1.What is Nano Sever?
Ans. Nano Server is a new installation option in the Windows Server that provides the lowest possible Windows footprint. It is a remotely administered Server operating system optimized for private clouds and data centers. It is like Server core, but significantly smaller. It does not have local logon capabilities, and it supports only 64-bit applications, tools, and agents. It takes up far less disk space, sets up significantly faster, and requires far fewer updates and restarts than a windows servers. Even if it restarts, it restarts significantly quicker.
2. Differences in NANO Server?
Ans. Important differences in Nano Server
Because Nano Server is optimized as a lightweight operating system for running “cloud-native” applications based on containers and micro-services or as an agile and cost-effective datacentre host with a dramatically smaller footprint, there are important differences in Nano Server versus Server Core or Server with Desktop Experience installations:
- Nano Server is “headless;” there is no local logon capability or graphical user interface.
- Only 64-bit applications, tools, and agents are supported.
- Nano Server cannot serve as an Active Directory domain controller.
- Group Policy is not supported. However, you can use Desired State Configuration to apply settings at scale.
- Nano Server cannot be configured to use a proxy server to access the internet.
- NIC Teaming (specifically, load balancing and failover, or LBFO) is not supported. Switch-embedded teaming (SET) is supported instead.
- System Centre Configuration Manager and System Centre Data Protection Manager are not supported.
- Best Practices Analyser (BPA) cmdlets and BPA integration with Server Manager are not supported.
- Nano Server does not support virtual host bus adapters (HBAs).
- Nano Server does not need to be activated with a product key. When functioning as a Hyper-V host, Nano Server does not support Automatic Virtual Machine Activation (AVMA). Virtual machines running on a Nano Server host can be activated using Key Management Service (KMS) with a generic volume license key or using Active Directory-based activation.
- The version of Windows PowerShell provided with Nano Server has important differences. For details, see PowerShell on Nano Server.
Nano Server is supported only on the Current Branch for Business (CBB) model–there is no Long-Term Servicing Branch (LTSB) release for Nano Server at this time. See the following subsection for more information.
3. How many types of back up available and describe them?
Ans. Normal Backup: A normal backup copies all selected files and marks each as having been backed up. With normal backups, you need only the most recent copy of the backup file to restore all the files.
Incremental Backup: An incremental backup backs up only those files created or changed since the last normal or incremental backup. It marks files as having been backed up. If you use a combination of normal and incremental backups, you need the last normal backup set as well as all the incremental backup sets to restore your data.
Differential Backup: A differential backup copies files created or changed since the last normal or incremental backup. It does not mark files as having been backed up. If you are doing normal and differential backups, you must have the last normal and last differential backup sets to restore.
Copy Backup: A copy backup copies all selected files but does not mark each file as having been backed up. Copying is useful to back up files between normal and incremental backups because it does not affect other backup operations.
Daily Backup: A daily backup copies all selected files that have been modified on the day that the daily backup is performed. The backed-up files are not marked as having been backed up.
Full Backup: A Full backup is the starting point for all other backups and contains all the data in the folders and files that are selected to be backed up. Because the full backup stores all files and folders, frequent full backups result in faster and simpler restore operations.
4. What are partitioning tables supported by Windows Server 2016?
Ans. There are two types of partitioning supported by Microsoft Server 2016; they are:
- GPT (GUID Partitioning Table): GPT also allows for a nearly unlimited number of partitions, but Windows allows up to 128 partitions on a GPT drive, and you don’t have to create an extended partition to make them work.
- MBR (Master Boot Recorder): MBR is the information in the first sector of any hard disk or diskette that identifies how and where an operating system is located so that it can be boot (loaded) into the computer’s main storage or random-access memory.
5. What is the size of the Small Memory Dump file?
Ans. 256 kb
6. What is the port number of POP3?
Ans. Port Number for POP3 Incoming is 110.
7. What is the port number of DHCP?
Ans. DHCP Server 67 & DHCP Client 68.
8. Using which syntax of ping command hostname can be determined from IP address?
Ans. Ping -a
9. Which node in the Server Manager Console of a file server Installed on Windows Server 2008 would help to determine the number of duplicate files on a particular volume?
Ans. File Server Resource Manager.
10. How to secure SNMP Traffic?
Ans. By adding an extra filter and creating an IPsec policy you can secure the SNMP traffic.
