NEW QUESTION # 19
You work on the security operations team that manages firewalls only. In your data center, there are two SRX chassis clusters. These clusters operate on VLAN 1042. The network team advises you that they see the same MAC address coming from both chassis clusters for reth0.
Why is this occurring?
Answer: B
Explanation:
The correct answer is A. The same cluster ID was used on both clusters. In an SRX chassis cluster, a redundant Ethernet interface, or reth, uses a cluster-derived virtual MAC address. When two separate chassis clusters are placed in the same Layer 2 domain and use the same cluster ID, their corresponding reth interfaces can generate the same virtual MAC address. That is exactly why the network team sees the same MAC address for reth0 from both clusters on VLAN 1042. Juniper community guidance states bluntly that the reth interface MAC address is derived from the cluster ID and that two clusters using the same ID produce identical MAC addresses.
Option B is wrong because split-brain would describe both nodes inside the same cluster thinking they are primary, not two separate chassis clusters producing the same reth MAC address. Option C is wrong because multiple SRX clusters can exist on the same VLAN if their cluster IDs are unique. Option D is wrong because LACP synchronization affects bundled link operation, not the generation of the reth virtual MAC address. The correction is to assign unique cluster IDs to clusters sharing the same Layer 2 segment. Reference topics: HA Clustering, chassis cluster ID, reth virtual MAC address, duplicate MAC prevention, Layer 2 cluster design.
NEW QUESTION # 20
Exhibit
Which two statements are correct about the configuration shown in the exhibit? (Choose two.)
Answer: B,D
Explanation:
The log session-init; command within the policy configuration specifies that an event log entry will be created every time a session is initialized, meaning each new session will generate a log event. This is useful for tracking and analyzing the traffic flows entering the device.
Changing session-init to session-close in the log statement would mean that the device logs sessions when they close instead of when they open. This setting is typically used to log details about the session upon termination, which can help in analyzing the duration, end status, and other parameters of sessions, including those of unidentified flows.
NEW QUESTION # 21
You administer a JSA host and want to include a rule that sets a threshold for excessive firewall denies and sends an SNMP trap after receiving related syslog messages from an SRX Series firewall.
Which JSA rule type satisfies this requirement?
Answer: D
Explanation:
An offense rule in JSA is designed to aggregate multiple events or log entries based on specified criteria into a single offense, which can then trigger responses such as notifications or actions like sending an SNMP trap. This type of rule is well-suited for scenarios where you need to monitor for patterns or rates of events, such as excessive firewall denies, and take action when these exceed defined thresholds.
Offense rules can analyze both event and flow data, making them highly versatile for comprehensive security monitoring.
NEW QUESTION # 22
Which action will the SRX Series device take if traffic matches the custom attack object shown in the exhibit?
Answer: A
Explanation:
The correct answer is A. the action taken is defined in the IDP policy that includes this attack object. The exhibit defines a custom attack object named BGP-DEFEND under the security idp custom-attack hierarchy.
The custom object includes metadata such as recommended-action drop, severity critical, and signature match conditions such as BGP update AS-path context and pattern 65501. However, an attack object by itself does not determine the final enforcement behavior. The attack object defines what to match; the IDP policy rule that references the object defines what action to take when that match occurs. Juniper describes attack objects as objects used inside IDP rules to identify malicious activity, while IDP rules include rule actions such as drop-packet, drop-connection, close-client, close-server, recommended, and others.
Option B is wrong because the firewall security policy enables IDP inspection by applying an IDP policy, but the IDP action is not selected directly by the normal security policy. Options C and D are too absolute. Even though the custom object shows recommended-action drop, that is only used if the IDP rule action invokes recommended behavior. Without seeing the IDP policy rule action, you cannot conclude reject or drop.
Reference topics: IDP custom attack objects, IDP policy rule actions, recommended action, signature-based attack matching.
NEW QUESTION # 23
What are two causes that end the processing of rules in IDP? (Choose two.)
Answer: C,D
Explanation:
The correct answers are B and D. A terminal rule is specifically designed to stop further rule evaluation.
Juniper states that the IDP rule-matching algorithm normally checks traffic against all matching rules in the rulebase, but when a terminal rule matches the source, destination, zones, and application, IDP does not continue to check subsequent rules for that same traffic. Juniper also warns that traffic matching a terminal rule is not compared to later rules even if it does not match the attack object inside that terminal rule.
Option D is also correct because the Ignore Connection action stops scanning traffic for the rest of the connection if an attack match is found. Juniper defines Ignore Connection as disabling the rulebase for that specific connection after a match. Option A is wrong because a close action closes the connection by sending reset behavior, but it is not the rule-processing control mechanism being tested. Option C is a trap: the exempt rulebase is used to suppress known false positives after an IPS rule match, but the two direct mechanisms that end IDP rule processing are terminal rule matching and ignore connection. Reference topics: IDP rulebases, terminal rules, Ignore Connection action, rule-matching algorithm, false-positive exemption.
