Question 71

Adam, a malicious hacker, has just succeeded in stealing a secure cookie via a XSS attack. He is able to
replay the cookie even while the session is valid on the server. Which of the following is the most likely reason
of this cause?

A.No encryption is applied.
B.Two way encryption is applied.
C.Encryption is performed at the network layer (layer 1 encryption).
D.Encryption is performed at the application layer (single encryption key).

Question 72

Token Ring is standardized by which of the following IEEE standards?

A.802.3
B.802.4
C.802.1
D.802.2

Question 73

Which of the following protocols is described as a connection-oriented and reliable delivery transport layer protocol?

A.SSL
B.UDP
C.TCP
D.IP

Question 74

Which of the following OSI layers establishes, manages, and terminates the connections between the local and remote applications?

A.Data Link layer
B.Network layer
C.Application layer
D.Session layer

Correct Answer: D

The session layer of the OSI/RM controls the dialogues (connections) between computers. It establishes, manages and terminates the connections between the local and remote application. It provides for full-duplex, half-duplex, or simplex operation, and establishes checkpointing, adjournment, termination, and restart procedures. The OSI model made this layer responsible for graceful close of sessions, which is a property of the Transmission Control Protocol, and also for session checkpointing and recovery, which is not usually used in the Internet Protocol Suite. The Session Layer is commonly implemented explicitly in application environments that use remote procedure calls.
Answer option C is incorrect. The Application Layer of TCP/IP model refers to the higher-level protocols used by most applications for network communication. Examples of application layer protocols include the File Transfer Protocol (FTP) and the Simple Mail Transfer Protocol (SMTP). Data coded according to application layer protocols are then encapsulated into one or more transport layer protocols, which in turn use lower layer protocols to affect actual data transfer.
Answer option A is incorrect. The Data Link Layer is Layer 2 of the seven-layer OSI model of computer networking. It corresponds to or is part of the link layer of the TCP/IP reference model. The Data Link Layer is the protocol layer which transfers data between adjacent network nodes in a wide area network or between nodes on the same local area network segment. The Data Link Layer provides the functional and procedural means to transfer data between network entities and might provide the means to detect and possibly correct errors that may occur in the Physical Layer. Examples of data link protocols are Ethernet for local area networks (multi-node), the Point-to-Point Protocol (PPP), HDLC, and ADCCP for point-to-point (dual-node) connections.
Answer option B is incorrect. The network layer controls the operation of subnet, deciding which physical path the data should take, based on network conditions, priority of service, and other factors. Routers work on the Network layer of the OSI stack.

Question 75

Mark works as a Network Administrator for Infonet Inc. The company has a Windows 2000 Active Directory domain-based network. The domain contains one hundred Windows XP Professional client computers. Mark is deploying an 802.11 wireless LAN on the network. The wireless LAN will use Wired Equivalent Privacy (WEP) for all the connections. According to the company's security policy, the client computers must be able to automatically connect to the wireless LAN. However, the unauthorized computers must not be allowed to connect to the wireless LAN and view the wireless network. Mark wants to configure all the wireless access points and client computers to act in accordance with the company's security policy. What will he do to accomplish this? Each correct answer represents a part of the solution. Choose three.

A.Install a firewall software on each wireless access point.
B.Configure the authentication type for the wireless LAN to Shared Key.
C.Disable SSID Broadcast and enable MAC address filtering on all wireless access points.
D.Broadcast SSID to connect to the access point (AP).
E.Configure the authentication type for the wireless LAN to Open system.
F.On each client computer, add the SSID for the wireless LAN as the preferred network.
