An Etag header is included in the HTTP response for an API resource. What are two benefits of usingthe value of the Etag for future interactions involving the same API resource? (Choose two.)
caching and optimization of response payloads
creating conditional requests
categorizing and comparing this API resource with others
checking the integrity of the resource
requesting the list of operations authorized for this resource
Explanation:
• The ETag HTTP response header is an identifier for a specific version of a resource. It lets caches bemore efficient and save bandwidth, as a web server does not need to resend a full response if thecontent has not changed. Additionally, etags help prevent simultaneous updates of a resource fromoverwriting each other ("mid-air collisions").
• The ETag or entity tag is part of HTTP, the protocol for the World Wide Web. It is one of severalmechanisms that HTTP provides for Web cache validation, which allows a client to make conditionalrequests.
An organization manages a large cloud-deployed application that employs a microservices architecture. No notable issues occur with downtime because the services of this application are redundantly deployed over three or more data center regions. However, several times a week reports are received about application slowness. The container orchestration logs show faults in a variety of containers that cause them to fail and then spin up brand new.
Which action must be taken to improve the resiliency design of the application while maintaining current scale?
Update the base image of the containers.
Test the execution of the application with another cloud services platform.
Increase the number of containers running per service.
Add consistent "try/catch(exception)" clauses to the code.
A network operations team is using the cloud to automate some of their managed customer and branch locations. They require that all of their tooling be ephemeral by design and that the entire automation environment can be recreated without manual commands. Automation code and configuration state will be stored in git for change control and versioning. The engineering high-level plan is to use VMs in a cloud- provider environment then configure open source tooling onto these VMs to poll, test, and configure the remote devices, as well as deploy the tooling itself.
Which configuration management and/or automation tooling is needed for this solution?
Ansible
Ansible and Terraform
NSO

A client is written that uses a REST API to interact with a server. Using HTTPS as the transport, anHTTP request is sent and received an HTTP response. The response contains the HTTP responsestatus code: 503 Service Unavailable.
Which action is the appropriate response?
Add an Authorization header that supplies appropriate credentials and sends the updated request.
Resend the request using HTTP as the transport instead of HTTPS.
Add an Accept header that indicates the content types that the client understands and send the updated request.
Look for a Retry-After header in the response and resend the request after the amount of time indicated.
