Choose the benefits of deploying switches over hubs in your infrastructure. (Choose two)
Correct Answer:AB
Switches differ from hubs in that they break up Collision Domains. Each port on a switch equals one Collision Domain. Therefore, a switch will lower the number of collisions within the infrastructure. Managed switches typically offer the ability to create Virtual LANs. Virtual LANs allow the switch to create multiple LANs/network segments that are Virtual. This allows the switch to create additional environments where needed.

You work as a Network Administrator for Tech-E-book Inc. You are configuring the ISA Server 2006 firewall to provide your company with a secure wireless intranet. You want to accept inbound mail delivery though an SMTP server. What basic rules of ISA Server do you need to configure to accomplish the task.
Correct Answer:A
Publishing rules are applied on SMTP servers to accept inbound mail delivery. There are three basic rules of ISA Server, which are as follows: Access rules: These rules determine what network traffic from the internal network is allowed to access the external network. Publishing rules: These rules are used for controlling access requests from the external network for the internal resources. These types of rules are usually applied to Web servers that are used for providing public access. These are also applied on SMTP servers to accept inbound mail delivery. Network rules: These rules define the traffic source, traffic destination, and the network relationship. Answer D is incorrect. These rules are set for controlling outbound traffic. Answer B is incorrect. These rules define how to handle the traffic. Answer C is incorrect. There are no such ISA Server rule sets.

Which of the following statements are true about WPA?
Correct Answer:ABCD
WPA stands for Wi-Fi Protected Access. It is a wireless security standard. It provides better security than WEP (Wired Equivalent Protection). Windows Vista supports both WPA-PSK and WPA-EAP. Each of these is described as follows: WPA-PSK: PSK stands for Preshared key. This standard is meant for home environment. WPA-PSK requires a user to enter an 8- character to 63-character passphrase into a wireless client. The WPA converts the passphrase into a 256-bit key. WPA-EAP: EAP stands for Extensible Authentication Protocol. This standard relies on a back-end server that runs Remote Authentication Dial-In User Service for user authentication. Note: Windows Vista supports a user to use a smart card to connect to a WPA-EAP protected network. Shared- key WPA is vulnerable to password cracking attacks if a weak passphrase is used. To protect against a brute force attack, a truly random passphrase of 13 characters (selected from the set of 95 permitted characters) is probably sufficient.
