Question 457 of 507

Google Cloud products, services, and solutions →easyMultiple ChoiceObjective-mapped

Quick Answer

The answer is Cloud DNS, the Google Cloud service that manages DNS records to route a custom domain like app.company.com to a load balancer. This is correct because Cloud DNS translates human-readable domain names into IP addresses by letting you create A, CNAME, or ALIAS records that point your custom domain directly to the load balancer’s frontend IP or hostname, enabling seamless traffic routing for internal applications. On the Google Cloud Digital Leader exam, this tests your understanding of how foundational networking services like DNS and load balancing work together to provide reliable, scalable access—a common scenario where candidates mistakenly choose Cloud Load Balancing alone, forgetting that DNS resolution is a separate layer. A helpful memory tip is to think of Cloud DNS as the “phonebook” that maps your custom domain to the load balancer’s address, while the load balancer itself handles the traffic distribution.

Cloud Digital Leader Practice Question: Google Cloud products, services, and solutions

This GCDL practice question tests your understanding of google cloud products, services, and solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 wants its internal applications to be accessible via a custom domain name (e.g., `app.company.com`) that routes to their Google Cloud load balancer. Which Google Cloud service manages DNS records for this?

A
Cloud CDN — it manages domain names for cached content.
Why wrong: Cloud CDN caches content at edge locations. DNS record management for custom domains is handled by Cloud DNS, not CDN.
B
Cloud DNS
Cloud DNS manages DNS zones and records. An A record pointing app.company.com to the load balancer's IP address routes users from the custom domain to the GCP load balancer.
C
Cloud Load Balancing — it automatically assigns domain names.
Why wrong: Cloud Load Balancing provides IP addresses for load balancers, not domain name management. DNS records in Cloud DNS map custom domain names to those IP addresses.
D
Cloud Armor — it routes traffic based on domain names.
Why wrong: Cloud Armor is a security service (WAF/DDoS). DNS routing requires Cloud DNS configuration.

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

✓

Cloud DNS

Cloud DNS is the correct service because it is Google Cloud's managed DNS service that translates human-readable domain names (like app.company.com) into IP addresses. It allows you to create and manage DNS records (such as A, CNAME, or ALIAS records) that point your custom domain to the IP address or hostname of your Google Cloud load balancer, enabling traffic routing to your internal applications.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is confusing services that handle traffic (like Cloud Load Balancing or Cloud Armor) with the service that manages DNS records, leading candidates to pick a service that operates at a different layer of the network stack.

Detailed technical explanation

How to think about this question

Cloud DNS uses Google's global anycast network to provide low-latency, highly available DNS resolution. It supports standard DNS record types (A, AAAA, CNAME, TXT, etc.) and integrates with Cloud Load Balancing via ALIAS records, which allow you to point a domain directly to a load balancer's IP address without needing to know the IP itself. In a real-world scenario, you would create a managed zone in Cloud DNS, add an A record or ALIAS record pointing to the load balancer's IP, and then update your domain registrar's nameservers to delegate authority to Cloud DNS.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.

TExam Day Tips

Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
