CAS-004 Governance, Risk and Compliance Practice Question
This CAS-004 practice question tests your understanding of governance, risk and compliance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security manager is reviewing business continuity plans. Which element is MOST critical to test regularly?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Failover capability of critical systems
Option A is correct because failover capability ensures systems can be restored. Option B is wrong contact lists need updates but are not the most critical to test. Option C is wrong backup media must be tested but failover tests the whole process. Option D is wrong alternate site readiness is part of failover testing.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Updated contact lists
Why it's wrong here
Contact lists are important but not as critical as testing system recovery.
✓
Failover capability of critical systems
Why this is correct
Testing failover validates that critical systems can be recovered in a disaster.
Related concept
Static NAT maps one inside address to one outside address.
✗
Alternate site readiness
Why it's wrong here
Alternate site testing is part of failover testing, but failover covers the entire process.
✗
Backup media integrity
Why it's wrong here
Backup testing is important but failover testing is more comprehensive.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related CAS-004 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Failover capability of critical systems — Option A is correct because failover capability ensures systems can be restored. Option B is wrong contact lists need updates but are not the most critical to test. Option C is wrong backup media must be tested but failover tests the whole process. Option D is wrong alternate site readiness is part of failover testing.
