An advantage of an ABC dry chemical over a carbon dioxide extinguisher is（）.

A .  lower cost B .  higher chirp C .  easier to manufacture D .  higher dispersion tolerance E .  higher optical signal-to-noise ratio

A . QuickVPN (QVPN) client software for simplified management B . minimal configuration requirements C . 802.1g capabilities and support for multiple wireless networks simultaneously (multiple BSSIDs) D . wireless bridging to overcome the lack of physical network cable

A . It is effective in controlling fire in flowing oil such as coming from a broken fuel line B . It absorbs heat from materials that could cause reignition C . Most foams can be used jointly with dry chemical extinguishing agents to attack a fire by two methods of extinguishment D . Once the surface is blanketed with foam and the fire is extinguished，no further foam is required

A . greater range B . effectiveness on all types of fires C . cleanliness D . All of the above

A . SVC supports more RAID levels than HP EVA B . SVC has a broader worldwide installation base than HP EVA C . SVC provides SAN virtualization within the storage area network D . SVC is an IBM virtualization solution for IBM disks in an HP EVA

A . are less expensive B . require less maintenance C . can be started across the line D . offer a more effective means of controlling speed

A . can be used in conjunction with wire or spring-lay rope B . can be stored on decks exposed to sunlight C . can hold a load even when a considerable amount of the yarns have been abraded D . gives audible warning of overstress whereas manila does not

A . Electrically non-conductive B . Relatively inexpensive C . Effective against chemicals containing an oxidizer D . All of the above

A .  It supports admission control that allows a network to reject or downgrade new RSVP sessions if one of the interfaces in the path has reached the limit （that is， all reservable bandwidth is booked）. B .  RSVP signals QoS requests per individual flow. In the request the authorized user （authorization object） and needed traffic policy （policy object） are sent. The network can then provide best-effort delivery to these individual flows. C .  RSVP streamlines communication by making it unnecessary to inform network devices of flow parameters （IP addresses and port numbers）. D .  Because of the stateful RSVP architecture， continuous signaling does not have to occur. E .  The flow-based approach is scalable to large implementations， such as the public Internet， because RSVP tracks each individual flow.

A . greater range B . effective on all types of fires C . cleanliness D . All of the above

A . greater high temperature strength B . better heat conductivity C . greater weight per cubic inch D . increased resistance to wear

A . Less fuel consumption per SHP B . Diesel fuel costs less than bunker C or its equivalent C . Less routine maintenance required D . Less weight per SHP

A . a mattress B . spilled liquids such as oil or paint C . high voltage electrical gear D . a trash ca

A . Reduced power and space requirements B . Saves money on software costs C . Maintenance is easier because there is only one server D . Fewer instances of the operating system to maintai

A . Large misalignments can be tolerated between the shaft and engine coupling B . Slip is held to a minimum when reversing shaft rotation C . Engine torsion vibrations to the driven shaft are eliminated D . It aids in maintaining power factor

A . a mattress B . spilled liquids such as oil or paint C . high voltage electrical gear D . a trash ca

A．Limited liability B．Avoiding double taxation C．Easier access to stock market D．Less-rigid profit allocation
