NSE7_ADA-6.3 Online Practice Questions and Answers

Correct Answer: BC

Explanation: The device limit is a feature of the enterprise edition of FortiSIEM that restricts the number of devices that can be added to the system based on the license type. The device limit does not apply to the service provider edition, which allows unlimited devices per customer. The device limit is determined by the license type that was purchased from Fortinet, such as 100 devices, 500 devices, or unlimited devices.

Correct Answer: BCE

Explanation: The statements about collector communication with the FortiSIEM cluster that are true are:

Collectors communicate periodically with the supervisor node. Collectors send heartbeat messages to the supervisor every 30 seconds to report their status and configuration.

The supervisor periodically checks the health of the collector. The supervisor monitors the heartbeat messages from collectors and alerts if there is any issue with their connectivity or performance.

Collectors upload event data to any node in the worker upload list, but report their health directly to the supervisor node. Collectors use a round-robin algorithm to distribute event data among worker nodes in the worker upload list, which is

provided by the supervisor during registration. However, collectors only report their health and status to the supervisor node.

Correct Answer: C

Explanation: The collector processes are dependent on the registration with the supervisor. The phMonitor process is responsible for registering the collector to the supervisor and monitoring the health of other processes. After the registration is successful, the phMonitor will start the other processes on the collector.

Correct Answer: C

Explanation: Collectors cannot be defined before the worker upload address is set on the supervisor because collectors receive the worker upload address during the registration process. The worker upload address is a list of IP addresses of worker nodes that can receive event data from collectors. The supervisor provides this list to collectors when they register with it, so that collectors can upload event data to any node in the list.

Correct Answer: B

Explanation: If the Z-score for this rule is greater than or equal to three, it means that the rate of firewall connection is above the historical average value. The Z-score is a measure of how many standard deviations a value is away from the mean of a distribution. A Z-score of three or more indicates that the value is significantly higher than the mean, which implies an anomaly or deviation from normal behavior.

Correct Answer: B

Explanation: The syntax that will register a collector to the supervisor is phProvisionCollector --add . This command will initiate the registration process between the collector and the supervisor, and exchange certificates and configuration information. The parameter is the IP address of the supervisor node.

Correct Answer: B

Explanation: The rule is tracking the WMI response times from Windows devices using a baseline calculation. The rule will trigger an incident if the current WMI response time is greater than or equal to 1.50 times the average WMI response time in the last 30 minutes.

Correct Answer: C

Explanation: The incident from FortiSIEM shown in the exhibit is a brute force attack on a FortiGate device. The remediation option available to the administrator is to run the block IP FortiOS 5.4 action, which will block the source IP address of the attacker on the FortiGate device using a firewall policy.

Correct Answer: B

Explanation: Tactic is what an attacker hopes to achieve in the MITRE ATTandCK framework. Tactic is a high-level category of adversary behavior that describes their objective or goal. For example, some tactics are Initial Access, Persistence, Lateral Movement, Exfiltration, etc. Each tactic consists of one or more techniques that describe how an attacker can accomplish that tactic.

Correct Answer: C

Explanation: The user who would meet that condition is Tom. Tom has four rows in the results where the COUNT is greater than or equal to three, meaning he had at least three SSL VPN logon failures from the same source IP and reporting IP. The other users have either less than three rows or less than three COUNT in each row.
