Q:

You are considering upgrading a Windows NT Workstation 4.0 computer on your network to Windows 2000 Professional. The computer has 12 applications installed in addition to the operating system. All the applications are compatible with Windows 2000. The end user would benefit from the additional features Windows 2000 provides. What action should you take? 

A) Upgrade the Windows NT Workstation 4.0 computer to Windows 2000 Server B) Upgrade the Windows NT Workstation 4.0 computer to Windows 2000 Professional
C) Perform a clean install of Windows 2000 Professional on the Windows NT Workstation 4.0 computer D) Don't upgrade the Windows NT Workstation 4.0 computer, but install the Directory Service Client on it instead
 
Answer & Explanation Answer: B) Upgrade the Windows NT Workstation 4.0 computer to Windows 2000 Professional

Explanation:

Upgrading the computer to Windows 2000 Professional is probably the best choice given that the current operating system is Windows NT Workstation 4.0 (which upgrades easily to Windows 2000 Professional) and the fact that the computer has 12 additional applications installed on it that would need to be reinstalled and reconfigured if a clean install was performed.

Q:

What is the administrative distance of OSPF?

A) 90 B) 100
C) 110 D) 120
 
Answer & Explanation Answer: C) 110

Explanation:

The administrative distance (AD) is a very important parameter in a routing protocol. The lower the AD, the more trusted the route. If you have IGRP and OSPF running , by default IGRP routes would be placed in the routing table because IGRP has a lower AD of 100. OSPF has an AD of 110. RIPv1 and RIPv2 both have an AD of 120, and EIGRP is the lowest, at 90.

Q:

Two connected routers are configured only with RIP routing. What will be the result when a router receives a routing update that contains a higher-cost path to a network already in its routing table?

A) The updated information will be added to the existing routing table B) The update will be ignored and no further action will occur
C) The updated information will replace the existing routing table entry D) The existing routing table entry will be deleted from the routing table and all routers will exchange routing updates to reach convergence
 
Answer & Explanation Answer: B) The update will be ignored and no further action will occur

Explanation:

When a routing update is received by a router, the router first checks the administrative distance (AD) and always chooses the route with the lowest AD. However, if two routes are received and they both have the same AD and differing metrics , then the router will choose the one route with the lowest metrics or , in RIP's case, hop count.
