You are the network administrator for Corpnet.com. You have created a Network Load Balancing cluster to provide high availability for the intranet website. You have three web servers, Web1.corpnet.com, Web2.corpnet.com, and Web3.corpnet.com. You have preformed the following configuration tasks: Each server has one network card installed. Each server has its own disk storage. Each server has the same data. Each server has a static IP address. Each server has the IIS role installed. Each server has the NLB feature installed. Each server has been added to the cluster. The cluster has been assigned its own IP address. When you test access to www.corpnet.com, you get a message that the site can't be reached. Which step still needs to be done?

Create an A record in DNS that points www.corpnet.com to the cluster's IP address.

You are the server administrator for the eastsim.com domain. You have an application server named Srv5 that is used by members of the Sales team. The server runs three applications: App1, App2, and App3. Each application uses a different TCP/IP port. Because of recent growth, this server is becoming unable to process all incoming requests in a timely manner. You decide to use Network Load Balancing (NLB) as your solution. You add a second server named Srv10. Your NLB should meet the following requirements: Requests for App1 and App2 should be evenly distributed between Srv5 and Srv10. Because App3 is not running on Srv10, all requests for that application should be sent to Srv5. Requests should never be directed to Srv10. You need to configure a solution to meet the requirements. What should you do?

For App3, configure a port rule with the filtering mode set to Multiple host. Configure Srv5 with a weight of 30 and Srv10 with a weight of 0.

You are the network administrator for westsim.com. The network consists of a single Active Directory domain. The network contains three Windows servers named FS1, FS2, and FS3. These servers are used for storing files in shared folders. You want to implement failover clustering to make these servers highly available for your users, so you have installed the Failover Clustering feature on each server and have created a cluster with FS1, FS2, and FS3 as the cluster nodes.You are using Storage Spaces Direct (SSD) to set up the shared storage for the cluster, so you install new SATA hard drives in each server and leave them blank, offline, and uninitialized. You open a PowerShell session to begin the SSD implementation. From the drop-down list, select the command you would enter to identify all storage devices that can be added to an SSD pool.

You are the server administrator for the eastsim.com domain. You have an application server named Srv12 that runs a stateless Web application using IIS. Because of recent growth, this server is becoming unable to process all incoming requests in a timely manner. You would like to add a second server to run the application. Your solution should meet the following requirements: Client requests should be divided evenly between the two servers. If one server goes down, all requests should go to the other server. All application data will be stored on internal parallel SCSI drives on each server. You install the application on the second server. You now need to configure a solution to meet the requirements. What should you do?

Configure both servers in a Network Load Balancing (NLB) cluster.

You are the server administrator for the eastsim.com domain. You have an intranet site for your company using IIS and running on Srv5. You are concerned that this server is a single point of failure--if the server goes down, the intranet site will be unavailable. You would like to add a second server to provide redundancy. Your solution should meet the following requirements: All client requests should be directed to Srv5 if it is available. If Srv5 goes down, all requests should be directed to the new server. Both servers should have a separate copy of the Web site data. Web site content will be managed separately on each server. You install the Web site on a second server named Srv10 and copy the Web site content to the server. You now need to configure a solution to meet the requirements. What should you do? (Select two. Each choice is a required part of the solution.)

Configure both servers with a static IP address. Configure both servers in a Network Load Balancing (NLB) cluster. Configure a port rule with the filtering mode set to Single host. Configure Srv5 with a handling priority of 1 and Srv10 with a handling priority of 2.

Members of the accounting department use a custom application for entering payroll and tracking accounts receivable and accounts payable. The application runs on an application server and is cluster-aware. You would like to use Failover clustering to provide redundancy, fault tolerance, and load balancing for the application. Your solution should meet the following requirements: All cluster nodes should be active and respond to client requests. When a cluster node fails, requests should be redistributed between the remaining cluster members. The cluster should continue to operate as long as there are more than half of the cluster members still available. You install Failover Clustering on five servers. Following Microsoft's recommendations, how should you configure the cluster? (Select two. Each choice is a required part of the solution.)

Configure the application as a multiple-instance application. Use node majority for the quorum mode.

You are the server administrator for the eastsim.com domain. You have an intranet site for your company using IIS and running on Srv5. Because of recent growth, this server is becoming unable to process all incoming requests in a timely manner. You decide to use Network Load Balancing (NLB) as your solution. You add a second server named Srv10. Both Srv5 and Srv10 have similar hardware, with a single network adapter. Your NLB should meet the following requirements: New client requests should be directed to either of the two servers. Because of differences in hardware between the two servers, two-thirds of the client requests should be directed to Srv5, with the remaining going to the new server. Both Srv5 and Srv10 must be able to support peer-to-peer communications. You need to configure a solution to meet the requirements. What should you do? (Select two. Each choice is a required part of the solution.)

