Ans: It is used when there is no specific entry in the routing IP table. Ans: RIP broadcast its routing table after every 30 seconds while OSPF only update those entries which are missing the neighbor routing table.
Ans: Switching makes the final ultimate delivery while routing selects the best available path in a network. Ans: There are two types of RIP messages, these request and respond. Q8 What will be the wildcard address for Ans: 0. Q9 What will be the netmask for the Ans: Q10 What is the administrative distance of EGP?
Ans: The administrative distance for EGP is Ans: STP is used to prevent switching loop in the switching network, while RSTP is almost the same as STP just only one thing which is the timing of port forwarding has been reducing to 0. Q12 What is a core network? Ans: A core network is where the entire main network lives. Without a core network, the whole network cannot be run. All routers and switches are connected to their core network. Q13 Is RIP v2 is the link-state protocol?
Ans: No, it is a distance-vector protocol. Q14 At which layer SIP protocol work? Q15 Which protocol does RIP use to transport data? Ans: It works at the internet layer. Q17 At which layer HUB work? Ans: Hub works on the physical layer.
Ans: It is used to transfer data or files over the internet. Q19 What is a load balancer? Ans: It is a network device that is used to balance the load in on available nodes.
Q20 What QoS parameters are required to transfers credential files from one source to a destination? Q21 What will the BGP first check to see if a prefix is accessible? Ans: BGP will check the next-hop attribute to determine next hop is accessible. Q22 What is the AD for each of the following?
Ans: Administrative distance AD is an integer from 0 to that rates the trustworthiness of routing information received on a router from a neighboring router. The AD is used as the tiebreaker when a router has multiple paths from different routing protocols to the same destination.
The path with the lower AD is the one given priority. Q24 What are the three classes of routing protocols? Distance vector Link-state Balanced hybrid Q25 How do distance vector routing protocols keep track of any changes to the internetwork? Ans: Distance vector routing protocols keep track of an internetwork by periodically broadcasting updates out all active interfaces.
This broadcast contains the entire routing table. This method is often called routing by rumor. Slow convergence of distance vector routing protocols can cause inconsistent routing tables and routing loops. Q26 What have triggered updates? Ans: When a router notices that a directly connected subnet has changed state, it immediately sends another routing update out its other interfaces rather than waiting for the routing update timer to expire.
Triggered updates are also known as Flash updates. Q27 How do you display the contents of a Cisco IP routing table? Ans: The show IP route command displays the Cisco routing table's contents. IGRP has a default hop count of hops, with a maximum hop count of CCNP Tutorial.

Answer : The function of Switching is to Switch data packets between devices on the same network. Unlike hubs, switches examine each packet and process it accordingly rather than simply repeating the signal to all ports. Question 3. Answer : Hub is designed to connect hosts to each other with no understanding of what it is transferring. When a Hub receives a packet of data from a connected device, it broadcasts that data packet to all other ports regardless of destination port.
Post a comment. Pages Home. What is a Firewall? Firewall is a device that is placed between a trusted and an untrusted network. It deny or permit traffic that enters or leaves network based on pre-configured policies.

Routing is the process of finding a path on which data can pass from source to destination. Routing is done by a device called routers, which are network layer devices. The job of the Data Link layer is to check messages are sent to the right device.
And we were at the Capuchin Crypt where the second was, head turned toward me. This would cost him the use of some patrol boats. A handshake was the protocol between Crow and me. She held a dishcloth in her hand.
There is parcel of chances from many presumed organizations on the planet.
Джабба нажал на клавишу. И в следующую секунду все присутствующие поняли, что это было ошибкой. ГЛАВА 119 - Червь набирает скорость! - крикнула Соши, склонившаяся у монитора в задней части комнаты. - Неверный ключ.
Телефонистка нервно проглотила слюну.
Теперь он уже бежал по узкому проходу. Шаги все приближались. Беккер оказался на прямом отрезке, когда вдруг улочка начала подниматься вверх, становясь все круче и круче. Он почувствовал боль в ногах и сбавил скорость.
Сколько я уже тут кручусь. Однако считать ему не хотелось. По профессиональной привычке поправив съехавший набок узел галстука, он повернулся к писсуару.
