NEW QUESTION # 65
You have created a series of security policies permitting access to a variety of services. You now want to create a policy that blocks access to all other services for all user groups.
What should you create in this scenario?
- A. integrated user firewall policy
- B. Juniper ATP policy
- C. IDP policy
- D. global security policy
Answer: D
Explanation:
To enforce a catch-all blocking policy after other specific policies, the correct solution is a global security policy (Option A).
Global policies can apply universally across zones, and an administrator can configure a final "deny all" rule to block any unmatched traffic.
ATP policy (Option B): Protects against advanced threats, not used for catch-all rule enforcement.
IDP policy (Option C): Focuses on intrusion detection and prevention signatures, not general traffic blocking.
Integrated user firewall policy (Option D): Applies policies based on user identity, but it does not provide a universal block across all services.
Correct Solution: Global security policy
NEW QUESTION # 66
What must also be enabled when using source NAT if the address pool is in the same subnet as the interface?
- A. destination NAT
- B. static NAT
- C. proxy ARP
- D. dynamic DNS
Answer: C
Explanation:
When the source NAT address pool belongs to the same subnet as the egress interface, the SRX must respond to ARP requests for those translated IPs. Enabling proxy ARP allows the firewall to reply on behalf of those NAT pool addresses, ensuring proper packet delivery.
NEW QUESTION # 67
You want to enable NextGen Web Filtering in SRX Series devices.
In this scenario, which two actions will accomplish this task? (Choose two.)
- A. Configure an SSL initiation profile.
- B. Generate a self-signed certificate.
- C. Configure an SSL proxy profile.
- D. Generate a CA-signed certificate.
Answer: B,C
Explanation:
NextGen Web Filtering (NGWF) requires SSL proxy functionality to inspect HTTPS traffic. To enable NGWF:
Option B: You can generate a self-signed certificate for SSL proxy functionality (or import a CA-signed certificate, but the course emphasizes self-signed for lab/demo purposes).
Option D: You must configure an SSL proxy profile so that HTTPS traffic can be decrypted and inspected.
Option A: A CA-signed certificate may be used in production but is not strictly required to enable NGWF.
Option C: SSL initiation profiles are used for outbound SSL inspection initiated by the SRX, not for NGWF traffic interception.
Correct Actions: Generate a self-signed certificate, Configure an SSL proxy profile
NEW QUESTION # 68
Which two characteristics of destination NAT and static NAT are correct? (Choose two.)
- A. Static NAT automatically creates a matching rule for the opposite direction.
- B. Destination NAT supports port forwarding.
- C. Static NAT uses Port Address Translation.
- D. Destination NAT requires address range sizes that match the devices being translated.
Answer: A,B
Explanation:
* Static NAT:Provides a one-to-one bidirectional mapping between internal and external IP addresses.
When configured, the translation automatically applies in both directions (Option A is correct). It does not use Port Address Translation (Option C is incorrect).
* Destination NAT:Allows external clients to access internal resources by translating the destination address. It supportsport forwardingso specific services (e.g., HTTP on port 80) can be forwarded to an internal host (Option D is correct). It does not require equal-sized address ranges (Option B is incorrect).
Correct Characteristics:Static NAT is bidirectional, and Destination NAT supports port forwarding.

NEW QUESTION # 69
You just made a configuration change to a security policy on your SRX Series Firewall. Your users alert you that an application that uses FTP is no longer working.
Referring to the exhibit, what are two ways to solve this problem? (Choose two.)
- A. Insert the FTP security policy before the web-smtp security policy.
- B. Enter the rollback 1 command followed by a commit command.
- C. Change the destination address in the FTP security policy to any and commit the configuration.
- D. Activate the FTP security policy and commit the configuration.
Answer: B,D
Explanation:
The exhibit shows that the FTP policy is marked inactive, so it remains in the configuration but does not take effect when the configuration is committed. Juniper documentation explains that inactive configuration elements are ignored and are not applied during commit. One valid fix is to activate the FTP policy and commit the configuration so that the policy becomes active again. Another valid fix is to use rollback 1 to return to the previously committed configuration, then commit that restored configuration. Simply moving the inactive FTP policy before another policy would not help because an inactive policy is still ignored. Changing the destination address to any is unnecessary because the primary problem shown is the inactive FTP policy.
NEW QUESTION # 70
You want to confirm that your SRX Series Firewall is connected to the SBL server.
Which operational mode command would you use in this scenario?
- A. show security utm anti-spam status
- B. show security utm content-filtering statistics
- C. show security utm anti-virus status
- D. show security web filtering status
Answer: A
Explanation:
The anti-spam status command displays connectivity and status information for the Spam Block List (SBL) server, allowing you to verify that the SRX Series Firewall is properly connected to it.
NEW QUESTION # 71
Which statement about the flow module is correct in the context of destination NAT?
- A. The flow module performs NAT only during first path processing.
- B. The flow module performs NAT during both first path and fast path processing.
- C. The flow module performs NAT only for source IP addresses.
- D. The flow module performs NAT only during fast path processing.
Answer: B
Explanation:
In SRX flow-based processing, the first packet of a new session goes through first path processing, where NAT rule lookup, route lookup, security policy evaluation, and session creation occur. Destination NAT is performed before security policy evaluation, so the translated destination address is used when matching the policy. After the session is created, later packets use fast path processing and follow the cached session information, including the NAT translation state created for the session. Therefore, the flow module is involved with NAT behavior in both first path and fast path processing. Option B is incorrect because destination NAT changes destination addresses, not only source addresses. Options C and D are incomplete because NAT lookup and session installation occur during first path, while established NAT translations are applied during fast path.
NEW QUESTION # 72
You want to verify the peer before IPsec tunnel establishment.
What would be used as a final check in this scenario?
- A. proxy ID
- B. traffic selector
- C. perfect forward secrecy
- D. st0 interfaces
Answer: A
Explanation:
The proxy ID is used as a final check to verify the peer before IPsec tunnel establishment. The proxy ID is a combination of local and remote subnet and protocol, and it is used to match the traffic that is to be encrypted. If the proxy IDs match between the two IPsec peers, the IPsec tunnel is established, and the traffic is encrypted.
NEW QUESTION # 73
Which type of policy is shown in the exhibit?
- A. inter-zone policy
- B. default policy
- C. global policy
- D. intra-zone policy
Answer: D
Explanation:
The policy is defined from-zone Trust to-zone Trust, which means traffic is controlled within the same security zone, making it an intra-zone policy.
NEW QUESTION # 74
Which UI enables you to manage, monitor, and maintain multiple firewalls using a single interface?
- A. Security Director
- B. Juniper Secure Analytics
- C. Secure Connect
- D. Juniper Identity Management Service
Answer: A
Explanation:
* Security Director (Option B):A Junos Space application that provides a centralized interface for managing, monitoring, and maintaining multiple SRX firewalls.
* Juniper Secure Analytics (Option A):Focuses on SIEM/log analysis, not centralized firewall management.
* Identity Management Service (Option C):Provides user identity integration for policy enforcement, not a management UI.
* Secure Connect (Option D):A VPN client solution, not a firewall management platform.
Correct UI:Security Director

