CCT 057: CISSP Exam Questions (Domain 4)

cissp domain 4 Jul 27, 2023

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.
