Multiple server WSUS architecture assume remote sites are well connected. However some sites have relatively low-bandwidth connections. In cases like these it is best to limit updates (usually critical). A
Answer
WSUS server limits to critical updates being transferred to remote servers. (answer does not include spaces)
low-bandwidth
In the simplest configuration, a
Answer
WSUS server downloads updates from the Microsoft Update Site.
single
Select from the following, all of the problems associated with non-centralised updates. Select one or more: a. Efficient bandwidth use b. Heavy bandwidth utilisation c. Compliance d. Update approval e. Centralised reports
b. Heavy bandwidth utilisation
(Each O.S. is performing separate updates, which of course uses more network bandwidth.)
c. Compliance
(Default windows update settings provide no means for feedback to administrators.)
d. Update approval
(Each user on each computer must approve updates individually.)
In a basic configuration a single WSUS server can support how many clients? Select one: a. 25,000 b. 5,000 c. 10,000 d. 1,000 e. 50,000
25,000
Where would the administrator configure WSUS automatic updates easiest? Select one: a. Registry editor b. Using a GPO (Group policy) c. On each individual PC. d. On the server "Control panel"
Using a GPO (Group policy)
This question tests knowledge of where you would use WSUS and where you would not.
Match the following 2 statements with the correct answer:
Mobile workstations?
Small offices?
Mobile workstations – would not have access to a dedicated update server most of the time
Small offices – don’t really benefit as time configuring is greater than manual effort
The
Answer
WSUS server architecture is the same as a replica or autonomous server, except that instead of central servers transmitting updates directly to the downstream servers, administrators save updates to a shared medium.
disconnected
Match the following terms with the correct response.
An upstream WSUS server is:
A downstream WSUS server is:
An upstream WSUS server is: – where updates originate and are distributed.
A downstream WSUS server is: – a server that acquires updates and passes them to clients.
WSUS servers, function in much the same way as replica WSUS servers, except that remote administrators at each site are responsible for evaluating & approving updates.
Autonomous
In a
Answer
WSUS server configuration, one central WSUS server downloads updates from the Microsoft update website. Approved updates filter down to additional downstream servers. This model minimises internet traffic, offloading transmissions to the LAN instead.
replica
