An administrator needs to adhere to the following requirements when moving a customer's data to the cloud:

• The new service must be geographically dispersed.
• The customer should have local access to data
• Legacy applications should be accessible.

Which of the following cloud deployment models is most suitable?

A cloud networking engineer is troubleshooting the corporate office's network configuration. Employees in the IT and operations departments are unable to resolve IP addresses on all devices, and the IT department cannot establish a connection to other departments' subnets. The engineer identifies the following configuration currently in place to support the office network:



Each employee needs to connect to the network with a maximum of three hosts. Each subnet must be segregated, but the IT department must have the ability to communicate with all subnets. Which of the following meet the IP addressing and routing requirements? (Select two).

A. Modifying the subnet mask to 255 255 254.0 for IT and operations departments

B. Configuring static routing to allow access from each subnet to 10.1.40.1

C. Modifying the BYOD policy to reduce the volume of devices that are allowed to connect to the corporate network

D. Configuring static routing to allow access from 10.1.30.1 to each subnet

E. Combining the subnets and increasing the allocation of IP addresses available to support three hosts for each employee

F. Modifying the subnet mask to 255.255.255.128 for the IT and operations departments

An engineer made a change to an application and needs to select a deployment strategy that meets the following requirements:

D. Web sockets

A cloud engineer is designing a cloud-native, three-tier application. The engineer must adhere to the following security best practices:

• Minimal services should run on all layers of the stack.
• The solution should be vendor agnostic.
• Virealization could be used over physical hardware.

Which of the following concepts should the engineer use to design the system to best meet these requirements?

A. Virtual machine

B. Micro services

C. Fan-out

D. Cloud-provided managed services

A company uses containers stored in Docker Hub to deploy workloads (or its laaS infrastructure. The development team releases changes to the containers several times per hour. Which of the following should a cloud engineer do to prevent the proprietary code from being exposed to third parties?

A. Use laC to deploy the laaS infrastructure.

B. Convert the containers to VMs.

C. Deploy the containers over SSH.

D. Use private repositories for the containers.
