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.

The correct answers are A and C. To use user identity information on an SRX Series Firewall, the firewall must first be able to obtain identity mappings from an identity source or identity provider, such as Active Directory, JIMS, Aruba ClearPass, or another supported identity-aware firewall component. Juniper’s identity-aware firewall documentation states that identity parameters are used to configure security policies so authenticated users receive the correct level of access, and that firewalls can query JIMS, obtain user identity information, and then enforce security policy decisions.

Option A is required because identity-aware enforcement only happens when security policies include user identity match criteria, such as source identity, users, roles, or groups. Juniper’s source-identity policy reference states that source identities are used as match criteria in security policies, and when configured, traffic is matched against authentication-table entries before policy lookup completes. Option C is required because the SRX must be configured with an identity source/provider so it can populate or query identity mappings. Option B is not an SRX configuration task and is not generally required because users may already exist in appropriate AD groups. Option D is wrong for this question; the required SRX tasks are configuring identity integration and identity-aware policies, not adding a separate “user identity” license. Reference topics: Identity-Aware Security Policies, identity source/provider, authentication table, source-identity policy matching.

The correct answers are B and C. The exhibit shows the command request security idp security-package install failing with: “Security package installation disabled temporarily due to invalid license.” In the IDP update workflow, the SRX must have a valid IDP/AppSecure-related license to install updated security packages. Juniper’s support guidance for an expired IDP license states that if the IDP license expires, attacks continue to be inspected, but IDP update installation is not allowed. That maps directly to this exhibit: the existing IDP engine and currently installed attack database can continue to inspect traffic, but the device cannot install the newer downloaded package until licensing is corrected.

Option A is wrong because expiration does not immediately stop all IDP inspection; it prevents installing new updates. Option D is not the best answer because the specific operational behavior shown is consistent with an invalid/expired license condition after attempting a package install, not proof that no license was ever installed. The practical remediation is to validate the installed license, renew or reinstall the correct IDP license, then retry the security-package installation. Reference topics: IDP licensing, security-package download/install, attack database updates, installed signature inspection behavior.

The correct answers are A and D. In IKEv1-based IPsec VPNs, there are two distinct negotiation phases. IKEv1 Phase 1 establishes the secure and authenticated IKE channel between peers. That means the IKE SA is built during Phase 1. Juniper describes Phase 1 as the negotiation of proposals for how to authenticate and secure the channel, including encryption algorithms, authentication algorithms, Diffie-Hellman group, and authentication method.

IKEv1 Phase 2 then uses that secure channel to negotiate the IPsec SAs that protect actual user traffic through the VPN. Juniper states that Phase 2 negotiates security associations to secure the data traversing the IPsec tunnel, and that the Phase 2 proposal includes the security protocol, such as ESP or AH, plus the selected encryption and authentication algorithms. Option B is wrong because IKEv1 SAs are not established in Phase 2; Phase 2 creates IPsec SAs. Option C is wrong because Phase 1 does not create the data-plane IPsec SA; it creates the secure IKE control channel used for Phase 2 negotiation. Reference topics: IPsec VPN, IKEv1 Phase 1, IKE SA, IKEv1 Phase 2, IPsec SA, ESP/AH proposals.

The correct answers are A and D. Juniper provides predefined IDP policy templates to simplify IDP deployment. These templates are supplied by Juniper Networks and include common templates such as client protection, server protection, DMZ services, DNS server, file server, web server, IDP default, and recommended policies. Juniper’s IDP documentation states that predefined templates are available from a secured Juniper Networks website, and the listed templates are explicitly described as being provided by Juniper Networks.

Option D is correct because these templates are not automatically present as usable policies in a factory-default SRX configuration. Juniper’s procedure says that to use predefined IDP policy templates, you download the policy templates and then install them. The CLI process includes request security idp security-package download policy-templates followed by request security idp security-package install policy-templates; committing then makes them available under the IDP policy hierarchy.

Option B is wrong because Juniper specifically says you should customize these templates for your network and recommends using a copied template so you can safely make changes. Option C is wrong because they must be downloaded and installed, so they are not simply available in the factory-default configuration. Reference topics: IDP, predefined IDP policy templates, security-package download, security-package install, active IDP policy.

The correct answers are B and D. The command output is from the SRX Series device: show services user-identification identity-management status. Under Primary server, the exhibit shows Address: 192.168.1.10, Port: 443, Connection method: HTTPS, and Connection status: Online. In Juniper Identity Management Service integration, the SRX is the client that connects to the configured primary JIMS server. Juniper’s configuration workflow specifically describes configuring “the IP address of the primary JIMS server” under services user-identification identity-management connection primary address, and the verification output shows that primary server address with its connection status.

