CorrectA, C
Explanation
Selecting the two correct combinations of a network or delivery service and its role.
- 1「AWS network or delivery service and its role」Correctly map the roles of CloudFront / Route 53 / Direct Connect / ELB
BIncorrect
Amazon Route 53 - a load balancer that distributes incoming traffic across multiple EC2 instances.
Distributing traffic across multiple instances is Elastic Load Balancing.
Route 53 is a DNS service, so the description is wrong and this is incorrect.
CCorrect
AWS Direct Connect - connects on-premises and AWS over a dedicated line.
Correct. AWS Direct Connect connects on-premises and AWS over a dedicated line that does not traverse the internet, providing stable bandwidth and low latency.
DIncorrect
Elastic Load Balancing - a DNS that resolves domain names into IP addresses.
The DNS that resolves domain names into IP addresses is Amazon Route 53.
ELB is a load balancer, so the description is wrong and this is incorrect.
EIncorrect
AWS Direct Connect - builds an encrypted tunnel over the internet within a few minutes.
Quickly building an encrypted tunnel over the internet is the description of AWS Site-to-Site VPN.
AWS Direct Connect is a dedicated line connection that does not traverse the internet and requires physical arrangements to provision. The characteristics are swapped, so it is incorrect.
Key Takeaway
Mapping: CloudFront = CDN (delivery) / Route 53 = DNS / ELB = load balancing / Direct Connect = dedicated line / Site-to-Site VPN = encrypted connection. Swapping roles is a classic trap.
