GCDL Practice Question: When data is transmitted between a user's browser…
This GCDL practice question tests your understanding of when data is transmitted between a user's browser…. 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.
When data is transmitted between a user's browser and a Google Cloud-hosted web application over HTTPS, which security protection does this provide?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
It encrypts data stored in the server's database.
HTTPS only protects data in transit. Database encryption (at rest) is a separate mechanism handled by Google Cloud's automatic encryption of stored data.
B
Best answer
It encrypts data in transit between the user's browser and the server, preventing eavesdropping and tampering.
HTTPS/TLS encrypts the connection, ensuring data cannot be intercepted or modified as it travels between the user and the application. This is encryption in transit.
C
Distractor review
It prevents unauthorized users from accessing the Google Cloud Console.
HTTPS encrypts data in transit between browser and server. Console access is controlled by IAM authentication, not by HTTPS on the application.
D
Distractor review
It authenticates the user and verifies their permissions to use the application.
TLS/HTTPS establishes an encrypted channel and authenticates the SERVER (via certificate), but does not authenticate the user. User authentication requires credentials (password, SSO, etc.).
Common exam trap
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.
Technical deep dive
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.

Question 1
A traditional retailer currently maintains its own data centers, purchasing servers every 3–5 years and paying for facilities, power, and staff regardless of demand. When it migrates its workloads to the public cloud, which change in cost model does it experience?
Question 2
An e-commerce company plans its infrastructure for peak shopping events (e.g., Black Friday) which drive 50× normal traffic. On-premises, they must maintain 50× capacity year-round. In the cloud, they provision 50× capacity only during peak periods. Which cloud characteristic enables this cost optimization?

FAQ
Questions learners often ask
What does this GCDL question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: It encrypts data in transit between the user's browser and the server, preventing eavesdropping and tampering. — HTTPS uses TLS (Transport Layer Security) to encrypt data in transit between the browser and the server. This prevents eavesdropping (interception of unencrypted data), tampering (modification of data in transit), and impersonation (fake servers). Google Cloud terminates TLS at the load balancer or Cloud CDN edge, and can also encrypt traffic between GCP services over internal networks. Encryption in transit and at rest are both default in Google Cloud.
What should I do if I get this GCDL question wrong?
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 GCDL NAT questions on configuration and troubleshooting.
