Microsoft 74-409 Online Questions & Answers

• Question 41:

  A company has a Windows Server 2012 R2 server named NYC-HOST1 that has the Hyper-V role installed. The host server hosts two virtual machines named SALES1 and SALES2. NYC- HOST1 uses storage spaces with tiered storage. The storage spaces contain both solid state disks (SSDs) and 10,000 RPM Serial Attached SCSI (SAS) disks for .vhdx files. Each virtual machine runs on its own .vhdx file.

  You plan to add new virtual machines each month. SALES1 and SALES2 must run at the highest possible performance at all times.

  You need to configure the virtual machines.

  What should you do?

  A. Add additional SSDs to the storage space that is occupied by SALES1 and SALES2.
  B. Replace the 10,000 RPM SAS disks with 15,000 RPM SAS disks.
  C. Move the .vhdx files from the storage spaces to individual SAS hard disks.
  D. Pin the .vhdx files for SALES1 and SALES2 to the fast tier.
  D. Pin the .vhdx files for SALES1 and SALES2 to the fast tier.

• Question 42:

  You have three Windows Server 2012 R2 servers that are set up as a Hyper-V cluster. You use System Center 2012 R2 Virtual Machine Manager to manage the Hyper-V environment. Users report that when a Hyper-V host server becomes

  overloaded, the performance of the virtual machines is unacceptable. You need to analyze workloads and automatically migrate virtual machines from overloaded host servers to host clusters that have available capacity.

  What should you configure?

  A. Performance and Resource Optimization (PRO)
  B. Placement Rules
  C. shared .vhdx file
  D. Dynamic Optimization
  D. Dynamic Optimization

  Ref: http://technet.microsoft.com/en-us/library/gg675109.aspx Dynamic Optimization in VMM During Dynamic Optimization, VMM migrates virtual machines within a host cluster to improve load balancing among hosts and to correct any placement constraint violations for virtual machines.

  Dynamic Optimization can be configured on a host group, to migrate virtual machines within host clusters with a specified frequency and aggressiveness. Aggressiveness determines the amount of load imbalance that is required to initiate a migration during Dynamic Optimization. By default, virtual machines are migrated every 10 minutes with medium aggressiveness. When configuring frequency and aggressiveness for Dynamic Optimization, an administrator should factor in the resource cost of additional migrations against the advantages of balancing load among hosts in a host cluster. By default, a host group inherits Dynamic Optimization settings from its parent host group.

  Dynamic Optimization can be set up for clusters with two or more nodes. If a host group contains stand-alone hosts or host clusters that do not support live migration, Dynamic Optimization is not performed on those hosts. Any hosts that are in maintenance mode also are excluded from Dynamic Optimization. In addition, VMM only migrates highly available virtual machines that use shared storage. If a host cluster contains virtual machines that are not highly available, those virtual machines are not migrated during Dynamic Optimization. On demand Dynamic Optimization also is available for individual host clusters by using the Optimize Hosts action in the VMs and Services workspace. On demand Dynamic Optimization can be performed without configuring Dynamic Optimization on host groups. After Dynamic Optimization is requested for a host cluster, VMM lists the virtual machines that will be migrated for the administrator's approval.

• Question 43:

  An organization has private and public cloud resources. The organization has Windows Server 2012 R2 servers that have the Hyper-V role installed. You have one four-node cluster of Hyper- V host servers. You use System Center 2012 R2.

  The virtual machines that run on the cluster must remain online when you install updates on the Hyper-V host servers.

  You need to install updates on the Hyper-V host servers.

  What should you do?

  A. Configure Windows Server Update Services (WSUS) to provide updates to the Hyper-V host servers in the cluster.
  B. Add all the virtual machines hosted on the cluster to a collection in System Center 2012 R2 Configuration Manager. Deploy updates to the collection.
  C. Use the Cluster-Aware Updating (CAU) wizard.
  D. Configure Windows Update on the Hyper-V host servers to download updates from Microsoft Update.
  C. Use the Cluster-Aware Updating (CAU) wizard.

  Ref: http://technet.microsoft.com/en-us/library/gg675084.aspx

  CAU is an automated feature that enables you to update clustered servers with little or no loss of availability during the update process. During an Updating Run, CAU transparently performs the following tasks:

  ?Puts each node of the cluster into node maintenance mode ?Moves the clustered roles off the node ?Installs the updates and any dependent updates

  ?Performs a restart if necessary

  ?Brings the node out of maintenance mode

  ?Restores the clustered roles on the node

  ?Moves to update the next node

  For many clustered roles (formerly called clustered applications and services) in the cluster, the automatic update process triggers a planned failover, and it can cause a transient service interruption for connected clients. However, in the case

  of continuously available workloads such as Hyper-V with live migration or file server with SMB Transparent Failover, CAU can coordinate cluster updates with no impact to the service availability.

  Note

  The CAU feature is only compatible with Windows Server 2012 R2 and Windows Server 2012 failover clusters and the clustered roles that are supported on those versions.

  Port Mirroring With Port Mirroring, traffic sent to or from a Hyper-V Virtual Switch port is copied and sent to a mirror port. There are a range of applications for port mirroring - an entire ecosystem of network visibility companies exist that have products designed to consume port mirror data for performance management, security analysis, and network diagnostics. With Hyper-V Virtual Switch port mirroring, you can select the switch ports that are monitored as well as the switch port that receives copies of all the traffic.

  The following examples configure port mirroring so that all traffic that is sent and received by both MyVM and MyVM2 is also sent to the VM named MonitorVM.
