Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)
A. Run the Update-CsUserDatabase cmdlet.
B. From the Topology Builder, create a new Enterprise Edition Front End pool and a new SQL Server database, SQL Server database mirroring, and a witness.
C. On the SQL Server servers, install Failover Clustering.
D. On the Front End Servers, install Failover Clustering.
E. From the Topology Builder, publish the topology and install the databases.
F. Run the Invoke-CsDatabaseFailover cmdlet.
Answer: B,E
Explanation:
http://technet.microsoft.com/en-us/library/jj204992.aspx DEPLOYING SQL MIRRORING FOR BACK END SERVER HIGH AVAILABILITY
To be able to deploy SQL mirroring, your servers must run a minimum of SQL Server 2008
R2. This version must run on all the involved servers: the primary, mirror, and the witness.
For details, see http://go.microsoft.com/fwlink/p/?linkid=3052&kbid=2083921.
In general, setting up SQL mirroring between the two Back End Servers with a witness
requires the following:
The primary server's version of SQL Server must support SQL mirroring.
The primary, mirror, and the witness (if deployed) must have the same version of SQL
Server.
The primary and the mirror must have the same edition of SQL Server. The witness may
have a different edition.
For SQL best practices in terms of what SQL versions are supported for a Witness role,
see "Database Mirroring Witness" in the MSDN Library at
http://go.microsoft.com/fwlink/p/?LinkId=247345.
You use Topology Builder to deploy SQL mirroring. You select an option in Topology
Builder to mirror the databases, and Topology Builder sets up the mirroring (including
setting up a witness, if you want) when you publish the topology. Note that you set up or
remove the witness at the same time you set up or remove the mirror. There is no separate
command to deploy or remove only a witness.
To configure server mirroring, you must first set up SQL database permissions correctly.
For details, see "Set Up Login Accounts for Database Mirroring or AlwaysOn Availability
Groups (SQL Server)" at http://go.microsoft.com/fwlink/p/?LinkId=268454.
With SQL mirroring, database recovery mode is always set to Full, which means you must closely monitor transaction log size and back up transaction logs on a regular basis to avoid running out of disk space on the Back End Servers. The frequency of transaction log backups depends on the log growth rate, which in turn depends on database transactions incurred by user activities on the Front End pool. We recommend that you determine how much transaction log growth is expected for your Lync deployment workload so that you can do the planning accordingly. The following articles provide additional information on SQL backup and log management: Database recovery models: "Recovery Models (SQL Server)" at http://go.microsoft.com/fwlink/p/?LinkId=268446 Backup overview: "Backup Overview (SQL Server)" at http://go.microsoft.com/fwlink/p/?LinkId=268449 Backup transaction log: "Backup a Transaction Log (SQL Server)" at http://go.microsoft.com/fwlink/p/?LinkId=268452 With SQL mirroring, you can either configure the topology for mirroring when you create the pools, or after the pools are already created.
IMPORTANT:
Using Topology Builder or cmdlets to set up and remove SQL mirroring is supported only
when the primary, mirror, and witness (if desired) servers all belong to the same domain. If
you want to set up SQL mirroring among servers in different domains, see your SQL Server
documentation.
TO CONFIGURE SQL MIRRORING WHILE CREATING A POOL IN TOPOLOGY
BUILDER
On the Define the SQL Store page, click New next to the SQL store box.
On the Define new SQL Store page, specify the primary store, select This SQL instance
is in mirroring relation, specify the SQL mirroring port number (the default is 5022), and
then click OK.
Back on the Define the SQL store page, select Enable SQL Store mirroring.
In the Define new SQL Store page, specify the SQL store to be used as the mirror. Select
This SQL instance is in mirroring relation, specify the port number (the default is 5022),
and then click OK.
If you want a witness for this mirror, do the following:
Select Use SQL mirroring witness to enable automatic failover.
In the Define the SQL Store page, select Use SQL mirroring witness to enable
automatic failover, and specify the SQL store to be used as the witness.
Specify the port number (the default is 7022) and click OK.
