Microsoft - 70-740: Installation, Storage, and Compute with Windows Server 2016

Sample Questions

Question: 304
Measured Skill: Implement high availability (30–35%)

You are an administrator for a company. You are building a failover cluster named Cluster1.

You plan to add the following cluster roles to Cluster1:
  • A DHCP Server named DHCP1
  • An iSCSI Target Server named ISCSI1
  • A Scale-Out File Server named SOFS1
Which roles require a Cluster Shared Volumes (CSV) disk?

AISCSI1 only
B SOFS1 and ISCSI1 only
C DHCP1, SOFS1, and ISCSI1
D SOFS1 only

Correct answer: D

Explanation:

Scale-Out File Server requires the use of Clustered Shared Volumes (CSVs).

Cluster Shared Volumes (CSV) enable multiple nodes in a failover cluster to simultaneously have read-write access to the same LUN (disk) that is provisioned as an NTFS volume. (In Windows Server 2012 R2, the disk can be provisioned as NTFS or Resilient File System (ReFS).) With CSV, clustered roles can fail over quickly from one node to another node without requiring a change in drive ownership, or dismounting and remounting a volume. CSV also help simplify the management of a potentially large number of LUNs in a failover cluster.

CSV provide a general-purpose, clustered file system, which is layered above NTFS (or ReFS in Windows Server 2012 R2). CSV applications include:

  • Clustered virtual hard disk (VHD) files for clustered Hyper-V virtual machines

  • Scale-out file shares to store application data for the Scale-Out File Server clustered role. Examples of the application data for this role include Hyper-V virtual machine files and Microsoft SQL Server data. (Be aware that ReFS is not supported for a Scale-Out File Server.)

Question: 305
Measured Skill: Implement storage solutions (10–15%)

You are an administrator for a company. You have a server named Server1.

You need to create a Storage Spaces-based volume that meets the following requirements:
  • Provides the highest resiliency
  • Provides storage tiering
Which storage configuration parameters should you identify?

(To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.)

www.cert2brain.com

AMinimum number of disks: 10
Virtual disk configuration: Mirror layout and fixed provisioning
B Minimum number of disks: 6
Virtual disk configuration: Parity layout and thin provisioning
C Minimum number of disks: 6
Virtual disk configuration: Mirror layout and thin provisioning
D Minimum number of disks: 10
Virtual disk configuration: Mirror layout and thin provisioning
E Minimum number of disks: 12
Virtual disk configuration: Parity layout and thin provisioning
F Minimum number of disks: 12
Virtual disk configuration: Mirror layout and thin provisioning

Correct answer: A

Explanation:

The base for storage tiering is laid at the storage pool level. All types of virtual disks support storage tiering. Storage tiering is only supported by virtual disks with thin provisioning.

Mirroring can tolerate the failure of up to two disks when using three-way mirroring. A virtual disk with three-way mirroring requires at least five disks.

The parity layout provides protection against the failure of two volumes using at least seven volumes.

Note: RAID 5 provides maximum protection against the failure of a single volume, regardless of the number of volumes used.

The fixed deployment type allocates the entire space of the selected volume size when the volume is created, and has the advantage over the thin type of provisioning to avoid overbooking of the physical memory.

Question: 306
Measured Skill: Maintain and monitor server environments (10–15%)

Your network contains an Active Directory domain. The domain contains two servers named Server1 and Server2.

On Server1 and Server2, you use Windows Server Backup to create backups every day at 01:00 and 17:00. You configure Server1 to back up to a network share. You configure Server2 to back up to a locally attached hard disk that is dedicated for backup.

The first backups are created on Monday at 01:00.

How many recovery points will be available for each server on Thursday at 14:00?

(To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.)

www.cert2brain.com

AServer1: 1
Server2: 1
B Server1: 1
Server2: 7
C Server1: 6
Server2: 6
D Server1: 7
Server2: 7
E Server1: 7
Server2: 6
F Server1: 8
Server2: 1

Correct answer: B

Explanation:

If you back up to a network share using Windows Server Backup, only the last backup is retained.

