answers new!! 2025/2026 updated new!!
An HBA (Host Bus Adapter) Is commonly used fore which protocol?
FC
Name one of the more common File Systems that a NIC (network interface card) is used with?
NFS (Network File System)
What is the primary benefit of blade servers?
High density
What type of server is op%mized for density?
Blade server
When a write from a SAN host is received, where is it first wri(en?
NVRAM
When boo%ng a Host from FC SAN, what's one of the things you should keep in mind?
Each host has to have its own LUN
Name some protocols commonly used in SAN block.
iSCSI, FC and FCoE (or oF)
What must be done in a FC SAN environment for a host to see a storage LUN?
WWN zoning or port zoning
A host connected through FC SAN, suddenly loses access to mul%ple volumes. Where should
you first start troubleshoo%ng?
Layer 1 (cable and SFP)
What is gained from configuring Mul%path on a host?
Link reliability to the LUN is improved
What's one thing you can do to improve FC throughput?
Increase transmission speeds by adding faster HBAs and op%cs. (upgrade 8Gb to 16Gb)
What's one thing you could do to increase iSCSI throughput?
, Install a faster switch
Can a SAN storage LUN be shared and wri(en to by mul%ple ini%ators without data corrup%on?
Yes, One of the major features of File and object are to share the same LUN to mul%ple hosts.
FC is primarily used for...
Block storage (system access)
Managed ETH switches are more appropriate for...
VLAN configura%ons
Unmanaged ETH switches have featured...
Plug'n'play DSCP
What's the most commonly used transmi(er in FC?
SFP and SFP+
What's the most commonly used transmi(er in ISCSI?
SFP and SFP+
What is MTU?
(Max Transmission Unit) - Max packet size that can be transmi(ed
What's the primary advantage of using Jumbo frames?
More data in less packages (bigger data packet)
How may speeds can an SFP nego%ate?
3 speeds
Which is not a component of FC SAN?
Switch, ini%ator, target, and firewall.
Firewall
Disadvantage of FC SAN
Cost
Advantage of iSCSI
Cheap
