Q291. Refer to the exhibit.
Which statement is true?
A. 2001:DB8::1/128 is a local host route, and it can be redistributed into a dynamic routing protocol.
B. 2001:DB8::1/128 is a local host route, and it cannot be redistributed into a dynamic routing protocol.
C. 2001:DB8::1/128 is a local host route that was created because ipv6 unicast-routing is not enabled on this router.
D. 2001:DB8::1/128 is a route that was put in the IPv6 routing table because one of this router's loopback interfaces has the IPv6 address 2001:DB8::1/128.
Answer: B
Explanation:
The local routes have the administrative distance of 0. This is the same adminstrative distance as connected routes. However, when you configure redistributed connected under any routing process, the connected routes are redistributed, but the local routes are not. This behavior allows the networks to not require a large number of host routes, because the networks of the interfaces are advertised with their proper masks. These host routes are only needed on the router that owns the IP address in order to process packets destined to that IP address.
It is normal for local host routes to be listed in the IPv4 and IPv6 routing table for IP addresses of the router's interfaces. Their purpose is to create a corresponding CEF entry as a receive entry so that the packets destined to this IP address can be processed by the router itself. These routes cannot be redistributed into any routing protocol.

Q292. Which statement describes what it means if a router has an OSPF priority set to 0?
A. A router with the OSPF priority set to 0 is one that can participate in the election of a DR. It has the highest priority.
B. A router with the OSPF priority set to 0 is one that cannot participate in the election of a DR, but it can become a BDR
C. A router with the OSPF priority set to 0 is one that cannot participate in the election of a DR. It can become neither a DR nor a BDR.
D. A router with the OSPF priority set to 0 is one that cannot participate in the election of a BDR, but it can become a DR
Answer: C
Q293. What is the function of an implicit-null label?
A. It notifies the upstream LSR to remove the top label in the label stack and forward the packet.
B. It notifies the upstream LSR to add a VPN label to the label stack.
C. It is used to statically assign a label to an IGP route.
D. It is used to identify the router ID.
Answer: A
Q294. What are the minimal configuration steps that are required to configure EIGRP HMAC-SHA2 authentication?
A. classic router mode, interface XX, authentication mode hmac-sha-256 <password>
B. named router mode, address-family statement, authentication mode hmac-sha-256 <password>
C. named router mode, address-family statement, af-interface default, authentication mode hmac-sha-256 <password>
D. named router mode, address-family statement, authentication mode hmac-sha-256 <password>
Answer: C
Explanation:
The example below shows how to configure EIGRP HMAC-SHA2 on Cisco router:
Device(config)# router eigrp name1
Device(config-router)# address-family ipv4 autonomous-system 45000
Device(config-router-af)# af-interface ethernet 0/0
Device(config-router-af-interface)# authentication mode hmac-sha-256 0 password1
Device(config-router-af-interface)# end

Q295. Which two Cisco IOS XE commands can install a subpackage onto a router? (Choose two.)
A. request platform software package install rp rpSlotNumber file fileURL
B. boot system flash bootflash:filename
C. copy sourceUrl destinationUrl
D. license install file storedLocationUrl
E. issu loadversion rp identifier file diskType imageFilename
F. config-register value
Answer: A,C
Explanation:
. Managing and Configuring a Consolidated Package Using the request platform software package install Command
In the following example, the request platform software package install command is used to upgrade a consolidated package running on RP 0. The force option, which forces the upgrade past any prompt (such as already having the same consolidated package installed), is used in this example.
Router# request platform software package install rp 0 file bootflash:asr1000rp1-adventerprisek9.02.01.00.122-33.XNA.bin force
To upgrade a consolidated package on the Cisco ASR 1000 Series Routers using the copy command, copy the consolidated package into the bootflash: directory on the router using the copy command as you would on most other Cisco routers. After making this copy, configure the router to boot using the consolidated package file. In the following example, the consolidated package file is copied onto the bootflash: file system from TFTP. The config-register is then set to boot using boot system commands, and the boot system commands instruct the router to boot using the consolidated package stored in the bootflash: file system. The new configuration is then saved using the copy running-config startup-config command, and the system is then reloaded to complete the process.
Router# dir bootflash:

Q296. Where must the spanning-tree timers be configured if they are not using the default timers?
A. They must be on the root bridge.
B. They must be on any non-root bridge.
C. Changing the default timers is not allowed.
D. Timers must be modified manually on each switch.
Answer: A
Q297. Which two statements best describes the difference between active mode monitoring and passive mode monitoring? (Choose two.)
A. Active mode monitoring is the act of Cisco PfR gathering information on user packets assembled into flows by NetFlow.
B. Active mode monitoring uses IP SLA probes for obtaining performance characteristics of the current exit WAN link.
C. Passive mode monitoring uses IP SLA to generate probes for the purpose of obtaining information regarding the characteristics of the WAN links.
D. Passive mode monitoring uses NetFlow for obtaining performance characteristics of the exit WAN links.
Answer: B,D
Q298. Refer to the exhibit.
Which two options are effects of the given configuration? (Choose two.)
A. It sets the data export destination to 209.165.200.227 on UDP port 49152.
B. It enables Cisco Express Forwarding on interface FastEthernet0/0.
C. It configures the export process to include the BGP peer AS of the router gathering the data.
D. It enables NetFlow switching on interface FastEthernet0/0.
E. It sets the data export destination to 209.165.200.227 on TCP port 49152.
Answer: A,D
Explanation:
The “ip flow-export destination 209.165.200.227 49152” command specifies that the data export destination server is 209.165.200.227 using UDP port 49152.
The “ip route-cache flow” command under the fastethernet 0/0 interface enable netflow switching on that interface.
Q299. Which two discovery mechanism does LDP support? (Choose two.)
A. strict
B. extended
C. loose
D. targeted
E. basic
Answer: B,E
