How should you ensure that the Active Directory design will accommodate Exchange 2000 Server?

• A.Define each location as a Microsoft Windows 2000 site. Configure one domain controller in each location as a global catalog Server.
• B.Define the single domain at a Microsoft Windows 2000 site. Configure one domain controller in each location as a global catalog Server.
• C.Define each location as a Microsoft Windows 2000 site. Configure the domain controller in Chicago as global catalog Server for all locations.
• D.Define the single domain at a Microsoft Windows 2000 site. Ensure there is a single global catalog Server in Chicago, which is used by all of the regional offices.

How should you design a recovery solution that fulfills the archiving requirements?

• A.Ensure that circular logging is disabled on all servers. When a restore is required, perform the following steps:
  * Restore the information store that must be recovered.
  * Mount the information store, and replay the transaction logs.
  * Re-create the index for the information store if required.
• B.Ensure that circular logging is enabled on all servers. When a restore is required, perform the following steps:
  * Restore the storage group that contains the information store that must be recovered.
  * Mount the information store.
  * Re-create the index for the information store if required.
• C.Ensure that circular logging is enabled on all servers. When a restore is required, perform the following steps:
  * Restore the storage group that contains the information store and the index that must be recovered.
  * Mount the information store and the index.
• D.Ensure that circular logging is disabled on all servers. When a restore is required, perform the following steps:
  * Restore the information store and the index that must be recovered.
  * Mount the information store and the index, and replay the transaction logs.

Which two actions should you perform to implement e-mail for customers who want to have their own e-mail domain? (Choose two)

• A.Create a new recipient policy to add the appropriate domain alias to the SMTP address for each mailbox user.
• B.In the DNS zone file for the customer's zone, create an MX record that points to the Fabrikam Inc. mail server that hosts the customer's domain.
• C.Create a new POP3 virtual server to host the customer's domain.
• D.Create a new SMTP virtual server to host the customer's domain.
• E.Create a new web site to host the customer's domain.
• F.In the DNS zone file for the customer's zone, create a CNAME record that points to the Fabrikam Inc. mail server that hosts the customer's domain.
• G.In the DNS zone file for the customer's zone, create an A record that points to the SMTP virtual server that hosts the customer's domain.

How should you design the backup strategy to allow the recovery from a corrupted database?

• A.Back up each Exchange database separately.
• B.Back up each Exchange storage group separately.
• C.Back up drive M on each Exchange 2000 Server computer.
• D.Back up the Exchange 2000 Server computer offline.

Contoso, Ltd's connection to Outlook web Access is shown in the Exhibit.

正解：

Explanation:
In a perimeter DMZ configuration to permit access to OWA from internet we just need to permit the http port in this case 80 and 448.
From the external firewall to our internal we needed to permit the others Reference:

Configuring Firewalls
Chapter 10 - Planning Outlook Web Access Servers
Firewall Integration
This section focuses on firewall planning. You will need to communicate with the relevant individuals or departments to ensure that you have planned for your firewall(s) to accommodate your FE/BE server topology.
Front End behind Firewall
As outlined earlier in this chapter, if OWA is being accessed from the Internet, your front-end server is likely to be behind a firewall. The services and ports that will need to be enabled are listed in Firewall Integration Table 1.
Table 1. Firewall Configuration: Front End Behind Firewall
Source Destination Service Protocol and Port
Internet / External Network Internal/Private Network HTTP TCP 80
HTTP TCP 443
IMAP4 TCP 143
IMAP4TLS TCP 993
Front-End on Perimeter Network
If you plan to deploy your front-end server on a perimeter network (as outlined earlier in this chapter), there must be two firewalls. The services and ports that must be enabled are listed in Firewall Integration Table 2.
Table 2. Front-End Server(s) in a Perimeter Network
Source Destination Service Protocol and Port
Internet / External Network Perimeter Network HTTP TCP 80
HTTP TCP 443
IMAP4 TCP 143
IMAP4TLS TCP 993
Perimeter Network Internal/Private Network DNS TCP, UDP 53
HTTP TCP 80
RPC EP Mapper TCP 135
KERBEROS TCP UDP 88
LDAP TCP 389
NETLOGON TCP 445
DS Access (GC) TCP 3268
TCP High Ports TCP 1024+
If your security policy does not permit one or more of these services through the firewall, it is possible to statically configure services such as DNS and RPC to reduce the number of ports.
