Prática AWS Certified Security - Specialty
During an active incident, a responder needs to isolate a compromised EC2 instance from the network immediately while preserving its memory and disk state for forensic analysis, without terminating it. Which combination of actions best achieves this?
Dois hábitos antes da primeira questão
- EVIDENCE-BACKEDAnswer from memory first, then check. It feels harder than rereading, and it works better. (Roediger and Karpicke, 2006 and others)
- EVIDENCE-BACKEDSet the confidence slider before you check. Your rating on each question shows where you feel sure and are wrong. (Couchman et al., 2016)
Por que funciona
EVIDENCE-BACKED Pelo menos um estudo revisado por pares ou uma fonte oficial encontrou o efeito ou afirma o fato. Um estudo pode ser pequeno.
Tested students kept more at two days and one week than students who restudied, and the result held in a randomized trial with medical residents at six months.
Per-question confidence predicted real exam performance far better than post-exam feelings.
