Topic 3: Northwind Traders
No. of Questions: 10
Overview
Northwind Traders is an IT services and hosting provider.
Northwind Traders has two main data centers in North America. The data centers are located in the same city. The data centers
connect to each other by using high-bandwidth, low-latency WAN links. Each data center connects directly to the Internet.
Northwind Traders also has a remote office in Asia that connects to both of the North American data centers by using a WAN link. The
Asian office has 30 multipurpose servers.
Each North American data center contains two separate network segments. One network segment is used to host the internal servers
of Northwind Traders. The other network segment is used for the hosted customer environments.
Existing Enviornment
Active Directory:
The network contains an Active Directory forest named northwindtraders.com. The forest contains a single domain. All servers run
Windows Server 2012 R2.
Server Enviornment:
The network has the following technologies deployed:
Service Provider Foundation
Windows Azure Pack for Windows Server
System Center 2012 R2 Virtual Machine Manager (VMM)
An Active Directory Rights Management Services (AD RMS) cluster
An Active Directory Certificate Services (AD CS) enterprise certification authority (CA)
All newly deployed servers will include the following components:
Dual 10-GbE Remote Direct Memory Access (RDMA)-capable network adapters
Dual 1-GbE network adapters

128 GB of RAM
Requirments
Business Goals:
Northwind Traders will provide hosting services to two customers named Customer1 andCustomer2.
The network of each customer is configured as shown in the following table.

Planned Changes:
Northwind Traders plans to implement the following changes:
Deploy System Center 2012 R2 Operations Manager.
Deploy Windows Server 2012 R2 iSCSI and SMB-based storage.
Implement Hyper-V Recovery Manager to protect virtual machines.
Deploy a certificate revocation list (CRL) distribution point (CDP) on the internal network.
For Customer 1, install server authentication certificates issued by the CA of Northwind Traders on the virtual machine in the hosting
networks.
General Requirements:
Northwind Traders identifies the following requirements:
Storage traffic must use dedicated adapters.
All storage and network traffic must be load balanced.
The amount of network traffic between the internal network and the hosting network must be minimized.
The publication of CRLs to CDPs must be automatic.

Each customer must use dedicated Hyper-V hosts.
Administrative effort must be minimized, whenever possible.
All servers and networks must be monitored by using Operations Manager.
Anonymous access to internal file shares from the hosting network must be prohibited.
All Hyper-V hosts must use Cluster Shared Volume (CSV) shared storage to host virtual machines.
All Hyper-V storage and network traffic must remain available if single network adapter fails.
The Hyper-V hosts connected to the SMB-based storage must be able to make use of the RDMA technology.
The number of servers and ports in the hosting environment to which the customer has access must be minimized.
Customer1 Requirements:
Northwind Traders identifies the following requirements for Customer1:
Customer1 must use SMB-based storage exclusively.
Customer1 must use App Controller to manage hosted virtual machines.
The virtual machines of Customer1 must be recoverable if a single data center fails.
Customer1 must be able to delegate self-service roles in its hosted environment to its users.
Customer1 must be able to check for the revocation of certificates issued by the CA of Northwind Traders.
The users of Customer1 must be able to obtain use licenses for documents protected by the AD RMS of Northwind Traders.
Certificates issued to the virtual machines of Customer1 that reside on the hosted networks must be renewed automatically.
Customer2 Requirements:
Northwind Traders identifies the following requirements for Customer2:
Customer2 must use iSCSI-based storage exclusively.
All of the virtual machines of Customer2 must be migrated by using a SAN transfer.
None of the metadata from the virtual machines of Customer2 must be stored in Windows Azure.
The network configuration of the Hyper-V hosts for Customer2 must be controlled by using logical switches.
The only VMM network port profiles and classifications allowed by Customer2 must be low-bandwidth, medium-bandwidth, or highbandwidth.
The users at Northwind Traders must be able to obtain use licenses for documents protected by the AD RMS cluster of Customer2.
Customer2 plans to decommission its AD RMS cluster during the next year.

You need to recommend a network configuration for the newly deployed Hyper-V hosts used by Customer1.
On which network adapter should you recommend performing each configuration? To answer, select the appropriate network adapter for each configuration in the
answer area.

Answer:

Explanation:
All newly installed server contains a dual-port 10GbE network adapters with support for Remote Direct Memory Access (RDMA) and a dual-port 1 GbE network
adapter. See the section General requirements states that:
Access the Hyper-V hosts to the storage and network traffic with the virtual machines must be possible even if a single network adapter.
The need to use Hyper-V hosts that are SMB-based storage Remote Direct Memory Access (RDMA) can use technology.
Windows Server 2012 includes the new feature “SMB Direct”, which supports the use of network adapters with function for direct remote memory access (Remote
Direct Memory Access, RDMA). Network adapters with RDMA can at maximum speed to work with very low latency – and the CPU usage at very low. For workloads
such as Hyper-V or Microsoft SQL Server, this means that a remote file server is equivalent to a local store. “SMB Direct” features
Increased throughput: uses the entire throughput of high-speed networks, the network adapter coordinate the transfer large amounts of data at the transfer rate
of the line.
Low latency: provides extremely fast responses to network requirements and consequently aroused the impression that the remote storage of files is just like
saving a block storage directly connected.
Low CPU usage: used in data transmission over the network CPU cycles, thereby maintaining more power reserves for server applications.

“SMB Direct” 2012 will be configured automatically by Windows Server. “SMB Multichannel” and “SMB Direct” When “SMB Multichannel” is the feature for
detecting the RDMA function of network adapters to enable “SMB Direct”.
Without “SMB Multichannel,” used SMB regular TCP / IP for RDMA-capable network adapter (all network adapters provide along with the new RDMA stack a TCP /
IP stack available). With “SMB Multichannel” recognizes SMB whether a network adapter on the RDMA function features.
Subsequently, several RDMA connections for that one session be made (two per port). This enables the use of SMB high throughput, low latency and low CPU
utilization that can offer RDMA-capable network adapters. The feature also provides a fault tolerance, if you use multiple RDMA interfaces.
Important:
You should not be summed up in teams RDMA-capable network adapters if you want to use the RDMA function of the network adapter. In a summary in the
team network adapters do not offer RDMA support.
After at least one RDMA network connection was created that used for the original protocol negotiation TCP / IP connection is no longer used. In the event that
the RDMA network connections fail, the TCP / IP connection remains applicable.
