Question 1

What are the three components of Amazon EC2 Auto Scaling?
✅ Launch template, scaling policies, EC2 Auto Scaling group
❌ Scaling policies, security group, EC2 Auto Scaling group
❌ Security group, instance type, key pair
❌ AMI ID, instance type, storage

Explanation:
EC2 Auto Scaling consists of:
1️⃣ A Launch Template (configuration),
2️⃣ Scaling Policies (rules for scaling), and
3️⃣ An Auto Scaling Group (group of EC2 instances).

Question 2

Which of the following features are included in Elastic Load Balancing (ELB)?
✅ A and C (Automatic scaling, Integration with Amazon EC2 Auto Scaling)
❌ A and B
❌ Integration with Amazon RDS
❌ Only Automatic scaling

Explanation:
ELB automatically distributes traffic and integrates tightly with Auto Scaling, dynamically adding or removing EC2 instances.

---

Question 3

True or False: When using ELB with an Auto Scaling group, it is not necessary to manually register EC2 instances.
✅ True
❌ False

Explanation:
When ELB integrates with Auto Scaling, instances are automatically registered or deregistered as the group scales.

---

Question 4

An application must route traffic based on the URL path. Which ELB type should be used?
✅ Application Load Balancer
❌ Classic Load Balancer
❌ Network Load Balancer
❌ Target Load Balancer

Explanation:
Application Load Balancer (ALB) works at Layer 7 (HTTP/HTTPS) and supports path-based routing rules.

---

Question 5

What are the two ways that an application can be scaled?
✅ Vertically and horizontally
❌ Diagonally and vertically
❌ Horizontally and diagonally
❌ Independently and vertically

Explanation:
Vertical scaling = increasing instance size; Horizontal scaling = adding more instances.

Question 6

Which elements in CloudWatch dashboards are used to view and analyze metrics?
✅ Widgets
❌ Metrics
❌ Icons
❌ Components

Explanation:
Widgets visualize metrics and logs on CloudWatch Dashboards for analysis.

What are the possible states of a metric alarm in Amazon CloudWatch?
✅ OK, ALARM, INSUFFICIENT_DATA
❌ OK, ALERT, INSUFFICIENT_DATA
❌ OK, ALARM, NOT_AVAILABLE
❌ OK, ALERT, NOT_AVAILABLE

Explanation:
A CloudWatch alarm can be in one of three states:

• OK – normal,

Question 8

What kind of data can a company collect with VPC Flow Logs?
✅ Data about network traffic that comes into and out of a VPC
❌ Malicious activity
❌ AWS resource configurations
❌ Compliance info

Explanation:
VPC Flow Logs capture IP traffic information (source, destination, ports) for network monitoring and troubleshooting.

---

Question 9

What is a benefit of monitoring on AWS?
✅ Monitoring recognizes security threats and events.
❌ Monitoring creates overhead.
❌ Monitoring decreases performance.
❌ Monitoring increases agility only.

Explanation:
Monitoring (via CloudWatch, CloudTrail) helps detect anomalies, security events, and performance issues proactively.

---

Question 10

True or False: When using serverless services, users might not need to configure networking components like VPCs or subnets.
✅ True
❌ False
