NEW QUESTION # 23
In Juniper high availability (HA) SRX Series device implementations, which interface will be used to exchange session state, configuration files, and ensure session continuity across nodes using the proprietary Trivial Network Protocol?
Answer: C
Explanation:
The correct answer is A. fab. In SRX Series chassis clustering, the fabric interface, shown as fab0/fab1, is the data-plane HA link used between cluster nodes. Juniper states that SRX chassis clusters use the fabric interface for session synchronization and traffic forwarding, and that the fabric link synchronizes dynamic runtime state, including session-state objects created by NAT, ALG, authentication, and IPsec processing.
This is what enables stateful failover and session continuity when traffic processing moves between nodes.
Option B, fxp0, is wrong because fxp0 is the out-of-band management interface, not the chassis-cluster synchronization path. Option C, fxp1, is tempting but wrong for this question: fxp1 is the control-link interface used for control-plane cluster functions such as heartbeats and cluster control communication, not the main session-state synchronization path. Option D, swfab, is not the standard SRX chassis-cluster fabric interface name used for this function. Juniper's clustering configuration examples specifically define fab0 and fab1 as the interfaces used for the fabric connection and data-plane RTO/session synchronization.
NEW QUESTION # 24
Which two statements are correct about a chassis cluster? (Choose two.)
Answer: A,C
Explanation:
The correct answers are A and B. In an SRX chassis cluster, the cluster ID identifies the chassis cluster, and valid operational cluster IDs are nonzero values. Juniper's chassis cluster command documentation states that the system uses the chassis cluster ID and node ID to apply the correct node-specific configuration, and the command writes the chassis cluster ID and node ID to EPROM. When the cluster ID is set to 0, clustering is disabled; therefore, the HA cluster configuration is effectively ignored because the device is no longer operating as a chassis-cluster member.
Option B is also correct because Juniper states that chassis cluster ID and node ID changes take effect only after the system is rebooted. That is why the operational command format includes the reboot behavior when setting cluster-id and node. Option C is wrong because node ID 0 is valid; it identifies node0 in the two-node cluster. Option D is wrong because SRX chassis clusters use node IDs 0 and 1 only; the 1-255 range applies to cluster IDs, not node IDs. Reference topics: HA Clustering, cluster ID, node ID, EPROM, chassis cluster enablement, node-specific configuration.
NEW QUESTION # 25
Your manager asks you to update your SRX Series device's IDP security package. You perform the required steps; however, when you attempt to install the package, you receive an error.
Referring to the exhibit, which two statements are correct about this error? (Choose two.)
Answer: B,D
Explanation:
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.
NEW QUESTION # 26
How does the SSL proxy service identify SSL traffic?
Answer: C
Explanation:
The correct answer is B. by using AppID results. Junos SSL proxy does not identify SSL/TLS sessions by assuming that encrypted traffic always uses TCP/443. That would be technically weak because SSL/TLS can run on nonstandard ports, and non-SSL applications can also use common HTTPS ports. Juniper's SSL proxy documentation explains that SSL proxy works with application security services and that AppID is used in the encrypted-traffic inspection workflow. In earlier wording from Juniper AppSecure material, SSL proxy uses application identification services to determine whether a session is SSL encrypted; in current Junos documentation, SSL proxy and AppID are tightly linked so encrypted sessions can be identified, decrypted, inspected, and then re-encrypted for enforcement.
Option A is wrong because the URL is inside the HTTP payload, and in HTTPS much of the meaningful HTTP content is encrypted before SSL proxy inspection occurs. Option C is wrong because destination port is only a rough hint, not a reliable detection method. Option D is wrong because certificates are used in the SSL
/TLS handshake and proxy trust model, but the service's traffic classification relies on AppID results, not merely reading the server certificate. Reference topics: SSL Proxy, AppID, encrypted session detection, SSL
/TLS inspection, application security services.
NEW QUESTION # 27
You are asked to ensure that traffic that matches an IDP policy is not impacted until administrators have a chance to evaluate it.
In this scenario, which IP action should be configured for the policy?
Answer: B
Explanation:
The correct answer is B. ip-notify. When administrators want visibility without enforcement impact, ip-notify is the correct IP action. Juniper Security Director documentation defines IP Notify as an IP action that does not take any action against future traffic but logs the event. That is exactly the requirement in the question:
traffic matching the IDP condition must not be blocked, closed, or rate-limited until administrators have reviewed the events and decided whether enforcement is appropriate.
Option A, ip-block, is wrong because it blocks future packets matching the IP action rule. That would immediately impact traffic. Option C, ip-connection-rate-limit, is wrong because it limits the connection rate and therefore changes traffic behavior before administrators complete evaluation. Option D, ip-close, is also wrong because it closes matching future sessions by sending reset packets to the client and server, which is disruptive. In a safe evaluation or tuning phase, the proper approach is to log and observe first, then move to stronger actions such as block, close, or rate-limit only after the detected condition has been validated.
Reference topics: IDP IP actions, ip-notify, event logging, non-disruptive evaluation mode, IDP policy tuning.
