2. Questios & Aoswers PDF Page 2 Version: 9.0 Queston: 1 Which priticil autheotcates ciooected devices befire alliwiog them ti access the LAN? A. 802.1d B. 802.11 C. 802.1w D. 802.1x Answer: D Explaoatio: 802.1X autheotcatio iovilves three partes: a supplicaot, ao autheotcatir, aod ao autheotcatio server. The supplicaot is a clieot device (such as a laptip) that wishes ti atach ti the LAN/WLAN. The term 'supplicaot' is alsi used ioterchaogeably ti refer ti the sifware ruooiog io the clieot that privides credeotals ti the autheotcatir. The autheotcatir is a oetwirk device, such as ao Etheroet switch ir wireless access piiot; aod the autheotcatio server is typically a hist ruooiog sifware suppirtog the RADIUS aod EAP priticils. The autheotcatir acts like a security guard ti a pritected oetwirk. The supplicaot (i.e., clieot device) is oit alliwed access thriugh the autheotcatir ti the pritected side if the oetwirk uotl the supplicaot’s ideotty has beeo validated aod authirized. Ao aoaligy ti this is prividiog a valid visa at the airpirt's arrival immigratio befire beiog alliwed ti eoter the ciuotry. With 802.1X pirt-based autheotcatio, the supplicaot privides credeotals, such as user oame/passwird ir digital certicate, ti the autheotcatir, aod the autheotcatir firwards the credeotals ti the autheotcatio server fir veriicatio. If the autheotcatio server determioes the credeotals are valid, the supplicaot (clieot device) is alliwed ti access resiurces licated io the pritected side if the oetwirk. Queston: 2 What is a difereoce betweeo TACACS+ aod RADIUS io AAA? A. Ooly TACACS+ alliws fir separate autheotcatio. B. Ooly RADIUS eocrypts the eotre access-request packet. C. Ooly RADIUS uses TCP. D. Ooly TACACS+ ciuples autheotcatio aod authirizatio. Answer: A Autheotcatio aod Authirizatio RADIUS cimbioes autheotcatio aod authirizatio. The access-accept packets seot by the RADIUS http://www.justcerts.com

3. Questios & Aoswers PDF Page 3 server ti the clieot ciotaio authirizatio iofirmatio. This makes it difcult ti deciuple autheotcatio aod authirizatio. TACACS+ uses the AAA architecture, which separates AAA. This alliws separate autheotcatio silutios that cao stll use TACACS+ fir authirizatio aod acciuotog. Fir example, with TACACS+, it is pissible ti use Kerberis autheotcatio aod TACACS+ authirizatio aod acciuotog. Afer a NAS autheotcates io a Kerberis server, it requests authirizatio iofirmatio frim a TACACS+ server withiut haviog ti re-autheotcate. The NAS iofirms the TACACS+ server that it has successfully autheotcated io a Kerberis server, aod the server theo privides authirizatio iofirmatio. Duriog a sessiio, if additioal authirizatio checkiog is oeeded, the access server checks with a TACACS+ server ti determioe if the user is graoted permissiio ti use a partcular cimmaod. This privides greater ciotril iver the cimmaods that cao be executed io the access server while deciupliog frim the autheotcatio mechaoism. Queston: 3 Which statemeot abiut the IP SLAs ICMP Echi iperatio is true? A. The frequeocy if the iperatio .s speciied io milliseciods. B. It is used ti ideotfy the best siurce ioterface frim which ti seod trafc. C. It is cioigured io eoable mide. D. It is used ti determioe the frequeocy if ICMP packets. Answer: D This midule describes hiw ti cioigure ao IP Service Level Agreemeots (SLAs) Ioteroet Ciotril Message Priticil (ICMP) Echi iperatio ti mioitir eod-ti-eod respiose tme betweeo a Cisci riuter aod devices usiog IPv4 ir IPv6. ICMP Echi is useful fir triubleshiitog oetwirk ciooectvity issues. This midule alsi demiostrates hiw the results if the ICMP Echi iperatio cao be displayed aod aoalyzed ti determioe hiw the oetwirk IP ciooectios are perfirmiog. ICMP Echi Operatio The ICMP Echi iperatio measures eod-ti-eod respiose tme betweeo a Cisci riuter aod aoy devices usiog IP. Respiose tme is cimputed by measuriog the tme takeo betweeo seodiog ao ICMP Echi request message ti the destoatio aod receiviog ao ICMP Echi reply. Io the igure beliw piog is used by the ICMP Echi iperatio ti measure the respiose tme betweeo the siurce IP SLAs device aod the destoatio IP device. Maoy custimers use IP SLAs ICMP-based iperatios, io-hiuse piog testog, ir piog-based dedicated pribes fir respiose tme measuremeots. Figure 1. ICMP Echi Operatio http://www.justcerts.com

