- A
Use AWS Directory Service for Microsoft Active Directory with DNS
Provides DNS integrated with AD for hostname resolution.
- B
Configure DHCP option sets to use custom DNS
Why wrong: Does not provide AD integration.
- C
Install a DNS server on an Amazon Linux instance
Why wrong: Not integrated with Windows AD.
- D
Use Amazon Route 53 Resolver outbound endpoint
Why wrong: Resolves on-premises but not AD-integrated.
Question 756 of 1,733
Choosing DNS Strategy for SAP NetWeaver with Active Directory on AWS
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 is deploying SAP NetWeaver on AWS and needs to ensure that the SAP application servers can communicate with the SAP HANA database using the hostname. The environment uses a Windows Domain Controller for Active Directory. Which DNS resolution strategy should be used?
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
✓
Use AWS Directory Service for Microsoft Active Directory with DNS
Option A is correct because AWS Directory Service for Microsoft Active Directory provides a managed DNS service that integrates with Active Directory. This allows SAP application servers to resolve the SAP HANA database hostname via DNS, which is essential for SAP NetWeaver's hostname-based communication. The managed service ensures automatic DNS record updates and supports Windows-native DNS resolution without requiring custom infrastructure.
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 that candidates often assume any DNS solution (like Route 53 Resolver or a Linux DNS server) can handle Windows Active Directory hostname resolution, overlooking the need for native Windows DNS integration with dynamic updates and Kerberos authentication.
Detailed technical explanation
How to think about this question
AWS Directory Service for Microsoft Active Directory runs a managed Windows Server DNS server that supports secure dynamic updates and SRV record registration, which SAP NetWeaver relies on for service discovery. The DNS service automatically registers A records for domain-joined instances, ensuring that SAP application servers can resolve the HANA database hostname regardless of IP changes. In contrast, using a non-Windows DNS server would require manual DNS record management and would not support Active Directory-integrated authentication for DNS updates.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

Common DNS Record Types
| Record | Purpose | Example |
|---|---|---|
| A | IPv4 address mapping | example.com → 93.184.216.34 |
| AAAA | IPv6 address mapping | example.com → 2606:2800::1 |
| CNAME | Alias to another hostname | www → example.com |
| MX | Mail server for domain | example.com → mail.example.com (priority 10) |
| TXT | Text data (SPF, DKIM, verification) | v=spf1 include:_spf.example.com ~all |
| NS | Authoritative name servers | example.com NS ns1.example.com |
| PTR | Reverse DNS (IP → hostname) | 34.216.184.93.in-addr.arpa → example.com |
| SOA | Zone authority record | Primary NS, admin email, serial, TTL defaults |
