VPC DESIGN & NETWORK ARCHITECTURE (Q1–Q7)
,Q1. A company runs a multi-tier application in a VPC with private and public subnets.
The application requires secure outbound internet access from private EC2 instances
without allowing inbound internet traffic. Which architecture best meets this
requirement?
A. Attach an Internet Gateway to private subnets
B. Deploy a NAT Gateway in a public subnet
C. Use a VPN connection to the internet
D. Assign Elastic IPs to private instances
Correct Answer: 🔴 B. Deploy a NAT Gateway in a public subnet
Explanation: A NAT Gateway allows instances in private subnets to
initiate outbound traffic to the internet while preventing inbound
connections. Internet Gateways expose instances directly, violating
security requirements. VPN is not required for internet access, and
Elastic IPs would make instances publicly reachable, which is
undesired.
Q2. A solutions architect needs to design a VPC that isolates workloads while
allowing controlled communication between subnets. Which mechanism provides
the most granular traffic filtering at subnet level?
A. Security Groups
B. Network ACLs
C. Route Tables
D. Internet Gateways
Correct Answer: 🔴 B. Network ACLs
Explanation: Network ACLs operate at the subnet level and provide
stateless filtering, making them ideal for controlling traffic
between subnets. Security groups are instance-level and stateful.
Route tables control routing, not filtering.
Q3. An application requires low-latency private connectivity between two VPCs in
different AWS accounts within the same region. What is the most efficient solution?
,A. VPC Peering
B. Transit Gateway
C. Site-to-Site VPN
D. NAT Gateway
Correct Answer: 🔴 B. Transit Gateway
Explanation: Transit Gateway enables scalable, centralized inter-
VPC connectivity across accounts. VPC peering works but becomes
complex at scale. VPN is for hybrid connectivity, not VPC-to-VPC
optimization.
Q4. Which component enables DNS resolution for private hosted zones within a
VPC?
A. Route 53 Resolver
B. Internet Gateway
C. Elastic Load Balancer
D. CloudFront
Correct Answer: 🔴 A. Route 53 Resolver
Explanation: Route 53 Resolver handles DNS queries inside VPCs
and supports private hosted zones. Other options do not provide
internal DNS resolution functionality.
Q5. A company wants to ensure traffic between two subnets does not traverse the
internet. Which AWS feature ensures internal routing only?
A. NAT Gateway
B. Route Tables with local target
C. Internet Gateway
D. Elastic IP
Correct Answer: 🔴 B. Route Tables with local target
Explanation: The “local” route ensures intra-VPC communication
without external routing. NAT and Internet Gateways introduce
external routing paths.
, Q6. Which feature allows secure hybrid connectivity between on-premises data
centers and AWS?
A. AWS Direct Connect
B. Amazon CloudFront
C. Amazon S3 Transfer Acceleration
D. AWS Lambda
Correct Answer: 🔴 A. AWS Direct Connect
Explanation: Direct Connect provides dedicated private network
connectivity between on-premises infrastructure and AWS, offering
consistent latency and higher throughput than internet-based
VPN.
Q7. A company requires segmentation of workloads within a single VPC using
isolated environments. What is the best design approach?
A. Use multiple Availability Zones
B. Use multiple subnets with route restrictions
C. Use multiple Internet Gateways
D. Use a single subnet with IAM policies
Correct Answer: 🔴 B. Use multiple subnets with route restrictions
Explanation: Subnet segmentation with controlled routing is the
standard approach for workload isolation inside a VPC.
EC2 COMPUTE & SCALING STRATEGIES (Q8–Q14)
Q8. A workload experiences unpredictable traffic spikes. Which AWS service ensures
automatic scaling of EC2 instances?
A. AWS Auto Scaling
B. AWS CloudTrail
C. AWS Config
D. AWS Inspector
Correct Answer: 🔴 A. AWS Auto Scaling
Explanation: Auto Scaling dynamically adjusts EC2 capacity based
