QUESTION 1
Your company has a main office and three branch offices. Each office is configured as a separate Active Directory site that has its own domain controller.
You disable an account that has administrative rights.
You need to immediately replicate the disabled account information to all sites.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A. From the Active Directory Sites and Services console, configure all domain controllers
as global catalog servers.
B. From the Active Directory Sites and Services console, select the existing connection objects and force replication.
C. Use Repadmin.exe to force replication between the site connection objects.
D. Use Dsmod.exe to configure all domain controllers as global catalog servers.

Answer: B,C

Repadmin /syncall Synchronizes a specified domain controller with all of its replication partners. http://ivan.dretvic.com/2012/01/how-to-force-replication-of-domain-controllers/
How to force replication of Domain Controllers From time to time its necessary to kick off AD replication to speed up a task you may be doing, or just a good too to check the status of replication between DC’s.
Below is a command to replicate from a specified DC to all other DC’s.
Repadmin /syncall DC_name /Aped By running a repadmin /syncall with the /A(ll partitions) P(ush) e(nterprise, cross sites) d(istinguished names) parameters, you have duplicated exactly what Replmon used to do in Windows 2003, except that you did it in one step, not many.And with the benefit of seeing immediate results on how the operations are proceeding.
If I am running it on the DC itself, I don’t even have to specify the server name. http://technet.microsoft.com/en-us/library/cc776188%28v=ws.10%29.aspx Force replication over a connection
To force replication over a connection
1. Open Active Directory Sites and Services.

QUESTION 2
Your company has a branch office that is configured as a separate Active Directory site and has an Active Directory domain controller.
The Active Directory site requires a local Global Catalog server to support a new application.
You need to configure the domain controller as a Global Catalog server.
Which tool should you use?

A. The Server Manager console
B. The Active Directory Sites and Services console
C. The Dcpromo.exe utility
D. The Computer Management console
E. The Active Directory Domains and Trusts console

Answer: B

Explanation:

Answer: The Active Directory Sites and Services console http://technet.microsoft.com/en-us/library/cc781329%28v=ws.10%29.aspx Configure a domain controller as a global catalog server
To configure a domain controller as a global catalog server 1. Open Active Directory Sites and Services.
Further information: http://technet.microsoft.com/en-us/library/cc728188%28v=ws.10%29.aspx What Is the Global Catalog?
The global catalog is a distributed data repository that contains a searchable, partial representation of every object in every domain in a multidomain Active Directory Domain Services (AD DS) forest. The global catalog is stored on domain controllers that have been designated as global catalog servers and is distributed through multimaster replication. Searches that are directed to the global catalog are faster because they do not involve referrals to different domain controllers.
In addition to configuration and schema directory partition replicas, every domain controller in a forest stores a full, writable replica of a single domain directory partition. Therefore, a domain controller can locate only the objects in its domain. Locating an object in a different domain would require the user or application to provide the domain of the requested object. The global catalog provides the ability to locate objects from any domain without having to know the domain name. A global catalog server is a domain controller that, in addition to its
full, writable domain directory partition replica, also stores a partial, read-only replica of all other domain directory partitions in the forest. The additional domain directory partitions are partial because only a limited set of attributes is included for each object. By including only the attributes that are most used for searching, every object in every domain in even the largest forest can be represented in the database of a single global catalog server.
Note: A global catalog server can also store a full, writable replica of an application directory partition, but objects in application directory partitions are not replicated to the global catalog as partial, read-only directory partitions.
The global catalog is built and updated automatically by the AD DS replication system. The attributes that are replicated to the global catalog are identified in the schema as the partial attribute set (PAS) and are defined by default by Microsoft. However, to optimize searching, you can edit the schema by adding or removing attributes that are stored in the global catalog.
In Windows 2000 Server environments, any change to the PAS results in full synchronization (update of all attributes) of the global catalog. Later versions of Windows Server reduce the impact of updating the global catalog by replicating only the attributes that change.
In a single-domain forest, a global catalog server stores a full, writable replica of the domain and does not store any partial replica. A global catalog server in a single-domain forest functions in the same manner as a nonglobal-catalog server except for the processing of forest-wide searches.


QUESTION 3
Your company has an Active Directory domain. You have a two-tier PKI infrastructure that contains an offline root CA and an online issuing CA.
The Enterprise certification authority is running Windows Server 2008 R2.
You need to ensure users are able to enroll new certificates.
What should you do?

