The answer is to use cloud regions in each geographic area where data is stored and processed. This approach directly enforces data sovereignty by ensuring that data never leaves the legal jurisdiction where it was collected, which is critical for compliance with laws like the EU’s GDPR, the US’s CLOUD Act, and Asia’s varying data localization mandates. In a hybrid cloud model, this means mapping workloads to specific regional data centers rather than relying on a single global encryption key, which only protects data at rest or in transit but does not control its physical location. On the CompTIA SecurityX CAS-004 exam, this concept tests your understanding of how to balance operational flexibility with regulatory compliance—a common trap is confusing encryption or VPNs with location enforcement. Remember the mnemonic “Regions for Regulations” to recall that geographic placement, not technical controls alone, satisfies sovereignty requirements.
CAS-004 Governance, Risk and Compliance Practice Question
This CAS-004 practice question tests your understanding of governance, risk and compliance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 multinational corporation is migrating its data centers to a hybrid cloud model. The security team must ensure that data sovereignty laws are respected. The company operates in the EU, US, and Asia. Which of the following is the BEST approach?

Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use cloud regions in each geographic area where data is stored and processed.
B is correct. Using cloud regions ensures data is stored and processed within legal boundaries. Single global encryption key does not address location. VPN is for connectivity, not sovereignty. DPA is for processing agreements, not location enforcement.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Require all employees to sign a data processing agreement.
Why it's wrong here
DPAs govern data processing but do not control where data is stored.
✗
Encrypt all data at rest and in transit using a single global encryption key.
Why it's wrong here
Encryption does not ensure data remains in a specific geographic location.
✗
Implement a virtual private network between all data centers and cloud providers.
Why it's wrong here
VPN provides secure connectivity but does not enforce data sovereignty.
✓
Use cloud regions in each geographic area where data is stored and processed.
Why this is correct
Cloud regions allow data to stay within jurisdictional boundaries.
Clue confirmation
The clue word "best" in the question point toward this answer.
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
OSPF neighbours must agree on key parameters.
Router ID selection can affect neighbour relationships and LSDB output.
OSPF cost influences the preferred path.
A route can appear in OSPF information but not become the installed route.
TExam Day Tips
→Check area mismatch first when OSPF adjacency fails.
→Review passive interfaces when a network is advertised but no neighbour forms.
→Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
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 OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related CAS-004 OSPF questions on adjacency and route selection.
