Accenture Interview Questions and Answers

Subnetting is the process of dividing a network into smaller subnetworks. Routers operate at the network layer (Layer 3) of the OSI model.

• Subnetting involves creating multiple smaller networks from a single larger network by dividing the IP address range.

• It helps in efficient utilization of IP addresses and improves network performance by reducing broadcast traffic.

• Routers operate at the network layer (Layer 3) of the OSI model and are responsible for forwarding data packets ...read more

ARP stands for Address Resolution Protocol, used to map IP addresses to MAC addresses. PON stands for Passive Optical Network, a type of fiber-optic network.

• ARP is used to resolve IP addresses to MAC addresses on a local network

• ARP operates at the data link layer of the OSI model

• PON is a type of fiber-optic network that uses passive optical splitters to serve multiple users

Lan card works on the Data Link layer of the OSI model.

• Lan card operates at Layer 2 of the OSI model, which is the Data Link layer.

• It is responsible for the physical addressing of devices on the network.

• Examples of Lan cards include Ethernet cards and wireless network adapters.

IP stands for Internet Protocol, a set of rules governing the format of data sent over the internet.

• IP is responsible for routing data packets between devices on a network.

• It assigns a unique address to each device on the network, known as an IP address.

• There are two versions of IP in use today: IPv4 and IPv6.

• IPv4 addresses are 32-bit numbers, while IPv6 addresses are 128-bit numbers.

• IP is a layer 3 protocol in the OSI model.

• Examples of IP-based protocols include TCP, UDP, an...read more

Mac works on the Data Link layer.

• Mac stands for Media Access Control.

• It operates on the Data Link layer of the OSI model.

• Responsible for the addressing of devices on a network.

• Examples include Ethernet MAC addresses.

IP works on the network layer (Layer 3) of the OSI model.

• IP stands for Internet Protocol.

• It is responsible for routing packets across different networks.

• IP addresses are unique identifiers assigned to devices on a network.

• Examples of IP versions include IPv4 and IPv6.

EPON and GPON are types of passive optical networks used for delivering telecommunications services.

• EPON stands for Ethernet Passive Optical Network and uses Ethernet technology for data transmission.

• GPON stands for Gigabit Passive Optical Network and offers higher bandwidth and longer reach compared to EPON.

• Both EPON and GPON are used for delivering high-speed internet, VoIP, and IPTV services to subscribers.

• EPON is more suitable for small to medium-sized deployments, while ...read more
