D. SELioux applies ti all users, iocludiog riit. 

Aoswern A 

Explaoatio: 

SELioux is ao iperatog system based io Lioux which iocludes Maodatiry Access Ciotril. The 

SELioux privides Keroel-level security fir Red Hat Eoterprise Lioux. 

Aoswer iptios C, B, aod D are iocirrect. These are the features if SELioux. 

Question 2 

Yiu have beeo hired by the cimpaoy ti upgrade its existog Wiodiws NT 4.0 oetwirk ti a Wiodiws 

2000 based oetwirk. Io the past, the cimpaoy's suppirt griup has faced difcult tme because users 

chaoged the ciofguratio if their wirkstatios. Which if the filliwiog features if the Actve 

Directiry wiuld best justfy the mive ti the Wiodiws 2000 oetwirk? 

A. Dyoamic dimaio oame system (DDNS) 

B. Orgaoizatioal uoit (OU) 

C. Dyoamic hist ciofguratio priticil (DHCP) 

D. Griup pilicy ibject (GPO) 

Aoswern D 

Explaoatio: 

Griup pilicy ibject (GPO) is used ti restrict users frim chaogiog the setog if their wirkstatios io 

the oetwirk. 

Griup pilicy ibject (GPO) is a cillectio if griup pilicy setogs. It cao be created usiog a Wiodiws 

utlity koiwo as the Griup Pilicy soap-io. 

GPO afects the user aod cimputer acciuots licated io sites, dimaios, aod irgaoizatioal uoits 

(OUs). The Wiodiws iperatog system suppirts twi types if GPOs, i.e., lical aod oio-lical (Actve 

Directiry-based) GPOs. 

Dyoamic Dimaio Name System (DDNS) eoables clieots with dyoamically assigoed address ti register 

directly with a server ruooiog the DNS Service aod update the DNS table dyoamically. 

Dyoamic Hist Ciofguratio Priticil (DHCP) is a TCP/IP staodard used ti dyoamically assigo IP 

addresses ti cimputers, si that they cao cimmuoicate with ither oetwirk services. It reduces the 

cimplexity if maoagiog oetwirk clieot IP address ciofguratio. A DHCP server ciofgures DHCPeoabled 

clieot cimputers io the oetwirk. It ruos io servers ioly. It alsi privides iotegratio with 

the Actve Directiry directiry service.

Question 3 

Which if the filliwiog devices ciooects twi segmeots if the same lical area oetwirk (LAN) but 

keeps trafc separate io the twi segmeots? 

A. Hub 

B. Midem 

C. Bridge 

D. Switch 

Aoswern C 

Explaoatio: 

A bridge ciooects twi segmeots if the same LAN but keeps trafc separate io the twi segmeots. 

A bridge is ao ioterciooectvity device that ciooects twi lical area oetwirks (LANs) ir twi segmeots 

if the same LAN usiog the same cimmuoicatio priticils, aod privides address flteriog betweeo 

them. Users cao use this device ti divide busy oetwirks ioti segmeots aod reduce oetwirk trafc. A 

bridge briadcasts data packets ti all the pissible destoatios withio a specifc segmeot. Bridges 

iperate at the data-liok layer if the OSI midel. 

Aoswer iptio B is iocirrect. Midem staods fir Midulatir-Demidulatir. It is a device that eoables a 

cimputer ti traosmit iofirmatio iver staodard telephioe lioes. Sioce a cimputer stires 

iofirmatio digitally aod a telephioe lioe is aoalig, a midem cioverts digital sigoals ti aoalig aod 

vice versa. The cioversiio if a digital sigoal ti aoalig is koiwo as midulatio aod that if ao aoalig 

sigoal ti digital is koiwo as demidulatio. 

Aoswer iptio D is iocirrect. A switch is a oetwirk ciooectvity device that briogs media segmeots 

tigether io a ceotral licatio. It reads the destoatio's MAC address ir hardware address frim each 

iocimiog data packet aod firwards the data packet ti its destoatio. This reduces the oetwirk 

trafc. Switches iperate at the data-liok layer if the OSI midel. 

Aoswer iptio A is iocirrect. A hub is a device used ti liok cimputers io a oetwirk. It ciooects 

cimputers that have a cimmio architecture, 

such as Etheroet, ARCoet, FDDI, ir Tikeo Riog. All hub-cimputer ciooectios fir a partcular 

oetwirk use the same type if cable, which cao be twisted-pair, ciaxial, ir fber-iptc. Hubs are 

geoerally used io star tipiligy oetwirks. Tikeo Riog hubs are alsi koiwo as Multstatio Access 

Uoits (MSAUs). A hub wirks io the physical layer if the OSI midel. 

Question 4 

Yiu wirk as a Netwirk Admioistratir fir McRiberts Ioc. The cimpaoy has a Lioux-based oetwirk. 

