Networking problems
- 1. What is the main reason the OSI Model was created? Also asked in: Analyst, Bank Clerk, Database Administrator, Network Engineer
Correct Answer: The OSI Model is used as a reference model The primary reason the OSI model was created was so that different networks could inter-operate Hence, different networks could communicate
- 2. Physical or logical arrangement of network is
Options- A. Topology
- B. Routing
- C. Both A & B
- D. Networking Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk, Bank PO, Database Administrator, IT Trainer, Network Engineer
Correct Answer: Topology
Explanation:
The logical arrangement of the nodes of different networks to communicate is called as topology.
- 3. What is cladding? Also asked in: Network Engineer
Correct Answer: A layer of a glass surrounding the center fiber of glass inside a fiber-optic cable
- 4. What are the data units at different layers of the TCP / IP protocol suite? Also asked in: Network Engineer
Correct Answer: The data unit created at the application layer is called a message, at the transport layer the data unit created is called either a segment or an user datagram, at the network layer the data unit created is called the datagram, at the data link layer the datagram is encapsulated in to a frame and finally transmitted as signals along the transmission media
- 5. How long is an IPv6 address?
Options- A. 128 bytes
- B. 32 bits
- C. 128 bits
- D. 32 bytes Also asked in: AIEEE, Bank Exams, Analyst, Bank PO, Database Administrator, IT Trainer, Network Engineer
Correct Answer: 128 bits
Explanation:
IPv6 - Internet Protocol Version 6.
IPv6 addresses have a size of 128 bits.
Internet Protocol Version 6 [IPv6] is the successor to the Internet's first addressing infrastructure, Internet Protocol version 4 (IPv4).
In contrast to IPv4, which defined an IP address as a 32-bit value, IPv6 address have a size of 128 bits.
- 6. Different IP address on same network? Also asked in: Analyst, Bank Clerk, Database Administrator, IT Trainer
Correct Answer: There are two IP address assigned to each device on a Wi-Fi network An Internal (Private) and an External (Public) IP address Internal IP address is used for communication between Your computer and a smartphone or whatever devices that are connected to that Wifi network This is unique for each If they are same the system cannot differentiate between each device While, the External IP address is that visible to the the internet - the websites, the internet connected Apps so on By default, Routers with NAT (all routers today have it) assign same Public IP address to all devices under its network
- 7. What is RAID? Also asked in: Network Engineer
Correct Answer: A method for providing fault tolerance by using multiple hard disk drives
- 8. IP address of a packet is normally analyzed by
Options- A. Modem
- B. Router
- C. Hub
- D. CPU Also asked in: Bank Exams, Bank PO, Bank Clerk, Analyst, Database Administrator, IT Trainer, Network Engineer
Correct Answer: Router
Explanation:
The IP address of a packet is normally analyzed by Router.
- 9. Which address identifies a process on a host?
Options- A. Port
- B. Physical
- C. IP
- D. All of the above Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk, Bank PO, Database Administrator, IT Trainer, Network Engineer
Correct Answer: Port
- 10. Transmission data rate is decided by
Options- A. Transport layer
- B. Network layer
- C. Physical layer
- D. Data link layer Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk, IT Trainer, Network Engineer
Correct Answer: Physical layer
Explanation:
The speed of the transmission data is generally determined by the cables or connectors we use for data transmission. In networking, layer-1 the physical is which deals with the network cables like pins, usb, connectors, etc... we use for data transmission.
