- List five security features of IPSec.
ANS:
The features include:
Authentication using digital signature to identify the sender
Integrity through the use of hash algorithms, ensuring that the data has not been altered
Privacy through encryption that protects the data from being read
Anti-replay, which prevents unauthorized access by an attacker who resends packets
Nonrepudiation through the use of public-key digital signatures that prove the message’s origin
Dynamic rekeying that allows keys to be generated during communication so that the different transmissions are protected with different keys
Key generation using the Diffie-Hillman key agreement algorithm, which allows computers to agree on a key without having to expose it
Key lengths that are configurable to allow for export restrictions or highly sensitive transmissions

PTS: 1 REF: 391
- List three factors to be considered when designing your DHCP network.
ANS:
Factors to be considered:
Draw yourself a map of your network. Make sure you show each physical and logical subnet and the routers between the various subnets.
If the network uses routers to subnet the network, do the routers support forwarding DHCP broadcasts? Most new routers do, but that option must be turned on.
Sectioning the IP address range between two servers will provide fault tolerance.
Depending on the speed and reliability of your network and the links between your subnets, the routers can be configured to forward DCHP broadcasts (or you could add a DMCP relay agent).
If you are planning to the DHCP server to update DNS records for legacy clients, do not run the DHCP service on a domain controller. Doing so would cerate a security risk.
Remember that the recommendation is that a single DHCP server can provide services for 10,000 or fewer clients and 1000 or fewer scopes; therefore, make sure you size your servers appropriately.
DHCP servers access their disk drives very frequently. Make sure you use either a disk drive with a fast access time or a hardware RAID disk controller.
If you are still using any Windows NT 4 domain controllers, make sure you have them upgraded to Windows Server 2003.
PTS: 1 REF: 430-431

The amount of time the lease duration should be for the IP addresses leased from this scope

Whether you need to reserve specific IP addresses for specific clients