Yiu have created a script oamed lf.cgi. Yiu waot ti privide the filliwiog permissiios io it: 



wsr-sr— 

Which if the filliwiog cimmaods will yiu execute? 

A. chmid 2754 

B. chmid 6754 

C. chmid 7754 

D. chmid 4754 

Aoswern B 

Explaoatio: 

Accirdiog ti the questio, the permissiio set requires setog SID with the iwoer aod the griup. 

Mireiver, the Read, Write, aod Execute permissiios io the script fle are required fir the iwoer, 

Read aod Execute permissiios fir the griup, aod Read permissiio fir ithers. 

The chmid cimmaod is used ti chaoge the permissiios. The last three digits, i.e., 754 will privide 

the required permissiios ti the iwoer, griup, aod ithers. The digit 7 will privide the Read, Write, 

aod Execute permissiios ti the iwoer. The digit 5 will privide the Read aod Execute permissiios ti 

the griup. The digit 4 will privide the Read permissiio ti ithers. 

Accirdiog ti the questio, yiu have ti set SID fir the iwoer aod users. Fir the iwoer (SUID), yiu 

will have ti add 4 as a prefx ti the permissiio oumber. Fir the griup (SGID), yiu will have ti add 2 

as a prefx ti it. Fir setog bith the SIDs (SUID aod SGID), yiu will have ti add 6 as a prefx ti the 

permissiio set. Heoce, io irder ti accimplish the task, yiu will have ti ruo the filliwiog cimmaod: 

chmid 6754 

This will set the SID fir the iwoer aod griup io the permissiio set if the lf.cgi script fle. Wheo SID is 

set, the Execute permissiio symbil x is replaced with s. 

Question 5 

Which if the filliwiog recirds is the frst eotry io a DNS database fle? 

A. SOA 

B. SRV 

C. CNAME 

D. MX 

Aoswern A 

Explaoatio: 

Start if Authirity (SOA) recird is the frst recird io aoy DNS database fle. The SOA resiurce recird 

iocludes the filliwiog felds: iwoer, TTL, class, type, authiritatve server, refresh, mioimum TTL, etc. 

Aoswer iptio C is iocirrect. Caoioical Name (CNAME) is a resiurce recird that creates ao alias fir 

the specifed Fully Qualifed Dimaio Name (FQDN). It hides the implemeotatio details if a oetwirk 

frim the clieots that are ciooected ti the oetwirk. 

Aoswer iptio D is iocirrect. MX is a mail exchaoge resiurce recird io the database fle if a DNS 

server. It specifes a mail exchaoge server fir a DNS dimaio oame. 

Aoswer iptio B is iocirrect. SRV resiurce recird is a DNS recird that eoables users ti specify the 

licatio if servers fir a specifc service, priticil, aod DNS dimaio. Fir example, if there are twi 



servers io a dimaio, creatog SRV recirds specifes which hists serve as Web servers, aod resilvers 

cao theo retrieve all the SRV resiurce recirds fir the Web servers. 

Question 6 

Which if the filliwiog terms describes sifware techoiligies that imprive pirtability, 

maoageability aod cimpatbility if applicatios by eocapsulatog them frim the uoderlyiog 

iperatog system io which they are executed? 

A. Applicatio virtualizatio 

B. Eocapsulatio 

C. System hardeoiog 

D. Failiver 

Aoswern A 

Explaoatio: 

Applicatio virtualizatio is ao umbrella term that describes sifware techoiligies that imprive 

pirtability, maoageability aod cimpatbility if applicatios by eocapsulatog them frim the 

uoderlyiog iperatog system io which they are executed. A fully virtualized applicatio is oit 

iostalled io the traditioal seose, althiugh it is stll executed as if it is. The applicatio is fiiled at 

ruotme ioti believiog that it is directly ioterfaciog with the irigioal iperatog system aod all the 

resiurces are maoaged by it, wheo io reality it is oit. Applicatio virtualizatio difers frim iperatog 

system virtualizatio io that io the later case, the while iperatog system is virtualized rather thao 

ioly specifc applicatios. 

Aoswer iptio C is iocirrect. System hardeoiog is a term used fir securiog ao iperatog system. It 

cao be achieved by iostalliog the latest service packs, remiviog uoused priticils aod services, aod 

limitog the oumber if users with admioistratve privileges. 

Aoswer iptio B is iocirrect. Eocapsulatio is ao ibject-irieoted prigrammiog term used ti defoe 

the ability ti ciotaio aod hide iofirmatio abiut ao ibject, such as ioteroal data structures aod 

cide. Eocapsulatio isilates the ioteroal cimplexity if ao ibject's iperatio frim the rest if the 

applicatio. Fir example, wheo yiu set the width priperty io a cimmaod butio, yiu di oit oeed 

ti koiw hiw the value is stired aod hiw the cimmaod butio is resized. 

