Question

Windows administration answer this question for computer network

1. To provide support to Active Directory, suggest your DNS strategy:

Active Directory is dependent on DNS as a domain controller location mechanism and uses DNS domain naming conventions in the architecture of Active Directory domains. There are three components in the dependency of Active Directory on DNS:

• Domain controller locator (Locator)
• Active Directory domain names in DNS ● Active Directory DNS objects

Internal DNS
External DNS

1) What is the advantage of the global catalogs?

2) Recommendation of quantity to be implemented?

3) Recommendation of location to be implemented?

Answer 1

1.) A global catalog is automatically created when you install the first domain controller in the root domain of a new forest. When you have multiple domains in the forest, the global catalog provides users a way of finding the resources within other domains. The global catalog also provides universal group membership information in processing logons so that a user's credentials can be accurately determined. Its Advantages are:

• its advantage is realized when you have multiple domains in the forest because it ensures that users within any domain can query the network for resources, regardless of where those resources are located.
• The global catalog indexes information, which is configurable by the administrator so that only crucial data is included.
• When you have a global catalog server in a local site, logons and network queries are faster.

Note: Assuming that 2nd & 3rd questions were asked for Global Catalogs as its not explicitly mentioned.

2.) If you determine that the total number of users in your forest is less than the maximum number of users that your domain can contain, you can use a single domain. Be sure to accommodate for planned future growth when you make this determination. If you determine that the total number of users in your forest is greater than the maximum number of users that your domain can contain, you need to reserve a higher percentage of bandwidth for replication, increase your link speed, or divide your organization into regional domains.

3.) Global Catalog location can be:

• Please ensure that each site must have at least one Global Catalog (GC).
• You can also make all your DCs (Domain Controller) act as a GC.
• Replicate additional attributes to GCs, if required.
