Refer to the exhibit. What are two results of issuing the displayed commands on S1, S2, and S3? (Choose two.)
S3 can be elected as a secondary bridge.
S2 can become root bridge if S3 fails.
S1 will automatically adjust the priority to be the lowest.
S2 can become root bridge if S1 fails.
S1 will automatically adjust the priority to be the highest.
S1 will automatically adjust the priority to be the lowest.
S2 can become root bridge if S1 fails.
A network engineer is troubleshooting a single-area OSPFv3 implementation across routers R1, R2, and R3. During the verification of the implementation, it is noted that the routing tables on R1 and R2 do not include the entry for a remote LAN on R3. Examination of R3 shows the following:
that all interfaces have correct addressing
that the routing process has been globally configured
that correct router adjacencies have formed
What additional action taken on R3 could solve the problem?
Force DR/BDR elections to occur where required.
Use the network command to configure the LAN network under the global routing process.
Enable the OSPFv3 routing process on the interface connected to the remote LAN.
Restart the OPSFv3 routing process.
Enable the OSPFv3 routing process on the interface connected to the remote LAN.
Fill in the blank. Use the acronym.
Which encryption protocol is used by the WPA2 shared key authentication technique?
AES
What are two features of OSPF interarea route summarization? (Choose two.)
ASBRs perform all OSPF summarization.
Routes within an area are summarized by the ABR.
Route summarization results in high network traffic and router overhead.
ABRs advertise the summarized routes into the backbone.
Type 3 and type 5 LSAs are used to propagate summarized routes.
Routes within an area are summarized by the ABR.
ABRs advertise the summarized routes into the backbone.
Refer to the exhibit. A company has migrated from single area OSPF to multiarea. However, none of the users from network 192.168.1.0/24 in the new area can be reached by anyone in the Branch1 office. From the output in the exhibit, what is the problem?
There are no interarea routes in the routing table for network 192.168.1.0.
The OSPF routing process is inactive.
The router has not established any adjacencies with other OSPF routers.
The link to the new area is down.
There are no interarea routes in the routing table for network 192.168.1.0.
What are two requirements when using out-of-band configuration of a Cisco IOS network device? (Choose two.)
Telnet or SSH access to the device
a connection to an operational network interface on the device
a direct connection to the console or AUX port
a terminal emulation client
HTTP access to the device
a direct connection to the console or AUX port
a terminal emulation client
For troubleshooting missing EIGRP routes on a router, what three types of information can be collected using the show ip protocols command? (Choose three.)
any interfaces on the router that are configured as passive
any ACLs that are affecting the EIGRP routing process
any interfaces that are enabled for EIGRP authentication
networks that are unadvertised by the EIGRP routing protocol
the local interface that is used to establish an adjacency with EIGRP neighbors
the IP addresses that are configured on adjacent routers
any interfaces on the router that are configured as passive
any ACLs that are affecting the EIGRP routing process
networks that are unadvertised by the EIGRP routing protocol
What are two requirements to be able to configure an EtherChannel between two switches? (Choose two.)
All the interfaces need to work at the same speed.
All interfaces need to be assigned to different VLANs.
The interfaces that are involved need to be contiguous on the switch.
All the interfaces need to be working in the same duplex mode.
Different allowed ranges of VLANs must exist on each end.
All the interfaces need to work at the same speed.
All the interfaces need to be working in the same duplex mode.
Refer to the exhibit. Why did R1 and R2 not establish ad adjacency?
The link-local address must be the same on both routers.
The AS number must be the same on R1 and R2.
R1 S0/0/0 and R2 S0/0/0 are on different networks.
The no shutdown command is misapplied on both routers.
The router ID must be the same on both routers.
The AS number must be the same on R1 and R2.
Refer to the exhibit. Router CiscoVille has been partially configured for EIGRP authentication. What is missing that would allow successful authentication between EIGRP neighbors?
The interfaces that will use EIGRP authentication must be specified.
The CiscoVIlle router requires a second keychain to function correctly when using two interfaces for EIGRP authentication.
The same key number must be used on any EIGRP neighbor routers.
The keychain for EIGRP authentication must be configured on the interfaces.
The keychain for EIGRP authentication must be configured on the interfaces.
An EIGRP router loses the route to a network. Its topology table contains two feasible successors to the same network. What action will the router take?
The router will query neighbors for an alternate route.
The router uses the default route.
The DUAL algorithm is recomputed to find an alternate route.
The best alternative backup route is immediately inserted into the routing table.
The best alternative backup route is immediately inserted into the routing table.