After you are done defining your Front End pool and all other roles in your topology, use
Topology Builder to publish the topology. When the topology is published, if the Front End
pool that hosts Central Management store has SQL mirroring enabled, you will see an
option to create both primary and mirror SQL store databases.Click Settings, and type the
path to use as the file share for the mirroring backup.Click OK and then Next to create the
databases and publish the topology. The mirroring and the witness (if specified) will be
deployed.
You can use Topology Builder to edit the properties of an already existing pool to enable
SQL mirroring.
TO ADD SQL MIRRORING TO AN EXISTING FRONT END POOL IN TOPOLOGY
BUILDER
In Topology Builder, right-click the pool and then click Edit Properties.
Select Enable SQL Store Mirroring, and then click New next to Mirroring SQL Store.
Specify the SQL store that you want to use as the mirror.
Select This SQL instance is in mirroring relation, specify the SQL mirroring port number
the default port is 5022), and then click OK.
If you want to configure a witness, select Use SQL mirroring witness to enable
automatic failover, and click New.
Specify the SQL store that you want to use as the witness.
Select This SQL instance is in mirroring relation, specify the SQL mirroring port number
(the default port is 7022), and then click OK.
Click OK.
Publish the topology. When you do so, you will be prompted to install the database.
You must then install the database before going on to the next procedure.
You should keep the following in mind when setting up SQL mirroring:
If a mirroring endpoint already exists, it will be reused using the ports defined there, and will
ignore the ones you specify in the topology.
Any port already allocated for other applications on the same server, including those for
other SQL instances, should not be used for the installed SQL instances at hand. This
implies that if you have more than one SQL instance installed on the same server, they
must not use the same port for mirroring. For details, see the following articles:
"Specify a Server Network Address (Database Mirroring)" in the MSDN Library at
http://go.microsoft.com/fwlink/p/?LinkId=247346
"The Database Mirroring Endpoint (SQL Server)" at
http://go.microsoft.com/fwlink/p/?LinkId=247347
USING LYNC SERVER MANAGEMENT SHELL CMDLETS TO SET UP SQL MIRRORING
The easiest way to set up mirroring is by using Topology Builder, but you can also do so
using cmdlets.
Open a Lync Server Management Shell window and run the following cmdlet:
Install-CsMirrorDatabase [-ConfiguredDatabases] [-ForInstance] [-ForDefaultInstance] [-
DatabaseType <Application | Archiving | CentralMgmt | Monitoring | User | BIStaging |
PersistentChat | PersistentChatCompliance >] -FileShare <fileshare> -SqlServerFqdn
<primarySqlserverFqdn> [-SqlInstanceName] [-DatabasePathMap] [-ExcludeDatabaseList]
[-DropExistingDatabasesOnMirror] -Verbose
For example:
Install-CsMirrorDatabase -ConfiguredDatabases -FileShare \\PRIMARYBE\csdatabackup -
SqlServerFqdn primaryBE.contoso.com -DropExistingDatabasesOnMirror -Verbose
You will see the following:

The cmdlet uses this provider to find the account information for SQL Server services running on all primary, mirror and witness servers. Verify that the account running this cmdlet has permission to create the folders for the data and log files for all the mirror servers. Note that the user account that the SQL instance uses to run must have read/write permission to the file share. If the file share is on a different server, and the SQL instance runs a local system account, you must grant file share permissions to the server that hosts the SQL instance. Type A and press ENTER.The mirroring will be configured.
