You need to design a DAG layout for a company with 5000 staff located around
the world. The company has three datacenters, one located in San Francisco, one in
Madrid, and one in Tokyo. Mailbox sizes mean that one server in each site is sufficient
to store the data and a second server is needed for high availability. The network infrastructure
of the company allows all users to access all parts of the network via an MPLS
cloud network, but the fastest links are to the geographically closest datacenter. If the
MPLS network links fail, cross-site connectivity will be broken. What will this Database
Availability Group (or groups) configuration look like to ensure a working solution in
both active and failure scenarios?
- A.Create a single DAG with two servers in each datacenter as members of this DAG with the file share witness in Madrid.
- B.Create two DAGs, one with the PAM and file share witness in San Francisco and the other with the PAM and FSW in Tokyo. Add one server in Madrid to the San Francisco DAG, and the other server to the Tokyo DAG.
- C.Create three DAGs, one for each datacenter and expand the DAG to the nearest other datacenter where an additional server will be placed for site resilience for that primary datacenter of the DAG.
- D.Create four DAGs. One in each datacenter with two servers in it, and then a fourth DAG that holds the replica servers and is distributed geographically across all of the datacenters.

A. Incorrect: This answer does not meet the requirement for a failure scenario because
all of the databases would go online in Madrid in the event of a site outage. B. Incorrect: This answer would result in an outage of servers or sites failing to Tokyo or San Francisco. If the failure was a network failure that isolated Madrid mailboxes, these users would come online in the other data centers and not where the users are located. C. Correct: Each user population needs a DAG that in the event of failure comes online in their nearest datacenter. If a failure occurred in any of the other answers there would be a scenario where some users’ mailboxes would come online in a site that the user could not access. D. Incorrect: This is not a valid DAG design. All servers that hold a replica of a database must be in the same DAG. |

You need to request and install a digital certificate for the four client access servers
that will be used in your Exchange Server 2013 deployment. (Choose all that apply.)
- A.Run New-ExchangeCertificate on each CAS server
- B.From the Exchange Admin Center generate a new certificate request for autodiscover. yourdomain.com
- C.From the Exchange Admin Center generate a new certificate request for autodiscover. yourdomain.com and all of the names used by all of the CAS servers in all of the datacenters
- D.Purchase a UCC digital certificate from a trusted third-party certificate authority
- E.Delete the default certificate configured by the Exchange installation

A. Incorrect: This will create a self-signed certificate on the server that contains the
servers name only and will not be trusted. B. Incorrect: This answer does not include all of the names that the certificate needs to have. C. Correct: This answer is the first part of the answer. The certificate will be used on all CAS servers and so this one certificate needs to have all of the names used by Exchange on it. D. Correct: This answer is the second part of the answer. A trusted certificate needs to be purchased and the request created in C will be used to create this certificate. |

You are creating a plan to ensure that if an Internet link failure occurs at your primary
datacenter, and you successfully move your mailboxes over to the DR site, that all
users will be able to connect. You want to do this with the least IT management tasks
required. (Choose all that apply.)
- A.Ensure that all ExternalURLs for all protocols are mail.contoso.com.
- B.Ensure that OWA has its ExternalURL set to mail.contoso.com but that all other protocols have ExternalURL set to null.
- C.Configure your internal DNS server to have an A record for each CAS server in both sites listed with their own IP address.
- D.Configure your internal DNS server to have an A record for mail.contoso.com that has the IP address of your load balancer that load balances Exchange Servers in the primary datacenter as the IP address of this A record.
- E.Configure your external DNS server to have an A record for each CAS server in both sites listed with their own IP address.
- F.Configure your external DNS server to have the externally NATed IP address of your load balancer that load balances Exchange Servers in the primary datacenter.
- Answer & Explanation

Answer : [A, D, F]
Explanation :
Explanation :
|
A. Correct: Using a single ExternalURL means only two names needed in the certificates.
That will be mail.contoso.com and autodiscover.contoso.com. B. Incorrect: If this were done, only OWA would be available externally. Other protocols like Outlook Anywhere and Exchange Web Services would not be available externally. C. Incorrect: Each CAS server needs to be registered in DNS for management purposes, but for client connectivity you would need to add the Exchange namespace record to DNS as well. D. Correct: This answer ensures that internal users connect to Exchange via the load balancer and not directly or individually to one server via its FQDN. E. Incorrect: This will result in DNS round robin load balancing, which means removing the records manually from DNS when servers stop responding. This requires a lot of hands-on management. F. Correct: This answer ensures that external users connect to the load balancer serving the Exchange Server via the IP address that they can reach from outside of the network. |

Contoso wants to have a 7 day lagged database copy and wants to ensure that their
SafetyNet duration is set to the same value. What command would they use?
- A.Get-TransportService | Set-TransportService -SafetyNetHoldTime 7Days
- B.Get-TransportService | Set-TransportService -SafetyNetHoldTime 7:00.00
- C.Set-TransportConfig -SafetyNetHoldTime 7Days
- D.Set-TransportConfig -SafetyNetHoldTime 7:00:00
- Answer & Explanation
- Report
Answer : [D]
Explanation :
Explanation :
|
A. Incorrect: SafetyNet duration is a global setting and not set per server. The value
for the SafetyNetHoldTime parameter is also incorrect. B. Incorrect: SafetyNet duration is a global setting and not set per server. C. Incorrect: The value of SafetyNetHoldTime is written as a timespan value. Timespan values are Days:Hours:Minutes. This answer uses a string value and so is incorrect. D. Correct: SafetyNet duration is a global setting and not set per server or database. Therefore Set-TransportConfig is used. |
