質問 # 12
Which two statements are correct when considering IPS rule base evaluation? (Choose two.)

A. IPS evaluates rules concurrently.
B. IPS applies the least severe action to traffic matching multiple rules.
C. IPS applies the most severe action to traffic matching multiple rules,
D. IPS evaluates rules sequentially

正解：A、C

解説：
The Intrusion Prevention System (IPS) is a feature that provides protection against network- based threats. The IPS uses a rule base to evaluate network traffic and apply actions based on the rules that match the traffic.
When evaluating the rule base, the IPS evaluates the rules concurrently (option A). This means that the IPS can apply multiple rules to the same traffic simultaneously. If multiple rules match the same traffic, the IPS applies the most severe action (option B). This means that if there are conflicting actions specified in different rules, the IPS will apply the action that has the highest severity. For example, if one rule specifies a "drop" action and another rule specifies a "log" action for the same traffic, the IPS will drop the traffic because dropping has a higher severity than logging.

質問 # 13
What are two examples of RTOs? (Choose two.)

A. session table entries
B. fabric link probes
C. control link heartbeats
D. IPsec SA entries

正解：B、C

質問 # 14
A routing change occurs on an SRX Series device that involves choosing a new egress interface.
In this scenario, which statement is true for all affected current sessions?

A. The current sessions do not change.
B. The current session are torn dowm only if the policy-rematch option has been enabled.
C. The current sessions might change based on the corresponding security policy.
D. The current sessions are torn down and go through first path processing based on the new route.

正解：D

質問 # 15
Which two solutions provide a sandboxing feature for finding zero-day malware threats? (Choose two.)

A. Sky ATP
B. IPS

質問 # 16
Which two statements are correct about security policy changes when using the policy rematch feature? (Choose two.)

A. When a policy change includes changing the policy's source or destination address match condition, all existing sessions are dropped.
B. When a policy change includes changing the policy's source or destination address match condition, all existing sessions are reevaluated.
C. When a policy change includes changing the policy's action from permit to deny, all existing sessions are dropped.
D. When a policy change includes changing the policy's action from permit to deny, all existing sessions are maintained

正解：B、C

解説：
policy rematch is a feature that enables the device to reevaluate an active session when its associated security policy is modified. The session remains open if it still matches the policy that allowed the session initially. The session is closed if its associated policy is renamed, deactivated, or deleted1.

質問 # 17
You enable chassis clustering on two devices and assign a cluster ID and a node ID to each device.
In this scenario, what is the correct order for rebooting the devices?

A. Reboot the primary device, then the secondary device.
B. Reboot only the primary device since the secondary will assign itself the correct cluster and node ID.
C. Reboot the secondary device, then the primary device.
D. Reboot only the secondary device since the primary will assign itself the correct cluster and node ID.

正解：A

解説：
when enabling chassis clustering on two devices, the correct order for rebooting them is to reboot the primary device first, followed by the secondary device. It is not possible for either device to assign itself the correct cluster and node ID, so both devices must be rebooted to ensure the proper configuration is applied.

The Security, Specialist (JNCIS-SEC) Study guide provides further information on how to download and install the IPS signature database. Enrolling the SRX Series device with Juniper ATP Cloud is not necessary to make a configuration work, and rebooting the SRX Series device is not required either.

質問 # 31
You want to set up JSA to collect network traffic flows from network devices on your network.
Which two statements are correct when performing this task? (Choose two.)

A. Statistical sampling decreases event correlation accuracy.
B. BGP FlowSpec is used to collect traffic flows from Junos OS devices.
C. Superflows reduce traffic licensing requirements.
D. Statistical sampling increases processor utilization

正解：A、B

解説：
The two correct statements when performing this task are A.
BGP FlowSpec is used to collect traffic flows from Junos OS devices, and C.
Statistical sampling decreases event correlation accuracy.
BGP FlowSpec is a Junos OS feature that allows network devices to send traffic flow information to a Juniper security device using BGP.
This allows the Juniper security device to monitor and collect the traffic flows and analyze them for suspicious activity.
Statistical sampling increases processor utilization by selecting only a subset of the data to be analyzed, which can help reduce the amount of data sent to the security device.
However, this also decreases the accuracy of event correlation, as some events may be missed due to the sampling. Superflows reduce traffic licensing requirements by offloading the processing of certain traffic flows to the device itself, instead of having it sent to the security device.