Install-CsMirrorDatabase installs the mirror and configures mirroring for all the databases that are present on the primary SQL store. If you want to configure mirroring for only specific databases, you can use the -DatabaseType option, or if you want to configure mirroring for all databases except for a few, you can use the -ExcludeDatabaseList option, along with a comma-separated list of database names to exclude. For example, if you add the following option to Install-CsMirrorDatabase, all databases except rtcab and rtcxds will be mirrored. -ExcludeDatabaseList rtcab,rtcxds For example, if you add the following option to Install-CsMirrorDatabase, only the rtcab, rtcshared, and rtcxds databases will be mirrored. -DatabaseType User
REMOVING OR CHANGING SQL MIRRORING
To remove the SQL mirroring of a pool in Topology Builder, you must first use a cmdlet to
remove the mirror in SQL Server. You can then use Topology Builder to remove the mirror
from the topology. To remove the mirror in SQL Server, use the following cmdlet:
Uninstall-CsMirrorDatabase -SqlServerFqdn <SQLServer FQDN> [-SqlInstanceName
<SQLServer instance name>] -DatabaseType <Application | Archiving | CentralMgmt |
Monitoring | User | BIStaging | PersistentChat | PersistentChatCompliance> [-
DropExistingDatabasesOnMirror] [-Verbose]
For example, to remove mirroring and drop the databases for the User databases, type the
following:
Uninstall-CsMirrorDatabase -SqlServerFqdn primaryBE.contoso.com -SqlInstanceName rtc
-Verbose -DatabaseType User -DropExistingDatabasesOnMirror
The -DropExistingDatabasesOnMirror option causes the affected databases to be deleted
from the mirror.
Then, to remove the mirror from the topology, do the following:
In Topology Builder, right-click the pool and click Edit Properties.
Uncheck Enable SQL Store Mirroring and click OK.
Publish the topology.
IMPORTANT:
Whenever you make a change to a Back End Database mirroring relationship, you must
restart all the Front End Servers in the pool. For a change in mirroring, (such as changing
the location of a mirror), you must use Topology Builder to perform these three steps:
Remove mirroring from the old mirror server.
Add mirroring to the new mirror server.
Publish the topology.
REMOVING A MIRRORING WITNESS
Use this procedure if you need to remove the witness from a Back End Server mirroring
configuration.
In Topology Builder, right-click the pool and click Edit Properties.
Uncheck Use SQL Server mirroring witness to enable automatic failover and click OK.
Publish the topology.After publishing the topology, Topology Builder you will see a
message that includes the following
Run the Uninstall-CsMirrorDatabase cmdlet to remove databases that are paired with
following primary databases.
However, do not follow that step, and do not type Uninstall-CsMirrorDatabase as that would uninstall the entire mirroring configuration. To remove just the witness from the SQL Server configuration, follow the instructions in "Remove the Witness from a Database Mirroring Session (SQL Server)" at http://go.microsoft.com/fwlink/p/?LinkId=268456.

NEW QUESTION: 3
あなたは、モバイルスリープトラッキングアプリケーションを運営する会社の新しいITアーキテクトです。
夜間に有効にすると、モバイルアプリは収集された1キロバイトのデータポイントを5分ごとにバックエンドに送信します。
バックエンドはユーザーの認証とデータポイントのAmazon DynamoDBテーブルへの書き込みを処理します。
毎朝、テーブルをスキャンして、昨夜のデータをユーザーごとに抽出および集計し、結果をAmazon S3に保存します。ユーザーは、Amazon SNSモバイルプッシュ通知を介して、新しいデータが利用可能であることを通知され、モバイルアプリによって解析および視覚化されます。現在、北米を拠点とするユーザーが約10万人います。
バックエンドシステムのアーキテクチャを最適化して、コストを削減することが求められています。
あなたは何をお勧めします？ 2つの答えを選んでください
A. Amazon DynamoDBテーブルからの読み取りをキャッシュし、プロビジョニングされた読み取りスループットを削減するAmazon Elasticacheを導入します。
B. Amazon S3に保存されたJSONファイルの代わりに、モバイルアプリがAmazon DynamoDBに直接アクセスするようにします。
C. 毎日新しいAmazon DynamoDBテーブルを作成し、データがAmazon S3にある前の日のテーブルを削除します。
D. Amazon SQSキューを導入して、Amazon DynamoDBテーブルへの書き込みをバッファリングし、プロビジョニングされた書き込みスループットを削減します。
E. データをAmazon Redshiftクラスターに直接書き込み、Amazon DynamoDBとAmazon S3の両方を置き換えます。
Answer: C,D
Explanation:
C - reduced provisioned write capacity to the table, SQS will send regular inputs and absorb sudden higher load E - dropping old no longer needed data will save cost.
D is wrong because read is only performed when exporting data to s3, then the backend read all from s3 so reducing provisioned read throughput on the DynamoDB table is useless.
