A client has reached the maximum of 5000 EPS for their 3128 All-in-One appliance. They have just completed an acquisition of a competitor company and would like to get them on-board with collecting events for correlation in QRadar. It has been determined that the newly acquired company has a large number of log sources, and it is estimated that its total EPS will be approx. 22000 EPS.
What will meet the hardware requirements when changing to a distributed environment?
Correct Answer:
D
🗳️
QRadar Event Processor 1628, with a Basic Licence, can process 2500 events per second (EPS), and with Upgraded license it can process 40,000 events per second.
Incorrect Answers:
A: QRadar Event Processor 1605 has a maximum capacity of events per second.
C: QRadar Event Processor 1624, with a Basic License, can process 2500 events per second (EPS), and with Upgraded license it can process only 20,000 events per second.

A Deployment Professional is asked to schedule the forwarding of events when the network is quiet, usually around 2 to 3 a.m. console time. The customer states that there is no restriction to bandwidth on the available 1 Gbp/s WAM connection during this time.
Which value should be used for the forward transfer rate?
Correct Answer:
A
🗳️
For the forward transfer rate, a value of 0 means that the transfer rate is unlimited.

A Deployment Professional working with IBM Security QRadar SIEM V7.2.7 is noticing system notifications relating to performance degradation of the CRE relating to expensive rules. Upon locating the rules that are being expensive they need to be modified to no longer trigger this notification.
What are three causes for a rule to become expensive? (Choose three.)
Correct Answer:
BCF
🗳️
A user can create a custom rule that has a large scope, uses a regex pattern that is not efficient, includes Payload contains tests, or combines the rule with regular expressions. When this custom rule is used, it negatively impacts performance, which can cause events to be incorrectly routed directly to storage. Events are indexed and normalized but they don't trigger alerts or offenses.

A Deployment Professional is working with IBM Security QRadar SIEM V7.2.7. for a new customer that is trying to create their network hierarchy. The customer currently has more than the maximum of 1,000 network objects and CIDR ranges. A few of the CIDRs of the customer are:
✑ 209.60.128.0/24
✑ 209.60.129.0/24
209.60.130.0/24
✑ 209.60.131.0/24
Which supernet should be used to shrink the amount of network objects for the supplied group of CIDRs?
Correct Answer:
C
🗳️
Supernetting, also called Classless Inter-Domain Routing (CIDR), is a way to aggregate multiple Internet addresses of the same class.
Using supernetting, the network address 209.60.128.0/24 and an adjacent address 209.60.129.0/24 can be merged into 209.60.128.0/23. The "23" at the end of the address says that the first 23 bits are the network part of the address, leaving the remaining nine bits for specific host addresses.
