HCL Technologies Interview Question Bank continued from Part 1…
Q : Which of the following involves context switch – floating point exception, system call or privileged instruction?
A : System call involves context switch.
Q : What is Legacy Data?
A : Legacy data is the data contained by a system that is used prior to the installation of a new system.
Q : In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN?
A : Multiple copies of the same unicast frame is likely to be transmitted in case of an improperly implemented redundant topology.
Q : Explain VLAN.
A : VLAN (Virtual LAN) is a group of flexible logical devices (instead of physical ones) connected to one or more LANs (Local Area Networks) and are configured to communicate just like they were attached to the same wire but are actually located on a number of different LAN segments.
Q : In a Cisco mesh network, what protocol allows multiple APs (Access Points) to connect with many redundant connections between nodes?
A : AWPP (Adaptive Wireless Path Protocol) allows the above functionality.
Q : Represent E78 in radix 7.
A : E78 is a Hexadecimal (base 16) number. Convert it into Decimal (base 10) number which equals 3704. Now, convert the Decimal number 3704 to radix/base 7 by division (just as we convert Decimal to Octal/Binary/Hex) which would give 13541.
Q : What is Trunk port? Why is it needed?
A : Trunk port is a kind of port that is responsible for carrying traffic for all the VLANs that are accessible by a specific switch by a process called trunking. Trunk ports mark frames with uniquely identifying tags (either 802.1Q tags or ISL (Inter Switch Link) tags) as they move between switches. Thus every single frame can be directed to its designated VLAN.
Q : Which protocol reduces administrative overhead in a switched network by allowing the configuration of a new VLAN to be distributed to all the switches in a domain?
A : VTP (VLAN Trunking Protocol) is a Cisco propriety protocol which gives the above functionality.
Apart from above questions, there are some more questions from networking domain asked previously in HCL interviews which we have discussed in Cisco Question Bank. Also, questions from CSE/IT domains are also asked in the interviews. Some of them are already available in various posts of our Question Bank Series. Thus, it is advised to go through important concepts of CSE/IT like OOPS, Data Structures, DBMS etc. which are available on various web resources as well.
Hope this helps you!
