NEW QUESTION 99
Which of the following are the common security problems involved in communications and email?
Each correct answer represents a complete solution. Choose all that apply.
- A. Message replay
- B. Eavesdropping
- C. Message digest
- D. Message modification
- E. Message repudiation
- F. False message
- G. Identity theft
Answer: A,B,D,E,F,G
Explanation:
Following are the common security problems involved in communications and email:
Eavesdropping: It is the act of secretly listening to private information through telephone lines, e-
mail, instant messaging, and any other method of communication considered private.
Identity theft: It is the act of obtaining someone's username and password to access his/her email
servers for reading email and sending false email messages. These credentials can be obtained
by eavesdropping on SMTP, POP, IMAP, or Webmail connections.
Message modification: The person who has system administrator permission on any of the SMTP
servers can visit anyone's message and can delete or change the message before it continues on
to its destination. The recipient has no way of telling that the email message has been altered.
False message: It the act of constructing messages that appear to be sent by someone else.
Message replay: In a message replay, messages are modified, saved, and re-sent later.
Message repudiation: In message repudiation, normal email messages can be forged. There is no
way for the receiver to prove that someone had sent him/her a particular message. This means
that even if someone has sent a message, he/she can successfully deny it.
Answer option B is incorrect. A message digest is a number that is created algorithmically from a
file and represents that file uniquely.

NEW QUESTION 105
Which of the following is the practice of sending unwanted e-mail messages, frequently with commercial content, in large quantities to an indiscriminate set of recipients? Each correct answer represents a complete solution. Choose all that apply.
- A. Email spoofing
- B. Email jamming
- C. Junk mail
- D. E-mail spam
Answer: C,D
Explanation:
E-mail spam, also known as unsolicited bulk email (UBE), junk mail, or unsolicited commercial email (UCE), is the practice of sending unwanted e-mail messages, frequently with commercial content, in large quantities to an indiscriminate set of recipients. Answer option C is incorrect. Email spoofing is a fraudulent email activity in which the sender address and other parts of the email header are altered to appear as though the email originated from a different source. Email spoofing is a technique commonly used in spam and phishing emails to hide the origin of the email message. By changing certain properties of the email, such as the From, Return-Path and Reply-To fields (which can be found in the message header), ill-intentioned users can make the email appear to be from someone other than the actual sender. The result is that, although the email appears to come from the address indicated in the From field (found in the email headers), it actually comes from another source. Answer option D is incorrect. Email jamming is the use of sensitive words in e-mails to jam the authorities that listen in on them by providing a form of a red herring and an intentional annoyance. In this attack, an attacker deliberately includes "sensitive" words and phrases in otherwise innocuous emails to ensure that these are picked up by the monitoring systems. As a result the senders of these emails will eventually be added to a "harmless" list and their emails will be no longer intercepted, hence it will allow them to regain some privacy.
NEW QUESTION 106
FILL BLANK
Fill in the blank with the appropriate term. In computing, ______________ is a class of data storage devices
that read their data in sequence.
Answer:
Explanation:
SAM
Explanation:
In computing, sequential access memory (SAM) is a class of data storage devices that read their data in
sequence. This is in contrast to random access memory (RAM) where data can be accessed in any order.
Sequential access devices are usually a form of magnetic memory. While sequential access memory is read in
sequence, access can still be made to arbitrary locations by "seeking" to the requested location. Magnetic
sequential access memory is typically used for secondary storage in general-purpose computers due to their
higher density at lower cost compared to RAM, as well as resistance to wear and non-volatility. Examples of
SAM devices include hard disks, CD-ROMs, and magnetic tapes.

