In PowerShell, all of the following are valid ways to create an array, except:

• $array = %('this, 'that')
• $array = @('this', 'that')
• $array = ('this', 'that')
• $array = [array]('this', 'that') 

EXPLANATION

In programming, arrays are collections of items.  In PowerShell, these items are always objects, and a single array can contain different, unrelated object types.
Typically, simply putting a comma between different items causes them to be treated together like an array.  You can also explicitly declare an array with the [array] type marker, or with the shorthand "@" symbol.
In PowerShell, the "%" symbol is an alias for "Foreach-Object", and the example above will throw an error.
Fun fact: in Perl, the "%" is used to declare a variable as a hashtable, which is similar to an array, but uses a named key index instead of an automatic number index; unlike in PowerShell, the variable prefix in Perl actually changes depending on use, so a hashtable variable would look like "%variable" instead of "$variable".

Which of the following is NOT a feature of the Microsoft Exchange 2016 Transport Pipeline?

Which of the following is NOT a feature of the Microsoft Exchange 2016 Transport Pipeline?

• Transport service
• Mailbox transport
• Back end transport service
• Front end transport service 

 

EXPLANATION

The Microsoft Exchange Transport Pipeline uses the following services:

• Front end transport service, which does basic message filtering based on domains, connectors, senders and recipients. It only connects with the transport service on a mailbox server and does not backlog any messages locally
• Transport service, which runs on all mailbox servers, and handles SMTP mail flow. It helps in message categorization and content inspection. The transport services routes messages between the Mailbox Transport service, the Transport Service and Front End Transport service.  This service does not queue messages locally
• Mailbox Transport, which handles receiving and sending SMTP to the transport service from the mailbox using remote procedures calls (RPCs).

Which of the following best describes a network-based intruder prevention system (NIPS)?

Which of the following best describes a network-based intruder prevention system (NIPS)?

• Detects and takes actions against threats
• Provides a sweet diversion from life's little irri
• Identifies zero-day vulnerabilities
• Detects and eliminates threats 

 

EXPLANATION

A network-based intruder prevention system attempts to detect and mitigate threats by taking action to block them. While it may be able to identify a zero-day vulnerability using anomaly-based signatures, this is not its primary function.

What is the disk fault tolerance in a minimally sized RAID 50 array?

What is the disk fault tolerance in a minimally sized RAID 50 array?

• 1 MAX
• 3 MAX
• NONE
• 2 MAX 

EXPLANATION

RAID 50, also called RAID 5+0, combines the straight block-level striping of RAID 0 with the distributed parity of RAID 5. As a RAID 0 array striped across RAID 5 elements, maximum fault tolerance is 1 in each RAID 5. Then the maximum fault tolerance is 2.

Windows 10 offers four (4) different update branches that describe every update parameter; from the applicable edition of Win. 10 to the length of support for the update, (5-yrs, 10-yrs, etc). Which of the following is NOT one of these branches?

Windows 10 offers four (4) different update branches that describe every update parameter; from the applicable edition of Win. 10 to the length of support for the update, (5-yrs, 10-yrs, etc). Which of the following is NOT one of these branches?

• Current Branch for Business
• Long Term Servicing Branch
• Windows Insider Preview Branch
• Open grade 

 

EXPLANATION

Upgraded builds of Windows 10, known as feature updates,[199] are occasionally released, containing new features and other changes; in April 2017, Microsoft stated that in the future, these updates would be released semi-annually every March and September.[200]
The pace at which feature updates are received by devices is dependent on which release channel is used; the default branch for all users of Windows 10 Home and Pro is "Current Branch", (CB) which receives stable builds after they are publicly released by Microsoft. A 60-day grace period is provided for each CB build to be rolled out to users before Microsoft ends support and updates for the previous version.[199] Windows Insider branches receive unstable builds as they are released, at either a "Fast" pace (immediately after release) or "Slow" pace (slightly delayed from their "Fast" release). The Pro and Enterprise editions may optionally use the "Current Branch for Business" release channel (CBB), which receives the stable builds on a roughly four-month delay from their CB release to allow for additional testing.[199][191][201] CBB may defer build upgrades for up to eight months, after which the new build must be installed in order to maintain support and access to security updates.[197] Administrators can also use the "Windows Update for Business" system to organize structured deployments of updates and build upgrades across their networks.[191]
Enterprise licensees may use the Windows 10 Enterprise Long-term Servicing Branch (LTSB) edition.[199][201] LTSB milestones of Windows 10 are designed for long-term deployments in specialized environments, and only receive quality of life updates (i.e. security patches). Each LTSB milestone is given a full, 10-year support lifecycle. Due to Microsoft's intended use cases for LTSB builds, certain features, including most Cortana functionality, Windows Store, and bundled apps, are excluded from LTSB.[199][175][202][203]Microsoft director Stella Chernyak explained that "we have businesses [that] may have mission-critical environments where we respect the fact they want to test and stabilize the environment for a long time."[204]
