Explanation:
File Share Witness
The file share witness is used to establish a majority node set. This is done by create a share on a server that gets a little file place into it automatically.
The server hosting the cluster resource (which in the DAG I think is the Primary Activation Manager server) keeps an open file lock on this file.
The other servers see this open file lock and interpret this as meaning another cluster node is online, healthy, and available.
A file share witness is used when the DAG contains an even number of servers within it.
When you initially create the DAG you must specify the server and file location that will act as the file share witness regardless of how many servers are in the DAG (0 to start) to ensure that if you do add an even number of DAG members the FSW will be properly used.
Database Availability Group
A database availability group (DAG) is a set of up to 16 Microsoft Exchange Server 2013 Mailbox servers that provide automatic database-level recovery from a database, server, or network failure. When a Mailbox server is added to a DAG, it works with the other servers in the DAG to provide automatic, database-level recovery from database, server, and network failures.
DAGs use continuous replication and a subset of Windows failover clustering technologies to provide high availability and site resilience.
Mailbox servers in a DAG monitor each other for failures. When a Mailbox server is added to a DAG, it works with the other servers in the DAG to provide automatic, database-level recovery from database failures.
When you create a DAG, it's initially empty, and a directory object is created in Active Directory that represents the DAG. The directory object is used to store relevant information about the DAG, such as server membership information. When you add the first server to a DAG, a failover cluster is automatically created for the DAG. In addition, the infrastructure that monitors the servers for network or server failures is initiated. The failover cluster heartbeat mechanism and cluster database are then used to track and manage information about the DAG that can change quickly, such as database mount status, replication status, and last mounted location.
Witness server and witness directory The witness server is a server outside the DAG that acts as a quorum voter when the DAG contains an even number of members. The witness directory is a directory created and shared on the witness server for use by the system in maintaining a quorum.
Lagged copy of a mailbox database
A Lagged Mailbox Database Copy is a mailbox database copy configured with a replay lag time value greater than 0.
A lagged database copy is one that is not updated by replaying transactions as they become available.
Instead, the transaction logs are kept for a certain period and are then replayed.
The lagged database copy is therefore maintained at a certain remove to the active database and the other non-lagged database copies. If you are planning to have more than two passive database copies of a database, think about a lagged copy also as an additional protection against unpredicted situations Lagged copies aren't considered highly available copies. Instead, they are designed for disaster recovery purposes, to protect against store logical corruption.
The greater the replay lag time set, the longer the database recovery process. Depending on the number of log files that need to replayed during recovery, and the speed at which your hardware can replay them, it may take several hours or more to recover a database.

The above configuration provides a symmetrical design. All four servers have the same four databases all hosted on a single disk per server.
The key is that the number of copies of each database that you have should be equal to the number of database copies per disk.
In the above example, there are four copies of each database: one active copy, two passive copies, and one lagged copy. Because there are four copies of each database, the proper configuration is one that has four copies per volume. In addition, activation preference is configured so that it's balanced across the DAG and across each server.
For example, the active copy will have an activation preference value of 1, the first passive copy will have an activation preference value of 2, the second passive copy will have an activation preference value of 3, and the lagged copy will have an activation preference value of 4.

FSW is the File Share Witness


ASIDE
Windows NLB is not supported across sites.
It is not recommended to use an HLB to load balance across sites.
PICTURE1 OFFERS THE BEST DESIGN IN ORDER TO MEET THE SPECIFIED CRITERIA.
MORE FAULTS WITH THE OTHERS.
PICTURE1 HOWEVER DOES NOT OFFER SITE RESILIENCY.
- Ensure that users can access their mailbox if the WAN link fails.
- Ensure that users can access their mailbox if a single server fails.
- Ensure that users can access their mailbox if a single database fails.
Picture1
The DAG is NOT extended across multiple data centers in a site resilience configuration.
The design offers high availability within each site.
However if a node fails or the wan link fails the respective file share witness for each DAG is still available unlike the other 3 configurations.
Picture2
The DAG is extended across multiple data centers in a site resilience configuration.
No high availability within each site.
If the wan link is unavailable the file share witness for Site2 would be unavailable This is a split brain scenario, both sites believe that they are the rightful owner of the database, and thus would mount their respective DB's. This would cause a divergence in data.
Email could be sent to either database leaving to a difference between the databases on the respective mailbox servers.
Picture3
The DAG is extended across multiple data centers in a site resilience configuration.
FSW on Site2 in the event of a wan failure means that the servers cannot contact a FSW Even number of nodes on the respective site with an inability to contact the FSW.
This is a split brain scenario, both sites believe that they are the rightful owner of the database, and thus would mount their respective DB's. This would cause a divergence in data.
Email could be sent to either database leaving to a difference between the databases on the respective mailbox servers.
A file share witness is used when the DAG contains an even number of servers within it.
A Node Majority quorum model is used for DAGs with an odd number of members.
A Node and File Share Majority quorum is used for DAGs with an even number of members.
The DAG needs to be able to make Quorum.
When 1 node fails in Site1 and the wan link is down,1 out of 2 nodes left is not a majority. Need to be able to connect to the file share witness to obtain a majority.
Picture4
1 DAG across both sites provides site resiliency but FSW on Site1 in the event of a wan failure means that the servers cannot contact a FSW A file share witness is used when the DAG contains an even number of servers within it.
Even number of nodes on the respective site with an inability to contact the FSW.
This is a split brain scenario, both sites believe that they are the rightful owner of the database, and thus would mount their respective DB's. This would cause a divergence in data.
Email could be sent to either database leaving to a difference between the databases on the respective mailbox servers.
A file share witness is used when the DAG contains an even number of servers within it.

A Node and File Share Majority quorum is used for DAGs with an even number of members.

NEW QUESTION: 2
Billy is the project manager of the PQW Project and she has an assigned project budget of $655,000.
Currently she is 80 percent complete with the project though she was scheduled to be 90 percent done by this date. She has spent $490,000 to date. What should Billy report as her cost performance index (CPI)for this project?
A. .07
B. $34,000
C. 1.07
D. .89
Answer: C
Explanation:
Explanation/Reference:
Explanation:
Cost performance index (CPI) is used to calculate performance efficiencies. It is used in trend analysis to predict future performance. CPI is the ratio of earned value to actual cost. The CPI is calculated based on the following formula: CPI = Earned Value (EV) / Actual Cost (AC) If the CPI value is greater than 1, it indicates better than expected performance, whereas if the value is less than 1, it shows poor performance. The CPI value of 1 indicates that the project is right on target. In this instance the earned value is $524,000 and the actual costs are $490,000. In this project Billy has spent less than what the work is worth - a good thing. This could be because of a cost savings, such as travel or shipping, or because a risk event didn't come into play. This causes the positive CPI - something which does not happen very often.
Incorrect Answers:
A: .07 is an incorrect calculation for the cost performance index for the project.
C: $34,000 is the cost variance of the project.
D: .89 represents the schedule performance index.

NEW QUESTION: 3
HyperMetro program, the following description of the arbitration mode, which is correct? (Multiple choice)
A. The arbitration mode is a static priority and without heartbeat link is needed because no arbitration server needs to be configured in this mode.
B. The arbitration mode is static priority. When the priority site array fails, the non-priority site can't automatically take over the dual active service and the dual active service stops. The non-priority service needs to be manually forcibly started.
C. The arbitration mode is static priority. When the priority site array is powered off and maintained, the non-priority site array immediately takes over all the active and inactive services and the service will not be interrupted.
D. If there are multiple active-active groups in a dual-active domain, according to different business consistency group configure different dual live arbitration mode.
Answer: B,C
