How should a RAS server be configured to restrict remote TCP/IP users to the RAS server's resources only?
|
uncheck the "Enable IP Routing" option
|
|
What three types of routes can routing tables contain?
|
network routes, host routes, and the default route
|
|
What are the two operation modes for RIP?
|
periodic update mode, and auto-static mode
|
|
What RIP operation mode is the default?
|
periodic update mode
|
|
What is a RIP route?
|
a dynamic route (disappears when the router is stopped)
|
|
How are routes received from other routers marked while RIP is in periodic update mode?
|
as RIP routes
|
|
Why is RIP's periodic update mode not appropriate for demand-dial connections?
|
the router will bring up the connection every time it needs to broadcast its routing table
|
|
When does RIP broadcast its routing table when in auto-static mode?
|
only when a remote router asks for it
|
|
How are routes received from other routers marked when RIP is in auto-static mode?
|
as static routes (persistent)
|
|
What RIP mode do demand-dial interfaces default to?
|
auto-static mode
|
|
What is an OSPF area?
|
a collection of interconnected networks
|
|
What network component connects OSPF areas?
|
backbones
|
|
What are routers that link OSPF areas together called?
|
area border routers
|
|
By default, does RRAS prefer static or dynamic addresses?
|
static addresses
|
|
What tool is used to install RIP and OSPF?
|
the RRAS console
|
|
In OSPF, what are virtual links used for?
|
connecting backbone area border routers to non-backbone area border routers
|
|
Is OSPF capable of screening out individual routes?
|
yes
|
|
Is RIP capable of screening out individual routes?
|
yes
|
|
What command is used to manually add static routes?
|
route add
|
|
What is Silent RIP?
|
RIP mode where a router listens for updates but does not advertise its own
|
|
What is Silent RIP often used for?
|
connecting small networks
|
|
Where is a HOSTS file stored?
|
%systemroot%\system32\drivers\etc
|
|
What does split-horizon processing do?
|
tells a RIP router that routes learned on a network should not be re-broadcast to that network
|
|
How does poison reverse-processing work?
|
routes received from a network are re-broadcast to that network with a metric of 16
|
|
What does a route metric of 16 do?
|
tells the router that the route is unreachable
|
|
What is a broadcast router?
|
a router that can talk to any number of other routers
|
|
What is a point-to-point router?
|
a router that has only one peer
|
|
What are the three Network Type options for OSPF routers?
|
broadcast router, point-to-point router, and non-broadcast multiple access (NBMA)
|
|
What command-line tool is used to view the routing table?
|
route print
|
|
What is the protocol ID for Generic Routing Encapsulation (GRE)?
|
47
|
|
What TCP port does PPTP use?
|
TCP port 1723
|
|
What two Allow filters would be necessar to allow inbound PPTP traffic?
|
allow protocol ID 47 (GRE), and allow TCP port 1723 (PPTP)
|
|
What four filters are necessary to screen L2TP traffic?
|
input filter with destination IP address for VPN server, with subnet mask 255.255.255.255, protocol UDP, and destination port 500; corresponding outbound filter; input filter with destination IP address for VPN server, with subnet mask 255.255.255.255, protocol UDP, and destination port 1701; corresponding outbound filter
|
|
When creating demand-dial interfaces, what must be done to allow incoming calls to the router?
|
a suitable user account must be created for the remote router to use
|
|
What is the function of the OSPF Properties dialog box's External Routing tab?
|
to give control over which route sources the OSPF engine will use in addition to OSPF-delivered routes
|
|
Can RIP and OSPF coexist on a single RRAS server?
|
yes- they can even coexist on a single NIC
|
|
How do you control router discovery messages?
|
through the General tab of the Properties dialog box for a LAN interface
|
|
If OSPF routers are being used with a DSL or T1 connection, how should the RRAS server be configured?
|
as a point-to-point router
|
