(b) Cast
(c) Logical
(d) Arithmetic

Q10.Which of the following mode is used whenever either end of a security association is gateway.


S1. Ans.(d)
Sol. Multiplexing (or muxing) is a way of sending multiple signals or streams of information over a communications link at the same time in the form of a single, complex signal; the receiver recovers the separate signals, a process called demultiplexing (or demuxing).

S2. Ans.(d)
Sol. Software Requirement Specification is also known as specification of Black box testing because SRS document should only specify the external behavior of a system.

S3. Ans.(b)
Sol. An event occurs when something happens in a browser window.
onDemand is not a Javascript event handler.

S4. Ans.(b)
Sol. Behavioral models are used to describe the dynamic behavior of an executing system. This can be modeled from the perspective of the data processed by the system or by the events that stimulate responses from a system.

S5. Ans.(b)
Sol. Destination MAC Address is used to decide where to forward a receive frame

S6. Ans.(d)
Sol. IPSec is an Internet Engineering Task Force (IETF) standard suite of protocols that provides data authentication, integrity, and confidentiality as data is transferred between communication points across IP networks. IPSec provides data security at the IP packet level. A packet is a data bundle that is organized for transmission across a network, and it includes a header and payload (the data in the packet). IPSec emerged as a viable network security standard because enterprises wanted to ensure that data could be securely transmitted over the Internet. IPSec protects against possible security exposures by protecting data while in transit.

S7. Ans.(a)
Sol. DHCP (Dynamic Host Configuration Protocol) is a network management protocol used to dynamically assign an Internet Protocol (IP) address to any device, or node, on a network so they can communicate using IP.

S8. Ans.(a)
Sol. The output of the program is He.

S9. Ans.(b)
Sol. Cast operator can be used to explicitly convert the value of an expression to a different data type. To do so, the name of the data type to which the conversion is to be made is enclosed in parenthesis and placed directly to the left of the expression whose value is to be converted.

S10. Ans.(a)
Sol. The Tunnel mode is used whenever either end of a security association is a gateway. Therefore, between two firewalls the tunnel mode is always used.