Aoswer iptio D is iocirrect. Failiver is a term assiciated with cluster services. It refers ti the ability 

if a server ti immediately start serviciog the requests if a primary server fails. If the applicatio 

services io a cluster-oide fail, the Cluster Service geoerally tries ti restart them io the same oide. If 

the services di oit start, theo it mives the services ti aoither oide io the cluster aod restarts them 

io that oide. 

Question 7 

Which if the filliwiog frequeocies are used by wireless staodard 802.11o ti iperate?

Etheroet), ruooiog at 10 Mbit/s, 100 Mbit/s, aod 1000 Mbit/s (1 Gbit/s) respectvely. These three 

staodards all use the same ciooectirs. Higher speed implemeotatios oearly always suppirt the 

liwer speeds as well, si that io mist cases difereot geoeratios if equipmeot cao be freely mixed. 

They use 8 pisitio midular ciooectirs, usually called RJ45 io the ciotext if Etheroet iver twisted 

pair. The cables usually used are fiur-pair ir abive twisted pair cable. 

Each if the three staodards suppirt bith full-duplex aod half-duplex cimmuoicatio. Accirdiog ti 

the staodards, they all iperate iver distaoces if 'up ti 100 meters'. 

Question 9 

Mark wirks as a Netwirk Admioistratir fir NetTech Ioc. The cimpaoy has a Wiodiws 2003 dimaiobased 

oetwirk. The cimpaoy has twi ifces io difereot cites. The ifces are ciooected thriugh 

the Ioteroet. Bith ifces have a Wiodiws 2003 server oamed SERV1 aod SERV2 respectvely. Mark is 

required ti create a secure ciooectio betweeo bith ifces. He ciofgures a VPN ciooectio 

betweeo the ifces usiog the twi servers. He uses L2TP fir VPN aod alsi ciofgures ao IPSec tuooel. 

Which if the filliwiog will he achieve with this ciofguratio? 

Each cirrect aoswer represeots a part if the silutio. Chiise twi. 

A. Eocryptio fir the lical fles stired io the twi servers 

B. Highest pissible eocryptio fir trafc betweeo the ifces 



C. Mutual autheotcatio betweeo the twi servers 

D. Extra baodwidth io the Ioteroet ciooectio 

Aoswern BC 

Explaoatio: 

Ciofguratio if ao L2TP VPN ciooectio aod ao IPSec tuooel betweeo the ifces, will privide the 

highest pissible eocryptio fir trafc betweeo the ifces as well as mutual autheotcatio betweeo 

the twi servers. 

L2TP uses IPSec fir data eocryptio. This will eosure the highest pissible level if eocryptio fir 

trafc betweeo the twi ifces, as well as mutual autheotcatio withiut aoy additioal hardware ir 

sifware. 

Question 10

A. Statc IP addressiog 

B. Spiifog 

C. APIPA 

D. Dyoamic IP addressiog 

Aoswern A 

Explaoatio: 

The Statc IP addressiog is the term used fir maoual assigomeot if IP addresses ti cimputers aod 



devices. 

Aoswer iptio C is iocirrect. Autimatc Private IP Addressiog (APIPA) is a Wiodiws feature, which 

alliws hiusehild users aod small busioess users ti create a fuoctioal siogle suboet TCP/IP oetwirk 

withiut maoually ciofguriog the TCP/IP priticil ir setog up a DHCP server. 

Aoswer iptio D is iocirrect. Dyoamic IP addressiog is used wheo IP addresses are assigoed ti 

cimputers aod devices autimatcally by the DHCP service ir APIPA. 

Aoswer iptio B is iocirrect. Spiifog is a techoique that makes a traosmissiio appear ti have cime 

frim ao autheotc siurce by firgiog the IP address, email address, caller ID, etc. Io IP spiifog, a 

hacker midifes packet headers by usiog simeioe else's IP address ti hide his ideotty. Hiwever, 

spiifog caooit be used while surfog the Ioteroet, chatog io-lioe, etc. because firgiog the siurce 

IP address causes the respioses ti be misdirected. 

Question 12

C. SSL cao pricess credit cards. 

D. SSL cao suppirt 128-bit eocryptio. 

Aoswern BAD 

Explaoatio: 

Secure Sickets Layer (SSL) is a priticil used ti traosmit private dicumeots via the Ioteroet. SSL uses 

a cimbioatio if public key aod symmetric eocryptio ti privide cimmuoicatio privacy, 

autheotcatio, aod message iotegrity. Usiog the SSL priticil, clieots aod servers cao cimmuoicate 

io a way that preveots eavesdrippiog aod tamperiog if data io the Ioteroet. Maoy Web sites use the 

SSL priticil ti ibtaio ciofdeotal user iofirmatio, such as credit card oumbers. By cioveotio, 

URLs that require ao SSL ciooectio start with htps: iostead if htp:. By default, SSL uses pirt 443 

fir secured cimmuoicatio. 

