A company needs to run a database backup script every night at 2:00 AM. The script takes about 2 minutes to execute, and the company wants to minimize costs by only paying for the exact compute time used during execution, without maintaining any running servers. Which AWS compute service is best suited to meet this requirement?

Cevabı ve açıklamayı göster

Cevap: AWS Lambda

Cevap

AWS Lambda is the most appropriate service because it runs code in response to events and charges only for the compute time consumed, making it cost-effective for short, scheduled scripts without the need to manage servers.
AWS Lambda is the correct choice because it is a serverless compute service that executes code in response to event triggers, such as a scheduled Amazon CloudWatch event. It scales automatically and charges only for the milliseconds of compute time used during execution, eliminating the cost of idle server time.

Adım Adım Çözüm

1
Analyze the workload requirements
The workload is a short-running task (2 minutes) that runs once per day on a schedule, and the business wants to minimize management overhead and costs.
Understanding the execution duration and scheduling frequency helps identify the optimal compute tier.
2
Compare AWS compute services against the requirements
AWS Lambda allows running code serverlessly and paying only for the 2 minutes of execution. Services like Amazon EC2 or Amazon Lightsail require running instances that incur continuous hourly or monthly charges.
Evaluating against AWS billing models ensures the solution is cost-effective and serverless.

A logistics company is setting up its virtual private cloud (VPC) on AWS. The network administrator needs to ensure that return traffic for allowed inbound requests to EC2 instances is permitted automatically without needing explicit outbound rules. However, they also need a secondary layer at the subnet boundary that can explicitly block all traffic from a known list of scanner IP addresses. Which network security configurations should be used to accomplish this?

Cevabı ve açıklamayı göster

Cevap: Configure a stateful Security Group at the instance level to allow return traffic automatically, and a stateless Network ACL at the subnet level to block the scanner IPs.

Cevap

Configure a stateful Security Group at the instance level to allow return traffic automatically, and a stateless Network ACL at the subnet level to block the scanner IPs.
The correct option correctly identifies the roles and behaviors of Security Groups and Network ACLs. Security Groups are stateful firewalls that run at the instance level, meaning that return traffic is automatically allowed regardless of outbound rules. Network ACLs operate at the subnet level and are stateless, meaning they evaluate traffic in both directions separately and support explicit deny rules to block specific IP addresses.

Adım Adım Çözüm

1
Analyze the requirement for automatic return traffic without outbound rules.
Identify that a stateful firewall is required at the instance level, which is the definition of an AWS Security Group.
Security Groups are stateful, meaning any inbound traffic allowed is automatically permitted to flow outbound.
2
Analyze the requirement to block specific IP addresses at the subnet boundary.
Identify that a subnet-level firewall supporting deny rules is required, which points to a Network Access Control List (NACL).
Network ACLs operate at the subnet level, are stateless, and allow both explicit allow and deny rules.

Cevabı ve açıklamayı göster

Cevap: Create an IAM group for the analysts and attach an IAM policy that grants read-only access to S3 and query permissions for Athena.; Place the individual IAM users of the analysts into the new IAM group and remove any directly attached AdministratorAccess policies.

Cevap

Creating a dedicated IAM group with a policy that allows only S3 and Athena access, and moving the analysts' individual IAM users into that group while removing their administrator policies.
The correct actions involve applying the principle of least privilege. By creating an IAM group with a policy restricted to the required Amazon S3 and Amazon Athena permissions, and placing individual IAM users into this group while stripping their admin rights, the company ensures that analysts have only the access necessary for their job functions. Managing access at the group level simplifies administration and aligns with AWS security best practices.

Adım Adım Çözüm

1
Define the required permissions using an IAM policy that allows read-only access to Amazon S3 and query execution in Amazon Athena, and attach it to a newly created IAM group.
Access is grouped under a single administrative boundary corresponding to the analysts' job role.
Grouping permissions makes management easier and adheres to the principle of least privilege.
2
Assign the analysts' individual IAM users to the IAM group and detach any previously assigned direct policies, such as administrative access.
Analysts lose broad access and are restricted only to the permissions granted by the group policy.
This implements the transition to least privilege access controls safely.

An enterprise retail organization is migrating its online checkout application to the AWS Cloud. To ensure that the application remains available even during a localized physical data center outage, the cloud engineer deploys Amazon EC2 instances across two different Availability Zones and configures an Application Load Balancer to route traffic. Additionally, they deploy Amazon RDS in a Multi-AZ configuration to automate database failover. Which AWS Cloud design principle is directly demonstrated by this implementation?

