Demo Questions

Question 1
When it comes to licensing, what is the difference between Events and Flows and how they are licensed?
  1. Flows are licensed based on overall count over a minute, where Events are licensed based on overall count per second.
  2. Flows are licensed based on overall count per second, where Events are licensed based on overall count over a minute.
  3. Flows and Events are both licensed by overall count per minute under an Upgraded License and per second on a Basic License.
  4. Flows and Events are both licensed by overall count per second under an Upgraded License and per second on a Basic License.
Correct answer: A
Explanation:
A significant difference between event and flow data is that an event, which typically is a log of a specific action such as a user login, or a VPN connection, occurs at a specific time and the event is logged at that time. A flow is a record of network activity that can last for seconds, minutes, hours, or days, depending on the activity within the session. For example, a web request might download multiple files such as images, ads, video, and last for 5 to 10 seconds, or a user who watches a Netflix movie might be in a network session that lasts up to a few hours. The flow is a record of network activity between two hosts. Reference: https://www.ibm.com/support/knowledgecenter/en/SS42VS_7.2.8/com.ibm.qradar.doc/c_qradar_deploy_event_and_flow_pipeline.html

Question 2
When an IBM Security QRadar SIEM V7.2.8 distributed deployment requires scaling horizontally to achieve Event per Second (EPS) requirements, what QRadar 
Component needs to be added to meet the EPS demands? 
  1. Event Manager
  2. Event Indexing
  3. Event Collector
  4. Event Processor
Correct answer: D
Explanation:
The QRadar SIEM Event Processor Virtual 1699 appliance supports the following items:Up to 10,000 events per second 2 TB or larger dedicated event storage Reference: https://www.ibm.com/support/knowledgecenter/SS42VS_7.2.4/com.ibm.qradar.doc_7.2.4/c_siem_vrt_ap_ov.html

Question 3
The event data collected by IBM Security QRadar SIEM V7.2.8 is being deleted after one month. The legal department required the data be kept for two months. 
What can the administrator do to accommodate this requirement?
  1. Change the nightly backup Priority to “High”.
  2. Change the nightly backup to a monthly backup.
  3. Change the Default Event Retention Policy property field “Do not delete data in this bucket” to two months.
  4. Change the Default Event Retention Policy property field “Keep data placed in this bucket for” to two months.
Correct answer: D
Explanation:
When storage space is required - Select this option if you want events or flows that match the Keep data placed in this bucket for parameter to remain in storage until the disk monitoring system detects that storage is required. If used disk space reaches 85% for records and 83% for payloads, data will be deleted. Deletion continues until the used disk space reaches 82% for records and 81% for payloads. When storage is required, only events or flows that match the Keep data placed in this bucket for parameter are deleted. Reference: https://www.ibm.com/developerworks/community/forums/atom/download/Event_Flow_Retention_QRadar_72_AdminGuide.pdf?nodeId=593f2b31-a858-4210-b380-4674894a6ad9

Question 5
The Administrator of an IBM Security QRadar SIEM V7.2.8 deployment needs to determine which rules are most active in generating offenses. 
How would the Administrator accomplish this from the Offenses tab of the QRadar console?
  1. Rules -> Group -> “Most Active Offenses”.
  2. Rules -> Rules -> Offense Count to reorder the column in descending order.
  3. All Offenses -> All Offenses -> Offense Count to reorder the column in descending order.

Correct answer: B
Explanation:
1. Click the Offenses tab. 2. On the navigation menu, click Rules. To determine which rules are most active in generating offenses, from the rules page, click Offense Count to reorder the column in descending order. 3. Double-click any rule to display the Rule Wizard. You can configure a response to each rule. Reference: ftp://ftp.software.ibm.com/software/security/products/qradar/documents/7.2.8/en/b_qradar_tuning_guide.pdf

Question 7
An Administrator working with IBM Security QRadar SIEM V7.2.8 needs to copy data and configuration backup files from the previous day to an off-site location. 
What is the default location where these files can be found?
  1. /store/backup
  2. /store/exports
  3. /store/postgres
  4. /store/backupHost
Correct answer: A
Explanation:
The default location is /store/backup. This path must exist before the backup process is initiated. If this path does not exist, the backup process aborts. If you modify this path, make sure the new path is valid on every system in your deployment. Reference: ftp://ftp.software.ibm.com/software/security/products/qradar/documents/7.2.8/en/b_qradar_admin_guide.pdf
