उत्तर : 2. "A network that has only one entry and exit point."
व्याख्या :
Answer: B) A network that has only one entry and exit point. Explanation: A stub network has only one default path to non-local hosts and no outside network knowledge. Non-local stub network traffic uses a single logical path when traveling in and out of the network. Stub networks are essentially local area networks (LAN) that either do not connect to the outside and relay data packets internally or are dead-end LANs that know of only one network exit. Stub networks may have multiple connections but use one path to single points of destination. Hence, a stub network is a network that has only one entry and exit point.

उत्तर :
व्याख्या :
From the assumption and trial and error method, last three digits sum must leave the same digit as the answer. It is possible only if the answer must be units digit number leaving tens digit as carry. And the possible 3rd digit is 5. Since 5 + 5 + 5 = 15 Now, 2nd step is 1 + x + x + x = 5 => 3x = 4 It is possible with x = 8. 8 + 8 + 8 + 1 = 25 leaving 2 as carry. Now, 3rd step is 2 + x + x + x = 5 => x = 1 Hence, the three dgits are 1, 8, 5. 185 + 185 + 185 = 555.
