What is the main function of a router ?
A. Determine the best path to send packets.
B. Distribute packets in the network
C. Forward Packets to their destinations
Both A and B
When router receives a packet, it determines the best path by:
opening the packet and then eating it.
decapsulating the packet, storing the information and then checking the address table.
encapsulating the packet, adding the mac address and then Hoping for the best.
checking destination address of packet and then checking routing table.
What is known as routing ?
When IP packets from source is sent to the router and forwarded by router using a pre-determined interface.
When information is sent from source to router and information of path recorded.
When IP packets from destination is sent to the router and received by source using an unknown interface.
While building a routing table, what are the 3 concepts made to be considered in the router based network ?
1. Router Topology Network
2. Connection status of devices
3. Static Networks
1. Dynamic Networks
2. Static Networks
3. Sub Networks and Main Networks
1. Directly Connected Networks
2. Remote Networks
3. Default Route
What is the purpose of the "ip route" command in Cisco IOS ?
{Router(config)# ip route <ipv4 address> <subnet mask>}
To configure a default route on the router
To configure a static route on the router
To enable dynamic routing protocols on the router
To configure VLANs on the router
What does "s0/0/0" represent in the command " Router1(config)# ip route 192.168.1.1 255.255.255.0 s0/0/0 " ?
The IP address of the next-hop router
The interface used to reach the next-hop router
The subnet mask for the destination network
The administrative distance of the route
What is the purpose of the command "Router(config)# ip address 192.168.1.1 255.255.255.0 "?
To configure a default gateway on the router
To configure a subnet mask on the router
To configure an IPv6 address on the router
To configure an IPv4 address on the router
What is the purpose of the command "Router(config)# ipv6 address 2001:db8:1111:cafe:0010::1/64"?
To configure a subnet mask on the router
To configure an IPv6 EUI based address on the router
To configure an IPv6 address on the router
To configure a default gateway on the router
What is the purpose of the command "Router(config)# ip address fe80::a2:1"?
To enable Link-Local addressing on the router and interfaces
To assign an IPv6 address to the interface
To enable Link-Local addressing on the interface
To configure a static route on the router
What is the command to, Add the logging synchronous command to the console and virtual terminal lines of all the routers.
(a)
The command to input ipv6 address is (Subnet) (a) /_(Prefix) for " 2001:DB8:1111:2::2/64 "
What are the commands for the CLI interface, to input/setup the following,
Change hostname to R3
R3 to provide stateless DHCPv6 for PCs of R3 LAN. (name R3-Stateless)
(a)
Is this true or false ?
True
False
What is the command to Prevent interruption due to logs during router configuration on both console and
virtual terminals.
router(config)# logging console warnings
router(config)# logging host <IP_address>
router(config)# no ip domain-lookup
router(config)# security passwords min-length 10
What is the command to, Encrypt all the user passwords.
router(config)# password-encryption service
router(config)# all password-encryption
router(config)# service password-encryption
None of the above
Why is the subnet of the destination interface given rather than the ip of the destination in the command "R3(config)# ipv6 route 2001:db8:1111:1::/64 s0/0/1"
Router forwards packets till they reach the destination, as such subnet hints to the destination.
Router recieves packets till they reach the destination, as such destination is found eventually.
Router encapsulates packets till they reach the destination, as such the destination is recorded in the router.
Router forwards packets till they reach the destination, as such the hop router needs to know the general route to destination
What is use to store, Running configuration files ?
NVRAM
RAM
Flash
ROM
The three possible outcomes of Packet forwarding decision are;
1. Forward Packet Directly to Destination Device
2. Forward Packet to Next-hop Router
3. Forward Packet to the Remote Destination
4. Discard packets with no matching route
What are the 3 planes that define a router and other hardware in Software Defined Netoworking ?
Management Plane, Control Plane and Data Plane
Internet Plane, Data-link Plane and Physical Plane
TCP/IP Plane, UDP Plane and ND Plane
CPU configured Plane, Cable Configured Plane and Data base Plane
What is the full form of FIB in terms with routing, in the field of networking ?
Fast Information Broadband
Forwarding Internet Base
Forwarding Interim Broadband
Forwarding Information Base
Among the 3 routing table information, which defines information need to be explicitly forwarded.
•Principle 1 : Every router makes its decision alone, based on the information it has in its own routing table.
•Principle 2 : The information in a routing table of one router does not necessarily match the routing table of another router.
•Principle 3 : Routing information about a path does not provide return routing information.
Principle 2
Principle 3
Principle 1
Both Principle 1 and Principle 2
Both Principle 2 and Principle 3
What is the similarity in Static Routing and Dynamic routing ?
They both determine IP for interfaces and PC.
They help network administrators to control IP in a network.
They define paths to send information between two or more networking devices.
They help students to understand the concept of networking and make industry level understanding easy.
