Audit Types	Inventory Audits Facility Audit Operational Audit Efficiency Audit Security Audit
Inventory Audit	Inventory Audits should be done before the network is operational Best performed when all the equipment is in one place
Facility Audit	Facility audit tracks network devices and notes physical location of all network equipment It is best to have network diagram. The diagram should be updated
Operational Audit	This audit looks at daily operational parameters of the network: Network utilization Average # of collisions # of network errors Amount of broadcast traffic
Efficiency Audit	Evaluate performance of network-support staff and network users. Evaluated for their ability to respond to and troubleshoot network problems. Determine if there is sufficient # of adequately trained support personnel.
Security Audit	All that requires limited access to passwords or locks. What virus protection is needed Which files should be backed up What type of emergency and disaster-recovery procedures should be implemented
EMI	Electromagnetic Interference Equipment that interferes with normal operation of computer systems.
SMB is the same as?	CIFS
What is SMB?	A Linux protocol used by Microsoft OS allowing shared access to files and printers.
What is Samba?	Sofware on Linux that provides File/Print services for smb/CIFS clients. Allows Unix servers to communicate with the same networking protocol as Microsoft Windows products
RFI	Radio Frequency Interference
SOAP	Messaging protocol Allows software to run on different OS systems to communicate with each other.
DAS	Direct Attached Storage Storage unit directly connected to a device.
SCSI	Small Computer System Interface Standards for physically connecting and transferring data between devices. Example Raid systems Parallel interface

Gateways	Joining of different systems together to communicate that may use different protocols.
Extranet	A controlled private network that allows access to partners, vendors, and suppliers or an authorized set of customers. Ex. Remote VPN
XML	Is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable
Network Management Elements	Security: Ensuring that the network is protected from unauthorized users. Performance: Eliminating bottlenecks in the network. Reliability: Making sure the network is available to users and responding to hardware and software malfunctions.
Difference between Manager and Agent	Manager polls agents for information. Any alerts are then referred to Managers.
MIB	Management Information Database Are objects that can manage simple network protocols on the agent.
