Question 1441Question

An organization is hosting a web application on several Amazon EC2 instances within a public subnet of a Virtual Private Cloud (VPC). The security administrator must configure a stateful network firewall rule at the instance level to permit inbound traffic on port 443 (HTTPS) from any IP address. Which AWS networking component should the administrator modify to meet this requirement?

Show answer & explanation

Answer: Security Group

Answer

Security Group
A security group is the correct component because it operates at the instance level and provides stateful traffic filtering, allowing return traffic automatically without requiring an outbound rule.

Step-by-Step Solution

1
Analyze the requirement for a firewall rule that is stateful and operates at the instance level.
Identify that the component must apply to individual instances (not subnets) and automatically allow return traffic (stateful).
Filtering at the instance level requires instance-level firewalls, and stateful behavior means return traffic does not need explicit rules.
2
Evaluate the options to find which AWS service or configuration meets these characteristics.
A security group acts at the instance level and is stateful. A Network ACL acts at the subnet level and is stateless.
This distinguishes between the two primary firewall features in an Amazon VPC.

Question 1442Question

A smart energy grid operator is deploying a critical monitoring application on AWS. To ensure continuous operation in the event of a localized physical disaster (such as a fire or power outage affecting a data center facility), the architecture must distribute application instances across separate, physically isolated locations that feature independent utility power, cooling, and network connectivity, while still maintaining low-latency network connections between them. Which AWS Global Infrastructure component is designed specifically to meet this requirement?

Show answer & explanation

Answer: Availability Zones

Answer

Availability Zones
Availability Zones are physically distinct locations within an AWS Region. Each Availability Zone is designed to be isolated from failures in other Availability Zones, equipped with independent power, cooling, and physical security, while remaining connected via high-speed, low-latency private fiber optic networks.

Step-by-Step Solution

1
Analyze the requirements: physical isolation of data centers to protect against local disasters (power failure, flooding) combined with low-latency network connections for application synchronization.
Identified the need for localized isolation within a single geographic area that does not introduce high latency.
This rules out cross-region architectures which solve isolation but introduce significant geographic latency.
2
Evaluate the AWS Global Infrastructure components against these requirements.
Availability Zones represent isolated locations within a Region, connected by low-latency networks. Regions are separate geographic areas. Edge Locations cache content.
Understanding the definitions and purposes of each infrastructure component prevents incorrect classification.
3
Select the component that uniquely satisfies both physical separation (independent power/cooling) and low-latency networking.
Availability Zones.
Each Availability Zone is engineered to prevent failures from propagating to other zones, while remaining close enough geographically to support synchronous replication.

Key Concept

Distinction between Regions, Availability Zones, and Edge Locations for High Availability
Question 1443Question

A startup is deploying a two-tier application in a Virtual Private Cloud (VPC) with public and private subnets. The security team must enforce two controls: first, block specific malicious IP addresses from entering the public subnet entirely; second, allow stateful, bidirectional web traffic only on port 443 to the web servers. Which two AWS networking features or configurations should be used to satisfy these security requirements? (Select TWO.)

Select all that apply

Show answer & explanation

Answer: A Network Access Control List (NACL) rule associated with the subnet to deny traffic from the malicious IP addresses; A Security Group rule associated with the web server instances to allow inbound HTTPS traffic

Answer

A Network Access Control List (NACL) rule associated with the subnet to deny traffic from the malicious IP addresses, and a Security Group rule associated with the web server instances to allow inbound HTTPS traffic.
The correct options are a Network Access Control List (NACL) rule to deny traffic at the subnet boundary and a Security Group rule to allow HTTPS traffic at the instance level. NACLs allow explicit deny rules and apply at the subnet level, which blocks malicious traffic before it reaches any instances. Security Groups are stateful and operate at the instance level, allowing return traffic automatically once inbound access on port 443 is granted.

Step-by-Step Solution

1
Determine the control required to block specific malicious IP addresses at the subnet level.
Network ACLs are identified as the correct tool because they operate at the subnet boundary and support explicit deny rules.
Security Groups are allow-only and cannot explicitly deny specific IP addresses.
2
Determine the control required to permit stateful port 443 traffic to the web servers.
Security Groups associated with the instances are identified as the correct tool because they are stateful and allow inbound HTTPS traffic.
Security Groups automatically allow bidirectional return traffic, unlike Network ACLs which are stateless and would require explicit ephemeral port rules in both directions.

