- 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
