Keyword closest. Amazon Route 53 Geoproximity Routing: This routing policy directs traffic based on the geographic location of your users and your resources, ensuring that users are routed to the closest EC2 instances.

Correct answer is A Geo location is based on users location GeoProximity is based on the AWS services used by users.

A - "geolocation" is simple and effective, but it might not always direct users to the physically closest Region. It’s more about their geographic "label" (country/region). B - "geoproximity" is better for ensuring actual closeness but adds a bit more complexity. Then, I don't think ALB or NLB should be an argument here. NLBs are generally preferred for applications that require high throughput and low latency, especially if they are not using HTTP/HTTPS. NLBs operate at Layer 4 (TCP/UDP), so suitable for a wider range of applications than ALBs (Layer 7, HTTP/HTTPS). Even if the application does use HTTP/HTTPS, NLBs can still be used if you don't need the advanced features of an ALB (like content-based routing or host-based routing). Then again, the question haven't explicitly stated the protocol so oh well, I'm gonna go with B.

You can argue geolocation vs geoproximity all day but why would one use a NLB for an internet based app? The is the perfect use case for an ALB. A is the correct answer.

Which AWS Route 53 routing policy should be used to route traffic based on users' location? Geoproximity routing Geoproximity routing lets Amazon Route 53 route traffic to your resources based on the geographic location of your users and your resources.

Go with A

Correct answer is B!

The answer is A. routing traffic to the user region. Also, it can't be B. It says using a Network Load Balancer. you can't use a network load balancer for internet traffic

Correct answer is A

It is B: Geolocation: Primarily focuses on the user's location, allowing you to serve different content based on their geographic region. Geoproximity: Considers both the user's location and the location of your resources, dynamically choosing the closest option based on network latency.

Geolocation Routing Policy - Routes traffic based on the geographic location of the users. Geoproximity Routing Policy - Routes traffic based on the geographic proximity of the user to AWS resources.

Answer is B
