1

You need stateful firewall rules at the Amazon EC2 instance level. What should you configure?

AWS WAF
Network ACLs
Security Groups
Amazon VPC Route Tables
View Explanation
✓ Correct Answer: Security GroupsExplanation:Security Groups act as stateful firewalls for virtual instances, meaning they automatically permit return traffic.
2

What is an AWS Security Group?

A virtual firewall for your EC2 instances to control inbound and outbound traffic
A physical lock on a server rack
A team of security experts at AWS
A type of S3 bucket policy
View Explanation
✓ Correct Answer: A virtual firewall for your EC2 instances to control inbound and outbound trafficExplanation:Security groups act at the instance level, not the subnet level.
3

Are AWS Security Groups 'Stateful' or 'Stateless'?

Stateful (if you allow an inbound request, the response is automatically allowed)
Stateless (you must explicitly allow both inbound and outbound traffic)
Stateful only for HTTP
Neither
View Explanation
✓ Correct Answer: Stateful (if you allow an inbound request, the response is automatically allowed)Explanation:The 'state' of the connection is remembered, so return traffic is allowed regardless of outbound rules.
4

By default, what is the inbound traffic rule for a newly created Security Group?

All inbound traffic is denied
All inbound traffic is allowed
Only port 80 (HTTP) is allowed
Only traffic from other AWS accounts is allowed
View Explanation
✓ Correct Answer: All inbound traffic is deniedExplanation:Security groups provide 'default deny' for all incoming traffic.
5

By default, what is the outbound traffic rule for a newly created Security Group?

All outbound traffic is allowed
All outbound traffic is denied
Only SSH is allowed
Only traffic to the same AWS region is allowed
View Explanation
✓ Correct Answer: All outbound traffic is allowedExplanation:Security groups allow all outbound traffic by default until you change the rules.
6

How many Amazon EC2 instances can you associate with a single Security Group?

Multiple (thousands, as long as they are in the same VPC)
Only one
Exactly five
As many as the VPC CIDR allows
View Explanation
✓ Correct Answer: Multiple (thousands, as long as they are in the same VPC)Explanation:Security groups are scalable and can be applied to many instances simultaneously.
7

Can a Security Group rule reference another Security Group instead of an IP address range?

Yes, this allows for dynamic and secure communication between tiers
No, rules must always use IP ranges
Only for outbound rules
Only in the Default VPC
View Explanation
✓ Correct Answer: Yes, this allows for dynamic and secure communication between tiersExplanation:Referencing security groups (e.g., allowing traffic from the 'WebTier' SG to the 'DBTier' SG) is a best practice for security.
8

When you modify a rule in a Security Group, how long does it take for the change to take effect?

Immediately
After a 10-minute propagation delay
After the instances are restarted
Only after you 'Commit' the changes in the AWS Console
View Explanation
✓ Correct Answer: ImmediatelyExplanation:Security group rule modifications are applied instantly to all associated instances.
9

Which AWS tool can you use to automatically check if your Security Groups are allowing overly permissive access (e.g., 0.0.0.0/0 on port 22)?

AWS Trusted Advisor
Amazon CloudWatch
AWS CloudTrail
AWS IAM
View Explanation
✓ Correct Answer: AWS Trusted AdvisorExplanation:Trusted Advisor includes security checks that flag insecure resource configurations.
10

Can a single EC2 instance be associated with multiple Security Groups?

Yes, and the rules from all groups are aggregated
No, it is strictly limited to one
Only if using the 'Enhanced Networking' feature
Only if the instance is in a public subnet
View Explanation
✓ Correct Answer: Yes, and the rules from all groups are aggregatedExplanation:When multiple SGs are used, AWS evaluates all rules across all groups to determine if traffic is allowed.

22

Which statement correctly describes the nature of Security Groups in AWS?

They are stateful: if an inbound request is allowed, the response is automatically allowed
They are stateless: you must define rules for both directions
They act at the subnet level
They support 'Deny' rules
View Explanation
✓ Correct Answer: They are stateful: if an inbound request is allowed, the response is automatically allowedExplanation:Security groups are stateful, meaning they track the state of traffic and automatically allow returning traffic for an approved request.
23

How do Network ACLs differ from Security Groups in terms of rule evaluation?

NACLs evaluate rules in numerical order; Security Groups evaluate all rules and allow if there's a match
Security Groups are more restrictive than NACLs
NACLs only support 'Allow' rules
Security Groups apply to the subnet
View Explanation
✓ Correct Answer: NACLs evaluate rules in numerical order; Security Groups evaluate all rules and allow if there's a matchExplanation:Network ACLs process rules starting from the lowest number, while Security Groups aggregate all rules (implicit 'deny' for anything not matched).
24

An architect needs to block a specific IP address that is launching a DDoS attack on the web servers. Where should this block be implemented?

Network ACL (using a Deny rule)
Security Group
AWS IAM
Route Table
View Explanation
✓ Correct Answer: Network ACL (using a Deny rule)Explanation:Security Groups do not support 'Deny' rules. To block a specific IP, you must use a Network ACL.
25

A security group is associated with an EC2 instance. The group has an inbound rule allowing port 80 (HTTP) from 0.0.0.0/0. What happens to the outbound traffic from the instance on port 80?

It is automatically allowed because Security Groups are stateful
It is denied unless an outbound rule is added
It depends on the NACL setting
It is only allowed for 10 minutes
View Explanation
✓ Correct Answer: It is automatically allowed because Security Groups are statefulExplanation:Because they are stateful, responses to allowed inbound requests are automatically allowed to leave the instance.
26

In a sophisticated tiered architecture, how should a database security group be configured to be most secure?

Allow inbound traffic on the DB port with the Web Server Security Group as the source
Allow inbound traffic from the same subnet range
Allow traffic from 0.0.0.0/0 on the DB port
Disable the security group entirely
View Explanation
✓ Correct Answer: Allow inbound traffic on the DB port with the Web Server Security Group as the sourceExplanation:Nesting security groups (using one as the source for another) ensures only specific application components can talk to the database, regardless of their IP addresses.
27

A solutions architect is troubleshooting a connection issue to an EC2 instance. The security group has an inbound rule allowing SSH on port 22. What else must be checked regarding the security group to ensure the response can reach the client?

Nothing; security groups are stateful and automatically allow the response
An outbound rule for port 22
The ephemeral port range in the outbound rules
The NACL outbound rules
View Explanation
✓ Correct Answer: Nothing; security groups are stateful and automatically allow the responseExplanation:Because security groups are stateful, any allowed inbound traffic is automatically allowed to leave as a response.
28

To allow a fleet of web servers to communicate with a database cluster securely, which source should be used in the database security group's inbound rule?

The ID of the Security Group associated with the web servers
The public IP addresses of the web servers
The CIDR block of the web server subnet
The VPC CIDR block
View Explanation
✓ Correct Answer: The ID of the Security Group associated with the web serversExplanation:Using a security group ID as the source (referencing) is the best practice for dynamic and secure communication between tiers.
29

What is the maximum number of security groups that can be associated with a single network interface (ENI) by default?

5
1
10
Unlimited
View Explanation
✓ Correct Answer: 5Explanation:By default, you can associate up to 5 security groups with an ENI. This limit can be increased via a service quota request.
