8. How will CMDB continue to evolve shortly? Answer: CMDB will continue to evolve as the technology around it evolves –- as we have seen with the introduction of cloud/virtual infrastructure.
In terms of predictions- In ITIL v3, we were introduced to the concept of the Service Knowledge Management System or SKMS, and we feel that this will continue to develop. This is the set of tools, processes, and databases used to manage knowledge and information. This includes the CMS, trusted sources, CMDBs, the SACM process and anything else required to turn data into wisdom. After all, that is why you are collecting this data in the first place –- so that it can be re-used.
As Social IT becomes more prevalent, a new community-driven, organically growing knowledge repository will quickly overtake the static knowledge bases of old. IT will no longer be the gatekeepers of knowledge, but will retain responsibility for storing it; possibly indexing it, and making it accessible to the business. The CMDB will play a key part in this knowledge revolution –- and may end up as the repository for knowledge about CIs, in addition to the configuration and relationships stored there today.
The other prediction that we would make would be in the area of automatic remediation –- and we have customers doing this today using our CMDB in conjunction with our Runbook Automation capability. In these situations, customers are identifying issues with CIs (perhaps non-standard configurations or similar) and then using runbook automation to automatically remediate those issues with zero-touch.
9. why do we have an hourly rate in a group? Answer: Once the Project Management v2 Costing Add-on Plugin is installed Group Hourly rate is displayed.
The plugin creates an Hourly rate field on the Group form and adds a new form called Group resource, which calculates the estimated cost for the group, based on the hourly rate provided. The Group Resources will be added automatically based on the groups associated with the Project or its associated Project Tasks.
Defines the hourly rate for members of this group, as defined in the Group record, The hourly rate is multiplied by the Estimated hours for the group to estimate project costs.
10. Which searching technique is used to search a text or record in ServiceNow? Answer: Zing is the text indexing and search engine that performs all text searches in ServiceNow.
11. What is your biggest weakness?
Answer: The dreaded interview question: What is your greatest weakness? It’s often debated, but we have insight from our top ServiceNow consultants who have successfully prepared candidates for interviews; you should be honest about your technical areas for improvement and your commitment to learning new skills. This will handle the interviewers’ potential objections up-front, however, it is very important to never give generic weaknesses such as ‘I work too hard.’
- Approach your interview feeling confident in your skillset and knowledge. Remember, you are the expert and that’s why you are in the room! Some of the biggest deciding factors in an interview are based – not only on your skills and how you’ve answered their questions – but on your body language.
- Body language dos
- Ensure a firm handshake
- Walk slowly, deliberately, and tall upon entering the room
- Maintain eye contact throughout your interview
- Look away occasionally, as not to stare, looking confidently and calmly to the right or left; never look down
- Be alert and enthusiastic
- Smile, nod, and give nonverbal feedback to the interviewer
- Body language don’ts
- Have a poor/limp handshake
- Display laziness
- Be aggressive or act in a superior, conceited or overbearing way

13. What are the top benefits that a company can gain from CMDB?
Answer: The benefits are actually realized in areas outside the CMDB itself –- and all boil down to the ability to offer better service to the business through better IT. Better change management; faster incident resolution; higher application availability; reduced asset maintenance costs; more automated processes; simpler problem resolution; increased IT governance capability … the list goes on. (company) Dumping thousands of configuration items into a CMDB won’t do any good unless there’s a clear business justification. For IT people, that might mean getting on the phone with application owners and other business managers to draw clear links between CIs and the services they support. A relevant and accurate CMDB can provide actionable data and have a positive impact on all service improvement initiatives.
14. Why do we create subgroups?
Answer: Creating subgroups allows you to customize your contact list to send messages to a targeted group of members within your system.

However, he decides to go on sabbatical for a year and wants another instructor (or perhaps, several instructors – a group), i.e. his replacement(s), to have the same role(s) (privileges) over the same set of courses. Note that the substituting instructors may belong to different user groups. The administrator can easily assign the role(s) in question to individual users or groups of users. Of course, after the tenured professor returns, the administrator can revoke those roles (privileges).
16. What is web service access only?

A user can get an elevated privilege role in his session only by manually elevating to it. The role is in the user’s session only for the duration of the session. Session timeout or log-out removes the role.
- A role that is an elevated_privilege does not appear in an assigned user’s session when the user logs in. The user must manually elevate to that role. See the following section for details.
(Requires admin or security_admin role) Presents the Activate an Elevated Privilege dialog box, which allows the administrator to select an elevated role, which will expire at the end of the session.
