Centralized security management

What is a primary disadvantage of peer-to-peer networks?

Difficult to administer and secure

Slow communication between devices

In a client-server model, how do clients communicate with each other?

Through direct peer-to-peer communication

By broadcasting messages to all clients

Through a personal area network (PAN)

What type of network would you typically find in a single office building?

Metropolitan Area Network (MAN)

Which network type is used to connect different buildings in the same city?

Metropolitan Area Network (MAN)

What type of network typically provides slower throughput than a local area network?

Wireless Local Area Network (WLAN)

What is the key feature of a software-defined wide area network (SDWAN)?

It defines routing based on data types and needs

It provides cloud-based services

It eliminates the need for a central data center

What is the main difference between a NAS and a SAN?

NAS is a file-level storage, while SAN is a block-level storage.

NAS is used for personal storage, while SAN is used for enterprise storage.

NAS allows block-level access, while SAN allows file-level access. SAN allows block-level access, while NAS allows file-level access. NAS is used in personal networks, while SAN is used in enterprise networks. SAN is used for backups, while NAS is used for streaming data.

SAN allows block-level access, while NAS allows file-level access

NAS allows block-level access, while SAN allows file-level access

NAS is used in personal networks, while SAN is used in enterprise networks

SAN is used for backups, while NAS is used for streaming data

What is a common feature of a star topology?

Devices connect to a central hub or switch

Devices are directly connected to each other

Devices form a ring to provide redundancy

Devices communicate through a single bus cable

Why did early Ethernet networks move away from using a bus topology?

Because a single break in the bus could cause network failure

Because bus networks were too expensive

Because bus networks did not support wireless communication

Because bus networks were too slow

What is the key advantage of a mesh topology?

Direct connection between all devices

What is a hybrid network topology?

A network that combines two or more different topology types

A network that only uses a star topology

A network that only uses a ring topology for redundancy

A network that only uses ad hoc wireless communication

In a mesh network, what is the advantage of self-healing?

It ensures the network continues to function even if a device goes offline

It increases the range of the network

It reduces the overall number of devices needed

It makes the network immune to security threats
