QUESTION: 1A making company is actually building a fresh plant. The apparatus within the grow offers beenknown to bring about interference using the network at alternative sites and they will want to be sure thatthey decide a mass media that's resistant to be able to electro-mechanical interference. Which form of cable tv shouldthey use?

A. Thick coaxial cableB. Fiber optic cableC. Unshielded twisted pairD. Plenum twisted pair

Answer: B

QUESTION: 2A office was transferred from one floor to another. When the division appeared to be within the oldfloor, this end users connected by way of a combination of 10 Mb hubs plus 10/100 Mb switches.When the particular department appeared to be relocated each of the hubs were supplanted by way of 10/100 Mb switches.Two connected with the actual clients are generally reporting that the multi-level is usually a great deal weaker for the different level eventhough the actual hubs were being replaced. You see that that move plug-ins these types of consumers hook up towere familiar with connect to the actual hubs and are by hand set up to get 10Mb half-duplex. ThePCs have been powering the particular swap along with were physically configured with regard to 100 Mb full-duplex.What has been performed in avoiding this kind of issue?

A. Auto-negotiation exclusively was required to always be enabled for the switch.B. Auto-negotiation needs been enabled to the switch ports and to the PCs.C. Auto-sensing merely necessary to possibly be made it possible for about the switch.D. Auto-sensing requires already been made it possible for with that button ports plus about the PCs.

Answer: B

QUESTION: 3A firm features thought we would lower your expenses and buy remanufactured IP telephones. Theypurchased Phase a single (One) IP telephones of which will not assist Power-over-Ethernet (PoE).The Ethernet Switches some people purchased do source PoE for each the IEEE 802.3afspecifications. Which statement about the particular Phase 1 IP phones is actually true?

A. They have to be plugged into AC energy sites to function.B. They may use an electrical splitter for you to be given each strength and data from this EthernetSwitch. 920-805

C. They can use a power splitter for you to receive both electric power in addition to info from your EthernetSwitch, but must be mounted on a good AC shop for you to boot and acquire a strong IP address.D. They needs to be plowed into AC electricity stores on top of that in addition to acquire a great IP address.Afterthe phone number is operating, it could function over Ethernet Switch only.

Answer: B

QUESTION: 4Which order can be correct regarding these kind of elements inside the Ethernet frame?

A. Destination MAC address, origin MAC address, length/type field, data, FCSB. Destination MAC address, reference MAC address, data, length/type field, FCSC. Source MAC address, destination MAC address, length/type field, data, FCSD. Source MAC address, vacation spot MAC address, data, length/type field, FCS

Answer: A

QUESTION: 5Which statement related to put out domains and accident names will be false?

A. When to connect is Ethernet full-duplex, the collision website only features twodevices.B. When your association is actually Ethernet full-duplex, that send out sector merely contains twodevices.C. When your link is used for you to connect devices, just about all ports are in similar impact website butnot in the same over the air domain.D. When a button having numerous VLANs is required for connecting devices, just about all jacks have been in thesame broadcast domain.

Answer: B

QUESTION: 6Which perform do Route policies to the Ethernet Routing Switch (ERS) perform?

A. Route insurance policies could get rid of as well as obvious the IP routing table.B. OSPF redistribute function is used to help pass on OSPF routes the next single area.C. RIP announce plans determine the way RIP acquired passages are generally symbolized inside therouting table.D. BGP redistribute functionality can be utilized that will market OSPF learned paths applying BGP.

QUESTION: 1A making firm will be constructing a brand new plant. The gear in the place has beenknown that will cause interference with all the community at different web pages along with they desire to be certain thatthey choose a media that may be resistant to power interference. Which method of cable shouldthey use?

A. Thick coaxial cableB. Fiber optic cableC. Unshielded twisted pairD. Plenum twisted pair

Answer: B

QUESTION: 2A department seemed to be relocated from just one floor that will another. When the particular office seemed to be for the oldfloor, the actual users connected through a mixture of 10 Mb hubs plus 10/100 Mb switches.When the actual team has been shifted all the hubs have been supplanted through 10/100 Mb switches.Two with the end users will be reporting which the network will be significantly slow within the brand-new terrain eventhough the particular hubs were replaced. You learn how the swap vents most of these consumers connect towere helpful to connect to the actual hubs and so are manually set up for 10Mb half-duplex. ThePCs were being associated with this change and also have been manually configured for one hundred Mb full-duplex.What has been completed in avoiding that issue?

A. Auto-negotiation simply were required to be empowered on the particular switch.B. Auto-negotiation need to have got recently been made it possible for on the move ports in addition to for the PCs.C. Auto-sensing solely needed to become allowed on the actual switch.D. Auto-sensing needs happen to be allowed for the transition vents and also within the PCs.

Answer: B

QUESTION: 3A company features thought to get a better price and get remanufactured IP telephones. Theypurchased Phase 1 (One) IP telephones which don't help support Power-over-Ethernet (PoE).The Ethernet Switches they purchased do offer PoE each the actual IEEE 802.3afspecifications. Which assertion about the Phase 1 IP telephones is definitely true?

A. They must be plugged directly into AC electric power stores for you to function.B. They can use an electrical splitter that will be given together electrical power along with facts from your EthernetSwitch. 920-805

C. They may use a power splitter to receive both electrical power in addition to files with the EthernetSwitch, but must also be attached with an AC wall socket to help boot and acquire an IP address.D. They should be plugged straight into AC electric power stores as well and also acquire a great IP address.Afterthe telephone is actually operating, it might work off of your Ethernet Switch only.

Answer: B

QUESTION: 4Which order can be correct for all these components while in the Ethernet frame?

A. Destination MAC address, supply MAC address, length/type field, data, FCSB. Destination MAC address, resource MAC address, data, length/type field, FCSC. Source MAC address, destination MAC address, length/type field, data, FCSD. Source MAC address, place MAC address, data, length/type field, FCS

Answer: A

QUESTION: 5Which record regarding transmit names and collision domain names is actually false?

A. When your link is Ethernet full-duplex, the collision area only contains twodevices.B. When to connect is Ethernet full-duplex, this send out space just contains twodevices.C. When a new center is employed in order to get in touch devices, all ports are developing the identical accident site butnot in the identical send out domain.D. When a button with numerous VLANs must be used for connecting devices, almost all ports come in thesame over the air domain.

Answer: B

QUESTION: 6Which function do Route policies for the Ethernet Routing Switch (ERS) perform?

A. Route guidelines can take out and very clear the actual IP routing table.B. OSPF redistribute function is required to pass on OSPF channels in just a individual area.C. RIP pronounce guidelines figure out how RIP realized tracks usually are showed in therouting table.D. BGP redistribute operate can be utilized to help publicise OSPF learned routes employing BGP.
