Highlight ways you kept applications and services available during the process, such as migrating workloads off of troubled server hardware. We're in the process of virtualizing the server fleet. How would you manage this project? Don't be fooled by this type of interview question. Virtualization is certainly an important technology and sysadmins should have a detailed knowledge of hypervisors, so highlight your expertise using common hypervisors, or managing mixed -- physical and virtualized -- as well as remote systems.
But don't stop there. This question invites a discussion of strategy rather than technology. In a leadership role, how would you justify, organize and execute the deployment of a new technology in the data center? This is how the IT department delivers the cost-effective services that keep businesses competitive.
This is an opportunity to stand out as manager material. Talk about evaluating the hypervisors, how you determine which workloads to virtualize, performance testing and workload protection decision-making processes, and how to get the most user and business benefit from virtualization.

6 Interview Questions for Systems Administrators
Interview questions are exclusively designed for job seekers to assist them in clearing interviews. Question 1. What Is Virtualization in General? Answer : Virtualization, in computing, is the creation of a virtual rather than actual version of something, such as a hardware platform, operating system, a storage device or network resources. Question 2. Answer : Server Storage Desktop Application. Question 3. Cuts down on maintenance costs with less physical servers.
It offers increased security as the virtual servers are independent of one another. Business continuity with high availability of your applications as another server can take over when one fails. Question 4. Answer : Hosted virtualization products run the virtualization software on top of the host OS, which introduces additional overhead and a longer code execution path for the virtual machines VMs that run in the hosted virtualization environment. In contrast, hypervisor-based products such as ESX Server and Hyper-V are designed to run the hypervisor directly on the system hardware.
Question 5. Answer : Type 1-A technique used where the virtualization layer runs directly on the host's hardware. The host and guest operating systems run on another level above the hypervisor. Type 2-The virtualization layer runs on top of an existing operating system and is in effect a hosted application.

Answer : Hyper-V R2 has performance improvements in these ares:. Question A 2 GHz or faster processor is recommended; minimum supported is 1 GHz. Answer : Windows Server , Hyper-V supported up to 16 logical processors. Update KB for Server added support for up to 24 logical processors. However, a virtual machine can use only as much memory as the maximum amount supported by the guest operating system. For example, if you specify 64 GB for a virtual machine running a guest operating system that supports a maximum of 32 GB, the virtual machine cannot use more than 32 GB.
What's Microsoft Hyper-v Server? Answer : Hyper-V consists of a bit hypervisor that can run bit and bit virtual machines concurrently. Hyper-V virtualization works with single and multi-processor virtual machines and includes tools such as snapshots, which capture the state of a running virtual machine. Answer : There are three types of virtual networks that you can connect to in Hyper-V:.

You should use Private Virtual Networks when you want complete isolation from both the Host operating system and the physical network. Answer : One for management of the Host operating system. Answer : The last byte of the address range is automatically generated with a minimum 00 and maximum FF.
Answer : Dynamically Expanding Fixed Differencing. What Are Pass-through Disks? Answer : A pass-through disk is the term used to identify a physical disk that is not a member of a pool, but is used as a storage source in a virtual disk. You cannot hot-add on an IDE controller of a virtual machine. What Are Vm Snapshots?

Answer : A snapshot preserves the state and data of a virtual machine at a specific point in time. Answer : Deleting snapshots can take a long time In tests the time required to commit the snapshot is not just about the size of the snapshot file, but also about the maximum number of IOPS the disks can deliver where the snapshot and the base disk lie. Even the write rate of the VM during snapshot committing impacts the required time to clean up significantly. Answer : Apply-The current state of the virtual machine and its guest operating system is captured.
