  Your company has an IPv6 network that has 25 segments. You deploy a server on the IPv6 network.

  You need to ensure that the server can communicate with all segments on the IPv6 network.

  What should you do?

  A. Configure the IPv6 address as fd00::2b0:d0ff:fee9:4143/8.

  D. Configure the IPv6 address as 0000::2b0:d0ff:fee9:4143/64.
  A. Configure the IPv6 address as fd00::2b0:d0ff:fee9:4143/8.

• Question 265:

  Your network contains two DHCP servers named Server1 and Server2. On Server1, you create a scope named Scope1. You need to ensure that DHCP clients receive IP addresses from the address range in Scope1 if Server1 is unavailable.

  The solution must prevent both servers from assigning duplicate IP addresses.

  What should you do from the DHCP console?

  A. On Server1, create a superscope.
  B. On Server1, select Scope1, and then run the Split-Scope wizard.
  C. On Server2, create a scope, and then reconcile each scope.
  D. On Server2, create a scope, and then enable Network Access Protection.
  B. On Server1, select Scope1, and then run the Split-Scope wizard.

• Question 266:

  You need to create a sender policy framework (SPF) record for the e-mail servers on your network. Which type of resource record should you create?

  A. Alias (CNAME)
  B. Host Information (HINFO)
  C. Signature (SIG)
  D. Text (TXT)
  D. Text (TXT)

  Authenticating Outbound E-Mail:

  Domain holders need to complete an inventory and publish all IP addresses of their outbound e- mail servers in the DNS zone file. This is an administrative step that requires no changes to an organization's e-mail or DNS software. Even if

  your domain has no outbound e-mail servers, you can help protect your domain from spoofing by publishing an SPF record in the DNS that states this. Follow the steps below to create and publish an SPF record for each domain name that

  your organization owns.

  1.

  Determine the IP addresses of the outbound e-mail servers for the domain.

  2.

  Identify the e-mail servers that transmit outbound e-mail for all of the domains and subdomains in your organization, as well as the IP addresses for these servers. You will need to publish a Sender ID record for each of them. If your organization uses any third parties to send e- mail on its behalf, such as an e-mail service provider or a hoster, you will also need to know their domain names. However, you do not need to know the IP addresses of their outbound e-mail servers. (You may want to encourage them to publish Sender ID records for their own domains.)

  3.

  Create the SPF record. You can use the Sender ID Wizard described in this document to make it easier. (See www.microsoft.com/senderid/wizard.) Note You must create a separate SPF record for each domain and subdomain that sends e-mail for you. It is possible for several domains to share the same Sender ID record.

  4.

  After you have created the SPF records for your organization, publish them in DNS TXT records. You may need the assistance of your DNS administrator, Web hoster, or registrar.

  5.

  Ensure that your domain can be correctly identified as the purported responsible domain (PRD) for each message you send. This means that the sender's domain must be shown in certain headers of the e-mail message. Sender ID has been carefully designed to ensure that most legitimate e-mailers, remailers, and mailing list operators already satisfy this requirement. In a few cases, such as mail forwarding services, you may need to add additional headers to e-mail messages.

• Question 267:

  You need to add a reservation for a print device to a DHCP scope. Which two components should you include in the reservation? (Each correct answer presents part of the solution. Choose two.)

  A. the default gateway
  B. the IP address
  C. the MAC address
  D. the printer server name
  E. the subnet mask
  B. the IP address
  C. the MAC address

  ---

  A reservation reserves an IP address based on the MAC address.

• Question 268:

  Your network contains an Active Directory forest. The forest contains two domains named contoso.com and nwtraders.com. You have a DNS server named DNS1. DNS1 hosts Active Directory-integrated zones for contoso.com and nwtraders.com. You discover that client computers in contoso.com cannot use single-label names to access servers in nwtraders.com. You need to ensure that contoso.com computers can access nwtraders.com servers by using single-label names.

  What should you modify?

  A. the DNS suffix search order on DNS1
  B. the DNS suffix search order on the client computers
  C. the root hints servers on DNS1
  D. the security settings of the nwtraders.com zone
  B. the DNS suffix search order on the client computers

• Question 269:

  Your network contains a Windows Server Update Services (WSUS) Server infrastructure that has three servers named WSUS1, WSUS2, and WSUS3.

  WSUS2 is a downstream replica server of WSUS1. WSUS3 is a downstream replica server of WSUS2. You need to ensure that the Update Services console on WSUS2 only displays computers that receive updates from WSUS2.

  What should you configure on WSUS2?

  A. downstream servers
  B. Personalization
  C. reporting rollup
  D. synchronizations
  B. Personalization
