SIMULATION

A company has decided to scale its e-commerce application from its corporate datacenter to a commercial cloud provider to meet an anticipated increase in demand during an upcoming holiday.

The majority of the application load takes place on the application server under normal conditions. For this reason, the company decides to deploy additional application servers into a commercial cloud provider using the on-premises

orchestration engine that installs and configures common software and network configurations.

The remote computing environment is connected to the on-premises datacenter via a site-to-site IPSec tunnel. The external DNS provider has been configured to use weighted round-robin routing to load balance connections from the Internet.

During testing, the company discovers that only 20% of connections completed successfully.

An organization is running a database application on a SATA disk, and a customer is experiencing slow performance most of the time. Which of the following should be implemented to improve application performance?

A. Increase disk capacity

B. Increase the memory and network bandwidth

C. Upgrade the application

D. Upgrade the environment and use SSD drives

A cloud administrator is setting up a DR site on a different zone of the same CSP. The application servers are replicated using the VM replication, and the database replication is set up using log shipping. Upon testing the DR site, the application servers are unable to access the database servers. The administrator has verified the systems are running and are accessible from the CSP portal.

Which of the following should the administrator do to fix this issue?

A. Change the database application IP

B. Create a database cluster between the primary site and the DR site

C. Update the connection string

D. Edit the DNS record at the DR site for the application servers

Which of the following will MOST likely be executed in the cloud solution to meet security requirements?

A. Performance testing

B. Regression testing

C. Vulnerability testing

D. Usability testing

A systems administrator is reviewing two CPU models for a cloud deployment. Both CPUs have the same number of cores/threads and run at the same clock speed. Which of the following will BEST identify the CPU with more computational power?

A. Simultaneous multithreading

B. Bus speed

C. L3 cache

D. Instructions per cycle
