| 1. | Tom is the administrator for a company whose Active Directory domain spans four sites: Pittsburgh, Cincinnati, Detroit, and Chicago. He has configured site links to reflect the geography so that replication traffic takes the shortest routes. To that end, Tom configures the site link cost between shorter paths to 200 and the cost between longer paths to 100.
The following week, Tom notices that replication is inconsistent and seems to take longer than it should. What should he check first in troubleshooting this problem?

| 2. | Your company, which has an office in Nashville, has just taken over a smaller company located in Memphis. You have set up a dedicated ISDN line to connect the two offices and added all users and computers in the Memphis office to your company’s domain. You have created sites for both locations and assigned the domain controllers to their respective sites while working from the Nashville location.
A few days later, users in Memphis start complaining about slow logon and resource access. What should you do to speed up access?

| 3. | Charles has consolidated resources in three domains into a single domain that encompasses 800 users and their computers in his company. The previous domains represented offices that are connected by ISDN links.
Charles sets up three sites, one for each office, and configures site links to use SMTP for replicating between the offices. However, the domain controllers in the three offices are unable to replicate with each other. What should Charles do?

| 4. | Shelley is a network administrator for a company that operates a single domain Active Directory network. There are three sites that represent offices located in St. Louis, Detroit, and Chicago. These offices are connected with two T1 links: from St. Louis to Chicago and from Chicago to Detroit. No direct physical connection exists between St. Louis and Detroit. The site links are configured as described in the following table.
Shelley works in the St. Louis office and configures most of the changes to Active Directory from that office. Users in Detroit complain that changes to Active Directory take more than a day to appear in their office. What should Shelley do to ensure that changes made in St. Louis appear in Detroit by the start of the following business day?

| 5. | Brent is a systems administrator for a company that operates a single domain Active Directory network. As a result of corporate expansion, the company is opening a new branch office in a neighboring city. Brent installs a new domain controller and several client computers in the new office, and he sets up a 56Kbps WAN link between the two offices. He needs to make sure that all changes to Active Directory that are configured on head office domain controllers are replicated to the new office domain controller as soon as possible. He also needs to make sure that network traffic over the WAN is kept minimal and that users in the branch office always authenticate to the domain controller in that office.
What should Brent do to meet these objectives?

| 6. | Connie works for a company that has just opened a branch office in a neighboring city that is connected to the head office with an ISDN link. Her manager has requested that replication occur at least once daily during the daytime. However, the line is expected to be close to 90% utilized during the day but only about 30% utilized during night hours.
Connie needs to make sure that replication does not use excessive bandwidth during the day but that at night it will provide adequate bandwidth to complete any synchronization. What should she do to complete this request with the least amount of effort?

| 7. | George is a network administrator for a company that operates an Active Directory domain with three sites representing the company’s offices in Toronto, Ottawa, and Montreal. Each site has three domain controllers, one of which is designated as a preferred bridgehead server. There are direct T1 links from Toronto to Ottawa and from Ottawa to Montreal, each of which is configured as an Active Directory site link. The network is not fully routed, and the default bridging of site links is disabled.
George needs to ensure that changes in Active Directory are properly replicated to all three sites even if any one domain controller in every site fails. What should he do?

| 8. | Kathy is the network administrator for a company that operates an Active Directory network consisting of a single domain and five sites that represent the head office and four branch offices. The branch offices are connected to the head office with ISDN links.
Users at the branch offices inform Kathy that they are experiencing difficulties in locating Active Directory resources that should be available to them. Kathy discovers that replication is configured and working within the head office site, but it is not occurring between sites. There have been no recent outages affecting any of the ISDN links. Which of the following might be the problem? (Choose two answers.)

| 9. | Phil is a systems administrator for a company whose Active Directory network contains two domains and five sites. Concerned that updates to the AD DS database are not reaching all remote sites in a timely fashion, he uses replmon to check the replication parameters and decides that he needs to modify the intersite replication schedules. More specifically, Phil needs to ensure that replication to one remote office connected to the rest of the network with a low bandwidth link takes place only during nonbusiness hours.
Which of the following should Phil do? (Each answer represents part of the solution. Choose two.)

| 10. | Julia is a systems administrator for a large financial company that operates a single-domain network with 75 domain controllers and 20 sites. Although the network has run efficiently since being upgraded from Windows NT 4.0 to Windows Server 2003 several years ago and more recently to Windows Server 2008, Julia has recently noticed that several offices have not received updates to the AD DS database in a timely fashion.
Julia monitors replication and notices that replication takes much longer, as much as 72 hours, to update changes at these sites. Which of the following tools should Julia use to determine the problem? (Choose all that apply.)
