Elastic Load Balancers Flashcards
A company has a web application hosted on a fleet of EC2 instances located in two Availability Zones that are all placed behind an Application Load Balancer. As a Solution’s Architect, you have to add a health check configuration to ensure your application is highly-available. Which health checks will you implement?
HTTP or HTTPS health check
A TCP health check is only offered by which load balancers?
Network Load Balancers and Classic Load Balancers
An HTTP or HTTPs health check is only allowed on which type of Load Balancer?
Application Load Balancer
When you use AWS WAF on Amazon Cloudfront, your rules run where?
In all AWS Edge locations
____________ is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to an Amazon API Gateway API, Amazon CloudFront or an Application Load Balancer.
AWS WAF
AWS WAF lets you choose what 3 behaviors?
- Allow all requests except the ones you specify
- Block all requests except the ones you specify
- Count the requests that match the properties that you specify.
______________ is a threat detection service that continuously monitors for malicious activity and unauthorized behavior to protect your AWS accounts and workloads.
Amazon GuardDuty
______________ simplifies you AWS WAF and AWS Shield Advanced administration and maintenance tasks across multiple accounts and resources.
AWS Firewall Manager
What kind of load balancer operates at the request level (layer 7), routing traffic to targets (EC2 instances, containers, IP addresses, and Lambda functions) based on the content of the request?
Application Load Balancer
What kind of load balancer provides advanced request routing targeted at delivery of modern application architectures, including micro-services and container-based applications?
Application Load Balancers
What kind of load balancer simplifies and improves the security of your application by ensuring that the latest SSL/TLS ciphers and protocols are used at all times?
Application Load Balancers
If your application is composed of several individual services, an _____________ can route a request to a service based on the content of the request such as Host field, Path URL, HTTP header, HTTP method, Query string,or Source IP address.
Application Load Balancer
_______________ can route and load balancer gRPC traffic between microservices or between gRPC-enabled clients and services. This will allow customers to seamlessly introduce gRPC traffic management in their architectures without changing any of the underlying infrastructure on their clients or services.
Application Load Balancers
The gRPC protocol is at which layer of the OSI model?
Layer 7
____________ optimizes application performance by routing user traffic to the congestion-free, redundant AWS global network instead of the public internet.
AWS Global Accelerator
___________ routing allows you to route a client request based on the URL path of the HTTP header.
Path-based routing
You can use ___________ to define rules that forward requests to different target groups based on the URL in the request (also known as path based routing)
Path conditions
_____________ routing defines rules that forward requests to different target groups based on the hostname in the host header instead of the URL.
Host-based Routing
What kind of load balancer is used for applications that need extreme network performance and static IP? It doesn’t support path-based routing.
Network Load Balacer
When ____________ is enabled, each load balancer node distributes traffic cross the registered targets in all enabled Availability Zones. When disabled, each load balancer node distributes traffic only across the registered targets in its Availability Zone.
Cross-zone load balancing
_____________ is a feature in Amazon VPC that provides network administrators with an automated IP management workflow.
Amazon VPC IP Address Manager (IPAM)
The _____________ feature lets you create connections between your on-premises networks through the AWS global network backbone.
AWS Direct Connect SiteLink
What is the Amazon CloudWatch service that monitors the changes to your Application Load Balancer itself and the actual IP traffic that it distributes to the target groups?
Amazon EventBridge
What type of Load Balancer should you use for TCP, TLS, and UDP protocols?
Network Load Balancer
What type of Load Balancer should you use for HTTP, HTTPS, and WebSocket protocols?
Application Load Balancer