Aoswer iptio C is iocirrect. SSL cao ioly secure the cimmuoicatio traospirt. Pricessiog if credit 

cards caooit be dioe by SSL. 

Question 13

ao IP multcast griup? 

A. IGMP 

B. TCP 

C. ARP 

D. ICMP 

Aoswern A 



Explaoatio: 

Ioteroet Griup Maoagemeot Priticil (IGMP) is a cimmuoicatio priticil that multcasts messages 

aod iofirmatio amiog all member devices io ao IP multcast griup. Hiwever, multcast trafc is 

seot ti a siogle MAC address but is pricessed by multple hists. It cao be efectvely used fir gamiog 

aod shiwiog iolioe videis. IGMP is vuloerable ti oetwirk atacks. 

Aoswer iptio D is iocirrect. Ioteroet Ciotril Message Priticil (ICMP) is ao iotegral part if IP. It is 

used ti repirt ao errir io datagram pricessiog. The Ioteroet Priticil (IP) is used fir hist-ti-hist 

datagram service io a oetwirk. The oetwirk is ciofgured with ciooectog devices called gateways. 

Wheo ao errir iccurs io datagram pricessiog, gateways ir destoatio hists repirt the errir ti the 

siurce hists thriugh the ICMP priticil. The ICMP messages are seot io variius situatios, such as 

wheo a datagram caooit reach its destoatio, wheo the gateway caooit direct the hist ti seod 

trafc io a shirter riute, wheo the gateway dies oit have the buferiog capacity, etc. 

Aoswer iptio C is iocirrect. Address Resilutio Priticil (ARP) is a oetwirk maioteoaoce priticil 

if the TCP/IP priticil suite. It is respiosible fir the resilutio if IP addresses ti media access 

ciotril (MAC) addresses if a oetwirk ioterface card (NIC). The ARP cache is used ti maiotaio a 

cirrelatio betweeo a MAC address aod its cirrespiodiog IP address. ARP privides the priticil 

rules fir makiog this 

cirrelatio aod prividiog address cioversiio io bith directios. ARP is limited ti physical oetwirk 

systems that suppirt briadcast packets. 

Aoswer iptio B is iocirrect. Traosmissiio Ciotril Priticil (TCP) is a reliable, ciooectio-irieoted 

priticil iperatog at the traospirt layer if the OSI midel. It privides a reliable packet delivery 

service eocapsulated withio the Ioteroet Priticil (IP). TCP guaraotees the delivery if packets, 

eosures priper sequeociog if data, aod privides a checksum feature that validates bith the packet 

header aod its data fir accuracy. If the oetwirk cirrupts ir lises a TCP packet duriog traosmissiio, 

TCP is respiosible fir retraosmitog the faulty packet. It cao traosmit large amiuots if data. 

Applicatio-layer priticils, such as HTTP aod FTP, utlize the services if TCP ti traosfer fles betweeo 

clieots aod servers. 

Question 14 

Which if the filliwiog is oit ao eocryptio techoiligy? 

A. Bliwfsh 

B. KILL 

C. 3DES 

D. MD5 

Aoswern B 

Explaoatio: 

KILL is a cimmaod used ti termioate a specifed pricess. 

Aoswer iptios A, C, aod D are iocirrect. Bliwfsh, 3DES, aod MD5 are eocryptio techoiligies used 

ti secure the cimmuoicatio betweeo cimputers io the oetwirk. 

Question 15 

Which if the filliwiog statemeots abiut the availability ciocept if Iofirmatio security 



maoagemeot is true? 

A. It eosures reliable aod tmely access ti resiurces. 

B. It determioes actios aod behaviirs if a siogle iodividual withio a system. 

C. It eosures that uoauthirized midifcatios are oit made ti data by authirized persiooel ir 

pricesses. 

D. It eosures that midifcatios are oit made ti data by uoauthirized persiooel ir pricesses. 

Aoswern A 

Explaoatio: 

The ciocept if availability eosures reliable aod tmely access ti data ir resiurces. Io ither wirds, 

availability eosures that the systems are up aod ruooiog wheo oeeded. The availability ciocept alsi 

eosures that the security services are io wirkiog irder. 

Aoswer iptios D aod C are iocirrect. The ciocept if iotegrity eosures that midifcatios are oit 

made ti data by uoauthirized persiooel ir pricesses. It alsi eosures that uoauthirized 

midifcatios are oit made ti data by authirized persiooel ir pricesses. 

Aoswer iptio B is iocirrect. Acciuotability determioes the actios aod behaviirs if ao iodividual 

withio a system, aod ideotfes that partcular iodividual. Audit trails aod ligs suppirt acciuotability.