Cevabı ve açıklamayı göster

Cevap: Design for failure

Cevap

Design for failure
The correct answer is design for failure. AWS infrastructure is distributed globally across regions and Availability Zones. The 'design for failure' principle guides cloud architects to assume that components (like instances, disks, or even entire data centers) will eventually fail. Deploying resources across multiple Availability Zones and configuring database failover automatically shifts traffic to running nodes when a disruption occurs, implementing this design principle in practice.

Adım Adım Çözüm

1
Analyze the architectural changes in the scenario.
The application deploys virtual machines (EC2 instances) across multiple Availability Zones with a load balancer and uses Multi-AZ database replication with automated failover.
This establishes that the design is specifically planning for the potential loss of an entire physical data center (Availability Zone) and automating the recovery process.
2
Evaluate the architectural changes against the core AWS design principles.
Planning for components to fail and establishing automatic recovery paths aligns directly with the 'design for failure' principle.
Designing for failure means assuming everything will eventually fail, prompting architects to build redundancy and automated self-healing mechanisms into the system.

A food delivery service is designing a real-time tracking application. The application must store and query the geographic coordinates (x,y)(x, y) of active delivery couriers. These coordinate updates occur every 33 seconds for each courier. The application needs to query this dataset to find the nearest couriers to a restaurant, requiring under 11 millisecond latency. The location data is temporary, and the service must guarantee that any record older than 55 minutes is immediately removed to prevent stale tracking and excessive storage usage. Which AWS database service is the most appropriate solution for this application?

Cevabı ve açıklamayı göster

Cevap: Amazon ElastiCache (Redis OSS)

Cevap

Amazon ElastiCache (Redis OSS)
Amazon ElastiCache (Redis OSS) is the correct service because it is an in-memory data store capable of sub-millisecond latency. It features native geospatial indexing to find nearby coordinates and supports immediate, synchronous key expiration (TTL) to guarantee that location data older than 55 minutes is removed instantly.

Adım Adım Çözüm

1
Evaluate the latency requirement of the workload.
The application requires under 11 millisecond latency for geospatial queries.
This requirement rules out traditional disk-based database services like Amazon RDS, Amazon DynamoDB, and Amazon DocumentDB, pointing towards an in-memory database solution.
2
Analyze the data expiration (TTL) constraints.
Records older than 55 minutes must be removed immediately to prevent stale courier tracking.
Amazon DynamoDB's TTL is asynchronous and can take up to 4848 hours to purge data, making it unfit. Amazon ElastiCache (Redis OSS) supports immediate key eviction upon expiration.
3
Examine the data access patterns.
The application needs to query geographic coordinates to find the nearest couriers to a point.
Amazon ElastiCache (Redis OSS) natively supports geospatial commands like GEOSEARCH, enabling efficient, real-time spatial calculations in-memory.

A company needs to grant an external auditing firm temporary, read-only access to the AWS CloudTrail logs stored in their AWS account. The access must expire automatically after a set period. Which configuration should the company use to grant this access according to AWS security best practices?

Cevabı ve açıklamayı göster

Cevap: Create an IAM role with a read-only policy that the auditing firm can assume.

Cevap

Create an IAM role with a read-only policy that the auditing firm can assume.
Creating an IAM role with a read-only policy is the correct approach. IAM roles do not have permanent credentials; instead, they provide temporary security credentials that expire automatically, which satisfies the requirement for temporary, time-limited access without the risk of long-term credentials.

Adım Adım Çözüm

1
Analyze the requirements for external access.
The external auditing firm requires read-only access to AWS CloudTrail logs, and the access must be temporary and automatically expire.
This establishes the constraints of the required solution: read-only permissions and temporary credentials.
2
Evaluate the AWS Identity and Access Management (IAM) entities.
IAM roles provide temporary security credentials that rotate automatically and expire, which matches the need for temporary access. IAM users, by contrast, rely on long-term credentials like passwords or access keys, which are not suitable for temporary third-party access.
This identifies the correct mechanism to fulfill the temporary access requirement while adhering to security best practices.
3
Verify compliance with the Shared Responsibility Model and root user best practices.
Sharing root user credentials is a major security violation, and asking AWS Support to manage access permissions violates the customer's responsibility for security 'in' the cloud. Configuring an IAM role is the customer's responsibility and aligns with best practices.
This confirms that alternative options violate fundamental AWS security and responsibility principles.
