The CSA needs to install a patch on 58 virtual server instances during the Friday evening maintenance window. Which of the following is the MOST efficient way to get the patches installed?

• A.Connect the server instances to the Internet to download the patch automatically.
• B.Use the patch management tool to automate and orchestrate the patch installation.

A cloud administrator for a customer's environment must ensure the availability of critical applications. The cloud provider hosting the infrastructure lost power, and the environment was down for four hours. Which of the following solutions is MOST suitable for ensuring availability of critical applications?

• A.Install services at alternate sites.
• B.Move services to a third-party environment.
• C.Deploy additional services to edge sites.

An administrator needs to deploy a new release of an application in a way that allows a quick rollback to the previous version of the application. Which of the following is the BEST strategy to apply?

• A.Deploy the application to a set of servers in small batches. If a rollback is necessary, restore the previous deployment from snapshots or backups.
• B.Deploy the application to the servers in a backup datacenter or secondary cloud deployment. Shut down the servers in the primary datacenter, forcing all traffic to the failover location. If a rollback is necessary, restart the primary environment and shut down the secondary environment.
• C.Deploy the application to all servers in the datacenter or cloud environment. If a rollback is necessary, undeploy the application and deploy the previous version.
• D.Deploy the application to a subset of servers that expose the new application. Direct all traffic to these servers. If a rollback is necessary, redirect all traffic to the previous subset of servers.

A cloud engineer is using a hosted service for aggregating the logs for all the servers in a public cloud environment. Each server is configured via syslog to send its logs to a central location. A new version of the application was recently deployed, and the SaaS server now stops processing logs at noon each day. In reviewing the system logs, the engineer notices the size of the logs has increased by 50% each day. Which of the following is the MOST likely reason the logs are not being published after noon?

• A.The syslog service is not running on the servers.
• B.There is a cloud service provider outage.
• C.The logging directory does not have sufficient storage space.
• D.The data limit has been exceeded at the SaaS provider.
