What is the difference between a Stop and a Drainstop command in NLB on Windows Server 2016?

• The 'Drainstop' command is used to restart the NLB service, while 'Stop' is for shutting it down.

• The 'Stop' command immediately stops the NLB service, while 'Drainstop' allows existing connections to complete before stopping.

• Both commands perform the same function with no difference in behavior.

• The 'Stop' command allows existing connections to complete, while 'Drainstop' immediately stops the NLB service.

Why do you use both port rules and firewall rules when securing NLB?

• Port rules are only necessary for internal traffic.
• Firewall rules alone provide sufficient security for NLB.
• Both port rules and firewall rules are used to ensure comprehensive security for the NLB by controlling access at different levels.
• Using both rules complicates the security setup unnecessarily.

Why should you use the principle of least privilege when assigning permission to NLB servers?

• It simplifies the management of permissions for all users.

• It allows NLB servers to access all resources freely.

• Using the principle of least privilege helps enhance security by restricting permissions to only what is necessary for NLB servers.

• It ensures that NLB servers can perform any task without restrictions.

What is the purpose of using affinity settings in NLB on Windows Server 2016?

• Affinity settings are used to balance the load equally among all servers.

• They ensure that a client is always directed to the same server for a session.

• Affinity settings are used to increase the speed of the network.

• They are used to restrict access to certain servers.

How does NLB handle server failure in a cluster?

• NLB automatically redirects traffic to the remaining servers in the cluster.

• NLB shuts down the entire cluster until the failed server is restored.

• NLB requires manual intervention to redirect traffic after a server failure.

• NLB does not handle server failures; it only balances the load.

What is the role of a host priority in an NLB cluster?

• Host priority determines the order in which servers are added to the cluster.

• It is used to assign more resources to higher priority hosts.

• Host priority is used to determine which server handles traffic if the primary server fails.

• It is used to set the maximum number of connections a server can handle.

What is DNS Round Robin?

• A technique for securing DNS records against attacks.
• A method for caching DNS queries to improve speed.
• A process for synchronizing DNS records across multiple domains.
• DNS Round Robin is a method of load balancing that distributes requests across multiple servers by rotating IP addresses associated with a single domain.

What is the primary benefit of using Network Load Balancing (NLB) in a server environment?

• It increases the speed of individual server processing.

• NLB provides redundancy and improves availability by distributing traffic across multiple servers.

• It reduces the need for server maintenance.

• NLB allows for unlimited server connections.

How does NLB ensure that a specific server in the cluster handles a particular type of traffic?

• By using port rules to direct specific traffic types to designated servers.

• By assigning more resources to the server.

• By increasing the server's processing power.

• By manually configuring each server for specific traffic.

What happens when a new server is added to an existing NLB cluster?

• The new server immediately takes over all traffic.

• The cluster must be restarted to recognize the new server.

• NLB automatically starts distributing traffic to the new server based on the load balancing rules.

• The new server remains inactive until manually configured.
