Windows Server Support Interview Questions and Answers (L1)

IIS

• Fault-tolerant process architecture----- The IIS 6.0 fault-tolerant process architecture isolates Web sites and applications into self-contained units called application pools
• Health Monitoring---- IIS 6.0 periodically checks the status of an application pool with automatic restart on failure of the Web sites and applications within that application pool, increasing application availability. IIS 6.0 protects the server, and other applications, by automatically disabling Web sites and applications that fail too often within a short amount of time
• Automatic Process Recycling--- IIS 6.0 automatically stops and restarts faulty Web sites and applications based on a flexible set of criteria, including CPU utilization and memory consumption, while queuing requests
• Rapid-fail Protection---- If an application fails too often within a short amount of time, IIS 6.0 will automatically disable it and return a "503 Service Unavailable" error message to any new or queued requests to the application

Difference between NT & 2000

• NT SAM database is a flat database. Where as in windows 2000 active directory database is a hierarchical database.
• In windows NT only PDC is having writable copy of SAM database but the BDC is only read only database. In case of Windows 2000 both DC and ADC is having write copy of the database
• Windows NT will not support FAT32 file system. Windows 2000 supports FAT32
• Default authentication protocol in NT is NTLM (NT LAN manager). In windows 2000 default authentication protocol is Kerberos V5.
• Windows 2000 depends and Integrated with DNS. NT user Netbios names
• Active Directory can be backed up easily with System state data

Difference between 2000 & 2003

• Application Server mode is introduced in windows 2003
• Possible to configure stub zones in windows 2003 DNS
• Volume shadow copy services is introduced
• Windows 2003 gives an option to replicate DNS data b/w all DNS servers in forest or All DNS servers in the domain.

Difference between PDC & BDC
PDC contains a write copy of SAM database where as BDC contains read only copy of SAM database. It is not possible to reset a password or create objects without PDC in Windows NT.

Difference between DC & ADC
There is no difference between in DC and ADC both contains write copy of AD. Both can also handles FSMO roles (If transfers from DC to ADC). It is just for identification. Functionality wise there is no difference.

What is DNS & WINS?
DNS is a Domain Naming System, which resolves Host names to IP addresses. It uses fully qualified domain names. DNS is a Internet standard used to resolve host names.
WINS is a Windows Internet Name Service, which resolves Netbios names to IP Address. This is proprietary for Windows

Types of DNS Servers

Primary DNS
Secondary DNS
Active Directory Integrated DNS
Forwarder
Caching only DNS

If DHCP is not available what happens to the client
Client will not get IP and it cannot be participated in network. If client already got the IP and having lease duration it use the IP till the lease duration expires.

What are the different types of trust relationships?
Implicit Trusts
Explicit Trusts—NT to Win2k or Forest to Forest

What is the process of DHCP for getting the IP address to the client?
There is a four way negotiation process b/w client and serverDHCP Discover (Initiated by client)

DHCP Offer (Initiated by server)
DHCP Select (Initiated by client)
DHCP Acknowledgement (Initiated by Server)
DHCP Negative Acknowledgement (Initiated by server if any issues after DHCP offer)

Difference between FAT, NTFS & NTFSVersion5
NTFS Version 5 features
Encryption is possible
We can enable Disk Quotas
File compression is possible
Sparse files
Indexing Service
NTFS change journal
In FAT file system we can apply only share level security. File level protection is not possible. In NTFS we can apply both share level as well as file level security
NTFS supports large partition sizes than FAT file systems
NTFS supports long file names than FAT file systems

What are the port numbers for FTP, Telnet, HTTP, DNS?
FTP-21, Telnet – 23, HTTP-80, DNS-53, Kerberos-88, LDAP-389

What are the different types of profiles in 2000?

Local Profiles
Roaming profiles
Mandatory Profiles

What is the database files used for Active Directory?
The key AD database files—edb.log, ntds.dit, res1.log, res2.log, and edb.chk—all of which reside in \%systemroot%\ntds on a domain controller (DC) by default. During AD installation, Dcpromo lets you specify alternative locations for these log files and database files
NTDS.DIT

What is the location of AD DATABASE?
%System root%/NTDS/NTDS>DIT

What is the authentication protocol used in NT
NTLM (NT LAN Manager)

What is subnetting and supernetting
Subnetting is the process of borrowing bits from the host portion of an address to provide bits for identifying additional sub-networks
Supernetting merges several smaller blocks of IP addresses (networks) that are continuous into one larger block of addresses. Borrowing network bits to combine several smaller networks into one larger network does supernetting

What is the use of terminal services?
Terminal services can be used as Remote Administration mode to administer remotely as well as Application Server Mode to run the application in one server and users can login to that server to user that application.

What is the protocol used for terminal services?
RDP

What is the port number for RDP?
3389
