On systems running MS Windows, which OS service manages the print queue?

• Spooler
• LPD
• RAW daemon
• Print manager 

 

EXPLANATION

The spooler service manages print jobs on Windows OS PCs.  Sometimes this service can get "stuck" and otherwise interrupt printing.  A quick and effective troubleshooting idea is to simply stop and restart the service.  This is done through an elevated command prompt:

net stop spooler

Then restart using the following:
net start spooler

Which of the following Powershell commands would give User2 access to User1's calendar? User2 does not currently have access to anything of User1's

Which of the following Powershell commands would give User2 access to User1's calendar? User2 does not currently have access to anything of User1's

• Add-MailboxFolderPermission -Identity User1@contoso.com:\Calendar -User User2 -AccessRights Owner
• Set-MailboxFolderPermission -Identity User1@contoso.com:\Calendar -User User2 -AccessRights Owner
• Set-MailboxPermission -Identity User1@contoso.com:\Calendar -User User2 -AccessRights Owner
• Add-MailboxPermission -Identity User1@contoso.com:\Calendar -User User2 -AccessRights Owner 

 

EXPLANATION

There are two things to notice.  First is that you're trying to give new permissions to User2 and not change current permissions of User2 within User1's mailbox.  So we'll want to use Add instead of Set.  Set is used to change permissions if a user already has some sort of permissions within the mailbox.
The second thing is that the calendar is a folder within the mailbox.  We don't want User2 to be able to read User1's emails, so we'll do Add-MailboxFolderPermission instead of Add-MailboxPermission.

Which of the following languages requires server-side interpretation?

Which of the following languages requires server-side interpretation?

• CFML
• XML
• Java
• CSS 

 

EXPLANATION

ColdFusion Markup Language (CFML) is a scripting language that augments standard HTML files with database commands, conditional operators, high-level formatting functions, and other elements to produce web applications. CFML also includes numerous other constructs, including ColdFusion Components (CFCs), CFML's version of objects, which allow for separation of business logic from presentation.
CFML can be written using either tags or CFScript, which is an ECMA script-style language.
The pages in a CFML application include the server-side CFML tags and functions in addition to HTML tags. Modern CFML applications also tend to have CFCs that are accessed by the CFML pages for executing business logic. When a web browser requests a page in a ColdFusion application, it is automatically pre-processed by the ColdFusion application server.
ability
CFML can also be used to generate other languages,such as XML, JavaScript, and CSS.

Heaps and stacks are affected by which of the following attacks?

Heaps and stacks are affected by which of the following attacks?

• Buffer overflows
• Ping flood
• SQL injection
• Cross site scripting 

 

EXPLANATION

Heaps and stacks are data structures that can be affected by buffer overflows. A buffer overflow vulnerability allows an attacker to corrupt the execution stack of an application by inserting data into adjacent memory locations. This can cause application or operating system instability or, in the hands of a skilled attacker, even allow arbitrary code execution.

SQL Injection is a vulnerability that allows an attacker to query or manipulate a database using user input fields.
Cross site scripting is a vulnerability that allows for an attacker to inject client site scripts into web pages that is intended to be executed by other users.

A ping flood is a method of performing denial of service (DoS or DDoS) against network devices.

Which of the following features of cloud computing matches resources to the current demand?

• Elasticity
• Security
• Redundancy
• Availability 

EXPLANATION

Elasticity refers to the ability of a cloud service to scale on demand. Resources such as storage, bandwidth, or memory can be provisioned in a matter of minutes and scaled down when no longer needed.
