Solutions

S1. Ans.(b)
Sol. A private cloud refers to cloud computing resources used exclusively by a single business or organization. A private cloud can be physically located on the company’s on-site datacenter. Some companies also pay third-party service providers to host their private cloud. A private cloud is one in which the services and infrastructure are maintained on a private network.

S2. Ans.(c)
Sol. Platform as a service (PaaS) refers to cloud computing services that supply an on-demand environment for developing, testing, delivering and managing software applications. PaaS is designed to make it easier for developers to quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network and databases needed for development

S3. Ans.(e)
Sol. Layer 5 of OSI model is session layer, this layer is responsible for establishment of connection, maintenance of sessions, authentication and also ensures security. session layer is also responsible for synchronization and dialog controller.

S4. Ans.(c)
Sol. ICMP (Internet Control Message Protocol) is an error-reporting protocol network devices like routers use to generate error messages to the source IP address when network problems prevent delivery of IP packets. ICMP creates and sends messages to the source IP address indicating that a gateway to the Internet that a router, service or host cannot be reached for packet delivery. Any IP network device has the capability to send, receive or process ICMP messages.

S5. Ans.(d)
Sol. Simple Network Management Protocol (SNMP) is an application-layer protocol used to manage and monitor network devices and their functions. SNMP provides a common language for network devices to relay management information within single- and multivendor environments in a local area network (LAN) or wide area network (WAN).

S6. Ans.(b)
Sol. Class D IPv4 addresses are known as multicast IPv4 addresses. Multicasting is a technique developed to send packets from one device to many other devices, without any unnecessary packet duplication. In multicasting, one packet is sent from a source and is replicated as needed in the network to reach as many end-users as necessary. You cannot assign these IPv4 addresses to your devices. Range of class D address is: 224-239

S7. Ans.(d)
Sol. An extranet can be viewed as part of a company’s intranet that is extended to users outside the company like suppliers, vendors, partners, customers, or other business associates.

S8. Ans.(d)
Sol. Sequencing of data is a feature of Transmission Control Protocol (TCP).

S9. Ans.(a)
Sol. The Trojan Horse malware, normally appear to be useful software but will actually do damage once installed or run on your computer. Trojan Horses are normally designed to give hackers access to system. Trojan Horses will appear as useful programs but gives hackers the ability to change file settings, steal files or passwords, damage or alter files, or monitor users on computers etc.

S10. Ans.(e)
Sol. Linked List can be defined as collection of objects called nodes that are randomly stored in the memory. A node contains two fields i.e. data stored at that particular address and the pointer which contains the address of the next node in the memory. The last node of the list contains pointer to the null.
