Network functions have been virtualized in private cloud space A number of successful user functionality tests were executed and a load test was run using less than 100 users. The virtual network element was added into a pool of similar physical and virtual network functions. Each function is licensed to handle 1.2 million subscribers. However, following the pool migration, less than 10% of the users of the virtualized network element are able to browse. Which of the following is the BEST approach to troubleshoot the issue?

1. Block the virtual network element from taking new traffic. Once isolated, schedule a load test and review engineering plans

2. Keep the virtual network element in the pool and start troubleshooting. The engineering capacity plan needs to be reviewed with appropriate planning organization

3. Orchestrate another installation of second or third virtual network function, as needed, to add temporary capacity to the pool

4. Check on the IP address pool and ensure the virtual functions have the same number of IP addresses available to accommodate the subscribers

Last month, a cloud engineer updated all the linux servers to disallow telnet communication by updating the firewall and uninstalling the application. However, it was recently discovered that three of the servers had the telnet port and application installed and configured. Which of the following is the BEST way to implement and maintain the change?

1. Implement a process to rebuild all the linux servers on a weekly basis

2. Disable the local administrator accounts and change all the user passwords

3. Configure a configuration management system to update all linux servers

4. Review the system logs to determine who made the changes and disable those accounts

A cloud administrator at a media company is creating a backup strategy for large file servers hosted in a public cloud. These servers are used to host large video projects that are edited frequently, but new files are created rarely. The cloud provider bills on ingress and egress data traffic. If the cloud administrator wants to minimize costs on backups, which of the following backup types would be BEST?

1. Clone

2. Incremental

3. Differential

4. Full

A programmer is building a new web application for a clients public cloud infrastructure. The client has requested that the web application stay available even in the event of a regional outage at the cloud provider. Which of the following would BEST address these availability requirements?

1. Cloud bursting

2. DNS failover

3. Clustering

4. Autoscaling

Click the exhibit button. A cloud performance engineer is asked to review the usage and resource utilization from last quarter and then provide analysis and a recommendation. The data shown in the exhibit is collected and plotted for analysis. In addition to investigating the alarms, which of the following is the BEST recommendation for the engineer to provide?

1. Migrate to different cloud provider to improve performance

2. Monitor utilization to ensure it does not exceed 80%

3. Enable hyperthreading and add memory to allow for growth

4. Add more CPUs to lower the utilization
