Question
11. (TCO 3) A network engineer types the following commands on a production (live) router that is connected to a WAN link from NY to CA.
interface serial 0/3/1
ip address 206.167.54.1 255.255.255.0
description "Connection to CA."
no shutdown
interface serial 0/3/1
ip address 198.20.34.56 255.255.255.0
end
What IP address or addresses would the router have on interface Serial 0/3/1? (Points : 3) Both 206.167.54.1 and 198.20.34.56
The router will keep the original 206.167.54.1 address.
The router will have only 198.20.34.56 address.
There is not enough information provided to answer the question.
None of the above
The router will be assigned an autonomous system number of 64.
The router will be assigned a router ID of 64.
The reference bandwidth will be set to 64 Mb/s.
The OSPFv3 process will be assigned an ID of 64.
Answers A and C are correct.
The next-hop IP address
The Method used to assign the address
The IP address of the ingress interface
None of the above
Explanation / Answer
11.
interface serial 0/3/1
ip address 206.167.54.1 255.255.255.0
description "Connection to CA."
no shutdown
After executing the above command the serial interface of the router is assigned with the ip address 206.167.54.1
interface serial 0/3/1
ip address 198.20.34.56 255.255.255.0
end
After executing the above command the serial interface of the router is assigned with the ip address 198.20.34.56
Router have 198.20.34.56 IP address on the serial interface 0/3/1
12.
Show interface brief shows the method of ip assignment along with the interface and the IP address assigned to the interface.
Show ip interface brief command displays the following information:
The Method used to assign the address
The IP address of the ingress interface
13.
The measure of the probability that a network is available to use when it is required is called its availability.
Hence the correct answer is availability.
14.
The IPv6 has ultimate routes and 64 bit subnet mask whereas IPv4 has 32 bit subnet mask and it may or may not have ultimate routes.
Hence, the correct options are as follows:
By design IPv6 subnet mask must be 64 bit long unlike variable length subnet mask in IPv4.
By design IPv6 is classless so all routes are effectively level-1 ultimate routes.
15.
Next-hop address and link interface are essential to have an ultimate route in a routing table.
Hence the correct answer is Next-hop address.
16.
Updates are triggered in ospf when the link goes down or the topology table or routing table gets updated.
Hence the correct answer is None of the above.
17.
BGP is an external gateway routing protocol and is used to connect two different organizations.
Hence the correct answer is BGP.
18.
RIPv2 is compatabile with RIP version 1 hence it can send and receive the RIPv1 packet but it is given in question receive 2. Router gateway is given in configuration as 192.168.1.9. Since the configuration dispalys connection to one serial port and one ethernet so, the network must be connected to one router by the serial interface and to LAN by ethernet so it is having one neighbor router.
Hence the correct answer is This router’s Gateway of Last Resort is 192.168.1.9.
19.
Show ip route ospf is used to extract information specific OSPFv2 routes in the routing table
Hence the correct answer is show ip route ospf.
20.
In the configuration mode ospf has been given the process id 64.
Hence the correct answer is The OSPFv3 process will be assigned an ID of 64.
