Which statement is true about Enterprise Manager (EM) express in Oracle Database 12c?
A.
By default, EM express is available for a database after database creation.
B.
You can use EM express to manage multiple databases running on the same server.
C.
You can perform basic administrative tasks for pluggable databases by using the EM express
interface.
D.
You cannot start up or shut down a database Instance by using EM express.
E.
You can create and configure pluggable databases by using EM express.
Explanation:
Note:
* Oracle Enterprise Manager Database Express (EM Express) is a web-based database
management tool that is built inside the Oracle Database. It supports key performance
management and basic database administration functions. From an architectural perspective, EM
Express has no mid-tier or middleware components, ensuring that its overhead on the database
server is negligible.
Incorrect:
Not B: For one database at a time.
Not C, Not E: Enterprise Manager Database Express features can be used against non-CDBs or
Oracle RAC database instances.
Not D: After the installation, your instance is started and your database is open. In the future, there
will be times, perhaps for doing database maintenance or because of a power or media failure,
that you shut down your database instance and later restart it.
The ans D is good. For A read Be default EM Express is configured for the traditional (non-CDB) or container (CDB) database if selected when using the DBC
Agree with noori. D is the correct ans.
D is correct, but C as well, as long as you configure different port
Not A
From the Oracle® Database 2 Day DBA 12c Release 1 (12.1)
You can use EM Express to manage a non-CDB, a CDB, or a PDB. For each non-CDB, CDB, or PDB that you want to manage using EM Express on a given host, a unique HTTPS port must be configured. A different port must be configured for each container in a CDB that you want to manage using EM Express.
The given answer, A is wrong in the sense that it is not the only statement which is true. A is correct because EM Database Express is available after database creation. The option B is badly worded. Technically speaking, B is true in the sense that you can use EM Database Express to manage multiple databases running on the same server. It just wouldn’t be the same instance of EM Database Express for all databases because each database would have their own instance of EM Database Express operating on a unique HTTP or HTTPS port. C is correct. You can configure an HTTP or HTTPS port for each PDB using DBMS_XDB_CONFIG and log into EM Database Express using that port. D is also correct because you cannot startup/shutdown instances via EM Database Express. E is not true. The creation and configuration of PDBs is limited to OUI, DBCA or SQL*Plus (and SQL Developer). So, true statement are A, B (sort of), C and D.
H*T*H
Enterprise Manager Database Express is available only when the
database is open. SoEnterprise Manager Database Express cannot be used to
start up the database. Other operations that require that the database change state, such as
enable or disable ARCHIVELOG mode, are also not available in Enterprise Manager Database
Express.
D ?
The options in exam that i chose which is correct are:
a. You cannot start up or shut down a database.
b. Multiple databases on the same node may each be individually manged.
(Note the b. answer i started here is what you find in the exam. In stead of A,E)
Total questions in Exam are 85. There are 2 sections.
51 questions for section 1(New Features for DBA).
And 34 questions for section 2(Key DBA Skills).
All questions do not have equal marks.
I passed the exams last week with 73% & 71%.
All questions are from this dump but the answers in the exam are randomized (changed). Study answers carefully, and use comments here to guide your answer choice. Just a few answers here are wrong. Saw additional 4-5 questions in exam. Section 1 has a lot of questions on pluggable DB and Container DB. Do not just memorize this dump. Run the installation and practice plugging & unplugging a DB.
Wish you all the best.