Server2's dedicated backup disk has the following backups on Thursday at 2:00 pm:

  • Monday 01:00
  • Monday 17:00
  • Tuesday 01:00
  • Tuesday 17:00
  • Wednesday 01:00
  • Wednesday 17:00
  • Thursday 01:00


Question: 307
Measured Skill: Implement Hyper-V (20–25%)

You are an administrator for a company. You have the Hyper-V hosts shown in the following table.



Server1 hosts the virtual machines shown in the following table.



Which virtual machine supports Secure Boot, and which virtual machine can be imported onto Server2?

(To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.)

www.cert2brain.com

ASupports Secure Boot: VM1
Can be imported onto Server2: VM1
B Supports Secure Boot: VM1
Can be imported onto Server2: VM2
C Supports Secure Boot: VM2
Can be imported onto Server2: VM3
D Supports Secure Boot: VM2
Can be imported onto Server2: VM2
E Supports Secure Boot: VM3
Can be imported onto Server2: VM3
F Supports Secure Boot: VM3
Can be imported onto Server2: VM1

Correct answer: A

Explanation:

Secure Boot is a feature available with generation 2 virtual machines that helps prevent unauthorized firmware, operating systems, or Unified Extensible Firmware Interface (UEFI) drivers (also known as option ROMs) from running at boot time. Secure Boot is enabled by default. You can use secure boot with generation 2 virtual machines that run Windows or Linux distribution operating systems.

The following table lists the VM configuration versions that are supported on hosts running a long-term servicing version of Windows.

Question: 308
Measured Skill: Implement high availability (30–35%)

You are an administrator for a company. You have a stretch cluster that contains four nodes.

You run Get-ClusterFaultDomain and receive the output shown in the following exhibit.



Node1 and Node2 are in a data center in an Active Directory site named London_Site. Node3 and Node4 are in an Active Directory site named Berlin_Site.

You need to ensure that the active nodes are in London_Site unless both Node1 and Node2 are offline.

How should you complete the command?

(To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.)

www.cert2brain.com

A(Get-Cluster) PreferredSite= "London_Site"
B (Get-ClusterFaultDomain) Name= "Berlin_Site"
C (Set-ClusterQuorum) FaultDomain= "Berlin_Site"
D (Set-ClusterQuorum) PreferredSite= "Berlin"
E (Update-ClusterFunctionalLevel) Location= "London_Site"
F (Update-ClusterFunctionalLevel) FaultDomain= "London"

Correct answer: A

Explanation:

Windows Server 2016, debuts the birth of site-aware clusters. Nodes in stretched clusters can now be grouped based on their physical location (site). Cluster site-awareness enhances key operations during the cluster lifecycle such as failover behavior, placement policies, heartbeating between the nodes and quorum behavior.

If sites are configured ,cluster roles failover to a node within the same site, before failing to a node in a different site

Configuring a Preferred Site for your cluster enhances operation in the following ways: 

Cold Start 
During a cold start VMs are placed in in the preferred site 

Quorum 

  • Dynamic Quorum drops weights from the Disaster Recovery site (DR site i.e. the site which is not designated as the Preferred Site) first to ensure that the Preferred Site survives if all things are equal. In addition, nodes are pruned from the DR site first, during regroup after events such as asymmetric network connectivity failures.

  • During a Quorum Split i.e. the even split of two datacenters with no witness, the Preferred Site is automatically elected to win.

    • The nodes in the DR site drop out of cluster membership

    • This allows the cluster to survive a simultaneous 50% loss of votes

    • Note that the LowerQuorumPriorityNodeID property previously controlling this behavior is deprecated in Windows Server 2016

To configure the Preferred Site for a cluster, launch PowerShell as an Administrator and type: 

(Get-Cluster).PreferredSite = <Site assigned to a set of cluster nodes>
