- A
The possibility to schedule periodic transfers for ongoing sync
Storage Transfer Service supports recurring transfers for continuous synchronization.
- B
Data integrity verification using checksums
Checksums ensure data is not corrupted during transfer.
- C
Requirement to install an agent on the NAS
Why wrong: Storage Transfer Service does not require an agent; it can access HTTP sources or S3.
- D
Network bandwidth between on-premises and GCP
Bandwidth affects transfer speed and feasibility.
- E
The need for a physical appliance like Snowball Edge
Why wrong: Storage Transfer Service is online; physical appliances are for offline transfers.

CV0-004 Deployment Practice Question
This CV0-004 practice question tests your understanding of deployment. 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 company is migrating on-premises storage to Google Cloud Storage (GCS) using Storage Transfer Service. The source is an on-premises NAS with 100 TB of data. Which THREE considerations are relevant for this migration? (Select THREE.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The possibility to schedule periodic transfers for ongoing sync
Storage Transfer Service supports online transfers from sources like Amazon S3, HTTP/HTTPS, and on-premises via a staging area. Bandwidth, data integrity, and transfer time are key considerations.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

Common exam traps
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 practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

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 CV0-004 OSPF questions on adjacency and route selection.
