Review

The purpose of this review is to check for understanding. The page will indicate correct and incorrect answers as selections are clicked.


1) Select the statements that are true regarding Fibre Channel:


It is a serial interface that operates at 2 Gigabits per second.


Generally, the host server must be rebooted to recognize new devices.


It supports up to 16 million devices, in a switched fabric.


It supports both copper and fiber-optic cabling.


Termination is required on both ends of the cable.


Its fundamental elements are nodes, ports, and links.



2) Select the statements that are true regarding the Point to Point Fibre Channel topology:


Scalability is limited


Utilizes cascaded switches to assign bandwidth to each device


Is similar to the token-ring network topology


Generally the easiest Fibre Channel topology to configure


Devices communicate by sending a signal called the primitive back and forth.


Fibre Channel DPEs and DAEs incorporate this topology.



3) Select the statements that are true regarding the Arbitrated Loop topology:


A device in this topology has 100 percent of the bandwidth, all of the time.


The Arbitrated Loop topology is self-discovering.


In the Dell PowerVault series, a Port Bypass Circuit (PBC) is used in the backplane to detect the presence of an active disk node on each available port.


Theoretically, an arbitrated loop can support up to 16 million devices.


This is the least scalable of the three topologies.


Attaching an Arbitrated Loop to an FL_Port on a switch creates a public loop.



4) Select the statements that are true regarding the Switched Fabric Fibre Channel topology:


Each switch port is assigned an 8-bit address.


It supports self-discovery and self-configuration.


Universal ports on FC switches can operate as F_Ports, FL_Ports, or E_Ports.


A fabric can support a theoretical limit of 32 million nodes.



5) An HBA's execution throttle performs which function?


It determines the maximum data flow rate going to and from the server.


Permits/denies remote access to the server from across a network.


It specifies the maximum number of commands executing on any one port.


Manages access to up to three attached storage devices.



6) Based on cable nomenclature, a cable marked "100-SM-LL-L" would have which of the following sets of characteristics?


100 MB per second, static mode, load-balancing, long distance cable


100 MB per second, single mode, long-wave laser, long distance cable


100 MB per second, server mode, low-density laser, long distance cable


100 MB per second, switch mode, local-host, long distance cable



7) Which of the following statements are true regarding World Wide Names?


A WWN consists of an eight-byte hexadecimal number with each byte separated by a colon.


A WWN is taken directly from the device's MAC address.


World Wide Names are applied only to a SAN's storage devices; servers and switches do not use WWNs.


A WWN is hard-coded into a device; it cannot be changed or altered and must be used "as is".



8) Which statements are true regarding LUNs and LUN masking?


LUNs can be exclusively assigned to and accessed by a specific list of hosts.


LUNs are aliases assigned to single physical disks.


LUNs can also be used in part of the fail-over process when a component in the storage path fails.


LUN masking on the server level requires a software package to be installed on each server.



9) Clustering provides all of the following except:


Fault tolerance


Parallel processing


Load Balancing


Event Monitoring



10) Which component allows a SCSI tape drive to connect a Fibre Channel SAN environment?


Switch


Bridge


HBA


GBIC