NEW QUESTION 108
Which of the following devices allows wireless communication devices to connect to a wireless network using Wi-Fi, Bluetooth, or related standards?
- A. Wireless repeater
- B. WNIC
- C. WAP
- D. Express card
- E. None
Answer: C
Explanation:
A wireless access point (WAP) is a device that allows wireless communication devices to connect to a wireless network using Wi-Fi, Bluetooth, or related standards. The WAP usually connects to a wired network, and it can transmit data between wireless devices and wired devices on the network. Each access point can serve multiple users within a defined network area. As people move beyond the range of one access point, they are automatically handed over to the next one. A small WLAN requires a single access point. The number of access points in a network depends on the number of network users and the physical size of the network.
Answer option C is incorrect. A wireless network interface card (WNIC) is a network card that connects to a radio-based computer network, unlike a regular network interface controller (NIC) that connects to a wire- based network such as token ring or ethernet. A WNIC, just like a NIC, works on the Layer 1 and Layer 2 of the OSI Model. A WNIC is an essential component for wireless desktop computer. This card uses an antenna to communicate through microwaves. A WNIC in a desktop computer is usually connected using the PCI bus.
Answer option A is incorrect. ExpressCard, a new standard introduced by PCMCIA, is a thinner, faster, and lighter modular expansion for desktops and laptops. Users can add memory, wired or wireless communication cards, and security devices by inserting these modules into their computers. ExpressCard slots are designed to accommodate modules that use either Universal Serial Bus (USB) 2.0 or the PCI Express standard.
ExpressCard modules are available in two sizes, i.e., 34 mm wide (ExpressCard/34) and 54 mm wide (ExpressCard/54). Both modules are 75 mm long and 5 mm high. An ExpressCard/34 module can be inserted in either a 54 mm slot or a 34 mm slot, but an ExpressCard/54 requires a Universal (54 mm) slot. However, an extender can be used with ExpressCard/34 slot to connect the ExpressCard/54 module from outside of the computer. Both the modules are identical in performance. They take full advantage of the features of the PCI Express or USB 2.0 interfaces. The only difference between them is that the ExpressCard/54 form-factor, due to its larger surface area, allows for greater thermal dissipation than does an ExpressCard/34. As the performance does not vary with module size, module developers usually prefer to fit their applications into the smaller ExpressCard/34 form factor. But some applications, such as SmartCard readers, and CompactFlash readers, require the extra width of an ExpressCard/54 module.
Answer option D is incorrect. A wireless repeater is a networking device that works as a repeater between a wireless router and computers. It is used to connect a client to the network when the client is out of the service area of the access point. If the wireless repeater is configured properly, it extends the range of the wireless LAN network.

NEW QUESTION 113
Which of the following protocols uses a control channel over TCP and a GRE tunnel operating to encapsulate
PPP packets?
- A. LWAPP
- B. SSTP
- C. PPTP
- D. ESP
Answer: C
Explanation:
The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP
uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets. The PPTP
specification does not describe encryption or authentication features and relies on the PPP protocol being
tunneled to implement security functionality. However, the most common PPTP implementation, shipping with
the Microsoft Windows product families, implements various levels of authentication and encryption natively as
standard features of the Windows PPTP stack. The intended use of this protocol is to provide similar levels of
security and remote access as typical VPN products.
Answer option B is incorrect. Encapsulating Security Payload (ESP) is an IPSec protocol that provides
confidentiality, in addition to authentication, integrity, and anti-replay. ESP can be used alone or in combination
with Authentication Header (AH). It can also be nested with the Layer Two Tunneling Protocol (L2TP). ESP
does not sign the entire packet unless it is being tunneled. Usually, only the data payload is protected, not the
IP header.
Answer option D is incorrect. Secure Socket Tunneling Protocol (SSTP) is a form of VPN tunnel that provides a
mechanism to transport PPP or L2TP traffic through an SSL 3.0 channel. SSL provides transport-level security
with key-negotiation, encryption, and traffic integrity checking. The use of SSL over TCP port 443 allows SSTP
to pass through virtually all firewalls and proxy servers. SSTP servers must be authenticated during the SSL
phase. SSTP clients can optionally be authenticated during the SSL phase, and must be authenticated in the
PPP phase. The use of PPP allows support for common authentication methods, such as EAP-TLS and MS-
CHAP. SSTP is available in Windows Server 2008, Windows Vista SP1, and later operating systems. It is fully
integrated with the RRAS architecture in these operating systems, allowing its use with Winlogon or smart card
authentication, remote access policies, and the Windows VPN client.
Answer option C is incorrect. LWAPP (Lightweight Access Point Protocol) is a protocol used to control multiple
Wi-Fi wireless access points at once. This can reduce the amount of time spent on configuring, monitoring, or
troubleshooting a large network. This also allows network administrators to closely analyze the network.