NEW QUESTION # 75
You are asked to create a security policy that controls traffic allowed to pass between the Internet and private security zones. You must ensure that this policy is evaluated before all other policy types on your SRX Series device.
In this scenario, which type of security policy should you create?
- A. global policy
- B. default policy
- C. zone policy
- D. routing policy
Answer: A
Explanation:
Global policies (Option D): Evaluated before zone-based policies. They allow centralized control and can apply across all zones. Perfect for Internet-to-private traffic that must be enforced before other rules.
Routing policy (Option A): Controls routing decisions, not traffic forwarding/security.
Default policy (Option B): Denies all traffic by default, but cannot be customized for early evaluation.
Zone policy (Option C): Zone-based policies apply after global policies and are limited to specific zone pairs.
Correct Policy Type: Global policy
NEW QUESTION # 76
You are not able to ping an interface on an SRX Series Firewall.
Which two actions should you take to solve this issue? (Choose two.)
- A. Assign the interface to a security zone.
- B. Create a security policy to allow ping traffic.
- C. Assign the interface to the null zone.
- D. Configure the ICMP protocol for host-inbound-traffic.
Answer: A,D
Explanation:
For an SRX firewall interface to respond to management traffic such as ICMP pings:
* Theinterface must be assigned to a security zone(Option A). If an interface is not part of any zone, it is placed into the null zone, which drops all traffic.
* Additionally, the zone must be configured to allow management traffic types ashost-inbound-traffic (Option D). For ICMP, the protocol must be explicitly allowed under host-inbound-traffic for that zone.
Other options:
* Security policies (Option B) control traffic traversing the firewall, not traffic destined to the SRX device itself.
* Assigning the interface to the null zone (Option C) prevents any communication, including management.
Correct Actions:Assign the interface to a zone and configure ICMP under host-inbound-traffic.

NEW QUESTION # 77
You just made a configuration change to a security policy on your SRX Series Firewall. Your users alert you that an application that uses FTP is no longer working.
Referring to the exhibit, what are two ways to solve this problem? (Choose two.)
- A. Insert the ftpsecurity policy before the web-smtpsecurity policy.
- B. Enter the rollback 1command followed by a commitcommand.
- C. Change the destination address in the ftpsecurity policy to anyand commit the configuration.
- D. Activate the ftpsecurity policy and commit the configuration.
Answer: B,D
Explanation:
Rolling back one commit (rollback 1) and committing restores the previous working configuration where the FTP policy was active and functioning correctly.
The ftp policy is marked as inactive, which prevents it from being enforced. Activating it and committing the configuration will re-enable FTP traffic to Server-1, restoring service functionality.
NEW QUESTION # 78
What must also be enabled when using source NAT if the address pool is in the same subnet as the interface?
- A. destination NAT
- B. static NAT
- C. proxy ARP
- D. dynamic DNS
Answer: C
Explanation:
When source NAT uses a pool of addresses from the same subnet as the egress interface, the firewall must respond to ARP requests for those NAT pool IPs. Without this, upstream devices would not know how to forward traffic destined for those IPs.
Proxy ARP is required (Option D). It enables the SRX to answer ARP requests on behalf of the NAT pool addresses.
Static NAT (Option A) is unrelated and maps one-to-one, not required here.
Dynamic DNS (Option B) has no relation to NAT pools.
Destination NAT (Option C) applies to inbound translations, not outbound source NAT pools.
Correct Feature: Proxy ARP
NEW QUESTION # 79

- A. Assign the interface to a security zone.
- B. Create a security policy to allow ping traffic.
- C. Assign the interface to the null zone.
- D. Configure the ICMP protocol for host-inbound-traffic.
Answer: A,D
Explanation:
For an SRX firewall interface to respond to management traffic such as ICMP pings:
The interface must be assigned to a security zone (Option A). If an interface is not part of any zone, it is placed into the null zone, which drops all traffic.
Additionally, the zone must be configured to allow management traffic types as host-inbound-traffic (Option D). For ICMP, the protocol must be explicitly allowed under host-inbound-traffic for that zone.
Other options:
Security policies (Option B) control traffic traversing the firewall, not traffic destined to the SRX device itself.
Assigning the interface to the null zone (Option C) prevents any communication, including management.
Correct Actions: Assign the interface to a zone and configure ICMP under host-inbound-traffic.
