Namuhla sizofingqa ukuqeqeshwa kwethu futhi sibheke lokho esizokufunda ochungechungeni olusele lwezifundo zevidiyo. Njengoba sisebenzisa izinto zokuqeqesha zeCisco, sizovakashela iwebhusayithi yenkampani etholakala kuyo ukubona ukuthi sifunde kangakanani nokuthi singakanani esisele ukuze siqedele izifundo.
Inothi lomhumushi: selokhu kwashicilelwa le vidiyo ngoNovemba 28.11.2015, 13.04.2019, kube nezinguquko ekwakhiweni kwewebhusayithi ye-Cisco kanye nokuqukethwe izivivinyo, ngakho-ke izithombe-skrini ezilandelayo zibonisa isayithi kusukela ngomhlaka-XNUMX Ephreli XNUMX, futhi izinguquko zamanje kwenziwe kumbhalo wenkulumo.
Ukuze ubuke izinto zesifundo, chofoza isixhumanisi Sendawo Yokufunda bese uya ekhasini elithi Ukuqeqeshwa Nezehlakalo.
Okulandelayo, ekhasini Lokuqeqeshwa Nezehlakalo, kumenyu engakwesokudla, khetha isixhumanisi se-Cisco Certification.
Ekhasini lesitifiketi se-Cisco ungathola zonke izitifiketi ze-Cisco eziqoqwe ngeleveli yobungcweti: Ukungena, Hlangana, Uchwepheshe, Ingcweti, kanye Nomakhi.
Isitifiketi se-CCNA silingana nezinga eliyisisekelo lesitifiketi Esihlotshaniswayo, eliqinisekisa ulwazi oludingekayo ukuze ufake, ulungiselele, futhi uphathe amanethiwekhi wendawo anosayizi omaphakathi nendawo ebanzi.
Izinga Lokungena lihlanganisa izitifiketi ze-CCENT (Cisco Certified Entry Networking Technician) kanye ne-CCT (Technician). Uma uchofoza ku-CCENT, uzoyiswa ekhasini elinemininingwane yesitifiketi futhi elisho ukuthi azikho izimfuneko zokusithola. Ukuze uthole isitifiketi esinjalo, kufanele uphumelele ukuhlolwa 100-105 ICND1. Izinga Le-Associated liqukethe okukhethekile okuhlukahlukene, futhi amazinga Ochwepheshe, Uchwepheshe kanye Ne-Architect aqanjwa ngendlela efanayo.
Uma sikhuluma ngesitifiketi se-CCNA, sisho ukuthi simelela okukhethekile emkhakheni womzila kanye nokuxhumana kwenethiwekhi - I-CCNA Routing & Switching. Kuyacaca ukuthi uchwepheshe onesitifiketi esinjalo uzobhekana nama-Cisco routers kanye nokushintsha. Lona ubuchwepheshe obujwayelekile kakhulu obunikezwa yi-Cisco.
Uma ubheka isitifiketi se-CCNA Security Network Security Specialist, uzothola ukuthi umbandela wokusithola ukuthi ube nesitifiketi esivumelekile se-CCENT, i-CCNA Routing & Switching, nanoma yisiphi isitifiketi se-CCIE. Kungase kuqashelwe ukuthi isitifiketi se-CCNA R&S siyisisekelo sokuthola ezinye izitifiketi eziningi ezikhethekile.
Isimo siyefana ekutholeni izitifiketi zezinga lobungcweti: uma udinga i-CCNP R&S, kufanele ube nesitifiketi se-CCNA R&S. Ngokunjalo, ukuze uthole Ukuvikeleka kwe-CCNP, kufanele ube ne-CCNA Security.
Ngaphambilini, ukuze uthole isitifiketi se-CCNA R&S bekufanele uphumelele ukuhlolwa oku-1 kuphela, kodwa eminyakeni embalwa edlule uCisco wenze izinguquko. Abantu abanokuqeqeshwa kwangaphambili bangaqhubeka nokuthatha ukuhlolwa kwe-CCNA okukodwa kwe-200-125, kodwa uma ungenalo isizinda sobuchwepheshe, ungazama ukuthatha izivivinyo ezi-2: 100-105 ICND1, okuyisivivinyo esifanayo esithathwe isitifiketi se-CCENT, kanye nokuhlolwa okungu-200. -105 ICND2. Ngokuphumelela zombili lezi zivivinyo, ungathola isitifiketi se-CCNA.
