Testlet 1
Topic 2. Photo Processing
Background
General Background
You are a SharePoint administrator for an online photo-processing company named Contoso, Ltd. Contoso’s primary customers are professional photographers.
The Contoso SharePoint 2013 environment includes the sites described in the following table.

The intranet site includes a document library for each employee in which the employee stores photos.
Technical Background
The SharePoint environment contains five front-end web servers that use Windows Network Load Balancing (NLB) with NLB affinity set to None. The company
maintains all processed photos in the SharePoint content database. The content database uses RAID 5 storage. Photo files that are more than one year old are
rarely viewed. Employees actively use the default self-service site creation feature.
The network infrastructure contains an Active Directory Domain Services (AD DS) environment. All servers run Windows Server 2008 R2. The internal AD DS
domain is named contoso.com. Active Directory Federation Services (AD FS) is deployed in the LAN. Two AD FS proxy servers are deployed in the perimeter
network. Users log on to client computers by using the syntax username@contoso.com.
Contoso has a lab environment that includes a dedicated AD DS environment and SharePoint 2013. The main lab SharePoint site is located at
lab.intranet.contoso.com. A test site for a project named Project2 exists under lab.intranet.contoso.com/corp. The default self-service site creation feature is
enabled for the test site.
Contoso has a development team that maintains the public website, maintains the intranet site, and creates SharePoint apps. The development team recently
created a SharePoint-hosted app named App1 that converts .tif files to .png files.
Future Development
Contoso is forming a new corporation named Proseware, Inc. that will sell SharePoint apps. The company has acquired the proseware.com domain name.
Contoso is preparing to federate with Microsoft Office 365 and will use the proseware.com domain for Office 365 services.
Technical Requirements
You must meet the following technical requirements:

App1 must have access to each employee’s photo document library.
App1 must use Windows Authentication.
Each front-end web server must use a single IP address for all SharePoint sites and apps on that server.
All SharePoint sites and apps must listen on port 9000.
Office 365 must use single sign-on (SSO).
The company has established the following new monitoring requirements for the production SharePoint environment:
Monitor whether a large number of documents are checked out.
Monitor whether a large number of unpublished items are being requested.
The company has established the following new monitoring requirements for Project2:
Monitor changes to a value in a specific registry key.
Monitor the SharePoint cache hit ratios.
Perform monitoring only from 9:00 A.M. to 3:00 P.M. daily.
Existing Problems
Multiple authentications often occur when users log on to and navigate in SharePoint. Users have reported some small delays accessing data.
The content database is currently stored on Serial Attached SCSI (SAS) disk drives and is growing at a rapid pace. The following related issues currently exist:
SharePoint is not performing as well as it was when the content database was smaller.
Storage costs to house the photo files are too expensive.
Scanned contracts are stored in binary large object (BLOB) cache storage. The BLOB cache is routinely filling up. End users are reporting poor performance when
viewing scanned contracts.

DRAG DROP
You are troubleshooting the problems with viewing scanned contracts.
You need to select the appropriate Performance Monitor counters to use.
Which performance counters should you use? (To answer, drag the appropriate counters to the correct location or locations in the answer area. Each counter may
be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Answer:

Explanation:
Scenario:
Scanned contracts are stored in binary large object (BLOB) cache storage. The BLOB cache is routinely filling up.
End users are reporting poor performance when viewing scanned contracts.
The Blob Cache fill ratio performance counter threshold has been exceeded. Cause: The configured size for the disk-based cache is smaller than the total size of
frequently accessed files for the Web application.
Total Number of cache Compactions:
If this number is continually or frequently high, the cache size is too small for the data being requested. To improve performance, increase the size of the cache.
