• Domain, Site, OU, Local
• OU, Domain, Site, Local
• Local, Site, Domain, OU
• Site, OU, Domain, Local 

 

EXPLANATION

The order of precedence for Group Policy is:

• OU
• Domain

How could leaving a VMware snapshot unattended cause a server down scenario?

How could leaving a VMware snapshot unattended cause a server down scenario?

• Known bug in ESXi 5.0. VMDK file for VM becomes locked when multiple snapshots exist for the same VM
• All remaining storage space on the host becomes used
• The snapshot becomes "unlocked" and causes a hostname/IP conflict
• Trick question, snapshots are good for as long as you need them 

EXPLANATION

Snapshots grow in size over time.  Although the host and VMs may not actually go down, lack of sufficient space on the host would render the host and all hosted virtual machines nearly useless - similar to a CPU and/or memory utilization being maxed out.  Should this occur, access the vSphere client and delete all snapshots.  If you power down the VM, the process will take longer but you will not be able to power up the VM until the process completes.  Leaving the VM powered on will take longer to delete the snapshot but once sufficient space is gained the server(s) should start normal operation again.

VMware introduced Stretch Clusters in vSAN 6.6. Which of the following is NOT true about Stretch Clusters?

VMware introduced Stretch Clusters in vSAN 6.6. Which of the following is NOT true about Stretch Clusters?

• Stretched clusters use fault domains to provide redundancy and failure protection across sites.
• You can use a witness virtual appliance as the witness host in a stretched cluster.
• The witness host can run VMs.
• A vSAN stretched cluster can tolerate one link failure at a time without data becoming unavailable. 

EXPLANATION

The witness host cannot run VMs.
The witness host can be a physical host or an ESXi host running inside a VM. The VM witness host does not provide other types of functionality, such as storing or running VMs.
Multiple witness hosts can run as VMs on a single physical server. For patching and basic networking and monitoring configuration, the VM witness host works in the same way as a typical ESXi host. You can manage it with vCenter Server, patch it and update it by using esxcli or vSphere Update Manager, and monitor it with standard tools that interact with ESXi hosts.

In Attribute Editor what should attribute "msExchRecipient TypeDetails" value be set to for a RemoteSharedMailbox?

In Attribute Editor what should attribute "msExchRecipient TypeDetails" value be set to for a RemoteSharedMailbox?

• 4
• 34359738368
• 1
• 2147483648 

EXPLANATION

Many administrators need to convert regular User Mailboxes to a Shared Mailbox after migration to Office 365. In a Hybrid environment these need to be converted to Remote Shared Mailboxes. Converting a User mailbox to a Shared mailbox in Exchange Online is easy enough, however this does not replicate to Exchange on prem, this can be done by editing
the Attribute value for "msExchRecipient TypeDetail" in Active Directory.  RemoteSharedMailbox attribute value is 34359738368, UserMailbox is 1, SharedMailbox is 4 and RemoteUserMailbox is 2147483648.

Database concurrency control is important for which of the following scenarios?

Database concurrency control is important for which of the following scenarios?

• Maintaining read integrity with multiple users
• Maintaining integrity in a single-user environment
• Maintaining integrity in a multi-user environment
• Maintaining read integrity in a 1-user environment 

 

EXPLANATION

Concurrency control is a process which allows multiple people to access a shared resource, which in this case is a database. There are several different strategies when it comes to configuring your database to prevent data corruption when multiple users are accessing it at the same time that are all called concurrency controls.

Aaron W Originally Copied From

Concurrency control is important for which of the following reasons?

A. To ensure data integrity when updates occur to the database in a multiuser environment B. To ensure data integrity when updates occur to the database in a single-user environment C. To ensure data integrity while reading data occurs to the database in a multiuser environment D. To ensure data integrity while reading data occurs to the database in a single-user environment
