OSI Layers
This OSI layer is responsible for physical transmission of bits.
What is the Physical Layer?
This AWS infrastructure component is a separate geographic area such as us-east-1.
What is the Region?
This cable uses light pulses instead of electrical signals.
What is the Fiber-optic?
This AWS service provides virtual servers.
What is the EC2?
A PC cannot access the network, and its Ethernet cable is unplugged. This is the first thing you should check.
What is Check the physical connection?
This layer uses IP addresses to route packets between networks.
What is the Network Layer?
These isolated networks are called Availability Zones.
What is the Availability Zone?
This common Ethernet cable type uses twisted copper pairs and an RJ-45 connector.
What is the Cat5e/Cat6 Ethernet?
This service provides scalable object storage.
What is the S3?
Two computers are communicating over a network, and the connection needs to be established, maintained, and properly ended after the communication is complete. Which OSI layer is responsible for managing this communication session?
What is the Session Layer (Layer 5)?
TCP and UDP operate at this OSI layer.
What is the Transport Layer?
Within an AWS Region, these provide isolated locations designed to protect applications from failures in another location.
What are Availability Zones?
This cable type is commonly used for long-distance, high-speed networking and resists electromagnetic interference.
What is the Fiber-optic?
This AWS service distributes incoming application traffic across multiple targets.
What is the Elastic Load Balancing?
Two devices on different IP networks need to communicate. This device forwards traffic between them.
What is the Router?
MAC addresses are primarily associated with this OSI layer.
What is the Data Link Layer?
This AWS component controls inbound and outbound traffic for an EC2 instance.
What is the Security Group?
This type of copper Ethernet cable is designed with shielding to reduce electromagnetic interference and is useful in environments with significant electrical noise.
What is shielded twisted-pair (STP) cable?
This AWS managed service makes it easier to set up, operate, and scale relational databases such as MySQL, PostgreSQL, and SQL Server without managing the underlying database servers.
What is Amazon RDS?
A company wants customers around the world to receive website content with lower latency. AWS can cache content closer to users at locations around the world. What AWS infrastructure location is used to deliver this content closer to end users?
What is an AWS Edge Location?
Encryption, compression, and data formatting are functions commonly associated with this OSI layer.
What is the Presentation Layer?
This AWS networking component connects a VPC to the public internet.
What is the Internet Gateway?
This fiber type is designed for high bandwidth over relatively long distances and commonly uses a smaller core than multimode fiber.
What is the Single-mode fiber?
This AWS service allows you to create and manage Kubernetes clusters.
What is the EKS?
A company hosts a web application on EC2. Users report intermittent connection failures. You discover that traffic is being sent directly to individual instances, and one instance is overloaded while others are nearly idle. What AWS service should be introduced to distribute traffic across the instances?
What is Elastic Load Balancing (ELB)?
