Exam AZ-104 topic 5 question 141 discussion

Looks like section of question is missing, but I’d go with NYN.

NYN is a correct answer. Analysis of the Statements: Statement 1: From VM1, server1.contoso.com resolves to 131.107.3.3. VM1 in VNET1 uses the Azure-provided DNS, which does not reference the DNS records on VM4. Result: No. Statement 2: From VM2, server1.contoso.com resolves to 131.107.3.3. VM2 in VNET2 uses a custom DNS (192.168.0.5), which points to VM4's DNS server. VM4's DNS contains a record for server1.contoso.com resolving to 131.107.3.3. Result: Yes. Statement 3: From VM3, server2.contoso.com resolves to 131.107.2.4. VM3 in VNET3 uses a custom DNS (192.168.0.5), which points to VM4's DNS server. VM4's DNS contains a record for server2.contoso.com, but it resolves to 131.107.3.4, not 131.107.2.4. Result: No. Final Answer: Statement 1: No Statement 2: Yes Statement 3: No

The answer of 1 is yes DNS Resolution Process: (1)When VM1 (in vNet1) needs to resolve server1.contoso.com, it queries the Azure-provided DNS server. The Azure-provided DNS server does not directly forward queries to custom DNS servers in other virtual networks. (2)VM1 can send a DNS query directly to the custom DNS server on VM4 (192.168.0.5) because of the peering. VM4, being authoritative for the contoso.com zone, responds with the IP address 131.107.3.3 for server1.contoso.com

N Y N - peeering doesn't really change anything because the DNS resolution depends primarily on the DNS server configuration for each VNet.

Provided answer is correct (considering the missing image ) VM1/VNET1 uses Default AZ DNS and will resolve to what you have configured there - 131.107.3.3 ans = Yes VM2/VNET2 uses Custom DNS and will resolve to what you have configured there - 131.107.2.3 not 131.107.3.3 ans =No VM3/VNET3 uses Custom DNS and will resolve to what you have configured there - 131.107.2.4 ans =Yes

- From VM1, server1.contoso.com resolves to 131.107.3.3 = Yes (Azure Private DNS manages and resolves domain names in the virtual network without the need to configure a custom DNS solution. VNET are peered, it will look up to VM4 to resolve DNS) - From VM2, server1.contoso.com resolves to 131.107.3.3 = No ( VNET2 DNS 192* / VM2 IP 172*, different IP range) - From VM3, server2.contoso.com resolves to 131.107.2.4 = No (Wrong value 3.4 not 2.4 )

Answer is YNY Below is the missing paragraph f VNET1, VNET2, and VNET3 are peered. VM4 has a DNS server that is authoritative for a zone named contoso.com and contains the records shown in the following table. Name. Type. Value Server1. A. 131.107.2.3 Server2. A. 131.107.2.4

Passed AZ-104 today 03/07/24 879%. 99% of Examtopics questions in my test with exact same wording. This question was on the test, not sure anymore about my answer, but anyway. Very Thanks to Examtopics.

VM4 is authoritative for a zone named contoso.com, so you always come to this dns server. if you use custome or azure default. because azure default do a lookup to the same server in the end. that is why you don't have a table in the question for azure default.

Azure provided DNS doesn't resolve record in custom DNS even the VNETs are peered.

Answer should be YNY. A portion of the question is missing.

The first question should be YES too because VNET1 is using default DNS server and as all VNET are peered, it will look up to VM4 to resolve DNS.

NYN... There is no way 3 is Y because it has a 2.4 IP which doesn't exist in the question.

This is one of the several questions asking which one has higher priority - the (custom) DNS bound to a VNET or the private DNS zone linked to the same VNET. According to my test (and also the answer from chatGPT), the private DNS zone has priority. It is the only one which is used if the request is going to a domain hosted by the private DNS zone. If the request is going to a domain which is not in the provate DNS zone, then the default or custom DNS for the VNET is used. Based on this, the answers are Y-Y-Y Why - because both VM1 and VM2 are linked to the private DNS zone, where we have the record for server1.contoso.com -> 131.107.3.3 Also, asuming that the missing explanation of the second table says "VM4 is DNS server and it has the following records", and VM3 points to this DNS server, it will see and resolve the server2.contoso.com -> 131.107.2.4. Note that VNET3 (where VM3 is) is not linked to the private DNS zone. https://www.examtopics.com/discussions/microsoft/view/78995-exam-az-104-topic-5-question-93-discussion/ commentary: Trevor_VT

it's NNN VNET 1,2,3 are peered VM4 has Authority. VM3 and VM4 are in same VNET But last question has wrong IP address so NO

Wrong correct ANS is NYY even though VNET2 has a VM acting as an authoritative DNS server, VMs in VNET1 that are using Azure-Provided DNS servers will not directly use the authoritative DNS server in VNET2 for DNS resolution. Instead, they will rely on the Azure-Provided DNS servers assigned to VNET1 for resolving DNS queries. If you want VMs in VNET1 to use the authoritative DNS server in VNET2, you would need to configure custom DNS settings on those VMs to point to the IP address of the authoritative DNS server in VNET2. This would override the default Azure-Provided DNS settings and direct DNS queries to the specific DNS server you've configured.
