• Question 272:

  Which of the following types of Network Address Translation (NAT) uses a pool of public IP addresses?

  A. Static NAT
  B. Port Address Translation (PAT)
  C. Dynamic NAT
  D. Cache NAT
  C. Dynamic NAT

  ---

  Dynamic Network Address Translation (NAT) uses a pool of public IP addresses. Dynamic NAT is a technique that maps an unregistered IP address to a registered IP address from a group of registered IP addresses. It also establishes a one-to-one mapping between unregistered (private) and registered (public) IP addresses, but the mapping varies depending on the registered address available in the IP address pool at the time of connection. Answer: A is incorrect. Static NAT performs a manual translation of one IP address to a different one. Static NAT is typically used to translate the destination IP address in packets that reach to the translation device (such as a router) for LAN. In static translation type, a manual translation is performed between two addresses and possibly port numbers. Answer: B is incorrect. Port Address Translation (PAT) is also a type of NAT. This type of NAT is used in home networks that are using DSL or cable modems. It is designed to provide Internet access to many internal users through one external address. Answer: D is incorrect. There is no such type of NAT as Cache NAT.

• Question 275:

  All your domain controllers are configured for DHCP. Each time the system is booted, it gets a new IP address from the DHCP server. You had also configured the Active Directory on the domain controllers. You want to configure your DNS settings so that it will dynamically update DNS data whenever the IP address of a domain controller changes. How will you configure for dynamic updates?

  A. Configure the DNS server for dynamic updates.
  B. Configure the DHCP server for DNS dynamic updates.
  C. Configure each domain controller for Dynamic update.
  D. Configure the Active directory for dynamic updates.
  B. Configure the DHCP server for DNS dynamic updates.

  To enable DNS dynamic updates in the DHCP server, open the DHCP console, and then, open the Properties dialog box for the DHCP server. Select the Enable dynamic update of the DNS client information check box in the Dynamic DNS tab. Then, select the Update, according to client request option, to allow the DHCP client computer to update A (host) resource record, and the DHCP server to update the PTR (pointer) resource record.If you want to allow the DHCP server to update both A (host) and PTR (pointer) resource records regardless of the DHCP client computer's request, select Always update forward and reverse lookups option.

• Question 276:

  Ron owns the domain TechPerfect.net. He often receives bounces about messages he didn't send. After looking at all such mails, he is sure that someone is spamming e- mails and using his domain name. What will Ron do to ensure that his domain name is not exploited?

  A. Publish the MX record for the domain.
  B. Publish the SPF record for the domain.
  C. Publish the AAAA record for the domain.
  D. Publish the A record for the domain.
  B. Publish the SPF record for the domain.

  Sender Policy Framework (SPF) is an e-mail validation system designed to prevent e- mail spam by tackling source address spoofing. SPF allows administrators to specify which hosts are allowed to send e-mail from a given domain by creating a specific SPF record (or TXT record) in the public Domain Name System (DNS). Mail exchangers then use the DNS to check whether that mail from the given domain is being sent by a host sanctioned by that domain's administrators. Answer: A, D, and C are incorrect. These records do not help prevent domain names from being exploited by hackers.
