45,the mesh group feature is a mechanism to reduce flooding of LSPs in nonbroadcast multi-access (NBMA) networks with highly meshed, point to point topologies
46,when configuring ISIS,why it is important to manually configure the link costs for each of the associated links within the network?
a.because by default, all links have a cost of 10 regardless of the bandwidth
47,if a router already has a route to the 172.27.0.0/16 network in the routing table,which of the following commands would cause EIGRP to flag that network as the candidate default route?
a.ip default-network 172.27.0.0
48,which IOS command below would be useful if you had to create a static list of the other routers in your NBMA cloud?

49,RIP,IGRP,EIGRP assign a default metric 0 to redistributed routes and will only advertise these routes if a valid seed metric is configured
ISIS assigns a default metric of 0 to redistributed routes
OSPF assigns a default metric of 20 for routes from all protocols except BGP, which gets a metric of 1

b.route redistribution
d.address aggregation
54,TestKing is using Metro Ethernet as their Core backbone network.What does VLAN tunneling in the Metro Ethernet environment do for a customer?
a.extends their logical network topology across wide geographic networks
b.renumbers their LANs
c.provides combined wavelength routing
d.translates their VLANs at the service provider edge
answer:d
55,ISIS has become the leading interior routing protocol(IGP) in use by internet service providers
56,ODR is being used as the routing protocol for a new TestKing network.which network totology is best suited for ODR?
a.highly redundant
b.fully meshed
c.dual self-healing ring
d.hub and spoke
e.NBMA
answer:d
57,which three network issues indicate a need to implement QoS features?
a.mis-routed packets
b.excess jitter
c.delay of critical traffic
d.packet loss due to congestion
e.data link layer broadcast storms
f.ftp connections unsuccessful
answer:b,c,d
58,which three QoS mechanisms can be configured to improve VoIP quality on a converged network?
a.the use of a queuing method that will give VoIP traffic strict priority over other traffic
b.the use of RTP header compression for the VoIP traffic
c.the proper classfication and marking of the traffic as close to the source as possible
d.the use of 802.1QinQ trunking for VoIP traffic
e.the use of WRED for the VoIP traffic
answer:a,c,e
59,what protocol specified by RFC 1256 will allow an enabled IP host to find a new router when a router becomes unavailable?
a.IRDP
b.SNMP
c.HSRP
d.VRRP
answer:a
some newer IP hosts use ICMP Router Discovery Protocol(IRDP) to find a new router when a router becomes unavailable
60,which of the following statements about route summarization are true?
a.private addresses cannot be summarized
b.summarization is not compatible with VLSM
c.RIP v.1 automatically summarizes routes on network class boundaries
d.classless routing protocols support summarization on any address bit boundary
answer:c,d
61,your network is using the Class B private IP address scheme,as defined in RFC 1918. if you wanted to summarize this entire private address space into one single supernet, which prefix should you use?
b./12
62,you are troubleshooting an OSPF problem and you need to view the OSPF neighbor information.which of the following commands should you enter to examine neighbor adjacencies?
a.show ip ospf database
b.show ip ospf neighbors
c.show ip ospf protocols
d.show ip ospf interfaces
answer:b,d
63,you have a multi-area OSPF network and you're concerned because one of the sites is having connectivity problem to resources in a different area .which IOS privileged mode command would you enter to confirm that your network:a) has a path to its ABR,b) has a path to its ASBR,and c) the SPF calculation is functional?
d.show ip ospf border-routers
64,which IOS command tells you how many times the OSPF shortest path first algorithm was executed?
c.show ip ospf
65,to establish a full mesh IBGP between ten routers, how many IBGP sessions are required?
a.10
b.45
c.50
d.90
e.100
answer:b
for full mesh x*(x-1)/2 connections are needed.
