Answer: C

Explanation:

Step-by-Step

Understand the Problem:

An EC2 instance needs to be reachable from the internet.

Analyze the Requirements:

Ensure proper routing for internet connectivity.

Evaluate the Options:

Option A: A route for 0.0.0.0/0 that points to a NAT gateway.

NAT gateways allow instances in private subnets to access the internet, not the other way around.

Option B: A route for 0.0.0.0/0 that points to an egress-only internet gateway.

Egress-only gateways are for IPv6 traffic and do not provide inbound internet access.

Option C: A route for 0.0.0.0/0 that points to an internet gateway.

Internet gateways provide both inbound and outbound internet access. Option D: A route for 0.0.0.0/0 that points to an elastic network interface. Elastic network interfaces do not provide internet routing. Select the Best Solution:

Option C: Adding a route to the internet gateway ensures the EC2 instance is reachable from the internet.

Reference: Amazon VPC Internet Gateway

Configuring a route to the internet gateway ensures proper internet connectivity for the EC2 instance.
