What does Cross Zone Load Balancing ensure in terms of request distribution?

Each load balancer instance distributes evenly across all registered instances in all Availability Zones.

Requests are distributed based on the geographical location of the user.

Requests are only distributed to the nearest Availability Zone.

Each load balancer instance prioritizes one Availability Zone over others.

How are requests distributed without Cross Zone Load Balancing?

Requests are distributed in the instances of the node of the Elastic Load Balancer within the same Availability Zone.

Requests are distributed evenly across all registered instances in all Availability Zones.

Each load balancer instance sends all requests to a single instance.

Requests are randomly distributed without any specific pattern.

Yes, and it can be disabled at the Target Group level

No, it is not supported by Application Load Balancer

Are there charges for inter Availability Zone (AZ) data with the Application Load Balancer when Cross-Zone Load Balancing is enabled?

No, there are no charges for inter AZ data

Yes, but only if it is disabled

No, but charges apply for intra AZ data

What is the default state of Cross-Zone Load Balancing for Network Load Balancer and Gateway Load Balancer?

Enabled by default with charges

Are there charges for inter AZ data if Cross-Zone Load Balancing is enabled on Network Load Balancer and Gateway Load Balancer?

Yes, you pay charges for inter AZ data if enabled

Yes, but only for Gateway Load Balancer

No, but you pay charges for intra AZ data

Is Cross-Zone Load Balancing enabled by default for Classic Load Balancer?

No, it must be enabled manually

Yes, but charges apply for inter AZ data

Are there charges for inter AZ data if Cross-Zone Load Balancing is enabled on Classic Load Balancer?

No, there are no charges for inter AZ data

Yes, but only if it is disabled

No, but charges apply for intra AZ data

Which of the following entities issues public SSL certificates?

Internet Service Providers (ISP)

How can you manage certificates for the load balancer?

Using ACM (AWS Certificate Manager)

Directly in the load balancer's settings

Through a third-party certificate provider

Is it possible to upload your own certificates for the load balancer?

Yes, as an alternative to using ACM

Yes, but only through AWS support

No, you must use a default certificate

What problem does SNI solve in the context of SSL?

It solves the problem of loading multiple SSL certificates onto one web server.

It encrypts data between the client and the server.

It provides a backup SSL certificate for web servers.

It increases the speed of the SSL handshake.

What does SNI require from the client during the SSL handshake?

The client must indicate the hostname of the target server.

The client must provide a unique SSL certificate.

The client must verify the server's SSL certificate.

The client must encrypt the handshake message.

For which types of load balancers does SNI work?

Both ALB & NLB (newer generation) and CloudFront

ALB and NLB (newer generation) only

What happens if the server cannot find the correct SSL certificate when using SNI?

The server returns the default SSL certificate.

The server terminates the connection immediately.

The server requests a new SSL certificate from the client.

The server retries the SSL handshake.

What is a limitation of the Classic Load Balancer (v1) regarding SSL certificates?

Supports only one SSL certificate

Supports multiple SSL certificates

Does not support SSL certificates

Requires Server Name Indication (SNI) to work

What feature must be used with Application Load Balancer (v2) and Network Load Balancer (v2) to support multiple SSL certificates?

Multiple Classic Load Balancers (CLB)

Single SSL certificate per listener

Multiple Application Load Balancers (ALB)

Which Load Balancer supports multiple listeners with multiple SSL certificates?

Both Application Load Balancer (v2) and Network Load Balancer (v2)

Application Load Balancer (v2) only

Network Load Balancer (v2) only

Can Connection Draining be disabled, and if so, what value should be set?

Yes, by setting the value to -1

What is the primary goal of an Auto Scaling Group (ASG)?

To scale out (add EC2 instances) to match an increased load and scale in (remove EC2 instances) to match a decreased load

To provide a static number of EC2 instances for predictable load

To ensure a fixed cost for cloud services regardless of traffic

To manually adjust the number of EC2 instances on a daily basis

What does an Auto Scaling Group (ASG) automatically do with new instances?

It automatically registers new instances to a load balancer

It deletes new instances immediately to save costs

It sends new instances to a backup storage

It assigns new instances to a standby mode

What happens to an EC2 instance in an ASG when it is terminated due to being unhealthy?

The ASG re-creates an EC2 instance to replace the terminated one

The instance is archived for future analysis

The instance is left running for manual inspection

The instance is permanently removed without replacement

Are there any costs associated with Auto Scaling Groups (ASG) themselves?

No, ASG are free and you only pay for the underlying EC2 instances

Yes, there is a fixed monthly fee for using ASG

Yes, there are variable costs based on the number of instances in the ASG

No, ASG and the underlying EC2 instances are both free of charge

What is the purpose of an Auto Scaling Group in AWS?

To automatically adjust the number of EC2 instances based on predefined conditions and load

To manually adjust the number of EC2 instances based on traffic

To provide a fixed number of EC2 instances regardless of the application load

To scale the storage capacity of EC2 instances

What does the 'Desired Capacity' signify in an Auto Scaling Group in AWS?

The ideal number of EC2 instances that should be running based on the current load

The minimum number of EC2 instances that must be running at all times

The maximum number of EC2 instances that can be launched

The total number of EC2 instances currently running

What happens when an Auto Scaling Group scales out?

It increases the number of EC2 instances

It decreases the number of EC2 instances

It increases the storage capacity of each EC2 instance

It upgrades the EC2 instances to a higher specification

What is indicated by the 'Minimum Capacity' in an Auto Scaling Group in AWS?

The least number of EC2 instances that are maintained at all times

The maximum limit of EC2 instances that can be removed

The number of EC2 instances that are added during a scale out

The initial number of EC2 instances when the Auto Scaling Group is created
