Question 1	A user calls to report that he is unable to open an attachment within Outlook Express. You determine that Outlook Express has blocked the attachment. What should you do to allow the user to download attachments with a specific file extension? A. From the Options dialog box within Outlook Express, click the Security tab and deselect the option Do Not Allow Attachments to Be Saved or Opened That Could Potentially Be a Virus. B. Using the Folder Options applet within the Control Panel, locate the file extension and deselect the option Confirm After Download. C. From the Options dialog box within Outlook Express, click the Read tab and deselect the option Read All Messages in Plain Text. D. From the Options dialog box within Outlook Express, click the Security tab and change the security zone to Internet zone.
A1:	Answer B is correct. When Outlook Express is configured to block attachments, it will not allow a user to open any attachments that may contain viruses. To enable a user to open attachments with a specific file extension, open the Folder Options applet, locate the file extension from the File Types tab, and deselect the option Confirm After Download. Answer A is incorrect. Deselecting this option means Outlook Express will not block any attachments that may compromise security. Answer C is incorrect. Configuring Outlook Express to read all messages in plain text ensures that any HTML messages that contain code will not be run. Answer D is also incorrect. If you change the security zone to Internet zone, security may be compromised because active content contained in email messages may be run.

Question 6	You are the desktop support technician for a consulting company that has 10 computers running Windows XP. You are responsible for ensuring all computers have the latest critical updates. You do not want to manually download and install the updates. You also do not want updates installed between the business hours of 8 a.m. and 6 p.m. What should you do? A.

Configure Automatic Updates to download automatically and set the schedule anytime between 6 p.m. and 8 a.m. Therefore, answers A and D are incorrect.

Question 7	You are the desktop support technician for a small insurance company. Each computer runs Windows XP. Antivirus software is installed on each computer. A firewall has been configured, and the Automatic Updates feature is enabled on all computers. Updates are downloaded and installed at midnight each day.

Therefore, answers A, B, and C are incorrect.

A8:	Answer A is correct. Microsoft recommends these three steps to securing a computer against virus attacks: use a firewall, install the latest critical updates, and use up-to-date antivirus software. Therefore, you need to install antivirus software on all computers. Answer B is incorrect because MBSA will scan a computer and identify holes in the security. It does not actually protect a computer from viruses. Answer C is incorrect because all computers are enabled to use Automatic Updates. Answer D is incorrect. Although users should be educated about viruses, this knowledge will not physically secure the computers against viruses.

The email messages contain viruses. C. Outlook Express is configured to display all messages in plain text. D. The security zone is set to Internet zone.
A9:	Answer C is correct. If Outlook Express is configured to display all email messages in plain text, any HTML messages may not be displayed properly. Configuring Outlook Express to display all messages in plain text increases security because any functions with the email will not run. Answers A, B, and D are incorrect because these options would not cause the message to be displayed improperly.
