Welcome to the CISSP Cyber Training Podcast , where we provide you the training and tools you need to pass the CISSP exam the first time . Hi , my name is Sean Gerber and I'm your host for this action-packed , informative podcast . Join me each week as I provide the information you need to pass the CISSP exam and grow your cybersecurity knowledge .
All right , let's get started . Hey y'all , it's Sean Gerber with CISSP Cyber Trading , and I hope you all are having a beautiful day today .
Today is Thursday , exam question Thursday , so we are going to get into some exam questions around domain four , domain four of the CISSP exam , and this kind of falls in line with what we talked about on Monday as it relates to domain four and the VOIP , sip , rtr , rtp , all of these aspects of around VOIP , and so we're going to get into some questions as it
relates to domain four and voiceover , ip , along with a few others that are going to be in there as well . So let's get started , all right . So question number one and all these questions you can get at CISSP Cyber Training got to put a plug , shameless plug for CISSP Cyber Training . You can get all these questions .
Actually , I have these questions and more being added every single week . So if you want questions which is highly recommended for the CISSP exam that you take lots and lots of questions , you can get all of those at CISSP Cyber Training . Okay , now question one what protocol does VOIP primarily use for multimedia transmissions ? A SCTP Sierra , charlie , tango Papa .
B , rtp , which is your Romeo Tango Papa . C is SMTP and D is POP3 . And the answer is again what protocol does VoIP primarily use for multimedia transmissions ? The answer is RTP , real Time Transport Protocol , and this is used for transmission of audio and video .
Now , question two SIP messages are most commonly transported using which of the following protocols UDP , tcp , icmp or UDP and TCP . And again so , sip .
Sip is one of the other aspects that are tied to voiceover IP , which are messages are most commonly transported using which of the following protocols UDP , tcp , icmp or both UDP and TCP and it's true , it is D UDP and TCP .
Sip messages are most commonly transported using UDP and TCP , depending upon the network conditions of the application , then , and the requirements associated with it . Question three In VoIP implementation , which of the following is responsible for initiating a session ? So , again , the main things that are in VoIP are SIP and RDP .
So , if you see any questions outside of SIP and RTP . You might want to ask yourself a SIP , b , rtp , c , rtcp or DSDP Lots of acronyms , what are they all ? Who knows ? No , so again , which voice implementation , which following , is responsible for initiating the session SIP , rtp , rtcp or SDP ? And you basically break it down into either SIP or RTP .
Well , it is SIP . That is the session initiation protocol and it's responsible for setting up , managing and terminating sessions in a VoIP implementation . Question four which of the following is a fundamental difference between RTP and RTCP ? Oh , big words . What do we do ? I don't know More acronyms .
A RTP is used for data transport , while RTCP is used for control purposes . Hmm , maybe RTP is a control protocol and while RTCP is a transport protocol . That doesn't sound right . It supports multicast , while RTP does not . And that's Romeo , tango , charlie , papa . Rtp and RTCP serve the same purpose . Well , that's highly unlikely that they serve the same purpose .
So , when it comes right down to it , which of the following is a fundamental difference between RTP and RTCP ?
It is A RTP is used for data transport , which we talked about in our last podcast , and if you didn't know then RTCP , you could maybe guess that it's dealt for control purposes , and obviously , rtp transports the data with audio and video , while RTCP provides the feedback and the quality of the data distribution .
Okay , sip works on which of the following of the OSI layers Layer one , layer two , layer three or layer seven . Sip works on which one of the OSI layers ? It works on layer seven . Sip is the initiation protocol , again , and it operates on the application layer of the OSI model , which is layer seven .
Which of the following protocols is used for signaling of VoIP calls ? Okay , we talked about the signaling part of this , and again yet , sip , rtp , iscsi or DNS .
Well , it would be either SIP or RTP , because that's what we talked about , but SIP , again , is the initiation protocol that's designed for this and it signals that the VoIP call is going to be occurring and it helps manage those sessions . Which of the following question seven which of the following is not a function of iSCSI ?
A provide block level access to storage devices . B transmit telephone calls over the internet . C enable remote storage to be connected over standard networks . Or D enable data transfers over long distances . Okay , so obviously all of those sound very close like iSCSI , except for transmitting telephone calls over the internet . It does not .
Iscsi is a protocol used for linking storage facilities but does not have the functionality to transfer telephone calls over the internet . Question eight what port does iSCSI use by default ? Now , in this question you'd be going I don't know what port it is , but maybe you can do the part that you might be able to cut out what doesn't seem right .
So A443 , well , you know , that's not it , right , it's dealing with SSL . Okay , that's dealing with internet traffic . Or 21 , that's dealing ? Okay , remember what 21 is ? Port 21 , which would be FTP , or port 32,000 , or 3,260 ? Okay , so we know , if you go by this , 443 , 80 and 21 are using known protocols or known ports .
Now , you doesn't mean you can't use iSCSI over port 21 . Maybe you can , I don't know . But it doesn't mean you can't do that . But those are typically default ports . So which one would it be ? Most likely would be , if I was a guessing person , 3260 would be set up as a default connection for iSCSI . Which protocol enables iSCSI commands over the internet ?
Okay , talked about RTP , sip , voip , and then you got iSCSI . Obviously iSCSI , because of the internet , is designed to transport SCSI commands over IP networks , enabling you to connect to storage devices over the network as if they were local , that's iSCSI . Question 10 which protocol is used to encapsulate SCSI commands and then send them over ethernet networks ?
And you got iSCSI , sip , rtp or RTCP . And iSCSI is used , obviously , to encapsulate SCSI commands over the ethernet networks . Again allows for storage area networks to be able to be used over existing network infrastructure . Which of the following protocols would an organization use to implement IP telephony RTP , sip , rtp and SIP or RTCP ?
And the answer is RTP and SIP . Those are the ones that are used to implement IP telephone . A . Which of the following is the best way to secure SIP based VoIP traffic ? And the answer is A SIP aware firewalls . B implement TLS . C use strong authentication or D . All of the above and I would say D right . So we talk about all of these .
Now I say that we didn't talk about the SIP aware firewall , but that many of the firewalls in today's world do have that capability because they understand VoIP communications are such a large factor in almost all network activity in today's world . What function does RTCP serve in a VoIP implementation ? A data transmission , b quality of service feedback .
C initiation of the session or D termination of the session . And the answer is B quality of service feedback . The RTCP is a control protocol . Provides out of band statistics and control information for an RTP session , including quality of service and the feedback .
What type of transport is ice guzzie considered to be a block level , b file level , c packet level or D message level ? So what type of transport is ice guzzie considered to be block , file , packet or message level transport ? And the answer is A block level transport .
And lastly , which of the following protocols is an application layer protocol designed primarily to be used for establishing , modifying and terminating multimedia sessions ? Okay , a , rtp , b , sip , c , rtcp and D ice guzzie .
The answer is SIP , the session initiation protocol that operates at the application layer and is primarily used for managing multimedia communication sessions , including initiation , modification and termination . Okay , that's all the questions I have for today . I hope you guys have a wonderful day . Again . Go to CISSP , cyber training .
You can get these questions and many more that are . Some are harder , some are easier , all kinds of varying questions that you can get , based on the domain that you want to study . And again , I've got probably close to .
I was about 700 , 600 questions now , right now that are growing and I grow by at least 15 to 20 every week , if not more , so that if you want questions , cissp cyber training has the questions for you . All right , have a wonderful day and we'll catch you on the flip side , see ya .
