12.describe the difference between dynamic arp table entries & static arp table entries.​: an arp table can contain 2 types of entries: dynamic & static.Dynamic arp table entries R created when a client makes an arp request that could not be satisfied by data already in the arp table.Static arp table entries R those that some1 hs entered manually using the arp utility.

13.describe the differences between a brownout & a blackout.​: a brownout is a ​momentary decrease in voltage;also known as a sag.An overtaxed electrical system can cause brownouts,which U might recognize in yur home as a dimming of the lights.Such voltage decreases can cause computers or applications 2 fail & potentially corrupt data.A blackout is a complete power loss.A blackout could cause significant damage 2 yur ne2rk.4 example,if a server loses power while files R open & processes R running,its nos might be damaged so extensively that the server cannot restart & the nos must be reinstalled from scratch.A backup power source,however,can provide power long enough 4 the server 2 shut down properly & avoid harm.

14.describe the ospf routing protocol.​: ospf (open shortest path 1st) is an igp & a link-state routing protocol used on interior or border routers.It was introduced as an improvement 2 rip & can coexist with rip (or ripv2) on a ne2rk.Unlike rip,ospf imposes no hop limits on a transmission path.Also,ospf uses a more complex algorithm 4 determining best paths than what rip uses.Under optimal ne2rk conditions,the best path is the most direct path between 2 points.If excessive traffic levels or an outage preclude data from following the most direct path,a router may determine that the most efficient path actually goes through additional routers.Each router running ospf maintains a database of the other routers' links.If ospf learns of the failure of a given link,the router can rapidly compute an alternate path.This calculation demands more memory & cpu power than rip would,but it keeps ne2rk bandwidth 2 a minimum & provides a very fast convergence time,often invisible 2 users.The algorithms used by link-state protocols & their faster convergence time also prevent routing loops.Ospf is supported by all modern routers.Therefore,it is commonly used on autonomous systems that rely on a mix of routers from different manufacturers.

15.describe the 3 different types of cabling recognized by tia/eia as acceptable 4 horizontal wiring.​: tia/eia recognizes 3 possible cabling types 4 horizontal wiring: utp,stp,or fiber optic cable.Utp (unshielded twisted pair) cable is a type of copper-based cable that consists of 1 or more insulated twisted-wire pairs encased in a plastic sheath.Stp (shielded twisted pair) cable is a type of copper-based cable containing twisted-wire pairs that R not only individually insulated,but also surrounded by a shielding made of a metallic substance such as foil.Fiber-optic cable is a form of cable that contains 1 or several glass or plastic fibers in its core & comes in 2 types: single-mode fiber (smf) or multimode fiber (mmf).Copper-based cable transmits data via electric signals,& fiber-optic cable transmits data via pulsing light sent from a laser or light-emitting diode (led).

16.a device that changes the form of electrical energy in some way.4 common types R inverter,rectifier,
transformer,& voltage regulator.: power converter​

17.a device that converts dc electrical energy 2 ac electrical energy.Btr inverters will also condition the power,which helps protect sensitive electronic equipment from power fluctuations.​: inverter​

18.a device that maintains a constant voltage level 4 either ac or dc electrical energy.: voltage regulator

19.dnat (dynamic ne2rk address translation): the gateway assigns ip address from a pool 2 host

20.dns follows a centralized database model: false

21.​during termination of twisted pair cabling,what should be d1 2 ensure minimal cross talk is introduced?: no more than 1 inch of the cable should be exposed.

22.each organization that provides host services on the public internet is responsible 4 providing & maintaining dns authoritative servers 4 public access: tru

24.electrical power flow on a circuit that continually switches direction.: alternating current (ac)​

25.equipment racks most commonly come in what 2 widths?​: 19 & 23 inch frame

26.ethernet exists @ what layer of the osi model?​: layer 2

27.explain how equipment should be configured in a rack 2 best optimize airflow & temperature.​: hardware should be installed as close 2 the front of the rack as possible 2 allow 4 proper airflow in the back.Minimizing cable clutter can also help prevent airflow blockages.In a typical rack system,airflow through the chassis is typically designed 2 move from front 2 back.Rack-monitoring systems should be installed 2 sound an alarm if the rack' s overall temperature rises too much,if air quality (moisture or smoke) falls below acceptable levels,or if airflow is restricted.Because rack security is also a concern,these monitoring systems can alert technicians when a door is lft open,or use motion sensors 2 detect the presence of an intruder.In data rooms containing multiple rows of racks,a hot aisle/cold aisle layout,pulls QL air from vents in the floor or from nearby,low-lying wall vents into the rows of racks.The hot air aisles R used 2 direct the heated air away from the racks into exhaust vents 4 cooling.
