MCSE 70-291: Microsoft 70 291 Practice Questions

The correct command for clearing the DNS name cache on the client side is Ipconfig/flushdns

HOSTS and LMHOSTS are files and not services. WINS resolves NetBIOS names and not host names. DNS is the dedicated service for resolving host names.

An Active Directory--integrated DNS zone uses Active Directory for permitting secure dynamic updates.

A DNS query is a request the DNS client resolver makes to a DNS server to obtain the IP address of either a flat or a hierarchical host name.

The DNS server in the Windows Server 2003 environment is capable of incremental zone transfer.

NetBIOS is a naming scheme or a service that is proprietary to Microsoft and limited to LANs only. It cannot be used for routing.

In an Active Directory environment a DHCP server cannot initialize without authorization from ADS

VPN uses tunneling protocols and encryption protocols that allow secure information to be transmitted through public networks.

The property of the subnet mask is to differentiate or highlight the network portion and mask the host portion of an Ip address.

The Master DNS could be any DNS server on the network that has a read-write copy of a zone that has been created on it and is capable of sending notifications for those updates to the secondary servers.

UNIX based DHCP servers co-exist with Windows based DHCP servers in the Active Directory environment.

To exclude a set of IP addresses from being assigned to clients on the network, you must use the exclusion range property.

You can create a console for your own convenience through the Microsoft Management Console or use the regular IP Security Console through the MMC.

The Event Viewer tool helps you to review the auditing information of all servers on the network

Performance counters such as memory, processor, network, and disk use standard network service counters for monitoring the performance of network access servers.

RAS (Remote Access Service) when configured is responsible for accepting dial-in connections on a Microsoft network

TTL is set for any Active Directory integrated zone

A hop count is a significant factor when the DHCP server and the client are separated by subnets.

As the name suggests the reverse lookup zone provides an Ip to name resolution

Any database that is subject to dynamic changes should be maintained as per schedule to avoid database inconsistencies.

The first DHCP Renewal is raised by the client after 50% of the lease has expired.

When the DHCP is declining a clients renewal request, it informs so with the help of a negative acknowledgement.

Certificates are meant to authenticate end users or computers in a communication session as well as encrypt the data is required.

PTR records and acts as a proxy for downward compatible clients of DNS

The secondary zone stores a read-only copy of an existing zone to help balance the load of the primary servers and provide backup.

Small networks still work efficiently with static or manual updates rather than dynamic environment.

DHCP can dynamically update resource records in DNS during a clients DHCP IP configuration process.

RADIUS is a very extensive service that is used to secure remote or dial-in connection with the local network.

Internet Authentication Service uses RADIUS technology and is very popularly usedon the Microsoft networks.

Routing interface can be a physical interface (Ethernet or Serial) that interfaces Layer 2 of the LAN to the router. It can also be a logical interface that can be administratively created during the process of configuration.

The vendor-class option is used by a DHCP server to identify the vendor type and hardware configuration options of a client during the lease process.

Using 802.1.X-enabled LAN switches or wireless Access Points (WAP) for connecting to the network ensures that the client credentials are authenticated before the DHCP server assigns a lease to them.

Jetpack is a compacting tool and not a backup tool

Nbtstat -R command can be used to purge and reload the remote cache name table.

A DNS resource record that points to the parent level is known as a root hint.

Secure dynamic update is the process by which a dynamic update happens under the security of the ADS

To implement smart cards you need to configure EAP-TLS

Routing protocol is a set of common rules agreed by a group of routers and can understand network addresses

System Monitor enables you to gather performance real time data of specific network components.

As the name suggests IPSec is meant for security of IP based networks only.

Within the scope options you must choose the router property and assign the IP address of the local interface of the router for that network.

A secondary server can pull its updates from the primary server only after it receives a notification from the Primary or the Master server stating that there are updates to be taken.

The Compatws.inf security template allows applications that are not Windows 2003 applications to run successfully on a Windows Server 2003 computer.

Secure updates are possible only if the zones is integrated with Active Directory.

PPP (Point-To-Point) protocol is the dial-up protocol used in Microsoft networks.

The DHCP server sends the lease period to the client along with the acknowledgement.

Best way to be sure that communication has not halted due to connectivity issues, is to check the connectivity without any policies in place and using clear text passwords.

PAP uses clear text, CHAP uses two-way handshake

DHCP relay agents can also be configured to communicate with the DHCP server in the Unicast mode.

In situations where a local DHCP has failed and a remote one has to be accessed, before transmitting a packet to a remote DHCP server, the DHCP relay agent waits for a few seconds. This period is known as boot threshold.
