Annex C
What is an Active Directory Forest?
A collection of one or more domains.
What is server clustering?
A group of server that work together as a single hosting solution that has a single IP address and hostname. The servers in a server cluster are called nodes.
What is a hypervisor?
A hypervisor creates the virtualization layer that makes server virtualization possible.
Explain the difference between a type 1 and type 2 hypervisor?
A type 1 hypervisor needs hardware. Type 2 hypervisors live in the OS.
What is the difference between a virtual host and a virtual machine?
A virtual host is a physical server with the virtualization layer. A virtual machine is the individual OS running on the virtual host.
What does an IMT 48 do?
Admin Token
What is an Organizational Unit?
Allows for the domain controller to organize objects on the domains.
What are the advantages of RAID 10?
Benefits from fault tolerance of RAID 1 and the speed of RAID 0.
Disadvantages of RAID 10?
Can only use 50% of data storage.
What method does RAID 10 use?
Combines RAID 1 and 0.
What is Distributed Resource Scheduler?
DRS is a feature that balances workloads across clusters of EXSi hosts.
What feature prevents and detects data breaches?
Data Loss Prevention (DLP)
What does an IMT 44 do?
Data Transfer Authority
What method does RAID 0 use for storing data?
Data is "striped" across multiple disks.
What method does RAID 1 use for storing data?
Data is copied on more than 1 disk.
What method does RAID 5 use for storing data?
Data is striped across multiple disks along with parity.
What are the three storage types and what are their features?
Directly-Attached Storage(DAS); i.e. external hard drive Network Attached Storage(NAS); i.e. A single server integrated in the LAN Storage Area Network(SAN); i.e. TACLAN
Define Trust Relationships?
Domains can extend authentication servers to user in domains outside their forest.
What is an object?
Entities that represent a resource such as users, computers, or printers.
What is a domain?
Falls under the forest. Allows for network-wide user identity, authentication, trust relationships, and replication.
Explain the Logical Model.
Forest Domains Organizational Units
What is the hierarchy of SOCOM's domains?
Global Enterprise Operation Center(GEOC) Component Network Controlled Center(CNCC) Theatre Network Control Center TNCC Consolidated Support Desk (CSD) Local Help Desk
Define high availability?
HA is the ability of a system to operate continuously for a designated period of time when components with the system fail.
Examples of type 1 hypervisors?
Hyper-V ESX/ESXi XenServer
What is load balancing?
Load balancing distributes workloads between two or more computers.
What is the nomenclature of AN/TSR-11?
Next Generation Receive Terminal (NGRT) Type 1 Receive Broadcast Manager Type 2 Receive Broadcast Manager
What is parity in RAID 5?
Parity is used to re-create a disk in the event of a disk failure.
What is the disadvantage of using RAID 5?
Parity reduces the collective amount of data that can be stored.
What is the PNOC?
Permission Network Operations Center
Which type of RAID has the fastest speeds?
RAID 0
Which type of RAID is not fault tolerate?
RAID 0
What does RAID stand for?
Redundant Array of Independent Disks
How many disks is required for RAID 5?
Requires 3 or more disks.
What does SIE stand for?
SOF Information Environment
Define server virtualization.
Server Virtualization makes it possible for the OS of a physical server to run on a virtual layer (the hypervisor)
What is SSO?
Single sign-on is a session and user authentication that provides a user to use a set of login credentials.
What are site selection requirements of GBS?
Slopes no greater than 30 degrees and winds no greater than 30 mph.
What does an IMT 12 do?
System Account Request
Why would an administrator use replication?
To replicate sufficient data between domain controllers.
what are the three segments of GBS?
Transmit, Space, Recieve
What features does vCenter allow?
VM Cloning, vMotion, HA, Fault Tolerance, DRS
What does vCenter do?
VMware vCenter Server provides a centralized platform for managing your VMware vSphere environments.
What is network user-identity?
When a domain creates a user, the user can be referenced on any computer in the forest.
Examples of type 2 hypervisors?
Workstation Virtual Server Fusion
What is a synonym for a type 1 hypervisor?
bare-metal hypervisor
What is vMotion?
vMotion allows for the live migration of VMs from one physical server to another without any interruption in service.
