- Q1. 1- How ping / Traceroute work?
- Ans.
Ping and Traceroute are network diagnostic tools used to test connectivity and identify network issues.
Ping sends a small packet of data to a destination IP address and waits for a response. It measures the time it takes for the packet to travel to the destination and back.
Traceroute sends packets with increasing TTL values to the destination, and each router along the path sends back an ICMP message indicating its pre...
- Q2. How OSPF build its database?
- Ans.
OSPF builds its database by exchanging LSAs with neighboring routers.
OSPF routers exchange Hello packets to establish adjacency.
Once adjacency is established, routers exchange Link State Advertisements (LSAs).
LSAs contain information about the router's interfaces, neighbors, and network topology.
Each router builds its own database based on the LSAs it receives.
The database is used to calculate the shortest path to each...
- Q3. What is NSSA area in OSPF and why it is used for ?
- Ans.
NSSA area is a type of OSPF area that allows external routes to be injected into the OSPF domain.
NSSA stands for Not-So-Stubby-Area.
It is used when an area needs to import external routes but still wants to maintain some level of stubbiness.
NSSA area has an ABR (Area Border Router) that translates Type 7 LSAs (Link State Advertisements) into Type 5 LSAs.
Type 7 LSAs are generated by ASBR (Autonomous System Boundary Rout...
- Q4. Can we implement MPLS without RT and RD?
- Ans.
No, RT and RD are required for MPLS VPN implementation.
RT (Route Target) and RD (Route Distinguisher) are used to uniquely identify VPN routes.
Without RT and RD, MPLS VPN cannot differentiate between different VPN routes.
RT and RD are used to import and export VPN routes between different VPNs.
RT and RD are also used for route filtering and traffic engineering.
Therefore, RT and RD are essential for MPLS VPN implementat

- Q1. What is rating of llop
- Ans.
The rating of llop refers to the Load Line Operating Power of a network device.
Rating of llop is a measure of the maximum power a network device can operate at.
It is important for ensuring the device does not exceed its power limits.
For example, a switch may have a rating of llop of 250W, meaning it can operate at a maximum power of 250 watts.
- Q2. How many max sectors run on tower
- Ans.
The maximum number of sectors that can run on a tower depends on various factors such as tower capacity, network traffic, and hardware specifications.
The maximum number of sectors that can run on a tower is typically determined by the tower's capacity and the network traffic it needs to handle.
Factors such as hardware specifications, signal strength, and interference can also impact the maximum number of sectors that c...

Optical fibre is a thin, flexible, transparent fibre made of glass or plastic that can transmit light signals over long distances.
Optical fibre is used in telecommunications to transmit data at high speeds.
It consists of a core, which carries the light signals, surrounded by a cladding layer that reflects the light back into the core.
The core and cladding are protected by a buffer coating to prevent damage.
Optical fibr...
