Q

One To Many relationship -

A

On an incident record, when you go to related records, there is a problem field. The reference to a problem record creates a one to many relationship, because several incidents may relate to that problem. From an incident we can’t indicate more than one problem for example.

A

When a parent table becomes the parent of a child table, that child table inherits all of the database structure (Columns, but none of the rows)

Q

What colors are on the Schema Map? (THIS IS ON THE TEST)

A

Subject Table - Highlighted in Yellow
Blue Bars - Extend the subject table Further down the line (IE: Unix Servers would also have AIX, HPUX, etc.)
Red Bars - are referenced by the subject table
Green Bars - Extended Tables (all the way back to the base table) (IE: Unix Table would extend the CMDB, CMDB_CI, CMDB_CI_HW, CMDB_CI_COMPUTE)

Q

Access control is set at the….

A

Row and Column Level

28
Q

Security rules can restrict your ability to view or run reports on a specific table (T/F)

A

True

29
Q

When you become a security admin by elevating roles…

A

You need to log out before you lose those privilages

30
Q

Access control rule specifies

A

Operations
Objects
Permissions

31
Q

Permissions include

A

Roles
Conditional Expression
Scripts

32
Q

Three Security Modules used by Sys Admin

A

Security
Access Control (ACL)
High Security Settings

33
Q

When you create a custom table servicenow creates access control rules by default (T/F)

A

True - CRWD

34
Q

When no specific ACL rule is defined then…

A

The rule applies to the whole table including all records

35
Q

table.field ACL would define…

A

Rules applying to only one field in a record

36
Q

table.*

A

This rule would apply to every field where there isn’t already a table.field rule

37
Q

Table.none rule is the least specific rule, followed by table.field, and then table.*

A
38
Q

By Default when a read access control has been established for a new table…

A

then assume there is complete access to all fields and rows on the table

39
Q

ServiceNow starts from Generic to Specific security Policies (T/F)

A

False - ServiceNow goes from specific to general as they review security policies

40
Q

A user must pass which rules to access a record object

A

Table First
Field ACL rule second

41
Q

Record ACL rules are processed in the following order:

A

Match the object against table ACL Rules (Specific to general)
Match the object against Field ACL Rules (Specific to General)

42
Q

If a user passes table ACL rules and not Field ACL rules, can they access a record object?

A

No, both rules must be passed in order to access the table

43
Q

Should you grant a new role to an individual, or to a group for inheriting those roles?

A

Group is the best practice, it would be best to add a permission or ACL to a group, and then assign a user to that group

44
Q

What are import sets?

A

Import set is a tool used to import data from various data sources, and map that data into ServiceNow tables

45
Q

Import Set Tables are defined as….

A

A staging table prior to the transform label and pushing to a target table within the ServiceNow instance

46
Q

A transform map is…

A

a set of field maps that define the relationships between fields in an import set table and fields in a target table

47
Q

Coalesce field is…

A

A field or multiple fields that will be used as unique keys, the coalesce will override instead of update where there is a match

48
Q

IF you don’t do coalescence, what will happen?

A

Data will just be treated as brand new records, and SN won’t look for a match. HUGE TABLES could result

49
Q

Which roles can import data?

A

admin
import_admin

50
Q

Data Source Imports can be accomplished through

A

Local Source (XML, CSV, Excel)
Network Servers (LDAP), or JDBC

51
Q

What are the three main sources of data for import sets?

A

Local Data (excel, flat file)
Network (LDAP)
Java Database Connectivity (JDBC)

Configuration Item (cmdb_ci)
CI Relationship (cmdb_rel_ci)

53
Q

4 “parts” of the ITSM platform related to the CMDB

A

Incident Management
Change Management
Problem Management
Request Management

54
Q

What are the benefits of an accurate and up to date CMDB?

A

Locate failed changes and associated INCIDENTS
Facilitate impact analysis of proposed CHANGES to reduce downtime
Assess PROBLEMS pertaining to specific CIs
Efficiently manage INCIDENTS affecting CIs and Services

55
Q

What are the three elements of the CMDB Workspace

CI Search
CMDB Health
CI Overview
CIs managed by me

56
Q

The strength of the dependency view are the…

A

relationships here, which are based off of records on a table

57
Q

Common Service Data Model is NOT

A

A process or implementation guide
Not a set of reports
not code
not a sku or product to buy
not an automatic fix for broken implementations

58
Q

CSDM Is…

A

Standard Terms
Best Practices
out of the box CMDB Core Tables

59
Q

ServiceNow Discovery….

A

scans the network to inventory devices and applications to update the CMDB

60
Q

61
Q

Which module can you use to create a new table?

A

Tables
Tables & Columns

62
Q

Which elevated role is required to modify access control rules?

A

63
Q

64
Q

A parent class that is not an extension of another table is called

A

Base Table

65
Q

In what order are access controls evaluated
