Refer to the exhibit. Traffic sourced from the loopback0 interface is trying to connect via ssh to the host at 10.0.1.15. What is the next hop to the destination address?
Answer A is incorrect. If select 10.0.1.0/28 and subnet mask is 255.255.255.240. Then, host address range will be 10.10.1.1 to 10.10.1.14.
Therefore, it coorrect answer should be B.
routing protocol does not take into consideration what the services / end user trying to do, hence SSH means nothing to routing protocol.
routing protocol just take the IP address and first match with the longest prefix, hence to answer a routing protocol question, 10.0.1.15 does fall into 10.0.1.0/28 route in the routing table.
Things like network or broadcast address have nothing to do with routing, if the address u try to access is in the subnet it will route it, no questions asked.
I think even answer B is incorrect. As there is another route in the table stating that 10.0.1.0/24 network is directly connected on Serial0.
And if I understand the previous entry conrrectly, Serial0 interface has 192.168.0.40.
(Probably) Answer C
it´s B
It should be Serial0 because of the double /24s, the connected one has lower AD.
But Serial0 isn´t listed in the options, so we have only B as a choice.
Both entries have the same administrative distance (10), but the first entry (O) has a longer prefix length (/24) compared to the second entry (D) with a shorter prefix length (/28). Since the destination IP address (10.0.1.15) falls within the range of the longer prefix (10.0.1.0/24), the first entry will be used.
Therefore, the next hop to the destination address 10.0.1.15 is:
A. 192.168.0.4
Spoke to a couple of guys and dug it up a bit, B is the correct answer, A is incorrect because router wouldn't use 10.0.1.0/28 subnet route, since the destination IP (10.0.1.15) would be a broadcast address for this subnet, so because the question states: "trying to connect via ssh" it can't be used
A is incorrect because using /28 SM 10.0.1.15 will be the broadcast address, we need a usable IP
B is inclusive of the destination address
and correct
C is incorrect, it's a host route that leads only to the host with IP 10.0.1.3
D being used as the next hop isn't even in the routing table
routing protocol does not take into consideration what the services / end user trying to do, hence SSH means nothing to routing protocol.
routing protocol just take the IP address and first match with the longest prefix, hence to answer a routing protocol question, 10.0.1.15 does fall into 10.0.1.0/28 route in the routing table.
