C. A data file can belong to only one tablespace.
D. A data file can have only one segment created in it.
E. A data block can spread across multiple data files as it can consist of multiple operating system (OS)

What user name and password are used to log in to the administration interface to configure the appliance?
A. The initial user name and password must be supplied on the first login attempt.
B. The initial user name and password must be supplied during deployment.

A user has a perimeter firewall and up-to-date antivirus software. The user is asking what else they can do to improve their security. Which of the following will have the MOST impact on network security? (Select TWO).
A. Install additional antivirus software
B. Disable screen savers
C. Conduct a daily security audit
D. Assign security rights based on job roles
E. Use strong passwords
To improve security, assign security rights based on job roles. You need to give least amount of privilege to users so that they can do their jobs without having access to resources that have nothing to do with their job roles.
Small form factor PCs that utilize full-height PCI and PCI-Express cards need which of the following supplementary items to allow for proper installation?
A. FireWire cards
B. Riser cards
C. Storage cards
D. Network cards
Evaluate the following CREATE TABLE commands:
CREATE TABLE orders
(ord_no NUMBER(2) CONSTRAINT ord_pk PRIMARY KEY,
CREATE TABLE ord_items
qty NUMBER(3) CHECK (qty BETWEEN 100 AND 200),
expiry_date date CHECK (expiry_date > SYSDATE),
CONSTRAINT it_pk PRIMARY KEY (ord_no,item_no),
CONSTRAINT ord_fk FOREIGN KEY(ord_no) REFERENCES orders(ord_no));
The above command fails when executed. What could be the reason?
A. SYSDATE cannot be used with the CHECK constraint.
B. The BETWEEN clause cannot be used for the CHECK constraint.
C. The CHECK constraint cannot be placed on columns having the DATE data type.
D. ORD_NO and ITEM_NO cannot be used as a composite primary key because ORD_NO is also
the FOREIGN KEY.
The CHECK constraint defines a condition that each row must satisfy. The condition can use the same constructs as the query conditions, with the following exceptions:
References to the CURRVAL, NEXTVAL, LEVEL, and ROWNUM pseudocolumns Calls to SYSDATE, UID, USER, and USERENV functions
Queries that refer to other values in other rows
A single column can have multiple CHECK constraints that refer to the column in its definition. There is no limit to the number of CHECK constraints that you can define on a column. CHECK constraints can be defined at the column level or table level.
CREATE TABLE employees
salary NUMBER(8,2) CONSTRAINT emp_salary_min
CHECK (salary > 0),
Which of the following protocols operates at the HIGHEST level of the OSI model?
An administrator has a network subnet dedicated to a group of users. Due to concerns regarding data and network security, the administrator desires to provide network access for this group only. Which of the following would BEST address this desire?
A. Install a proxy server between the users’ computers and the switch to filter inbound network traffic.
B. Block commonly used ports and forward them to higher and unused port numbers.
C. Configure the switch to allow only traffic from computers based upon their physical address.
D. Install host-based intrusion detection software to monitor incoming DHCP Discover requests.

What should the architect consider to increase the security of the current authentication solution?
A. Adding a second authentication factor
