Question
Which one of these is not a factor impacting sizing decisions?
Options
- ADecryption
- BSessions
- CRedundancy
- DNumber of applications
- EPerformance
- FNumber of rules
Explanation
The sheer number of applications identified by the firewall is not a primary factor influencing hardware sizing decisions, unlike decryption, session count, redundancy, performance, and rule count.
Common mistakes.
- A. Decryption significantly increases CPU and memory load, making it a critical factor for sizing decisions.
- B. The total number of concurrent sessions the firewall needs to maintain directly impacts memory and processing power requirements.
- C. Redundancy (e.g., High Availability configurations) impacts the number of physical devices needed, which is a fundamental sizing decision.
- E. Overall performance requirements, such as throughput and latency, are fundamental sizing considerations for any firewall.
- F. The number of security rules affects the processing overhead as the firewall must evaluate traffic against a larger and more complex policy set.
