> When checking a routing table, a network technician notices
the following entry: O*E2 0.0.0.0/0 [110/1] via 192.168.16.3, 00:20:22,
Serial0/0/0 What information can be gathered from this output?
This route is a propagated default route.*
The route is located two hops away.
No ipv6 ospf cost 10.
Verify that the interfaces that connect the two routers are in the same area.*
This route is a propagated default route.*
The route is located two hops away.
The edge of the OSPF area 0 is the interface that is
addressed 192.168.16.3.
The metric for this route is 110.
> Refer to the exhibit. A network administrator has configured
the OSPF timers to the values that are shown in the graphic. What is the result
of having those manually configured timers?.
The neighbor adjacency has formed.
The R1 dead timer expires between hello packets from R2.*
The hello timer on R2 expires every ten seconds.
R1 automatically adjusts its own timers to match the R2
timers.
> Refer to the exhibit. What kind of OSPF authentication has been configured on this interface?
> Refer to the exhibit. What kind of OSPF authentication has been configured on this interface?
Simple.
Plain text.
MD5.*
Null.
> Why do OSPF serial interfaces usually require manual
bandwidth configuration?
Each side of an OSPF serial link should be configured with a unique value.
All serial interfaces default to a value of 1.544 Mb/s.
Bandwidth value affects the actual speed of the link.
OSPF uses the bandwidth value to compute routes for its routing table.*
> Which command is used to verify that OSPF is enabled and
also provides a list of the networks that are being advertised by the network?.
Show ip protocols.*
Show ip route ospf.
Show ip ospf interface.
Show ip interface brief.
> A network engineer suspects that OSPFv3 routers are not
forming neighbor adjacencies because there are interface timer mismatches.
Which two commands can be issued on the interface of each OSFPv3 router to
resolve all timer mismatches?. (Choose two).
No ipv6 router ospf 10.
Ip ospf hello-interval 10.
No ipv6 ospf hello-interval.*
No ipv6 ospf dead-interval.*
Ip ospf dead-interval 40No ipv6 ospf cost 10.

When IPv4 and OSPFv2 are being used, the command #“show ip
ospf neighbor”# is used to verify that a router has formed an adjacency with
its neighboring routers.
> Refer to the exhibit. Four routers are connected to an
Ethernet LAN segment and are configured to run OSPFv3. However, none of the
routers are receiving routing updates. What is the cause of the problem?.
The routers are using IPv6 link local addresses to
communicate.
The network type has been set to BROADCAST instead of NBMA.
The
routers are using IPv4 addresses for router IDs.
All of the routers have an OSPFv3 interface priority of 0.*
> A network engineer is troubleshooting an OSPFv2 network and
discovers that two routers connected by a point-to-point WAN serial link are
not establishing an adjacency. The OSPF routing process, network commands and
area ID are all confirmed as correct, and the interfaces are not passive.
Testing shows that the cabling is correct, that the link is up, and pings
between the interfaces are successful. What is most likely the problem?.
The subnet masks on the two connected serial interfaces do not match.*
A clock rate has not been set on the DCE interface of the
serial link.
A DR election has not taken place.
The OSPFv2 process IDs on each router do not match.
> Which two pieces of information are used by the OSPF MD5
algorithm to generate a signature? (Choose two.)
Secret key.*
OSPF router ID.
OSPF message.*
Router hostname.
Interface IP address.
> When OSPFv2 neighbors are establishing adjacencies, in which
state do they elect a DR and BDR
router?
Loading state.
Init state.
Two-Way state.*
Exchange state.
> Refer to the exhibit. An administrator is trying to
configure R1 to run OSPFv3 but the neighbor adjacency is not forming with the
router connected to Fa0/0. What is the cause of the problem?.
FastEthernet0/0 has been configured as a passive interface.
No router ID has been configured.*
A link-local address has not been configured on interface
FastEthernet0/0.
The OSPF process ID and area values are backwards in the
interface configuration.
> Which command will a network engineer issue to verify the
configured hello and dead timer intervals on a point-to-point WAN link between
two routers that are running OSPFv2?.
Show ip ospf neighbor.
Show ipv6 ospf interface serial 0/0/0.
Show ip ospf interface fastethernet 0/1.
Show ip ospf interface serial 0/0/0.*
> Why is MD5 authentication more secure than simple
authentication for OSPF updates?.
MD5 uses both a username and a password to authenticate the neighbor.
MD5 requires passwords that are at least 8 characters long.
MD5 does not send the password to the neighbor router.*
MD5 employs IPsec to keep the updates from being intercepted.
> Refer to the exhibit. These two routers are configured to
run OSPFv3 but they are not forming a neighbor adjacency. What is the cause of
the problem?.
The routers are configured with the same router ID.*
The routers do not have global IPv6 addresses that are
configured on the Fa0/0 interfaces.
The routers have the same priority.
The routers have both been elected as the
DR.
> A network engineer is troubleshooting OSPFv2 routing issues
on two connected routers. Which two requirements to form an adjacency need to
be verified?. (Choose two).
Verify that the interfaces that connect the two routers are in the same subnet.*
Verify that one of the routers is the DR or BDR and the
other router a DRother.
Verify that both routers are using the same OSPFv2 process ID.Verify that the interfaces that connect the two routers are in the same area.*
> A network engineer is troubleshooting convergence and
adjacency issues in an OSPFv2 network and has noted that some expected network
route entries are not displayed in the routing table. Which two commands will
provide additional information about the state of router adjacencies, timer
intervals, and the area ID?. (Choose two).
Show ip route ospf.
Show ip ospf neighbor.*
Show ip protocols.
Show ip ospf interface.*
Show running-configuration.
> Refer to the exhibit. R1 and R2 are connected to the same
LAN segment and are configured to run
OSPFv3. They are not forming a neighbor adjacency. What is
the cause of the problem?.
The OSPFv3 process IDs of R1 and R2 are different.
The
priority value of both R1 and R2 is 1.
The timer intervals of R1 and R2 do not match.*
The IPv6 addresses of R1 and R2 are not in the same subnet.
> A network engineer has manually configured the hello
interval to 15 seconds on an interface of a router that is running OSPFv2. By
default, how will the dead interval on the interface be affected?.
The dead interval will now be 60 seconds.*
The dead interval will not change from the default value.
The dead interval will now be 15 seconds.
The dead interval will now be 30 seconds.
> Refer to the exhibit. Fill in the blank. Do not use
abbreviations.
The command #”show ipv6 route”# can be issued on router R2
to verify the propagation of a static default route from R1 to R2.
> Refer to the exhibit. What three conclusions can be drawn
from the displayed output? (Choose three).
The router ID on the DR router is 3.3.3.3
The router ID values were not the criteria used to select the DR and the BDR.*
There have been 9 seconds since the last hello packet sent.*
The DR can be reached through the GigabitEthernet 0/0 interface.*
This interface is using the default priority.
The BDR has three neighbors.
> Place the options in the following order:
*[+] Third*
*[+] Second.*
– not scored –.
*[+] First.*
*[+] Fourth.*
*[+] Order does not matter within this group.*
> A network administrator has just changed the router ID on a
router that is working in an OSPFv2 environment. What should the administrator
do to reset the adjacencies and use the new router ID?.
Issue the clear ip ospf process privileged mode command.*
Configure the network statements.
Change the OSPFv2 process
ID.
Change the interface priority.
