NEW QUESTION # 807
Which of the following can be performed with software or hardware devices in order to record everything a
person types using his or her keyboard?
Answer: B
Explanation:
Keystroke logging is a method of logging and recording user keystrokes. It can be performed with software or
hardware devices. Keystroke logging devices can record everything a person types using his or her keyboard,
such as to measure employee's productivity on certain clerical tasks. These types of devices can also be used
to get usernames, passwords, etc.
Answer option C is incorrect. War dialing is a technique of using a modem to automatically scan a list of
telephone numbers, usually dialing every number in a local area code to search for computers, BBS systems,
and fax machines. Hackers use the resulting lists for various purposes, hobbyists for exploration, and crackers
(hackers that specialize in computer security) for password guessing.
Answer option A is incorrect. Warchalking is the drawing of symbols in public places to advertise an open Wi-Fi
wireless network. Having found a Wi-Fi node, the warchalker draws a special symbol on a nearby object, such
as a wall, the pavement, or a lamp post. The name warchalking is derived from the cracker terms war dialing
and war driving.
Answer option D is incorrect. An Internet Relay Chat (IRC) bot is a set of scripts or an independent program
that connects to Internet Relay Chat as a client, and so appears to other IRC users as another user. An IRC
bot differs from a regular client in that instead of providing interactive access to IRC for a human user, it
performs automated functions.
NEW QUESTION # 808
Andrew would like to configure IPsec in a manner that provides confidentiality for the content of packets. What component of IPsec provides this capability?
Answer: D
Explanation:
The Encapsulating Security Payload (ESP) component of IPsec is designed to provide confidentiality for the content of packets. ESP encrypts the data payload of IP packets to ensure that the information being transmitted remains confidential and cannot be accessed or intercepted by unauthorized parties. This encryption is crucial for protecting sensitive data as it travels across insecure networks, such as the internet.
NEW QUESTION # 809
CORRECT TEXT
Fill in the blank with the appropriate term. The ___________protocol is a feature of packet-based data transmission protocols. It is used to keep a record of the frame sequences sent and their respective acknowledgements received by both the users.
Answer:
Explanation:
Sliding Window
Explanation:
The Sliding Window protocol is a feature of packet-based data transmission protocols. It is used in the data link layer (OSI model) as well as in TCP (transport layer of the OSI model). It is used to keep a record of the frame sequences sent, and their respective acknowledgements received, by both the users. Its additional feature over a simpler protocol is that can allow multiple packets to be "in transmission" simultaneously, rather than waiting for each packet to be acknowledged before sending the next.In transmit flow control, sliding window is a variable-duration window that allows a sender to transmit a specified number of data units before an acknowledgment is received or before a specified event occurs.An example of a sliding window is one in which, after the sender fails to receive an acknowledgment for the first transmitted frame, the sender "slides" the window, i.e., resets the window, and sends a second frame. This process is repeated for the specified number of times before the sender interrupts transmission. Sliding window is sometimes called acknowledgment delay period.
NEW QUESTION # 810
Which of the following standards is approved by IEEE-SA for wireless personal area networks?
Answer: D
NEW QUESTION # 811
Which of the following protocols permits users to enter a user-friendly computer name into the Windows browser and to map network drives and view shared folders?
Answer: C
Explanation:
NetBIOS Extended User Interface (NetBEUI) is a Microsoft proprietary protocol. NetBEUI is usually used in single LANs comprising one to two hundred clients. It is a non-routable protocol. NetBEUI was developed by IBM for its LAN Manager product and has been adopted by Microsoft for its Windows NT, LAN Manager, and Windows for Workgroups products. It permits users to enter a user-friendly computer name into the Windows browser and to map network drives and view shared folders. Answer option C is incorrect. Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, Voice over Broadband (VoBB), broadband telephony, and broadband phone. VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs that encode speech, allowing transmission over an IP network as digital audio via an audio stream. Answer option A is incorrect. RADIUS is a client/server protocol that runs in the application layer, using UDP as transport. The Remote Access Server, the Virtual Private Network server, the Network switch with port-based authentication, and the Network Access Server are all gateways that control access to the network, and all have a RADIUS client component that communicates with the RADIUS server. The RADIUS server is usually a background process running on a UNIX or Windows NT machine. RADIUS serves three functions: To authenticate users or devices before granting them access to a network To authorize those users or devices for certain network services To account for usage of those services Answer option D is incorrect. Address Resolution Protocol (ARP) is a computer networking protocol used to determine a network host's Link Layer or hardware address when only its Internet Layer (IP) or Network Layer address is known. This function is critical in local area networking as well as for routing internetworking traffic across gateways (routers) based on IP addresses when the next-hop router must be determined.