Option A is wrong because 192.168.1.10 is listed under Primary server, not as the local SRX address. Option C is also wrong because this SRX command verifies the SRX-to-JIMS identity-management connection, not the backend JIMS-to-domain-controller connection. Domain controller reachability would be validated from JIMS or through JIMS-specific status/monitoring, not by this SRX-side output. The displayed Online state and OK (200) status confirm that the SRX successfully reached the JIMS HTTPS service and received a valid response. Juniper examples use the same status command to validate that the SRX identity-management connection to JIMS is online.

The correct answer is D. drop packet. In IDP terminology, a silent discard means the offending packet is discarded without sending reset packets or other connection-closing signals back to the endpoints. Juniper defines the Drop Packet IDP action as dropping a matching packet before it reaches its destination while not closing the connection. That is the closest and correct IDP action for “silent discard” in the listed choices.

Option A, no action, is wrong because it does not discard anything; Juniper describes No Action as taking no enforcement action, typically used when the administrator only wants logging. Option B, close client and server, is wrong because that action actively closes the session by sending TCP RST packets to both sides, which is explicitly not silent. Option C, ignore connection, is wrong because it stops further IDP scanning for the rest of the connection; it does not discard the packet. Juniper distinguishes these actions clearly: drop packet discards the offending packet, drop connection blocks the whole connection, and close actions send reset packets. Reference topics: IDP actions, drop packet, close client and server, ignore connection, silent discard behavior.

The correct answers are A and C. In SSL forward proxy, the SRX sits between internal clients and external SSL/TLS servers. Juniper’s SSL proxy configuration documentation shows that a forward proxy profile is created when root-ca is configured and server-certificate is not configured. This root CA is used by the SRX to generate substitute certificates for intercepted SSL sessions, so internal clients must trust the CA used by the firewall. Juniper’s procedure specifically includes generating or loading a local certificate and applying it as the root-ca in the SSL proxy profile.

Option C is also correct because forward proxy terminates the client-side SSL session and establishes a separate SSL session toward the destination server. Juniper states that the SSL proxy acts as an SSL server to the client and establishes a new SSL session to the server; from the server’s perspective, the SRX is the SSL client. Option B is wrong because forward proxy intercepts the server certificate and creates a substitute certificate; forwarding the actual server certificate unchanged is associated with reverse proxy behavior. Option D is wrong because Encrypted Traffic Insights is not the required forward-proxy mechanism here. Reference topics: SSL Proxy, SSL forward proxy, root CA, client protection, certificate interception.

The correct answers are A, C, and E. Junos Space Security Director supports policy hierarchy and policy management at device, group, and global/all-devices levels. A device policy is created for a specific device and is used when a unique firewall policy must be pushed to one SRX Series Firewall. A group policy is shared across multiple devices and is used when the same policy configuration must be applied consistently to a set of managed firewalls. Juniper’s Security Director documentation explicitly describes device policy and group policy behavior, including the fact that device-specific policies are evaluated within the broader policy-ordering model.

The third correct policy type is global, often represented in Security Director workflows as all-devices/global policy behavior. Juniper Security Director product material describes granular control over global, group, and device-level firewall policies, which maps directly to the options in this question. Option B, local, is not the Security Director policy type being tested; local configuration may exist on an SRX, but it is not one of the Security Director policy hierarchy types listed here. Option D, universal, is also not a Junos Space Security Director policy type. Reference topics: Security Director, global policy, group policy, device policy, firewall policy hierarchy, centralized SRX policy management.

The correct answers are B and C. In an SRX chassis cluster, the fabric connection is represented by two logical fabric interfaces: fab0 and fab1. Juniper configuration examples show fab0 assigned to the node0-side fabric member interface and fab1 assigned to the node1-side fabric member interface; for example, Juniper shows fab0 using a node0 interface such as ge-0/0/1 and fab1 using a node1 interface such as ge-7/0/1. That eliminates option A, because fab0 and fab1 are not both independently located on both nodes; they represent the two node sides of the cluster fabric link.

Option C is also correct. Juniper states that only the same type of interfaces can be configured as fabric children, and for dual fabric links both child interface types should match, such as Gigabit Ethernet with Gigabit Ethernet or 10-Gigabit Ethernet with 10-Gigabit Ethernet. Option D is therefore wrong because mixed media types are not supported for the redundant fabric child interfaces.
