Answer – D
http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resource-record-sets-choosing-alias-non-alias.html
Yes – D is correct.
Hi Ratna,
how can be D? i think C is the correct
http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/using-domain-names-with-elb.html
B.
By using an A record
This question was also on the SAA exam.
I am wrong above. C is correct.
Next, use your DNS service, such as your domain registrar, to create a CNAME record to route queries to your load balancer. For more information, see the documentation for your DNS service.
http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/using-domain-names-with-elb.html
CNAME records must always point to another domain name, never directly to an IP address.
B is OK but we have more specific one from D so that D will be the best answer. CNAME only works for subdomains or naked domains but Alias records do both root and naked (without www, or subdomains) domains.
Amazon Route 53 offers a special type of record called an ‘Alias’ record that lets you map your zone apex (example.com) DNS name to your ELB DNS name (i.e. elb1234.elb.amazonaws.com).
D is Answer.
Amazon Route 53 doesn’t charge for DNS queries for alias record sets, and you can use alias record sets to route DNS queries to your load balancer for the zone apex of your domain (for example, example.com).
The answer is D
D is the right answer
D should be the answer.
You cannot create a CNAME record at the top node of a DNS namespace, also known as the zone apex. For example, if you register the DNS name example.com, the zone apex is example.com.
You can create an alias resource record set at the zone apex.
http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resource-record-sets-choosing-alias-non-alias.html
Answer is D. http://docs.aws.amazon.com/govcloud-us/latest/UserGuide/setting-up-route53-zoneapex-elb.html
Alias resource record sets are virtual records that work like CNAME records. But they differ from CNAME records in that they are not visible to resolvers. Resolvers only see the A record and the resulting IP address of the target record. As such, unlike CNAME records, alias resource record sets are available to configure a zone apex (also known as a root domain or naked domain) in a dynamic environment.
The answer is….
D
you can use Amazon Route 53 as your DNS service. You create a hosted zone, which contains information about how to route traffic on the Internet for your domain, and an alias resource record set, which routes queries for your domain name to your load balancer. Amazon Route 53 doesn’t charge for DNS queries for alias record sets, and you can use alias record sets to route DNS queries to your load balancer for the zone apex of your domain