Njengoba sesishilo, azikho izinto ezidingekayo ukuze uphumelele lezi zivivinyo, okungukuthi, ukuthola isitifiketi. Ukuhlolwa okukodwa kufushanisiwe njenge-CCNAX, noma “kusheshisiwe.” Ungase ufune ukubuza mayelana nezindleko zezitifiketi: I-Cisco CCNA ibiza u-$295 uma uthatha ukuhlolwa okukodwa kwe-200-125 CCNA. Ukuhlolwa ngakunye kwezinye ezimbili kuzokubiza u-$150. Ngakho-ke, uma uthatha izivivinyo ezi-2, ukhokha i-$5 eyengeziwe ngenxa yokuthi kulula ukudlula ukuhlolwa okukodwa. Ukhetha indlela engcono kakhulu yokuphasa izivivinyo. Ngingaluleka ngokuthatha izivivinyo ezi-2 ngokulandelana.
Ake sibone ukuthi ukuhlolwa kwe-100-105 ICND1 kuyini ngokuchofoza futhi ukuya ekhasini lencazelo. Kunamathebhu amane: Uhlolojikelele Lwesivivinyo, Ukulungiselela Ukuhlolwa, Ukwenza Ukuhlolwa, kanye Nezinqubomgomo Zokuhlolwa. Ukuze wenze izivivinyo, kufanele ubhalise kwaPearson VUE.
Uma uchofoza inkinobho ethi Bhalisa ku-Pearson VU, uzoyiswa ku-home.pearsonvue.com/cisco futhi uzobona izinkinobho zokuthi Ngena Ngemvume futhi Udale I-akhawunti kwesokudla sekhasi. Uma usubhalisa esizeni, ufaka inombolo yokuhlolwa engu-100-105 efomini lokusesha, bese usesha usuku olufanele, isikhungo seCisco esiseduze nawe, ubhalisele ukuhlolwa bese ungenza inkokhelo ye-inthanethi. Ukuze uthole isikhungo sokuhlola esiseduze, uchofoza isixhumanisi esithi Thola isikhungo sokuhlola bese ufaka ikheli lakho kubha yokusesha.
Izikhungo zokuhlola iCisco zitholakala yonke indawo, futhi angazi ngisho nedolobhana elincane elingenaso okungenani isikhungo esisodwa esinjalo. Kungenzeka ukuthi zikhona izindawo ezinjena, kodwa ngokwami angikaze ngiyibone efana nalena.
Ake sifune idolobha laseCoventry ngoba ngafunda eCoventry, eWest Midlands, eNgilandi. Leli idolobhana elincane kakhulu, kodwa njengoba ubona, kunesikhungo esinjalo esi-1 e-Coventry ngokwayo kanye nezinye ezi-4 ezitholakala ebangeni lamamayela ayi-16-17. Uma uchofoza inkinobho ethi 'Bonisa ezinye izikhungo zokuhlola' uzobona ezinye izindawo ezimbalwa ezikude kakhulu ne-Coventry, njenge-Birmingham. Ngemva kokukhetha isikhungo, uya lapho ukuze uyobhala izivivinyo.
Ukuhlolwa kuqukethe imibuzo yokukhetha eminingi engama-45-55, imvamisa emine, okumele iphendulwe kungakapheli imizuzu engama-90. Kulula impela, ukuhlolwa kuqhutshwa kumakhompyutha, okuwukuphela kwento oyidingayo ukuzijayeza kahle ukuxazulula izinkinga ezinjalo ngaphambi kokuthatha isivivinyo, ngoba isikhathi sokuphasa sinqunyelwe. Awunikezwa imizuzu engaphezu kwemi-2 yempendulo ngayinye, ngakho-ke akufanele “uhlale” phezu kombuzo owodwa isikhathi eside - uma ungayazi impendulo, dlulela kolandelayo.
Ake sibheke izihloko zemibuzo yokuhlolwa kwesifundo se-ISND1 ngokuchofoza inkinobho yezihloko ze-Exam.
(inothi lomhumushi: esikhundleni sesibonelo sokuhlolwa okuphelelwe yisikhathi 100-101, umbhali wenkulumo abhekisela kuyo, izithombe-skrini zibonisa inguqulo entsha yokuhlolwa kwe-100-105 enezichibiyelo ezifanele embhalweni wesifundo).
Ubona izigaba zezihloko zokuhlolwa kwe-ICND1, futhi uma ngiqeda isifundo sevidiyo ngezihloko zalolu hlolo, ngizodlulela ezihlokweni zokuhlolwa kwe-ICND2, futhi ngemva kwezifundo zevidiyo ezingu-50 noma ezingu-60, uzobe ususifunde ngokuphelele konke. izihloko zezifundo ze-CCNA. Ungabuyekeza imibuzo esihlokweni sokuqala, “Izisekelo Zenethiwekhi,” ngokuningiliziwe ngokuchofoza isixhumanisi esithi Bonisa Imininingwane.
