Are you planning to attend an interview for the CCNP role but confused about how to crack that interview also what would be the most probable CCNP Interview Questions that the interviewer may ask? Well, you have reached the right place. Tekslate has collected the most frequently asked CCNP Interview Questions and Answers which are often asked in multiple interviews.
In this article, we will cover the following:
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 neighbour routing table
Ans: Switching makes the final ultimate delivery while routing selects the best available path in a network.
Ans: The main QoS parameters required are Bandwidth and Data loss.

Ans: There are two types of RIP messages, these request and respond.
Ans: It is routing between destinations in the same IS-IS area.
Ans: BGP uses 179 port o TCP.
Ans: 0.0.0.225
Ans: 255.255.0.0
Ans: The administrative distance for EGP is 140.
Ans: STP is used to prevent a 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 reduced to 0.
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.

Ans: No, it is a distance-vector protocol
Ans: SIP work at the Application layer of OSI.
Ans: RIP use UDP
Ans: It works at the internet layer
Ans: Hub works on the physical layer.
Ans: It is used to transfer data or files over the internet.
Ans: It is a network device that is used to balance the load on available nodes.
Ans: The main QoS parameters required are Bandwidth and Data loss.
Ans: BGP will check the next-hop attribute to determine next hop is accessible
Ans:
Ans: Administrative distance (AD) is an integer from 0 to 255 that rates the trustworthiness of routing information received on a router from a neighbouring 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.
Ans:
Ans: Distance vector routing protocols keep track of internetwork by periodically broadcasting updates out of all active interfaces. This broadcast contains the entire routing table. This method is often called routing by rumour. Slow convergence of distance vector routing protocols can cause inconsistent routing tables and routing loops.
Ans: When a router notices that a directly connected subnet has changed state, it immediately sends another routing update out of its other interfaces rather than waiting for the routing update timer to expire. Triggered updates are also known as Flash updates.
Ans: The show IP route command displays the Cisco routing table's contents.
Ans: IGRP is a Cisco proprietary distance vector routing protocol. IGRP has a default hop count of 100 hops, with a maximum hop count of 255. IGRP uses bandwidth and line delay as its default metric, but it can also use reliability, load, and MTU.
Ans: EIGRP – 224.0.0.10 OSPF – for all the routers – 224.0.0.5 OSPF – initial multicast – only for DR and BDR – 224.0.0.6
