Kubernetes

A server in one of Fictional Corp's branch offices is starting to generate warning messages that a piece of hardware is starting to experience issues and may fail soon. The company keeps the server on-premises for that location due to an unreliable Internet connection and thus cannot move it to the cloud because the office heavily relies on that server. Which of the following should a technician perform?

P2P migration

Kathleen has noticed in the configuration management database that a couple of servers are no longer covered by the manufacturer's warranty. The organization has been migrating to the cloud over the past year, so that seemed to be the best place to migrate these to as well. What type of migration would this be considered?

P2V. physical to virtual

Fictional Corp has multiple monitoring systems in place to report various events that occur as soon as they happen. However, they have also tried to design the infrastructure so that it can withstand and compensate for these failures and outages and allow the system to still function so that the users do not notice the failure. Which of the following terms could be used to describe the theory they used when designing their infrastructure?

Resiliency

Fictional Corp is building out a private cloud in their data center. They want to ensure that there are extra resources available in the event that a server fails. Which of the following technologies might they build their cloud upon?

Cluster

Fictional Corp has just finished migrating a number of servers from an on-premises data center to a cloud service provider. However, users are now complaining that they are running much slower than before. Which of the following would NOT be a contributing factor as to why they seem slower?

Amount of disk space provisioned for virtual machines at the CS

Greg is deploying a new application that will originally have 1 terabyte of disk space allocated to storing user files. However, since it is a new application, he is unsure how quickly the disk space may fill up and need to grow to accommodate new files. Which of the following cloud features should he ensure is configured correctly so as not to cause any errors to be displayed to users about the storage space being full?

Auto-scaling

Chris has learned about a technique that he can configure on some of his virtualized systems to help with memory allocation. Using this specific technique, a driver gets installed on each of the virtual machines on a host. That driver allows the host to control a fake process on the virtual machine so that the VM assigns memory to that process. Rather than actually do something with the memory that has been allocated to the process, the host can then assign that memory to another virtual machine so that it can use the memory instead. Which of the following is the best description of the memory reclamation process that Chris is considering using?

Ballooning

Roz is configuring new virtual machines in the company's private cloud. She knows that the virtual machines need a total of 512 GiB of memory. However, the physical machine that she's deploying them to only has 256 GiB installed. Which of the following technologies, when configured correctly, could allow her to deploy the virtual machines to this hardware?

Ballooning

Fictional Corp wants to start migrating a bunch of internal applications to a CSP. However, they are located in a rural area and their only connection option is a T1.

Which of the following is most likely going to be the biggest hurdle for them?

Bandwidth limitations

Jana is trying to optimize the cloud infrastructure of her organization for availability. She wants to ensure that the virtual machines that normally use a certain amount of memory have the ability to use more physical memory up to a predefined level in cases of heavy workloads. Which of the following features should she look at configuring?

Bursting

Fictional Corp has an ecommerce shop where customers can buy widgets directly from them through their website. The shop runs on a virtual machine at a cloud service provider.

Which of the following might describe one of the concepts he could implement in this scenario?

Overcommitment ratio

There have been multiple performance issues with the virtual machines that reside on one of the hosts in the data center at Fictional Corp.