Lokhu ukuqhathanisa kanye nomehluko phakathi kwamamodeli we-OSI kanye ne-TCP/IP, izivumelwano ze-TCP ne-UDP, incazelo yezingxenye zengqalasizinda yenethiwekhi esebenzayo, ukuqhathanisa kanye nomehluko phakathi kwama-topology enethiwekhi, nokunye - sihlanganise zonke lezi zihloko esikhathini esidlule. izifundo.
Okulandelayo kuza isihloko esithi “LAN Switching Fundamentals”, esithatha ama-26% esifundo. Ihlanganisa incazelo nencazelo yomqondo wokuxhumana, incazelo yefomethi yohlaka lwe-Ethernet, nokunye okuningi esikuxoxile. Uma ngingakakhulumi ngokuthile, ngizobuyela kule mibuzo. Ngakho-ke uma ubheka lezi zihloko, uzobona ukuthi yiziphi esesike sazihlanganisa nokuthi yiziphi esingakazikhulumi. Sizoxoxa ngezinye zezinkinga ezihlobene nokusingathwa kwe-IP maduze, futhi sizobuyela engxoxweni enemininingwane ye-IPv6. Siphinde sahlanganisa ukuphepha kwedivayisi yenethiwekhi, i-VLAN yomdabu, imodi enamathelayo, imikhawulo yekheli le-MAC, nokunye.
Ngesifundo sevidiyo esilandelayo, sizoqala ukufunda izisekelo Zezisekelo Zomzila.
Ungaphrinta uhlu lwezihloko bese umaka lezo esezivele siziqedile. Njengoba siqhubeka nesifundo, sizohlola lolu hlu ukuze siqinisekise ukuthi siyazi ukuthi sihlanganise ini kanye nalokho okusadingeka sikuhlanganise. Ukuze ulungiselele ukuhlolwa, kufanele ufunde yonke le mibuzo ngesihloko ngesihloko.
Ngakho-ke, sesiqedile ukufunda amaswishi futhi sabheka kancane ukusebenza kwama-routers. Ngizokhuluma okwengeziwe ngezinkinga zokushintshwa, futhi ngithemba ukuthi ngemva kwesifundo sevidiyo esingama-30 uzobe usulungele ukwenza ukuhlolwa kwe-ICND1. Ngicabanga ukuthi sizoqeda ngokuphelele ukulungiswa kuvidiyo 31,32, 33 noma XNUMX bese sibona ukuthi usukulungele yini lolu hlolo. Kuwebhusayithi yami ngizothumela imisebenzi ephathekayo ongayiqedela.
Uma sesiqedile ngakho konke lokhu, uzokwazi ukubhalisa kwa-Pearson VUE futhi uthathe isivivinyo se-100-105 ICND1. Ngemva kwalokho sizobuyela ezifundweni zevidiyo futhi futhi siqale ukufunda imibuzo yokuhlolwa kwesifundo se-ICND200 105-2.
Sizoqala ngokubheka ubuchwepheshe bokushintsha i-LAN, lapho sizobheka ukuthi amaphrothokholi e-STP asebenza kanjani, bese siqhubekela kubuchwepheshe bomzila futhi sibheke izinguqulo ezihlukene zephrothokholi ye-OSPF, njalonjalo.
Ungavakashela iwebhusayithi eshiwo futhi uqiniseke ukuthi konke kulula futhi kulula. Okokuqala, ngizokucela ukuthi uzame ukuthatha amanothi abhalwe ngesandla ngenkathi ubuka izifundo zami zevidiyo, ezizokusiza kakhulu. Okwesibili, udinga ukwenza izabelo zokuzijwayeza, thayipha imiyalo kukhompuyutha ephathekayo yakho, usebenzisa i-Cisco Packet Tracer noma i-GNS3 noma amadivaysi aphathekayo uma kungenzeka. Kufanele uzijwayeze ukusebenzisa imiyalo ukuze uzenzele eyakho inethiwekhi ngoba ngaphandle kokuzijwayeza ngeke ulungele ukwenza izivivinyo zeCisco.
Ngakho yilo lonke ulwazi engangifuna ukulidlulisela. Zizwe ukhululekile ukungibuza imibuzo nge-imeyili noma kumazwana angezansi kwale vidiyo.
Siyabonga ngokuhlala nathi. Uyazithanda izindatshana zethu? Ufuna ukubona okuqukethwe okuthakaselayo okwengeziwe? Sisekele ngokufaka i-oda noma ngokuncoma kubangani, Isaphulelo sika-30% sabasebenzisi be-Habr ku-analogue ehlukile yamaseva eleveli yokungena, esungulwe yithi ngenxa yakho: (itholakala nge-RAID1 kanye ne-RAID10, kufika kuma-cores angu-24 kuze kufike ku-40GB DDR4).
