6. A network engineer is troubleshooting a newly deployed wireless network that is using the latest 802.11 standards. When users access high bandwidth services such as streaming video, the wireless network performance is poor. To improve performance the network engineer decides to configure a 5 Ghz frequency band SSID and train users to use that SSID for streaming media services. Why might this solution improve the wireless network performance for that type of service?
The only users that can switch to the 5 GHz band will be those with the latest wireless NICs, which will reduce usage.
The 5 GHz band has a greater range and is therefore likely to be interference-free.
Requiring the users to switch to the 5 GHz band for streaming media is inconvenient and will result in fewer users accessing these services.
The 5 GHz band has more channels and is less crowded than the 2.4 GHz band, which makes it more suited to streaming multimedia.

7. Which function is provided by EtherChannel?
spreading traffic across multiple physical WAN links
creating one logical link by using multiple physical links between two LAN switches
dividing the bandwidth of a single link into separate time slots
enabling traffic from multiple VLANs to travel over a single Layer 2 link

_______________________________________________________________

9
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 protocols
show ip route ospf
show running-configuration
show ip ospf interface

_______________________________________________________________

10

Refer to the exhibit. What kind of OSPF authentication has been configured on this interface?

plain text
null
simple
MD5
_______________________________________________________________

_______________________________________________________________

12
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 interface brief
show ip route ospf
show ip protocols 
show ip ospf interface
_______________________________________________________________

13

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 IPv6 addresses of R1 and R2 are not in the same subnet.
The OSPFv3 process IDs of R1 and R2 are different.
The timer intervals of R1 and R2 do not match. 
The priority value of both R1 and R2 is 1.
_______________________________________________________________

14

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?

All of the routers have an OSPFv3 interface priority of 0. 
The network type has been set to BROADCAST instead of NBMA.
The routers are using IPv6 link local addresses to communicate.
The routers are using IPv4 addresses for router IDs.
_______________________________________________________________

15

Refer to the exhibit. What three conclusions can be drawn from the displayed output? (Choose three.)

This interface is using the default priority.
The router ID values were not the criteria used to select the DR and the BDR.
The DR can be reached through the GigabitEthernet 0/0 interface. 
The router ID on the DR router is 3.3.3.3
The BDR has three neighbors.
There have been 9 seconds since the last hello packet sent.
_______________________________________________________________

16
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 one of the routers is the DR or BDR and the other router a DRother.
Verify that one of the interfaces that connects the two routers is active and the other passive.
Verify that the interfaces that connect the two routers are in the same area. 
Verify that both routers are using the same OSPFv2 process ID.
Verify that the interfaces that connect the two routers are in the same subnet.
_______________________________________________________________

_______________________________________________________________

18
Why do OSPF serial interfaces usually require manual bandwidth configuration?
OSPF uses the bandwidth value to compute routes for its routing table. 
All serial interfaces default to a value of 1.544 Mb/s.
Bandwidth value affects the actual speed of the link.
Each side of an OSPF serial link should be configured with a unique value

_______________________________________________________________

19

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 have both been elected as the DR.
The routers do not have global IPv6 addresses that are configured on the Fa0/0 interfaces.
The routers are configured with the same router ID. 
The routers have the same priority.
_______________________________________________________________

20

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?

A link-local address has not been configured on interface FastEthernet0/0.
No router ID has been configured. 
FastEthernet0/0 has been configured as a passive interface.
The OSPF process ID and area values are backwards in the interface configuration.
_______________________________________________________________

21
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.)

ip ospf hello-interval 10
no ipv6 ospf hello-interval
no ipv6 router ospf 10
no ipv6 ospf dead-interval
ip ospf dead-interval 40
no ipv6 ospf cost 10
_______________________________________________________________

22

Fill in the blank. Do not use abbreviations.
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.
_______________________________________________________________

23
Why is MD5 authentication more secure than simple authentication for OSPF updates?

MD5 employs IPsec to keep the updates from being intercepted.
MD5 does not send the password to the neighbor router. 
MD5 uses both a username and a password to authenticate the neighbor.
MD5 requires passwords that are at least 8 characters long.
_______________________________________________________________

24
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 OSPFv2 process IDs on each router do not match.
A clock rate has not been set on the DCE interface of the serial link.
The subnet masks on the two connected serial interfaces do not match. 
A DR election has not taken place.
