Which following statement is true in respect to the initial settings that will be applied to this security group if you choose to use the default settings for this group?

Any person or application that interacts with AWS requires security credentials. AWS uses these credentials to identify who is making the call and whether to allow the requested access. You have just set up a VPC network for a client and you are now thinking about the best way to secure this network. You set up a security group called vpcsecuritygroup.

Which following statement is true in respect to the initial settings that will be applied to this security group if you choose to use the default settings for this group?
A . Allow all inbound traffic and allow no outbound traffic.
B . Allow no inbound traffic and allow all outbound traffic.
C . Allow inbound traffic on port 80 only and allow all outbound traffic.
D . Allow all inbound traffic and allow all outbound traffic.

Answer: B

Explanation:

Amazon VPC provides advanced security features such as security groups and network access control lists to enable inbound and outbound filtering at the instance level and subnet level.

AWS assigns each security group a unique ID in the form sg-xxxxxxxx. The following are the initial settings for a security group that you create:

Allow no inbound traffic

Allow all outbound traffic
