Question 1 of 168
You have three Hyper-V hosts that each have 20 processor cores and 64 GB of RAM. Nine virtual machines are deployed to the hosts as shown in the following table.
Exam 70-345: Question 1 - Image 1
Host1 is located in New York, Host2 is located in Los Angeles, and Host3 is located in Denver. None of the virtual machines use dynamic memory.
You plan to deploy a two-node Exchange Server 2016 database availability group (DAG) by using the virtual machines. Each node will have 12 processor cores and 24 GB of memory.
You are evaluating whether you can use the existing servers for the deployment or whether you must purchase additional servers.
You need to recommend where to place the Exchange servers. The solution must minimize costs.
What is the best recommendation to achieve the goal? More than one answer choice may achieve the goal. Select the BEST answer.
Answer

Suggested Answer

The suggested answer is D.

To deploy the two Exchange Server 2016 nodes, each requiring 12 processor cores and 24 GB of memory, you need to evaluate the available resources on each Hyper-V host. Host1 has 12 unused cores and 44 GB of unused memory, which means it can support one Exchange server. Host2 has 0 unused cores but 16 GB of unused memory, and Host3 has 0 unused cores but 20 GB of unused memory, meaning that both cannot support an additional Exchange server due to insufficient cores. Therefore, utilizing Host1 and needing another existing server with sufficient resources, Host2 remains the best candidate since it has the next highest availability. Hence, deploying one Exchange server on Host1 and one on Host2 is the optimal solution to minimize costs without purchasing additional servers.

Question 2 of 168
You have an Exchange Server 2016 organization. The organization contains five Mailbox servers. The servers are members of a database availability group
(DAG). All of the databases in the DAG are replicated to all of the members.
You plan to perform scheduled maintenance on a Mailbox server named MBX3 that will place the server offline for up to an hour.
You need to ensure that any active databases on MBX3 are activated on other DAG members before performing the maintenance.
Which cmdlet should you use?
Answer

Suggested Answer

The suggested answer is D.

To ensure that any active databases on MBX3 are activated on other DAG members before performing the maintenance, you should use the `Set-MailboxServer` cmdlet with the `DatabaseCopyActivationDisabledAndMoveNow` parameter. This will disable the activation of the mailbox database copies on the specified server and move any active databases to other available servers within the DAG. This cmdlet ensures a smooth transition of database activation without downtime.

Question 3 of 168
You have an Exchange Server 2016 organization. The organization contains a database availability group (DAG).
You need to identify the number of transaction logs that are in replay queue.
Which cmdlet should you use?
Answer

Suggested Answer

To identify the number of transaction logs that are in the replay queue for a database availability group (DAG) in an Exchange Server 2016 organization, the cmdlet Get-MailboxDatabaseCopyStatus should be used. This cmdlet provides detailed information about the status of mailbox database copies, including the replay queue length, which indicates the number of transaction logs waiting to be replayed into the passive copy of the database.

Question 4 of 168
Your company has a data center. The data center contains a server that has Exchange Server 2016 and the Mailbox server role installed. Outlook Anywhere clients connect to the Mailbox server by using the name outlook.contoso.com.
The company plans to open a second data center and to provision a database availability group (DAG) that spans both data centers.
You need to ensure that Outlook Anywhere clients can connect if one of the data centers becomes unavailable.
What should you add to DNS?
Answer

Suggested Answer

The suggested answer is A.

To ensure that Outlook Anywhere clients can connect if one of the data centers becomes unavailable, you need to add an A record to DNS. An A record maps a domain name to its corresponding IP address, allowing clients to resolve the domain name to the IP address of the server. By adding one A record, you can provide the necessary DNS entry that points to the Mailbox server's IP address, facilitating client connection even in the event of a data center failure.

Question 5 of 168
HOTSPOT -
You deploy a server named ex01.contoso.com that has Exchange Server 2016 installed.
You need to ensure that when users connect to the URL of http://ex01.contoso.com, they access Outlook on the web over a secure connection.
How should you configure the Default Web Site? To answer, select appropriate options in the selected area.
