Computer Networks

In monitoring systems like iAdmin, only monitored objects can be suppressed - that is, temporarily hidden from alerts or monitoring. Option A correctly identifies this. Options B (Mirrored object), C (Server object), and D (Network object) are not the standard terminology for objects that can be suppressed in this context.

ELAN (Emulated LAN) is an ATM technology that makes an ATM network look and behave like a traditional Ethernet LAN to connected devices. It allows LAN protocols to run over ATM networks, providing LAN emulation services. The other options describe unrelated networking concepts.

MPLS (Multiprotocol Label Switching) directs data from one node to the next based on short path labels rather than long network addresses. This technology speeds up traffic flow and makes network management more efficient compared to traditional routing. It's widely used in carrier networks.

Hyper-V virtual network adapters work with physical NICs at any standard Ethernet speed. The adapter's actual performance depends on the physical NIC speed, not a fixed limit.

Hyper-V supports three types of virtual networks: External (connected to physical network), Internal (host-to-VM communication), and Private (VM-to-VM only). All three types (D) are fully supported.

In Hyper-V networking, private networks are isolated networks that only allow communication between virtual machines on the same host. They cannot access the host OS or external physical networks. This makes them ideal for isolating VMs for testing or security purposes.

Hyper-V requires physical network adapters that are Ethernet-based. It cannot use ATM, Token Ring (legacy technologies), or wireless adapters for VM network connectivity. Only physical NICs with specific driver support are compatible.

Bluetooth uses short-wavelength UHF radio waves in the ISM band (2.4 to 2.485 GHz) as its transmission medium, not light. Distractors are true: it is named after King Harald Bluetooth, supports wireless file transfer between devices, and is frequently used for spontaneous, ad-hoc network connections.

Bluetooth is not a line-of-sight technology - it uses radio frequency waves that can penetrate walls and obstacles. LOS technologies like infrared require an unobstructed path, but Bluetooth can work through non-metallic barriers, though range and quality may be reduced.

LAN (Local Area Network) connects computers and devices within a limited geographic area like a home, office, or building. It does not require a minimum number of PCs or always include a server.

In networking terminology, any electronic device connected to a network is referred to as a 'node'. This includes computers, printers, servers, and any other addressable device on the network. A hub is a central connection point, a router directs traffic, and cable is the physical medium - none of these are general terms for network devices.

Client/server networks are designed for centralized resource management. When you need to store large databases and applications in one location that multiple users access simultaneously, a client/server architecture is necessary. Peer-to-peer networks are suitable for basic resource sharing like printers or fax machines among a small number of users, but not for centralized database management.

Peer-to-peer networks do not require dedicated server operating systems. Each computer can run a standard desktop OS like Windows 95/98 and share resources directly with others. P2P is not ideal for large file transfers, doesn't require a router (can work with just cables/hubs), and works with various cable types including copper Ethernet.

In client/server networks, the server stores shared files and resources centrally, but individual PCs can also store files locally. Client/server networks require specialized server OS (not just Windows 95/98), are designed with redundancy so one node failure doesn't crash the network, and can scale well beyond 20 nodes.

Ethernet is a family of networking technologies that defines how data is transmitted over a network. It specifies protocols at the physical and data link layers, determining how information packets travel between devices. It's not a private network (that's an intranet), doesn't need its own OS, works with various network types including peer-to-peer, and the option D text appears garbled.
