NEW QUESTION # 59
You want to configure the SSL proxy feature on your SRX Series Firewall.
Which two actions must you perform to accomplish this task? (Choose two.)
Answer: A,D
Explanation:
The correct answers are B and D. On SRX Series Firewalls, SSL proxy is configured by creating an SSL proxy profile and then applying that profile to the relevant security policy as an application service. Juniper's SSL proxy configuration overview lists the required workflow: configure certificates and CA profile material, configure the SSL proxy profile, create a security policy matching the traffic to be inspected, and apply the SSL proxy profile to that security policy. Juniper further states that SSL proxy is enabled as an application service within a security policy, where the policy match criteria identify the traffic and the SSL proxy profile is applied to that traffic.
Option A is wrong because enabling the SSL ALG is not the required control point for SSL proxy. SSL proxy is a decryption/inspection service applied through policy, not simply an ALG toggle. Option C is wrong because creating a separate SSL application object is not the mandatory SSL proxy configuration action. The policy can match the desired traffic and then invoke SSL proxy through then permit application-services ssl- proxy profile-name. Juniper's example explicitly shows applying the SSL proxy profile under the security policy action.
Reference topics: SSL Proxy, SSL forward proxy, SSL proxy profiles, security policy application-services, encrypted traffic inspection.
NEW QUESTION # 60
You need to secure communications from a mobile command center which uses a 5G mobile ISP behind CGNAT to an SRX Series Firewall at headquarters.
Which two actions should be performed on the SRX Series Firewall in this scenario? (Choose two.)
Answer: A,B
Explanation:
The correct answers are A and D. A mobile command center using a 5G ISP behind CGNAT is operating behind dynamic address translation. For IPsec to work reliably through NAT, the SRX must support NAT Traversal, which encapsulates IKE and ESP traffic in UDP/4500 after NAT is detected. Juniper states that NAT-T is used when NAT devices exist in the datapath and that NAT keepalives are required because NAT devices age out UDP translations. Juniper's Security Director VPN workflow also specifically says to enable NAT-T when the dynamic endpoint is behind a NAT device.
DPD is also required because mobile and carrier-grade NAT connections can disappear, roam, or become stale without a clean tunnel teardown. Juniper defines Dead Peer Detection as the method used by IPsec peers to verify whether the remote peer is still present and responsive by sending encrypted IKE notification payloads and waiting for acknowledgements. Option B is not the best answer because IKEv1 aggressive mode is weaker and does not provide identity protection; Juniper also notes that aggressive mode applies only to IKEv1. Option C is invalid because IKEv2 aggressive mode does not exist. Reference topics: IPsec VPN, NAT-T, CGNAT, dynamic endpoints, DPD, IKE peer availability.
NEW QUESTION # 61
What does the exhibit indicate when you have configured a single IPsec VPN on an SRX Series Firewall?
Answer: D
Explanation:
The correct answer is B. The IPsec VPN is established, and traffic is passing through . The exhibit shows nonzero ESP encrypted bytes , ESP decrypted bytes , encrypted packets , and decrypted packets . On an SRX Series Firewall, those counters indicate that the device is both encrypting outbound traffic into the IPsec tunnel and decrypting inbound ESP traffic from the remote peer. Juniper's show security ipsec statistics reference identifies ESP statistics as the counters for encrypted/decrypted bytes and packets, and Juniper troubleshooting guidance states that incrementing encrypted and decrypted packet counters confirm traffic flow across the VPN.
Option A is wrong because the error counters show AH authentication failures: 0, Replay errors: 0, ESP authentication failures: 0, ESP decryption failures: 0, Bad headers: 0, and Bad trailers: 0. Option C is wrong because encrypted and decrypted ESP packet counters would not increment if the IPsec tunnel were not established. Option D is wrong because traffic is clearly passing; the nonzero ESP counters prove packet movement through the tunnel. Reference topics: IPsec VPN, ESP statistics, encrypted/decrypted counters, tunnel verification, IPsec troubleshooting.
NEW QUESTION # 62
Using Junos Space Security Director, you want to configure a unique firewall policy for a specific SRX Series device.
Which firewall policy rules would satisfy the requirement?
Answer: C
Explanation:
The correct answer is C. device policy rules. In Junos Space Security Director, policy scope matters. A rule intended for one specific SRX Series device must be placed in a device policy, because Juniper defines a device policy as a firewall policy created per device and used when you want to push a unique firewall policy configuration per device. Security Director also distinguishes this from group policies, which are shared with multiple devices, and from all-devices policy rules, which are global in scope rather than device-specific.
Option A is wrong because all-devices prerules are global rules evaluated before device-specific rules; they are not intended for a unique single-device exception. Option B is wrong because group policy prerules apply to devices within a group, not to one individually targeted SRX firewall. Option D is wrong because all- devices postrules are still globally scoped, even though they occur later in policy order. The clean Security Director design is to use device policy rules when the policy must apply only to one SRX device. Reference topics: Security Director, firewall policy hierarchy, device policy, group policy, all-devices prerules/postrules.
NEW QUESTION # 63
You have configured a new site-to-site VPN tunnel. The exhibit shows the security IPsec statistics output for the specific tunnel index from one of the tunnel-end devices.
Which two statements are correct in this scenario? (Choose two.)
Answer: B,C
Explanation:
The correct answers are C and D. The exhibit shows ESP encrypted bytes = 0, ESP decrypted bytes = 0, encrypted packets = 0, and decrypted packets = 0. That means no traffic is successfully passing through the IPsec tunnel. Juniper's show security ipsec statistics command displays ESP encrypted/decrypted packet and byte counters, so zero values on these counters indicate that the tunnel is not successfully carrying protected ESP traffic.
Option C is also correct because the output shows ESP authentication failures and ESP decryption failures.
Since ESP is the IPsec protocol responsible for encrypted payload handling, failures in ESP authentication
/decryption point to an ESP/IPsec Phase 2 mismatch or incorrect configuration, such as mismatched authentication algorithm, encryption algorithm, keys, proposal parameters, or incompatible negotiated SA settings. Juniper's IPsec overview explains that Phase 2 negotiates the IPsec SA used to authenticate traffic flowing through the tunnel, so ESP-related failures belong to the IPsec/ESP configuration path rather than AH.
Option A is wrong because the AH counters and AH authentication failures are zero; the evidence is not pointing to AH. Option B is unsupported because the output does not show peer reboot behavior. Reference topics: IPsec VPN, ESP statistics, Phase 2/IPsec SA negotiation, ESP authentication failures, ESP decryption failures.
