Q

When returning a large dataset with N/search:

If a record that originally fit the search criteria is updated and no longer fits the criteria, what happens?

A

It is skipped by the search.

In this case, some records that were originally included in the search results may not be returned, and the total number of returned records may be smaller than the original total number of results.

Q

When returning a large dataset with N/search:

If new records are created that fit the search criteria, what happens?

A

They are also returned.

The total number of returned records may be higher after you page through the results than the original total number of results, and duplicate results may be returned.

Q

When returning a large dataset with N/search:

If a record from the first results page is updated and it no longer fits the criteria when going through subsequent pages of search results, what could be a concern?

A

Results may be missing.

For example, if a record from the first results page is updated and it no longer fits the criteria, another record now fits into page one. However, because earlier pages are skipped when going through subsequent pages of search results, this record is not returned.

Q

If new records of the same type, matching the search criteria, are created between a search request and a searchMoreWithId request, what problem could occur?

A

It can cause position changes in the results and can move records on or even out of search pages. This causes missing or duplicate records on pages.

Q

To avoid issues when returning a large dataset with N/search:

How should we define our search criteria, to avoid using a loosely defined search that returns a large data set, and why?

A

Make your search criteria as specific as possible.

With more specific criteria, the result set is smaller and there is less chance that records fitting the search criteria are created or updated as you go through the pages of the result set.

Q

How does the SuiteQL technology improve security?

A

Role-based restrictions still apply, and it does not allow unsupported SQL functions, helping to prevent SQL injection attacks.

46
Q

What is a syntactic limitation to the SuiteQL platform?

A

SQL-92 or Oracle SQL syntaxes CAN be used, but only one may be used per query.

47
Q

When using SuiteQL, the character cases of record type and field names may not always be consistent and can change. These name changes may occur after a NetSuite release or scheduled e-fix.

How can we address this?

A

Convert these names to upper or lower case to ensure consistency

48
Q

True or False?

N/cache can be used in ALL script types.

A

70
Q

If the Concurrency Limit field in the script deployment of a Map/Reduce script is left empty, how many jobs will be assigned to the Map and Reduce stages of the script?

A

The number of jobs created will be equal to the total number of processors available in the account

71
Q

Dependent tasks are processed using SuiteCloud Processors, why is this?

A

Because dependent tasks are only capable of being scheduled scripts, or map/reduces

72
Q

A

Only 5

75
Q

True or False?

The more SuiteCloud Plus Licenses you have for your account, the larger the number of queues available for CSV imports.

A

False.

The number of SuiteCloud licences does not affect the number of queues available for CSV imports

76
Q

82
Q

Regarding Integration Concurrency for RESTlets:

What setting sets the maximum number of concurrent requests for integrations?

A

The Integration Concurrency Limit

83
Q

Regarding Integration Concurrency for RESTlets:

A concurrency limit can be allocated to individual integration records.

However, there is a minimum unallocated concurrency limit value (a minimum amount of concurrency that is not allocated to any one integration) which is reserved for integrations that do not use an integration record or for creating a new integration.

What is the minimum unallocated concurrency limit value?

A

The minimum unallocated concurrency limit is 1, so if your concurrency limit is 5, you can only allocate a concurrency limit of 4 to your integrations.

Leaving 1 free for integrations without an integration record, or for creating a new integration.

84
Q

What setting determines if a Suitelet can be navigated to by both external and internal users?

A

The “Available Without Login” checkbox setting.

85
Q

A

The “All Roles” checkbox.

87
Q

There are 2 security measures that are self explanatory, and should absolutely be upheld at all times.

The flip side of this card will list them.

A

Do not hard code any passwords.

Always encrypt user credentials, use Token Based Authentication or OAuth2.0 when possible

88
Q

There are 4 field ID’s that cannot be read in beforeSubmit for any external role users. (e.g., Shoppers, Online form users, anonymous users, customer centre users, etc.)

What are they, and why?

A

◦ password
◦ password2
◦ ccunumber
◦ ccsecuritycode

Because these fields obviously contain sensitive information (passwords and credit card numbers)

89
Q

Why do we need to take caution when using the N/auth module to change user credentials?

A

Because it allows you to include a plaintext string for the password

90
Q

When using the N/query module to retrieve credit card information, what version of the credit card number can be retrieved, and ONLY that version?

A

Only the encrypted version of the credit card number can be retrieved.
