Which of the following is true regarding Group Managed Service Accounts (gMSAs) in Windows?

Which of the following is true regarding Group Managed Service Accounts (gMSAs) in Windows?

• gMSAs are supported on Windows Server 2008 R2 and later versions.
• gMSAs do not have passwords.
• gMSAs are not supported in SQL Server.
• gMSAs can be used to run Scheduled Tasks. 

EXPLANATION

gMSAs can be used to run Scheduled Tasks, but as of Windows Server 2016, their assignment to tasks is still not supported through the Task Scheduler MMC.  Whenever you go to assign one to a task and try to set the task to run without the account being logged on, the console will complain about not receiving a password for the account.
10.196.10.135"The fundamental problem is that you can’t use the Task Scheduler UI. So we’ll use PowerShell cmdlets, instead. (You could also use schtasks.exe with an XML config file, but I’ll let you figure that one out yourself)."
gMSAs are supported on Windows Server 2008 R2 and later versions.MSAs are supported on WS 2008 R2 (but are limited to use on a single computer).  gMSAs require WS 2012 or later.
gMSAs are not supported in SQL Server.
gMSAs (and MSAs) can be used with SQL Server 2012 and later versions.  MSAs can't be used when failover clustering SQL Server.
gMSAs do not have passwords."The password for gMSAs are generated and maintained by the Key Distribution Service (KDS) on Windows Server 2012 DCs..."
"Passwords are very complex and changed automatically as often as desired (by default every 30 days). The passwords are cryptographically random and 240 bytes long."

What is the command to restart IIS services on the command line?

What is the command to restart IIS services on the command line?

• iisrestart
• iisreset
• iisrecycle
• iisrefresh 

EXPLANATION

An IIS server can be restarted without rebooting the entire machine by running the iisreset command on the command line.  There is a button on the IIS management console that can also do this; additionally, you can manually restart the services involved.


Take IISReset as a suite of commands that helps you manage IIS start / stop etc.
Which means you need to specify option (/switch) what you want to do to carry any operation.
Default behavior OR default switch is /restart with iisreset so you do not need to run command twice with /start and /stop.
Hope this clarifies your question. Check this MS DOS help picture you will understand.

In Windows Server, which command line command can you use to determine your logon server?

In Windows Server, which command line command can you use to determine your logon server?

• ipconfig /logonserver
• find /logon_server
• echo %logonserver%
• echo %logon_server% 

EXPLANATION

the DC you use as the logonserver may be one of several in the domain. Your PC will determine the “best” DC to use based on how your AD sites are setup.
If you are in a situation where you need to discover which DC the PC you're using has used to logon you can do this using the echo %logonserver% cmd.

A group of servers that work together to maintain high availability of applications and services is known as a

• Fallover Cluster
• Fallsafe Cluster
• Failsafe Cluster
• Failover Cluster 

EXPLANATION

A failover cluster is a group of servers that work together to maintain high availability of applications and services. If one of the servers, or nodes, fails, another node in the cluster can take over its workload without any downtime (this process is known as failover).

With Microsoft Windows, a split-scope DHCP deployment describes which of the following?

With Microsoft Windows, a split-scope DHCP deployment describes which of the following?

• One server providing a discontinuous address range
• Two servers, each responsible for dedicated scopes
• One server providing multiple scopes and settings 
• Two servers providing addresses from same scope 

EXPLANATION

Split-scope DHCP describes two servers giving away addresses from within the same scope. To avoid conflicts, the scope is cut into segments by adding “exclusion ranges”, so that one DHCP will only hand out addresses the other won’t.

Split-scope DHCP provides redundancy for the network. There is no communication between the DHCPs, so it is not a real failover. Reservations can be created on both servers. Then, in the event that one server fails, the reservation will take effect, even if it is inside the running server's exclusion range.

2012 R2 now offers the more comfortable DHCP-failover clustering, which removes the need for distinct exclusion ranges. Instead, the servers now “talk” to each other and synchronize leases. However, for now no other settings (scope settings, reservations) are synchronized, but there is a PS-script for this as well.
