Wavelength

Question 1

Wavelength

Answer 1

is the AWS infrastructure used to run workloads that require ultra-low latencies over mobile networks.

Question 2

How can Wavelength be used?

Answer 2

Wavelength Zones can be used to extend an Amazon VPC in order to run ultra-low latency applications that use the same AWS services, APIs, tools, and functionalities.

Question 3

What compute instances are supported by Wavelength?

Answer 3

Wavelength Zones support a wide range of compute instances for general purpose, gaming, and machine learning inference.

Question 4

What storage options are supported by Wavelength?

Answer 4

Supports persistent block storage to provide a snapshot, encryption, and restore capabilities without any performance impact.

Question 5

How do you get connectivity to 5G networks?

Answer 5

Connectivity to 5G networks using VPC and Carrier Gateway.

Question 6

True/False. Various AWS management and monitoring tools to run and manage workloads in Wavelength Zones.

Answer 6

True.

Question 7

Wavelength use cases

Answer 7

-Create and distribute augmented/virtual reality (AR/VR) apps, as well as HD live video streaming.
-Use AI and ML-powered video and image analytics at the edge to accelerate 5G applications in medical diagnostics, retail, and smart manufacturing settings.
-With near-real-time communication between automobiles and the cloud, you’ll be able to create advanced driver assistance, autonomous driving, and in-vehicle entertainment experiences.

Question 8

Wavelength Zone (WZ)

Answer 8

A logical extension of the Region. It is where the Wavelength infrastructure is deployed and is managed by the Region’s control plane.

Question 9

When do you use WZs?

Answer 9

Use WZs for application components that require ultra-low latency, enhanced bandwidth, or improved service quality across 5G mobile networks.

Question 10

Best design for the most scalable, robust, and cost-effective alternatives for components?

Answer 10

To give the most scalable, robust, and cost-effective alternatives for components, AWS recommends that you design the edge applications in a hub and spoke model with the Region.

Question 11

How to handle latency-sensitive applicaitons?

Answer 11

For latency-sensitive applications, you need to have multiple WZs.

Question 12

How do you discover the closest EZ endpoint?

Answer 12

To discover the closest WZ endpoint, you must register the EC2 instance with a discovery service such as AWS Cloud Map.

Question 13

What is recommended for data and app replication?

Answer 13

For data and app replication, AWS recommends you use an AZ in a different Region as a failover zone.

Question 14

True/False. Apps running on 4G/LTE mobile phones and devices connected to 4G/LTE networks can also connect to Wavelength Zones’ application servers.

Answer 14

True.

Question 15

Wavelength Application

Answer 15

An application that you run on an AWS resource in a WZ

Question 16

Carrier Gateway

Answer 16

-Provides connectivity between WZ and telecommunication carrier.
-Enables inbound traffic from a carrier network in a specific location, as well as outbound traffic to the carrier network and the internet.
-Supports IPv4 traffic.
-Only available for VPCs with WZ subnets.
-To assign a network interface, use a carrier IP address from the network border group.

Question 17

True/False. You cannot create AWS compute, storage services, and carrier gateways in WZs.

Answer 17

False. You can create AWS compute, storage services, and carrier gateways in WZs.

Question 18

Network requirements for Wavelength?

Answer 18

You’ll also need VPC, Subnet, and Network Border Group to be able to leverage the 5G edge computing infrastructure of AWS Wavelength.

Question 19

What do you need to manage your resources and WZs?

Answer 19

-AWS Management Console
-AWS CLI
-AWS SDKs

Question 20

How is Wavelength priced?

Answer 20

-Prices for AWS resources in WZs will differ from those in the parent region.
-In WZs, EC2 instances are only available on demand.
-Wavelength Zones can be used with your Instance Savings Plan.
