◍ What is the Domain Naming Master and what is its scope? Where should it
be located? How do transfers happen?.
Answer: Forest-wide. The DC responsible for the forest-wide namespace
(aka naming all domains in forest) - MUST be on a DC that is also a Global
Catalog Server. Can be offline without serious repercussions.Transfer
happens through the use of the Active Directory Domains and Trusts tool.
◍ What is DHCP?.
Answer: Dynamic Host Configuration Protocol; dynamically assigns IP
addresses to hosts based on available IP addresses in a shared pool
◍ What are the 3 built-in roles on ESXi hosts? Where can custom roles be
made?.
Answer: Administrator, Read-only, and No Access. Can be made on ESXi
host, but making them on vCenter is preferred.
◍ In terms of SCCM 2012 Capabilities, what is Endpoint Protection?.
Answer: Anti-malware, Firewalls and etc
◍ To use Line Printer Remote (LPR),.
Answer: each client must specify the host and the queue
◍ T/F: FQDN stands for Fully qualified domain name.
Answer: True
◍ 3 A's.
Answer: Authorization, Accounting, Authentication
◍ Host Operating system
, A. Each environment available for O/S installation
B. The operating system installed in a VM
C. In a hosted architecture the O/S in which the virtualization software runs
D. The software the provides the virtualization layer.
Answer: C
◍ Does creating AD groups as "Universal" maximize performance?.
Answer: no, it does not maximize
◍ what does DNS name resolution do.
Answer: a. the task of converting domain names to their corresponding IP
address
◍ What is dynamic DNS?.
Answer: Allows DNS clients to register their hostnames in an assigned
namespace such as DHCP. Reduces need for admins to manually enter
records.
◍ Which of the following FMSO roles has this purpose:Used for backward
compatibility with Windows NT DCs & for propagating password changes
quickly across all DC's in the domain (not hours - but seconds) Should not
be same machine as Global Catalog, ideally
A. Schema Master
B. Infrastructure Master
C. PDC Emulator
D. RID (Relative ID) Master.
Answer: C. PDC Emulator
◍ Can a directory be used as the basis for single sign on?.
Answer: yeah boi it can
◍ Is SCCM on your server by default?.
Answer: no, you have to install it and prepare AD for it
◍ Scope and purpose: infrastructure master.
Answer: scope: domain-wide; purpose: maintains references to objects
located in another domain (phantoms)
,◍ What is a drive?.
Answer: A physical storage mechanism (platters, heads, etc) that has
interconnection hardware.
◍ Imaging.
Answer: Standardized client software installations, including the operating
system
◍ What is the Grandfather, Father, Son (GFS) rotation method?.
Answer: Differential backups daily (the son) followed by one Full backup
each week (the father)The last weekly Full backup is "promoted" to the
monthly backup (the grandfather)
◍ What is application virtualization?.
Answer: App virtualization allows apps to be encapsulated from the
underlying OSApps are installed and configured in a bubble and then the
bubble is made available to clientsThe bubble virtualizes resources such as
environment variables, registry keys, etc. The app bubble is used to execute
the app and deleted when execution is over.All application bubbles reside on
an application server. Some solutions require an agent, others don't.
◍ Logon scripts.
Answer: Run on logon and logoff
◍ The process in which an image is copied to each machine.
Answer: -Reduces the time required to install the operating system and
applications on each machine individually-May require that the machines be
very similar in terms of hardware
◍ What 2 things can be used as a basic block storage?.
Answer: a single drive, or RAID (which is viewed as single block by higher
levels)
◍ What are SRV records? What are their 5 values?.
Answer: key to workstations and servers finding domain controllers1)
Service Name: standard value typically preceded by an underscore such as
, _gc. This is equivalent to the hostname and would be tacked on to the
FQDN of a service2) Server FQDN: This is the server that provides the
service3) Port: This is the TCP or UDP port on which the service is
available. The protocol is signified such as _TCP4) Priority - number-one
priority5) Weight - tiebreaker for priority. Leave it at 0 if you're not
concerned with ties
◍ What is the difference between a site and a domain.
Answer: a. Domain: collection of objects that share the same databaseb.
Site: represent the physical structure or topology of your network. A
collection of well connected sub nets
◍ Define directory.
Answer: A directory is a centralized, hierarchical information repository
about objects in an IT system. Functions to organize and centralize info and
objects.
◍ Having Multiple print queues for a single printer means one can...
Answer: -set permissions on who can use each queue-prioritize jobs from
one queue over another-be used to quickly change between letter and legal
paper by simply printing to a "different" printer
◍ Which command line tool is used for seizure?.
Answer: ntdsutil command line toolcan also be used for transfer but GUI is
preferred
◍ What command displays what is in the Resolver cache?.
Answer: /displaydns
◍ T/F: HOSTS file is located at c:\users\username\etc.
Answer: False: c:\windows\system32\drivers\etc
◍ What is WSH? What does it do? What are its 3 components?.
Answer: a Windows environment to create and execute Windows-based
scripts (Windows Script Host)VBScript (based on Visual Basic) and Jscript
(based on Java) are supported by defaultAutomate parts of the core
operating system using plain text files. Does not require scripts to be
