Use HTTPS websites only

Question 5

During a Scrum sprint review, stakeholders request a new feature that was not in the product backlog. The product owner wants to add it to the next sprint. What is the correct action according to Scrum?

Add the feature to the current sprint immediately

Question 6

A company wants to secure its wireless network. Which of the following is the BEST practice?

Accepted Answer

Change the default administrator password. Changing the default administrator password is the best practice because default credentials are widely known and easily exploited, providing an attacker with full administrative access to the wireless access point or router. This action directly mitigates unauthorized configuration changes, which is a fundamental security measure. In contrast, the other options either weaken security or have no significant protective effect.

Answer

Broadcast the SSID

Answer

Disable MAC filtering

Answer

Use WEP encryption

Question 9

Refer to the exhibit. A user attempts to insert a row into Orders with a CustomerID that does not exist in the Customers table. What is the expected outcome?

Accepted Answer

The INSERT statement fails with a constraint violation. The INSERT statement fails with a constraint violation because the CustomerID column in the Orders table is defined as a foreign key referencing the CustomerID primary key in the Customers table. When a user attempts to insert a row with a CustomerID that does not exist in the Customers table, the relational database management system (RDBMS) enforces referential integrity and rejects the operation, raising a foreign key constraint violation error.

Answer

The row is inserted but with a warning

Answer

The row is inserted successfully

Answer

The Customers table automatically creates a new customer

Question 10

Which of the following is a benefit of using a database instead of a flat file?

Accepted Answer

Support for concurrent multi-user access. Databases provide concurrent access control, allowing multiple users to read/write data simultaneously without corruption.

Simpler setup and configuration

Answer

Faster file transfer speeds

Answer

Lower storage requirements