Configure the cluster to operate in multicast mode. Configure a port rule with the filtering mode set to Multiple host. Configure Srv5 with a weight of 60 and Srv10 with a weight of 30.

You are the network administrator for Corpnet.com. You have six Windows servers that are members of a Failover Cluster named Cluster1. This cluster is a stretch cluster because three nodes are grouped at the main office site, while the other three nodes are grouped at the branch office site. The main office is located on the east coast. while the branch office is located on the west coast. The WAN link between the main office and the branch office has occasional issues with latency, especially during normal business hours. What measures can you take to make sure cluster performance is optimized for these conditions? (select two)

Increase the CrossSubnetThreshold value. Configure asynchronous replication between the main office site and the branch office site.

You are the network administrator for westsim.com. The network consists of a single Active Directory domain. The network contains two Windows servers named HV1 and HV2 that have the Hyper-V role installed. If HV1 fails, you need the virtual machines hosted by HV1 to be migrated to HV2, and you need them to remain available during the migration.What should you do?

Install the Failover Cluster feature on HV1 and create a failover cluster with HV2. Then enable Live Migration.

You are the network administrator for westsim.com. The network consists of a single Active Directory domain. The network contains two servers named FS11 and FS12. Both servers are running Windows Server 2016 Datacenter edition.You have implemented Storage Replica as a disaster recovery solution with FS11 and FS12 as replication partners. When a user makes changes to a file that is stored in a shared folder on FS11 and then saves those changes, the following process takes place:• FS11 writes the changes to its data disk but does not acknowledge the write operation to the user's application. • FS11 replicates the write operation to FS12.• FS12 writes the change to its data disk and acknowledge the write operation back to FS11.• FS11 sends an acknowledgement to the user's application, letting it know the write operation was successful. Which replication type is being used between FS11 and FS12?

Synchronous

You are the network administrator for Corpnet.com. You have created a Network Load Balancing cluster to provide high availability for the intranet website. The NLB luster consists of three web servers; Web1, Web2 and Web3. Each web server has one network card installed. After configuring the NLB cluster, you determine that the web servers in the cluster are unable to communicate with each other. You must reconfigure the cluster to allow communication between the cluster members.

What should you do? Change the cluster operation mode to Multicast

You are the server administrator for the eastsim.com domain. You have implemented a Network Load Balancing (NLB) cluster for several application servers. Client computers use several proxy servers to connect to the NLB cluster. You would like client connections to be directed to a cluster node based on the Class C subnet address. What should you do?

Configure a port rule with the filtering mode set to Multiple host. Configure Network for the client affinity.

Your company is responsible for processing payroll for other businesses. Because the pay days for many businesses are the same, your servers experience heavy loads during some days, with light loads on other days. Payroll processing is done by a custom application running on an application server. To handle the load, you configure Failover Clustering on a cluster of six servers. You want the cluster to keep operating even in the event of a failure of up to three of the nodes. If more than three nodes fail, the cluster should stop. What should you do?

Configure a witness disk. Use node and disk majority for the quorum mode.

You are the server administrator for the eastsim.com domain. Srv5 is an application server that runs an application used by the Sales team. You are concerned that this server is a single point of failure--if the server goes down, the application will be unavailable. You would like to add a second server to provide redundancy. Your solution should meet the following requirements: All client requests should be directed to Srv5 if it is available. If Srv5 goes down, all requests should be directed to the new server. Both servers should use the same set of data files. You want to configure Srv10 to provide redundancy for Srv5. Both Srv5 and Srv10 are configured to use DHCP for IP addressing information. You need to configure a solution to meet the requirements. What should you do?

You are the network administrator for Corpnet.com. You have two Windows Server 2012 R2 servers that are members of a Failover Cluster named Cluster1. One node is located in the main office and the other node is located in a branch office. The sites communicate using IPSec in tunnel mode. After changing ISPs, you discover that the rate of failover increases. You suspect this may be due to latency on the new WAN link. You need to ensure that slow connectivity between the sites does not cause failover. What should you do?

Increase the CrossSubnetThreshold on Cluster1.

You need to failover a virtual machine running on a Windows Server 2012 R2 hypervisor host using the following parameters: The latest changes made to the primary virtual machine must be replicated to its replica virtual machine.
