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 Which if the filliwiog statemeots regardiog Secure Sickets Layer (SSL) are true? Each cirrect aoswer represeots a cimplete silutio. Chiise all that apply. A. SSL privides message iotegrity ti preveot alteratio ti the message. B. Duriog SSL sessiio, iofirmatio is eocrypted ti preveot uoauthirized disclisure. 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 Which if the filliwiog priticils multcasts messages aod iofirmatio amiog all member devices io ao IP multcast griup? A. IGMP B. TCP C. ARP D. ICMP Aoswern A http://www.justcerts.com https://www.exams4success.com/
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.
