Question 1: Which Azure DNS record type is used to map a hostname to an IPv4 address?
- AAAA
- A (Correct answer)
- CNAME
- MX
Correct answer: A
An A record maps a hostname to a 32-bit IPv4 address in Azure DNS.
Question 2: You need to route traffic to the endpoint with the lowest latency for US-based users. Which Azure Traffic Manager routing method should you use?
- Weighted
- Priority
- Performance (Correct answer)
- Geographic
Correct answer: Performance
The Performance routing method directs users to the closest endpoint based on network latency measurements.
Question 3: What is the purpose of an alias record in Azure DNS?
- Maps a domain to an on-premises IP
- Points to an Azure resource and updates automatically when the resource IP changes (Correct answer)
- Creates a wildcard DNS entry
- Delegates a subdomain to a different DNS zone
Correct answer: Points to an Azure resource and updates automatically when the resource IP changes
Azure DNS alias records automatically track changes to an Azure resource's IP address, eliminating dangling DNS pointers.
Question 4: Which Traffic Manager profile type allows you to combine multiple routing methods in a hierarchy?
- Priority
- Nested (Correct answer)
- Weighted
- Multivalue
Correct answer: Nested
Nested Traffic Manager profiles let you embed one profile as an endpoint of another, combining routing methods.
Question 5: You want Azure DNS to resolve names for a private virtual network without exposing the zone to the internet. What should you create?
- A public DNS zone
- A private DNS zone linked to the VNet (Correct answer)
- A DNS forwarder VM
- An Azure Firewall DNS proxy
Correct answer: A private DNS zone linked to the VNet
Azure Private DNS zones are linked to one or more VNets and are not resolvable from the public internet.
Question 6: Which Traffic Manager routing method distributes traffic based on assigned percentage weights across endpoints?
- Geographic
- Weighted (Correct answer)
- Subnet
- Performance
Correct answer: Weighted
Weighted routing sends a proportional share of traffic to each endpoint according to its configured weight value.