Key Concept

The difference between stateful Security Groups operating at the instance level and stateless Network Access Control Lists (NACLs) operating at the subnet level.
Question 1444Question

Which of the following statements regarding the AWS Global Infrastructure are correct? (Select TWO)

Select all that apply

Show answer & explanation

Answer: Deploying application components across multiple Availability Zones within a single AWS Region provides high availability and fault tolerance against localized failures.; Choosing a specific AWS Region helps meet data residency and compliance requirements by keeping data physically within that region's geographic boundaries.

Answer

Deploying application components across multiple Availability Zones within a single AWS Region provides high availability and fault tolerance against localized failures; and choosing a specific AWS Region helps meet data residency and compliance requirements by keeping data physically within that region's geographic boundaries.
Deploying across multiple Availability Zones within a Region ensures protection from localized disasters because they are isolated from each other physically and utility-wise. Selecting a specific AWS Region keeps customer data physically located within that Region, directly addressing data sovereignty requirements.

Step-by-Step Solution

1
Analyze the high availability requirement against localized failures.
Availability Zones (AZs) are designed to provide physical isolation within a Region, making them the correct infrastructure component for localized disaster resilience.
AZs are separate physical locations with redundant power, networking, and connectivity within an AWS Region.
2
Analyze the compliance and data residency requirement.
AWS Regions define the geographic boundary of where data resides.
Customers choose the AWS Region in which their data is stored, and AWS guarantees that the data remains within that Region unless the customer explicitly configures replication elsewhere.

Key Concept

AWS Regions provide geographic boundaries for data sovereignty, while Availability Zones within a Region provide fault isolation and high availability.
Question 1452Question

A small development team is setting up their AWS environment. They require a support plan that allows any of their five team members to independently open technical support cases with AWS. What is the minimum AWS Support plan that meets this requirement?

Question 1453Question

A company is hosting a database instance in a private subnet of a Virtual Private Cloud (VPC). The database should only accept incoming traffic from web application servers running in a public subnet of the same VPC. To implement this restriction, the company wants to deploy a stateful firewall that controls inbound and outbound traffic at the individual instance level. Which AWS network security feature should be used to meet these requirements?

Show answer & explanation

Answer: Security groups

Answer

Security groups
Security groups act as a stateful firewall for EC2 instances, controlling inbound and outbound traffic at the instance level. They allow you to specify permit rules, and because they are stateful, any allowed inbound traffic is automatically allowed outbound, satisfying the requirement to secure individual database instances.

Step-by-Step Solution

1
Identify the level at which the firewall must operate based on the requirements.
The requirement specifies controlling traffic at the individual instance level, not the subnet level.
This distinguishes between security groups (which operate at the instance level) and Network ACLs (which operate at the subnet level).
2
Evaluate the statefulness requirement.
The scenario requires a stateful firewall.
Security groups are stateful, meaning allowed inbound traffic automatically permits return outbound traffic. Network ACLs are stateless and require explicit rules in both directions.

Key Concept

Security groups act as stateful firewalls at the instance level, whereas Network ACLs act as stateless firewalls at the subnet level.

Question 1457Question

A company's finance team is attempting to track cloud costs using a user-defined cost allocation tag named 'ProjectID' and the AWS-generated cost allocation tag 'aws:createdBy'. Although developers have applied these tags to several active Amazon EC2 instances, the tags are not appearing in the company's billing reports or AWS Cost Explorer. Which of the following describes the correct action and behavior required to make these tags visible on the billing reports?

Show answer & explanation

Answer: Activate both the 'ProjectID' and the 'aws:createdBy' tags within the AWS Billing and Cost Management console, which will cause them to appear on future billing reports without retroactively updating historical costs.

Answer

Activate both the 'ProjectID' and the 'aws:createdBy' tags within the AWS Billing and Cost Management console, which will cause them to appear on future billing reports without retroactively updating historical costs.
Cost allocation tags, whether user-defined or AWS-generated, must be activated in the AWS Billing and Cost Management console before they can be used to track costs in reports or Cost Explorer. These tags do not apply retroactively, meaning they will only track cost data from the time of activation forward.

Step-by-Step Solution

1
Identify that cost allocation tags must be explicitly enabled for billing tracking.
Applying tags directly to resources makes them available for search/organization, but not for cost tracking.
AWS requires activation so that it knows which tag keys to include in the billing datasets and reports.
2
Select the correct location for tag activation.
Both user-defined ('ProjectID') and AWS-generated ('aws:createdBy') tags must be activated in the Billing and Cost Management console.
This is the single centralized place where billing-related tag schemas are managed.
3
Determine the temporal behavior of cost allocation tags.
Activated tags only apply from the time of activation forward.
AWS does not recalculate historical billing files dynamically for retroactive tag applications.
