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: D

Explanation: The incident was auto cleared because within five minutes, the packet loss percentage dropped to a level where the host IP of the original rule matches the host IP of the clear condition pattern. The clear condition pattern specifies that if there is an event with a packet loss percentage less than or equal to 10% and a host IP that matches any host IP in this incident, then clear this incident.

Correct Answer: A

Explanation: The UEBA agent status shows that it has been operationally down for one day and three hours ago (1d3h). This means that it has been down for 24 hours plus three hours, which is equal to 21 hours.

Correct Answer: B

Explanation: The profile database contains CPU utilization values from day one. At midnight on the second day, the CPU utilization values from the daily database will be merged with the profile database using a weighted average formula:

New value = (Old value x Old weight) + (New value x New weight) / (Old weight + New weight)

The weight is determined by the number of days in each database. In this case, the profile database has one day of data and the daily database has one day of data, so the weight is equal for both databases. Therefore, the formula simplifies

to:

New value = (Old value + New value) / 2

In the profile database, in the Hour of Day column where 9 is the value, the updated minimum, maximum, and average CPU utilization values are:

Min CPU Util = (32.31 + 32.31) / 2 = 32.31 Max CPU Util = (33.50 + 33.50) / 2 = 33.50 AVG CPU Util = (32.67 + 32.67) / 2 = 32.67

Correct Answer: BC

Explanation: Reconnaissance and Discovery are two Tactics in the MITRE ATTandCK framework. Tactics are the high-level objectives of an adversary, such as initial access, persistence, lateral movement, etc. Reconnaissance is the tactic of gathering information about a target before launching an attack. Discovery is the tactic of exploring a compromised system or network to find information or assets of interest. References: Fortinet NSE 7 - Advanced Analytics 6.3 escription, page 21

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: BDE

Explanation: You can empower SOC by deploying FortiSOAR in the following ways:

Collaborative knowledge sharing: FortiSOAR allows you to create and share playbooks, workflows, tasks, and notes among SOC analysts and teams. This enables faster and more consistent incident response and reduces duplication of

efforts.

Reduce human error: FortiSOAR automates repetitive and tedious tasks, such as data collection, enrichment, analysis, and remediation. This reduces the risk of human error and improves efficiency and accuracy. Address analyst skills gap:

FortiSOAR provides a graphical user interface for creating and executing playbooks and workflows without requiring coding skills. This lowers the barrier for entry-level analysts and helps them learn from best practices and expert knowledge.

Correct Answer: BCE

Explanation: The modes of Data Ingestion on FortiSOAR are notification based, app push, and schedule based. Notification based mode allows FortiSOAR to receive data from external sources via webhooks or email notifications. App push mode allows FortiSOAR to receive data from external sources via API calls or scripts. Schedule based mode allows FortiSOAR to pull data from external sources at regular intervals using connectors. References: Fortinet NSE 7 - Advanced Analytics 6.3 escription, page 17

Correct Answer: C

Explanation: FortiSIEM allows EPS bursting to handle event spikes without dropping events or violating the license agreement. EPS bursting means that FortiSIEM will let you burst up to five times the licensed EPS at any given time, provided it has accumulated enough unused EPS from previous time intervals.

Correct Answer: ABE

Explanation: phRuleMaster is a process that performs rule evaluation and incident generation on FortiSIEM. phRuleMaster queues up the data being received from the phRuleWorkers into buckets based on time intervals, such as one minute, five minutes, or ten minutes. phRuleMaster is present on both the supervisor and workers nodes of a FortiSIEM cluster. phRuleMaster wakes up every 30 seconds to evaluate all the rule data in parallel using multiple threads.
