Microsoft 98-366 Online Questions & Answers

• Question 91:

  Which of the following are features of DHCP? (Choose two.)

  A. IP address resolution to canonical names
  B. Secure shell connections
  C. Address reservation
  D. Network file transfer
  E. IP address exclusion
  C. Address reservation
  E. IP address exclusion

  ---

  *

  The Dynamic Host Configuration Protocol (DHCP) is a standardized network protocol used on Internet Protocol (IP) networks for dynamically distributing network configuration parameters, such as IP addresses for interfaces and services.

  *

  Some network devices need to use statically assigned IP addresses rather than addresses dynamically assigned through DHCP. For example, DHCP servers must have statically configured IP addresses. Also, some devices (such as

  legacy network printers) do not support DHCP.

  For the devices that need static IP assignments, the company creates an exclusion range from each IP address range.

• Question 92:

  Which protocol can be used to encrypt packets on the Internet?

  A. SNMP
  B. HTTPS
  C. TFTP
  D. HTTP
  B. HTTPS

  ---

  HTTPS, which stands for Hypertext Transfer Protocol Secure, makes it more difficult for hackers, the NSA, and others to track users. The protocol makes sure the data isn't being transmitted in plain-text format, which is much easier to eavesdrop on.

• Question 93:

  To directly connect the Ethernet network interface cards (NICs) of two computers, you should use a: A. Crossover cable

  B. Straight cable
  C. Rollover cable
  D. Coaxial cable
  A

  ---

  An Ethernet crossover cable is a type of Ethernet cable used to connect computing devices together directly. Normal straight through cables were used to connect from a host network interface controller (a computer or similar device) to a network switch, hub or router.

• Question 94:

  The default subnet mask for a Class B network is:

  A. 0.0.0.255
  B. 0.0.255.255
  C. 255.0.0.0
  D. 255.255.0.0
  D. 255.255.0.0

  ---

  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 95:

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

  To set lower security settings in Internet Explorer for an extranet site, add the site's URL to the "Local Intranet "zone.

  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. Internet
  B. Trusted Sites
  C. Extranet Sites
  D. No change is needed
  B. Trusted Sites

  ---

  Trusted sites

  The level of security set for Trusted sites is applied to sites that you have specifically indicated to be ones that you trust not to damage your computer or information.

  Reference: Change Internet Explorer Security settings

• Question 96:

  You are helping a friend set up a public-facing web server for a home office.

  Your friend wants to protect the internal network from intrusion.

  What should you do?

  A. Set the web server in a perimeter network.
  B. Set the web server to block access on ports 80 and 443.
  C. Configure the firewall to block access on ports 80 and 443.
  D. Set the IP address of the web server to be within the LAN.
  A. Set the web server in a perimeter network.

  ---

  In computer security, a DMZ or demilitarized zone (sometimes referred to as a perimeter network) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger and untrusted network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN); an external network node only has direct access to equipment in the DMZ, rather than any other part of the network.

• Question 97:

  VPNs are implemented to provide:

  A. A secure connection within a private network.
  B. A secure connection through public networks.
  C. Additional encryption by using IPSec.
  D. Additional security for selected computers.
  B. A secure connection through public networks.

  ---

  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.

  There are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

• Question 98:

  The maximum throughput of an 802.llg network is:

  A. 2.4 GHz.
  B. 54 GHz.
  C. 2.4 Mbps
  D. 54 Mbps.
  D. 54 Mbps.

  ---

  The 802.11g standard for wireless networking supports a maximum bandwidth of 54 Mbps.

• Question 99:

  Which network does the IP address 220.100.100.100 belong to?

  A. 220.100.100.0/24
  B. 220.100.100.1/24
  C. 255.255.255.0/24
  D. 255.255.255.1/24
  A. 220.100.100.0/24

• Question 100:

  What are two characteristics of a mesh network topology? (Choose two.)

  A. It is fault tolerant because of redundant connections.
  B. Every node connects to every other node on the network.
  C. It works best for networks with a large number of nodes.
  D. It requires less cabling than either a star or ring topology.
  A. It is fault tolerant because of redundant connections.
  B. Every node connects to every other node on the network.

  ---

  In a (full) mesh network topology, each of the network node, computer and other devices, are interconnected with one another. Every node not only sends its own signals but also relays data from other nodes. In fact a true mesh topology is the one where every node is connected to every other node in the network. This type of topology is very expensive as there are many redundant connections, thus it is not mostly used in computer networks. It is commonly used in wireless networks.
