Ppt on advantages of frequency domain over time domain representation?

with the help of laplace transform the calculation part can be reduced in frequency domain .In time domain differential equations are used and solution is cumbersome.

What intersite replication uses what kind of traffic to reduce the impact to bandwidth on corporate WAN links?

Active Directory replication uses compressed and encrypted traffic to reduce the impact on corporate WAN links. This helps in minimizing bandwidth usage and ensuring efficient communication between domain controllers.

Suppose a VPN server has multiple network cards from which network interface is an IP address assigned?

Each NIC will have it's own IP address for each network it's connected to. so a machine with 3 network cards has at least 3 IPs (one NIC can have multiple IPs if configured that way, you can also tell a NIC to not acquire an IP, but that's kind of uncommon) the VPN server could be configured to only listen on one network interface or all of them. Also the IP addresses assigned to the clients should route them on the NIC with matching IP/netmask, but that can also be configured. you probably want to use a static IP for the interfaces to your VPN server and configure it to only use the network interfaces that you want it to.

What is another name for virtual servers?

Other possible names for a virtual server would be network server, name based hosts, or the most common...just 'server' on it own. Your IP address is assigned depending on what server you use.

What are requirement to install ad on a new server?

· An NTFS partition with enough free space (250MB minimum)

· An Administrator's username and password

· The correct operating system version

· A NIC

· Properly configured TCP/IP (IP address, subnet mask and - optional - default gateway)

· A network connection (to a hub or to another computer via a crossover cable)

· An operational DNS server (which can be installed on the DC itself)

· A Domain name that you want to use

· The Windows 2000 or Windows Server 2003 CD media (or at least the i386 folder)

What are the demerits of firewalls?

  • No firewall provides protection against viruses, continuously new viruses and new methods are released everyday which affect the system.
  • Firewall can't give protection against all attacks which don't pass through firewall.
  • Firewall reflects overall security level of network, an architecture which depends on one security mechanism or one method has a point of failure which may open the system to intruders.
  • If firewall is incorrectly configured it can't tell you the problem, only professional want to minimize the risk using their experience.
  • It is highly difficult for firewall if someone hacked into your network to notify you, for which you need separate monitoring tools.
  • If a hacker masquerades like trusted user or employee it is highly impossible for firewall to protect from such type of hackers, because today we have numbers of ways to find user names and passwords.
  • Firewall can't protect system from malicious codes also.
  • Firewalls don't encrypt e-mail messages or confidential documents which are sent inside the organization or outside of the organization.
  • Firewalls can't give 100% security to the system or organization.
  • Firewall can't find other vulnerabilities which might allow hacker to access internal network.
  • Firewall cannot decide which is legitimate decision and which is not, it works entirely based on the set of rules and criteria and policy mentioned by the management part during the planning of security policy.

Where the global catalog available?

The global catalog contains a complete replica of all objects in Active Directory for its Host domain, and contains a partial replica of all objects in Active Directory for every other domain in the forest. 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 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 Windows 2000 Server or Windows Server 2003 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.

What is a stale dhcp certificate?

DHCP is used to assign IP addresses to computers joining a network. Many ISPs use DHCP to give their customers IP addresses. When DHCP assigns you an IP address, or sends you a "DHCP certificate," it "leases" the IP address to you for a period of time. When this lease runs out, the DHCP certificate becomes "stale," and you must request a new one. Usually your computer will do this automatically and you won't even know it happened. This terminology is a bit strange. I can guess what you mean by a "stale" DHCP "certificate" but I'm not sure that everyone would. It sounds like something that someone made up. I could be wrong. -DJ Craig

What happens if primary domain controller fails?

You wont be able to access the network resources/login properly to your account.

Who is server for dhcp?

It is what... DHCP is designed to automatically distributed IP addresses to connected to the same network devices.

What type of groups would you use when configuring distribution groups in a multiple domain forest?

Use Universal distribution groups in a multiple-domain environment. The membership of universal distribution groups is replicated to each global catalog server in each domain
