Apple Certifications Exam 9L0-509

2008-09-18T03:08:00.000-07:00

In practice the 9L0-509 distinction between the two pieces of equipment is really a matter of function rather than any real difference. As mentioned earlier, modems and serial communication equipment have been mixed together, this is another case of that. In this situation, the modem can be thought of as the Data Communications Equipment (DCE) and 9L0-402 Questions the terminal that somebody is sitting down and using is the Data Terminal Equipment. In the older days when it was common to use a timeshare computer system (pre 1980s), you would dial up a telephone, stick the handset that you would normally talk with into an acoustical modem, and that modem would be 9L0-509 connected to a simple dumb terminal with an RS-232 cable. When we get to baud rates this will make more sense, but the typical connection speed was usually either 50 baud or 110 baud, and really fast connections going at 300 baud.

As a side note, when the very first IMP's (Interconnection Message Processors) that formed the first nodes/routers Apple 9L0-402 of ARPAnet (the ancient predecessor of the internet), this was exactly the connection system they were using. This later gave way to other communication systems, but this was the beginning of the internet.

The RS-232 standard 70-270 is a collection of connection standards between different pieces of equipment. This is a rather old standard, and has been revised many times over the years to accommodate changes to communications technology. A bare-bones 70-284 connection will have only one wire connected between two pieces of equipment, but usually there is more. Three wires (transmit, receive, and ground) are usually the minimum recommended. A fully implemented RS-232 connection can have as many as 25 wires between each end. Some of the early RS-232 connections 70-291 were also used to connect terminal equipment to modems, so information about modems is sometimes found with general serial data communication.

support this speed is Cat3 cable, which is rated at up to 16 Mbps while Cat2 cable is rated
at up to 4 Mbps only.

Incorrect Answers:

You need to design an access control strategy for the Willow Bridge, Ltd. internal
DNS zone file. Take care in your solution to meet the requirements.

What should you do?

A. Enable secure dynamic updates on the willowbridge.com zone.
B. Enable secure dynamic updates on the local.willowbridge.com zone.
C. Convert local.willowbridge.com to an Active Directory-integrated zone then enable
secure dynamic updates for the zone.
D. Convert willowbridge.com to an Active Directory-integrated zone then enable secure
dynamic updates for the zone.
Answer: C
Explanation: You need to convert local.willowbridge.com to an Active
Directory-integrated zone then enable secure dynamic updates for the zone.350-001 Active
Directory-integrated zone files are stored in the Active Directory database and are
replicated during normal directory replication. It will also allow for secure dynamic
updates by restricting DNS zone dynamic updates only to computers that are
authenticated and joined to the Active Directory domain where the DNS server is located.
It will thus prevent unauthenticated computers from creating source records.
1. DNS1 is used to provide host name resolution services for the internal network clients
and will host the standard primary zone local.640-802 willowbridge.com.DNS1 is located on the
internal network in the Chicago office.
2. We need to ensure that both DNS1 and DNS2 are protected against this accidental
modification

You first need to convert the zone to an Active Directory-integrated zone. Because at
this stage the local.willowbridge.com zone is a primary DNS zone, which will not allow
for support for secure Dynamic DNS (SDDNS).VCP-310 Besides you should not allow externally
available zones to be stored in the Active Directory or configured to support dynamic
updates.
B: You first need to convert the zone to an Active Directory-integrated zone. Because at
this stage the local.willowbridge.com zone is a primary DNS zone, which will not allow
for support for secure Dynamic DNS (SDDNS).
D: The internal DNS zone is hosted by the DNS1 server which is located on the
local.willowbridge.com zone and not willowbridge.com.