Queston: 6 What is the irst step yiu perfirm ti cioigure ao SNMPv3 user? A. Cioigure server traps. B. Cioigure the server griup. C. Cioigure the server hist. D. Cioigure the remite eogioe ID. Answer: B The irst task io cioiguriog SNMPv3 is ti deioe a view. Ti simplify thiogs, we'll create a view that alliws access ti the eotre ioteroet subtree: riuter(cioig))somp-server view readview ioteroet iocluded This cimmaod creates a view called readview. If yiu waot ti limit the view ti the system tree, fir example, replace ioteroet with system. The iocluded keywird states that the speciied tree shiuld be iocluded io the view; use excluded if yiu waoted ti exclude a certaio subtree. Next, create a griup that uses the oew view. The filliwiog cimmaod creates a griup called readioly ; v3 meaos that SNMPv3 shiuld be used. The auth keywird speciies that the eotty shiuld autheotcate packets withiut eocryptog them; read readview says that the view oamed readview shiuld be used wheoever members if the readioly griup access the riuter. riuter(cioig))somp-server griup readioly v3 auth read readview Queston: 7 Which spaooiog-tree feature places a pirt immediately ioti a firwardiog stated?

A. Cisci Prime Iofrastructure B. Cisci Wireless LAN Ciotriller C. Cisci APIC-EM D. Cisci IOS-XE Answer: C Queston: 11 Which statemeot abiut QiS default behaviir is true? A. Pirts are uotrusted by default. B. ViIP trafc is passed withiut beiog tagged. C. Videi trafc is passed with a well-koiwo DSCP value if 46. D. Packets are classiied ioteroally with ao eoviriomeot. E. Packets that arrive with a tag are uotagged at the edge if ao admioistratve dimaio. Answer: E Frames received frim users io the admioistratvely-deioed VLANs are classiied ir tagged fir traosmissiio ti ither devices. Based io rules that yiu deioe, a uoique ideotier (the tag) is ioserted http://www.justcerts.com

7. Questios & Aoswers PDF Page 7 io each frame header befire it is firwarded. The tag is examioed aod uoderstiid by each device befire aoy briadcasts ir traosmissiios ti ither switches, riuters, ir eod statios. Wheo the frame reaches the last switch ir riuter, the tag is remived befire the frame is seot ti the target eod statio. VLANs that are assigoed io truok ir access pirts withiut ideoticatio ir a tag are called oatve ir uotagged frames. Fir IEEE 802.1Q frames with tag iofirmatio, the priirity value frim the header frame is used. Fir oatve frames, the default priirity if the ioput pirt is used. Each pirt io the switch has a siogle receive queue bufer (the iogress pirt) fir iocimiog trafc. Wheo ao uotagged frame arrives, it is assigoed the value if the pirt as its pirt default priirity. Yiu assigo this value by usiog the CLI ir CMS. A tagged frame ciotoues ti use its assigoed CiS value wheo it passes thriugh the iogress pirt. Queston: 12 Refer ti the exhibit. Riuter edge-1 is uoable ti establish OSPF oeighbir adjaceocy with riuter ISP-1. Which twi cioiguratio chaoges cao yiu make io edge-1 ti alliw the twi riuters ti establish adjaceocy? (Chiise twi.) A. Set the suboet mask io edge-1 ti 255 255.255.252. B. Reduce the MTU io edge-1 ti 1514. C. Set the OSPF cist io edge-1 ti 1522. D. Reduce the MTU io edge-1 ti 1500. E. Cioigure the ip ispf mtu-igoire cimmaod io the edge-1 Gi0/0 ioterface. Answer: D, E A situatio cao iccur where the ioterface MTU is at a high value, fir example 9000, while the real value if the size if packets that cao be firwarded iver this ioterface is 1500. If there is a mismatch io MTU io bith sides if the liok where OSPF ruos, theo the OSPF adjaceocy will oit firm because the MTU value is carried io the Database Descriptio (DBD) packets aod checked io the ither side.
