Answers

1. ‚	D. When Active/Active clustering is used, you can have two and only two nodes in the Exchange cluster.
2. ‚	C. In an Active/Active cluster, you must not place more than 1,900 mailboxes on each node. This is done to prevent an overloaded situation on the single remaining node in the event that a failover action would occur.
3. ‚	C, D. The minimum ports you must open are port 53 for DNS and port 443 for HTTP over SSL. You should never open port 389 on an external firewall. Port 80 will not be needed for unsecured HTTP connections unless you are planning on placing a public web server in the screened subnet as well.
4. ‚	B, C, D. You can safely disable the Microsoft Exchange Management, Microsoft Exchange MTA stacks, and Microsoft Exchange Routing Engine services on a front-end server for increased security.
5. ‚	B. When Active/Passive clustering is configured on Windows Server 2003 Enterprise Edition or Windows Server 2003 Datacenter Edition, you must have a minimum of two nodes with a maximum of eight nodes.
6. ‚	A, B, C, D. To properly and completely configure the active node of an Active/Passive cluster, you will need to create an IP address resource, a disk resource, an Exchange System Attendant resource, and a network name resource.
7. ‚	D. A single Exchange server can hold only four production storage groups. Thus, when Active/Active clustering is used it is highly recommended that each node hold only two storage groups. Two of the storage groups on the failed node will not be available to clients.
8. ‚	A, D. You will need Exchange Server 2003 Enterprise Edition in order to create Exchange clusters. In addition, only Windows Server 2003 Enterprise Edition or Datacenter Edition can support clusters larger than four nodes.
9. ‚	D. Front-end servers communicate only on port 80 to back-end servers; thus using SSL is not an option. NTLM v2 and Kerberos v5 are network authentication methods .
10. ‚	A, C. You should monitor Active/Active cluster servers for CPU utilization above 40 percent or concurrent mailbox sessions above 1,900 and over 10 minutes long. These items are in addition to the normal monitoring that you would perform on any Exchange server.
11. ‚	D. When Active/Passive clustering is configured on Windows 2000 Advanced Server, you are limited to two nodes total. You must have a minimum of two nodes with a maximum of two nodes.
12. ‚	A. In the Active/Passive mode, the passive node will be able to assume the complete load that the failed active node previously carried; thus all three storage groups will be able to successfully failover to the passive node.
13. ‚	C. You will need one instance for each of the active nodes. To properly and completely configure the active node of an Active/Passive cluster, you will need to create an IP address resource, a disk resource, an Exchange System Attendant resource, and a network name resource.
14. ‚	C. Cluster nodes are kept aware of one another ‚ s existence (and thus their operational state) by the use of a special communication among members that is referred to as a heartbeat.
15. ‚	C. The advantage offered by MSCS clustering is that it is service aware, meaning that it can monitor individual services on a node, not just the status of the node overall.
16. ‚	A. When Active/Passive clustering is configured on Windows 2000 Datacenter Server, you are limited to four nodes total. You must have a minimum of two nodes with a maximum of four nodes.
17. ‚	B. When hot standby is configured, a passive node can take on the resources of any failed active node. Hot standby is really just another term for Active/Passive. You configure for hot standby through a combination of the Preferred Owners list and the Possible Owners list.
18. ‚	C. The failover ring mode, also referred to as Active/Active mode, has each node in the cluster running an instance of the application or resource being clustered. When one node fails, the clustered resource is moved to the next node in the sequence. In Exchange clusters, this mode of operation is not useful because these resources have nowhere else to failover to but the single remaining node in a two-node Active/Active cluster.
19. ‚	A. A single node cluster model cannot be used to provide highly available Exchange resources to clients. It can, however, be used to develop and test cluster processes and procedures for an organization. The single node cluster still retains clustering ability to attempt to restart failed services; thus it mimics a production cluster in this way.
20. ‚	C. NetBIOS names are limited to 15 characters in length.