A. Renew the Certificate Revocation List (CRL) on the root CA. Copy the CRL to the CertEnroll folder on the issuing CA.
B. Renew the Certificate Revocation List (CRL) on the issuing CA, Copy the CRL to the SysternCertificates folder in the users’ profile.
C. Import the root CA certificate into the Trusted Root Certification Authorities store on all client workstations.
D. Import the issuing CA certificate into the Intermediate Certification Authorities store on all client workstations.

Answer: A

Explanation:
http://social.technet.microsoft.com/wiki/contents/articles/2900.offline-root-certification-authority-ca.aspx
Offline Root Certification Authority (CA)
A root certification authority (CA) is the top of a public key infrastructure (PKI) and generates a self-signed certificate. This means that the root CA is validating itself (self-validating). This root CA could then have subordinate CAs that effectively trust it. The subordinate CAs receive a certificate signed by the root CA, so the subordinate CAs can issue certificates that are validated by the root C
A. This establishes a CA hierarchy and trust path.
CA Compromise
If a root CA is in some way compromised (broken into, hacked, stolen, or accessed by an unauthorized or malicious person), then all of the certificates that were issued by that CA are also compromised. Since certificates are used for data protection, identification, and authorization, the compromise of a CA could compromise the security of an entire organizational network. For that reason, many organizations that run internal PKIs install their root CA offline. That is, the CA is never connected to the company network, which makes the root CA an offline root C
A. Make sure that you keep all CAs in secure areas with limited access.
To ensure the reliability of your CA infrastructure, specify that any root and non-issuing intermediate CAs must be offline. A non-issuing CA is one that is not expected to provide certificates to client computers, network devices, and so on. This minimizes the risk of the CA private keys becoming compromised, which would in turn compromise all the certificates that were issued by the CA.
How Do Offline CAs issue certificates?
Offline root CAs can issue certificates to removable media devices (e.g. floppy disk, USB drive, CD/DVD) and then physically transported to the subordinate CAs that need the certificate in order to perform their tasks. If the subordinate CA is a non-issuing intermediate that is offline, then it will also be used to generate a certificate and that certificate will be placed on removable media. Each CA receives its authorization to issue certificates from the CA directly above it in the CA hierarchy. However, you can have multiple CAs at the same level of the CA hierarchy. Issuing CAs are typically online and used to issue certificates to client computers, network
devices, mobile devices, and so on. Do not join offline CAs to an Active Directory Domain Services domain Since offline CAs should not be connected to a network, it does not make sense to join them to an Active Directory Domain Services (AD DS) domain, even with the
Offline Domain Join [This link is external to TechNet Wiki. It will open in a new window.] option introduced with Windows 7 and Windows Server 2008 R2.
Furthermore, installing an offline CA on a server that is a member of a domain can cause problems with a secure channel when you bring the CA back online after a long offline period. This is because the computer account password changes every 30 days. You can get around this by problem and better protect your CA by making it a member of a workgroup, instead of a domain. Since Enterprise CAs need to be joined to an AD DS domain, do not attempt to install an offline CA as a Windows Server Enterprise C
A. http://technet.microsoft.com/en-us/library/cc740209%28v=ws.10%29.aspx
Renewing a certification authority
A certification authority may need to be renewed for either of the following reasons: Change in the policy of certificates issued by the CA
Expiration of the CA’s issuing certificate


QUESTION 4
You have a Windows Server 2008 R2 Enterprise Root certification authority (CA).
You need to grant members of the Account Operators group the ability to only manage Basic EFS certificates.
You grant the Account Operators group the Issue and Manage Certificates permission on the CA.
Which three tasks should you perform next? (Each correct answer presents part of the solution.
Choose three.)

A. Enable the Restrict Enrollment Agents option on the CA.
B. Enable the Restrict Certificate Managers option on the CA.
C. Add the Basic EFS certificate template for the Account Operators group.
D. Grant the Account Operators group the Manage CA permission on the CA.
E. Remove all unnecessary certificate templates that are assigned to the Account Operators group.

Answer: B,C,E


QUESTION 5
Your company has an Active Directory domain.
You log on to the domain controller. The Active Directory Schema snap-in is not available in the Microsoft Management Console (MMC).
You need to access the Active Directory Schema snap-in.
What should you do?

A. Add the Active Directory Lightweight Directory Services (AD LDS) role to the domain controller by using Server Manager.
B. Log off and log on again by using an account that is a member of the Schema Administrators group.
C. Use the Ntdsutil.exe command to connect to the Schema Master operations master and open the schema for writing.
D. Register Schmmgmt.dll.

Answer: D

Explanation:
