1.The Dev1
and Dev3
routers are OSPF neighbors over the Ethernet 0/0 connection. Based on
the show ip ospf neighbor output from the Dev1
and Dev3
routers, which statement is true?
A.Dev1
is the DR because it has a higher OSPF router priority.
B.Dev1
is the DR because it has a lower OSPF router ID.
C.Dev3
is the DR because it has a higher OSPF router priority.
D.Dev3
is the DR because it has a lower OSPF router ID.
E.Both Dev1
and Dev3
are using the default OSPF router priority.
Correct:A
2.Refer to the exhibit. Router RA is not able to ping the loopback Lo0 on router RB. What could the
problem be?
A.The loopback addresses have different subnet masks.
B.Router RA is using RIP version 1 while Router RB is using RIP version 2.
C.Router RA is using plain text authentication while Router RB is using encrypted authentication.
D.MD5 authentication is not possible with RIP.
E.The key strings do not match.
F.The key chains do not match.
Correct:C
3.When the BGP path selection process is being performed on a Cisco router, which BGP attribute
is used first when determining the best path?
A.local preference
B.MED
C.weight
D.origin
E.nexthop
F.ASpath
Correct:C
4.Which two are characteristics of the ISIS
protocol but not OSPF? (Choose two.)
A.provides for network scalability by allowing the network to be separated into areas
B.provides routing support for multiple network layer protocols
C.three layers of hierarchical routing
D.utilizes SPF algorithm
E.forms adjacencies with all neighbors
F.supports demand circuit routing
Correct:B E
5.Which three characteristics apply to ISIS
but not to OSPF? (Choose three.)
A.encapsulates PDUs directly into a datalink
frame
B.uses a DIS and a backup DIS to present the psuedonode
on the LAN
C.uses stubby areas to improve network scalability
D.uses a default IOS metric of 10 on each interface
E.runs PRC (Partial Route Calculations) to calculate IP reachability information
F.uses an ondemand
circuit to reduce the hello and LSA flooding across switched WAN links, such as
ISDN
Correct:A D E
6.What are two routing protocols defined by the OSI protocol suite at the network layer? (Choose
two.)
A.End SystemtoEnd
System
B.Routing Information Protocol
C.Interior Gateway Routing Protocol
D.End SystemtoIntermediate
System
E.Intermediate SystemtoIntermediate
System
Correct:D E
7.Refer to exhibit. BGP is configured on all routers, synchronization is turned off, and none of the
default attributes have been changed except the local preference attribute on R4. Which path will
be preferred by R2 to reach the network 100.100.100.0/24?
A.R2 R3
R4
R5
because it has a lower admin distance
B.R2 R3
R4
R5
because it has a higher local preference
C.R2 R1
because it has the shortest ASpath
D.R2 R1
because it has a lower local preference
Correct:B
8.Router E is configured with the EIGRP variance 2 command. What path will Router E take to
reach Router A?
A.only EDA
B.only EBA
C.only ECA
D.both EBA
and ECA
E.both EBA
and EDA
F.all available paths.
Correct:D
