
show configuration security policies
show security policies from-zone to-zone
show security zones

security policies applied between defined zones, providing clarity on how traffic is managed based security configuration.

two statements about Juniper's device hardening techniques are essential for mitigating pote abilities and securing the SRX devices? (Choose two.)

abling unnecessary services and protocols to reduce the attack surface. eping the default administrative credentials to simplify future access.

gularly updating the device firmware and software to patch known vulnerabilities. owing unrestricted access to management interfaces from any IP address.

nation: Device hardening techniques include disabling unnecessary services and protocols to ize the attack surface, as well as regularly updating firmware and software to patch known abilities, ensuring the security of SRX devices.
