What advantages do WPARs have over LPARs？（）

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 . forward an admission request to the local gatekeeper B . forward an admission request to the remote gatekeeper C . send a location request to the remote gateway D . send a location request to the remote gatekeeper

A . decreasing the number of collision domains B . filtering frames based on MAC addresses C . allowing simultaneous frame transmissions D . increasing the size of broadcast domains E . increasing the maximum length of UTP cabling between device

A . VLANs establish broadcast domains in switched networks. B . VLANs utilize packet filtering to enhance network security. C . VLANs provide a method of conserving IP addresses in large networks. D . VLANs provide a low-latency internet working alternative to routed networks. E . VLANs allow access to network services based on department, not physical location. F . VLANs can greatly simplify adding, moving, or changing hosts on the network.

A . The message can be directed to the desired location B . The message can follow the earth‟s curvature C . The quality of message can not be affected by climatic D . the range of the message extend and the quality of reception is improved

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 . decreasing the number of collision domains B . filtering frames based on MAC addresses C . allowing simultaneous frame transmissions D . increasing the size of broadcast domains E . increasing the maximum length of UTP cabling between device

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 . On the desired WPAR：mkrole authorizations=aix.wpar.system newRole setkst -t role chuser roles=newRole default_roles=newRole user1 B . On the global environment：mkrole authorizations=aix.wpar.system newRole setkst -t role chuser roles=newRole default_roles=newRole user1 C . On the desired WPAR：Edit the /etc/security/authorizations file adding：‘newRole authorizations=aix.wpar.system’setkst -t role chuser roles=newRole default_roles=newRole user1 D . On the global environment：Edit the /etc/security/authorizations file adding：‘newRole authorizations=aix.wpar.system’setkst -t role chuser roles=newRole default_roles=newRole user1

A . They are less expensive B . They are smaller for equivalent pumping ability C . They pump more cargo in less time D . All of the above

A . WPARs give more controls for resource management than the traditional AIX operating system tools. B . WPARs support Live Application Mobility which can be used to balance user processes acrosssystems. C . WPARs each have a copy of the AIX kernel， offering better availability than a system without WPARs. D . WPARs provide the ability to apply fixes specific for each environment， enabling the customer to create specialized application servers.
