Microsoft 98-366 Online Questions & Answers

• Question 141:

  This question requires that you evaluate the underlined text to determine if it is correct.

  The process of replicating a zone file to multiple DNS servers is called "zone replication".

  Select the correct answer if the underlined text does not make the statement correct. Select 'No change is needed" if the underlined text makes the statement correct.

  A. Zone transfer
  B. Zone synchronization
  C. Start of authority
  D. No change is needed
  A. Zone transfer

  ---

  DNS zone transfer, also sometimes known by the inducing DNS query type AXFR, is a type of DNS transaction. It is one of the many mechanisms available for administrators to replicate DNS databases across a set of DNS servers

• Question 142:

  Which two of the following are connectivity options for wide area networks (WANs)? (Choose two.)

  A. Token ring
  B. Ethernet
  C. Dial-up
  D. Leased line
  C. Dial-up
  D. Leased line

  ---

  Token ring and Ethernet are used in LANs.

• Question 143:

  HOTSPOT

  For each of the following statements, select Yes if the statement is true. Otherwise, select No. Each correct selection is worth one point.

  Hot Area:

  

  

• Question 144:

  What is the primary purpose of a perimeter network?

  A. to act as a hidden location to deploy network clients
  B. to act as a secure location for deploying highly sensitive network servers
  C. to provide a buffer area between a private intranet and the public Internet
  D. to monitor traffic between routed subnets in a private LAN
  C. to provide a buffer area between a private intranet and the public Internet

• Question 145:

  A service that resolves NetBIOS names to IP addresses is:

  A. Domain Name Service (DNS).
  B. Internet Service Provider (ISP).
  C. Address Resolution Protocol (ARP).
  D. Windows Internet Name Service (WINS).
  D. Windows Internet Name Service (WINS).

  ---

  Windows Internet Name Service (WINS) is Microsoft's implementation of NetBIOS Name Service (NBNS), a name server and service for NetBIOS computer names. Effectively, WINS is to NetBIOS names what DNS is to domain names -- a central mapping of host names to network addresses.

• Question 146:

  What is the default subnet mask for a Class C Internet network?

  A. 255.255.255.252
  B. 255.255.255.240
  C. 255.255.255.192
  D. 255.255.255.0
  D. 255.255.255.0

  ---

  Class A default subnet mask is 255.0.0.0. Class B default subnet mask is 255.255.0.0. Class C default subnet mask is 255.255.255.0.

• Question 147:

  Which of the following is a public IP address?

  A. 10.156.89.1
  B. 68.24.78.221
  C. 172.16.152.48
  D. 192.168.25.101
  B. 68.24.78.221

  ---

  Incorrect:

  The private address space specified in RFC 1918 is defined by the following three address blocks:

  not D: 192.168.0.0/16

  The 192.168.0.0/16 private network can be interpreted either as a block of 256 class C network IDs or as a 16-bit assignable address space (16 host bits) that can be used for any subnetting scheme within the private organization. The

  192.168.0.0/16 private network allows the following range of valid IP addresses: 192.168.0.1 to 192.168.255.254.

  Not A:

  10.0.0.0/8

  The 10.0.0.0/8 private network is a class A network ID that allows the following range of valid IP addresses: 10.0.0.1 to 10.255.255.254. The 10.0.0.0/8 private network has 24 host bits that can be used for any subnetting scheme within the

  private organization.

  Not C:

  172.16.0.0/12

  The 172.16.0.0/12 private network can be interpreted either as a block of 16 class B network IDs or as a 20-bit assignable address space (20 host bits) that can be used for any subnetting scheme within the private organization. The

  172.16.0.0/12 private network allows the following range of valid IP addresses: 172.16.0.1 to 172.31.255.254.

• Question 148:

  Internet Key Exchange (IKE) is responsible for which two functions? (Choose two.)

  A. Establishing network speed parameters
  B. Verifying the client's patch level
  C. Negotiating algorithms to use
  D. Exchanging key information
  C. Negotiating algorithms to use
  D. Exchanging key information

  ---

  Internet Key Exchange (IKE) negotiates the IPSec security associations (SAs). This process requires that the IPSec systems first authenticate themselves to each other and establish ISAKMP (IKE) shared keys.

  In phase 1 of this process, IKE creates an authenticated, secure channel between the two IKE peers, called the IKE security association. The Diffie-Hellman key agreement is always performed in this phase.

  In phase 2, IKE negotiates the IPSec security associations and generates the required key material for IPSec. The sender offers one or more transform sets that are used to specify an allowed combination of transforms with their respective

  settings. The sender also indicates the data flow to which the transform set is to be applied. The sender must offer at least one transform set. The receiver then sends back a single transform set, which indicates the mutually agreed-upon

  transforms and algorithms for this particular IPSec session.

• Question 149:

  Which type of network is most vulnerable to intrusion?

  A. Dial-up
  B. Wireless
  C. Broadband
  D. Leased line
  B. Wireless

  ---

  Insecure Wi-Fi is the easiest way for people to access your home network, leech your internet, and cause you serious headaches with more malicious behavior.

• Question 150:

  Which technology can you use to extend an internal network across shared or public networks?

  A. VLAN
  B. Microsoft ASP-NET
  C. Microsoft .NET Framework
  D. VPN
  D. VPN

  ---

  VPN is a network that is constructed by using public wires -- usually the Internet -- to connect to a private network, such as a company's internal network.
