2. What is DHCPv6?

Dynamic Host Configuration Protocol for IPv6 (DHCPv6) is for networks that use IPv6.

13. Name three reasons to have a secondary DNS server.

1. To have a copy of DNS data in case the primary DNS server fails, 2. To enable load balancing, in case the primary DNS server is busy, and 3. To reduce network congestion.

18. Your school has a website with links for each department, such as for Math, Biology, English, Psychology, and so on. Each department wants to maintain its own portion of the site. Which of the following can you set up for each department to maintain its own web files? A. A virtual directory for each department B. A web partition for each department C. A web server for each department D. A web stub zone for each department.

A

4. Your colleague at another company has installed DNS, but it is not mapping computer names to IP addresses. Which of the following might be the problem? (Choose all that apply.) A. DNS lookup zone records are not set up to update automatically and your colleague has not manually created any records. B. There is no WINS-R zone C. The INIT record is missing. D. A single zone database can hold only 100 lookup records and there are over 100 records.

A

7. You work for an environmental consulting company in which most employees work in the field and then come back to the office for a day at a time. Consequently, the company only purchases laptop and tablet computers for its employees to accommodate their travel. When you set up the lease duration in DHCP, which of the following should you use? A. 24 hours B. 8 days C. 16 days D. 24days

A

6. What is a root hint in DNS?

A root hint is a resource record to enable a DNS server to quickly find an authoritative DNS server in a zone that is not on the DNS server, and is used in particular to find an authoritative DNS server on the Internet. When a DNS server receives a query for a domain it does not recognize, it can use the root hint to find that domain on the Internet.

10. Which of the following do you configure when setting up an IPv6 scope on a DHCP server? (Choose all that apply. A. Start and end addresses B. Addresses in the excluded range C. Prefix D. Lease duration

A, B, C, D

12. Which of the following are DNS resource records? (Choose all that apply.) A. Mail exchanger (MX), B. Name server (NS) C. Master browser (MB) D. Service locator (SRV)

A, B, D

15. Your website contains pages of special events. You don't always remember to deactivate these Web pages and some remain available after the event has occurred. How can you prevent the display of Web pages that are no longer current? A. Use the IIS scheduler to deactivate these pages. B. Configure the HTTP response headers function to expire specific documents. C. Configure the web alert feature in IIS to send you a reminder message to remove these pages. D. Use the IIS permission timeout setting to automatically deny the Read permission for a web document to be effective on a specified date.

B

3. Because of budget constraints, your company has only one server. However, when it was purchased it was outfitted with a fast multi-core processor and lots of memory. Often the network connection is the only bottleneck, with a capability of 1 Gbps. What relatively inexpensive addition can you make to the server to address this bottleneck? A. Implement the Network Express network role server. B. Add one or two additional NICs and configure NIC teaming. C. Configure DNS acceleration. D. Configure DNS to not replicate through Active Directory as a way to reduce network overhead.

B

9. The alumni development office at your university uses specialized software that can be accessed from two different servers. The software sometimes experiences slowdowns because it is used by the main alumni development office and by alumni development officers in every department throughout the university. What can you do to help reduce the periodic slowdowns by evenly distributing access of this software between the two servers? A. Use DHCPv6 instead of DHCP B. Configure DNS round robin C. Set up a DNS forwarder D. Configure a DNS balancing zone.

B

16. Which of the following can you accomplish with IIS Manager? (Choose all that apply.) A. Manage streaming media speed. B. Manage ASP .NET C. Manage logging of Web server activities D. Manage server certificates

B, C, D

1. What step can you take when you install a DHCP server to ensure that IP addresses are only assigned by a DHCP server managed by a server administrator in your company? A. Certify the server as a managed container. B. Put a manager lock on the server. C. Authorize the server. D. Duplicate the server's key

C

14. Your large company has several thousand users and multiple DNS and DHCP servers. What tool should you install to better manage this conglomeration of network administration servers? A. Server Manager Plus B. ISCOPE C. IPAM D. Network Binder

C

19. Which of the following applies to a DNS caching server? (Choose all that apply.) A. It eliminates the need to have DNS replication. B. It contains optimized DNS zone databases C. It is used to enable fast DNS queries. and d. It can help reduce the amount of network traffic generated by DNS servers. D. It can help reduce the amount of network trafffic generated by DNS servers.

C

11. The System log on your DHCP server is reporting DHCP database errors. Which of the following can you try first? A. Delete all scopes and recreate them. B. You must delete and reinstall the DHCP server role. C. You have a hung client IP connection. Disable connections to the server and then re-enable connectivity. D. Use the DHCP management tool to reconcile all scopes.

D

5. Your company is located in Atlanta and has a branch location consisting of 35 employees in Greenville, South Carolina. The decision has been made to install a DNS server at the branch location. Which type of DNS server do you recommend installing at the branch location? A. GlobalNames DNS server B. A netcast DNS server C. A primary DNS server D. A secondary DNS server

D

8. Explain stateful autoconfiguration and which Windows Server 2016 role enables use of this technology on a network.

Stateful autoconfiguration means that the computer or network device contacts a DHCP server for a leased IP address. The DHCP server role is used on a Windows Server 2016 server to accommodate stateful autoconfiguration.

17. Which DNS zone holds host address records? Name two types of host address records.

The forward lookup zone holds address records. An IPv4 host record is called a host address (A) resource record and an IPv6 host record is called an IPv6 host address (AAAA) resource record.

20. Users complain that when an error occurs on your website confusing messages are displayed. What IIS feature enables you to address this problem?

Use IIS Manager to configure error pages to display more informative messages.
