I have passed 70-028 today at first try. I would say thanks to
www.examcheets.com and everybody participated in this
braindumps site. Don’t worry about the exam, everybody can pass
the test as long as take serious study and practice. You do not
need expensive CTEC course for passing this one.
Suggestion for exam preparation :
1) Make sure that you have experience with the common
administrative task of SQL 7
2) Browse through Books Online (BOL).
3) Take your material summary / study guide from www.brainbuzz.com.
4) Take your first practice exam from www.msexpert.com (130+
question in pool), its free
5) Take your brain dumps from this site ie
www.myresearchinstitute.com
6) Take exam simulation from this site :
www.examcheets.com
I guarantee you will pass with minimal score 900 !
OK Guys, below is my dumps as long as I remember today.
1)You are developing a security strategy for a new installation of
SQL. You want to minimize the administration required of login.
What should you do?
a) Use Windows NT Authentication Add Windows NT accounts as SQL
Server login.
b) Use Windows NT Authentication Add Windows NT groups as SQL
Server login.
c) Use SQL Server Authentication Add SQL Server login for
authorized users.
d) Use SQL Server Authentication. Add Windows NT accounts as SQL
Server login.
Answer: B Note: Ref: BOL - Index on: Windows NT groups - Topic:
Adding a Windows NT User or Group. Existing Microsoft(r) Windows
NT(r) accounts (users or groups) are granted permissions to
connect to Microsoft SQL Server(tm) before they can access a
database. If all members of a Windows NT group will be connecting
to SQL Server, you can grant permission to connect to SQL Server
for the group as a whole. Managing group permissions is much
easier than redundantly managing permissions for individual users.
If a Windows NT group should not be granted permission
collectively, you can grant permission to connect to SQL Server
for each individual Windows NT user.
2) Your domain has two SQL Server computers named SQL1 and SQL2.
Two related databases are on SQL1 and SQL2. You have standard
logins on both servers. You are able to connect to both databases
on both servers, and you are able to execute queries on both
databases on both servers. You are attempting to execute a
distributed query that joins data on SQL2 to data on SQL1. On
SQL1, you add SQL2 as a linked server. However, when you try to
execute the distributed query on SQL1, you receive a message that
your login failed. What is the most likely cause of the problem?
A. You did not execute the query on SQL2.
B. You did not map your login on SQL1 to your login on SQL2.
C. You did not use a Windows NT login for the distributed query.
D. You did not establish a direct connection to SQL2, so you are
not authenticated for the distributed query.
Answer: B Ref: BOL - Index on: mapping login information, Topic:
Security for Linked Servers. During a linked server connection
(for example, when processing a distributed query), the sending
server provides a login name and password to connect to the
receiving server on its behalf. For this connection to work,
create a login mapping between the linked servers, using
Microsoft(r) SQL Server(tm) stored procedures.
3) A user who has a SQL Server login forgot his password. How
should you restore his ability to connect to SQL Server?
A. Drop and re-create both his Windows NT account and his SQL
Server login with a new password.
B. Drop and re-create only his SQL Server login with a new
password.
C. Change his account password in Windows NT User Manager.
D. Change the password in the SQL Server Login properties dialog
box.
Answer: D, SQL server Enterprise Manager allows for easy
enterprise-wide configuration and management.
4) Maria preceded you as administrator for Microsoft Windows NT
Server and SQL Server. Maria created SQL Server logins and
passwords matching users Windows NT accounts. When user logon to
the Windows NT Server domain they obtain access to the SQL Server.
Which permissions do users receive to access SQL Server by using a
trusted connection?
a) Only the same permissions as those that are granted to their
SQL Server login
b) Only the same permissions as those that are granted to their
Windows NT account
c) The cumulative permissions that are granted to their SQL Server
login and their Windows NT account
d) Only the permissions that are granted in common to their SQL
Server login and their Windows NT account
Answer: B Note: The NT accounts and the SQL are different entities
and mutually exclusive, it is one or the other. Trusted connection
is NT Authentication that is why NT Accounts.
5) You plan to give users in the Windows NT Sales group limited
access to the Sales and Inventory databases. All access for data
modifications and reporting will be through a Microsoft Excel
Application. How should you set up access for the Sales group in
both databases?
a) Create a single application role. Grant the Sales group
permissions on that role in each database.
b) b) Create an application role for each database. Grant the
Sales group permissions in each database.
c) c) Create a single application role, and grant it permissions
in each database.
d) d) Create an application role in each database, and grant it
the appropriate permissions.
Answer: D Ref: BOL - Index on: applications, roles, (Topic:
Application Security and Application Roles) Application roles
contain no members. Users, Microsoft Windows NT(r) groups, and
roles cannot be added to application roles; the permissions of the
application role are gained when the application role is activated
for the user's connection through a specific application(s). A
user's association with an application role is due to being
capable of running an application that activates the role, rather
than being a member of the role. It is necessary for a connection
to lose default permissions applied to the login/user account or
other groups or database roles in all databases for the duration
of the connection and gain the permissions associated with the
application role to ensure that all the functions of the
application can be performed. For example, if a user is usually
denied access to a table that the application must access, then
the denied access should be revoked for the user to successfully
use the application. Application roles overcome any conflicts with
user's default permissions by temporarily suspending the user's
default permissions and assigning them only the permissions of the
application role.
