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?

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?

A new record-keeping application for employees to track customer orders must be deployed to a company's existing infrastructure. The host servers reside in a data center in a different country to where the majority of users work. The new network configuration for the database server is: •IP:

10.8.32.10

• Subnet Mask: 255.255.255.0

• Hostname: CustOrd423320458-Prod-010

• MAC: 18-46-AC-6F-F4-52.

The performance of the client-side application is a priority due to the high demand placed on it by employees. Which area should the team consider in terms of impact to application performance due to the planned deployment?

jitter

decreased bandwidth

latency

connectivity loss

Question 300

Two Elasticsearch database servers use bidirectional asynchronous data replication Both servers accept writes from clients The design must meet these requirements:

• The cluster must survive if a fault occurs that causes the network connection to go down between nodes

• The data must remain consistent if communication between nodes fails.

• The data must be spread evenly across all nodes in the cluster.

Which design approach must be used to meet the requirements?

Set the initial voting configuration to force a specific node as the master.

Scale the master nodes down to a single node.

Set the minimum_master_nodes to 2 in the configuration.

Add a third cluster node to provide majority votes.
