SOLUTIONS

 

S1. Ans.(c)

Sol. Elasticity is the degree to which a system is able to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner. It has the ability to right-size resources as required.

 

 

S2. Ans.(b)

Sol. Spyware is a software that is installed on your computer directly or indirectly. It monitors different programs, internet activity secretly while running in background of your computer.

 

 

S3. Ans.(a)

Sol. Overlaying is the process of transferring a block of program code or other data into internal memory, replacing what is already stored. This technique allow programs to be larger than the computer’s main memory.

 

 

S4. Ans.(d)

Sol.  Extensible Hypertext Markup Language (XHTML) is part of the family of XML markup languages.

 

 

S5. Ans.(c)

Sol.

  • Secure Sockets Layer (SSL) is a networking protocol designed for securing connections between web clients and web servers over an insecure network like internet.
  • TLS is Acronym of Transport Layer Security.

Both are cryptographic protocols designed to provide communications security over a computer network.

 

 

S6. Ans.(d)

All of the above

 

S7. Ans.(d)

Sol. IPv6 supports unicast, multicast and anycast addressing modes.

 

S8. Ans.(b)

Sol. Virtualization enables the migration of the virtual image from one physical machine to another. Virtualization allows to share a single physical instance of a resource or an application among multiple customers and organizations at one time. It helps in optimization by sharing data to different machines.

 

 

S9. Ans.(c)

Sol. An Antivirus Signature is a set of unique data or bits of code for its identification. Anti-virus software uses the virus signature to scan for the presence of malicious code.

 

 

S10. Ans.(b)

A number of tuples.
