Explanation:
Here we are using route maps to change the route target for the 192.168.1.0/24 network from the
default route target of 64512:100010051 to 64512:3002300.
NO.2 Refer to the exhibit.
Which statement about the configuration is true?
A. This configuration is incorrect because the dialer interface number must be the same as the dialer
pool number.
B. This configuration is missing an IP address on the dialer interface.
C. This configuration is incorrect because the MTU must match the ppp-max-payload that is defined.
D. This configuration represents a complete PPPoE client configuration on an Ethernet connection.

NO.3 Which two statements about the function of a PIM designated router are true? (Choose two.)
A. It registers directly connected sources to the PIM rendezvous point.
B. It sends PIM Join/Prune messages for directly connected receivers.
C. It sends IGMP queries.
D. It forwards multicast traffic from the source into the PIM network.
E. It sends PIM asserts on the interfaces of the outgoing interface list.
Answer: A,B
400-101指導 400-101科目対策
Explanation:
In PIM ASM and SSM modes, the software chooses a designated router (DR) from the routers on each
network segment. The DR is responsible for forwarding multicast data for specified groups and
sources on that segment. In ASM mode, the DR is responsible for unicasting PIM register packets to
the RP. When a DR receives an IGMP membership report from a directly connected receiver, the
shortest path is formed to the RP, which may or may not go through the DR. The result is a shared
tree that connects all sources transmitting on the same multicast group to all receivers of that group.
In SSM mode, the DR triggers (*, G) or (S, G) PIM join messages toward the RP or the source. The path
from the receiver to the source is determined hop by hop. The source must be known to the receiver
or the DR.

NO.4 Refer to the exhibit.
Which statement is true?
A. IPv6 unicast routing is not enabled on this router.
B. Some IPv6 traffic will be blackholed from this router.
C. IPv6 traffic can be forwarded from this router, but only on Ethernet1/0.
D. There is no issue with forwarding IPv6 traffic from this router.
Answer: B
400-101勉強の資料
Explanation:
Here we see that the IPV6 default route shows two different paths to take, one via Ethernet 1/0 and
one via Ethernet 0/0.
However, only Eth 1/0 shows a next hop IPV6 address (the link local IPV6 address).
There is no link local next hop addressed known on Eth 0/0.
Therefore, traffic to all destinations will be load balanced over the two paths, but only half of the IPv6
traffic will be sent to the correct upstream router.
NO.5 For which two conditions is Cisco Express Forwarding recursion disabled by default when the
BGP Prefix Independent Convergence functionality is enabled? (Choose two.)
A. next hops learned with a /32 mask
B. next hops learned with a /24 mask
C. next hops that are directly connected
D. next hops learned with any mask shorter than /32
Answer: A,C
400-101価値 400-101某問題集
Explanation:
Recursion is the ability to find the next longest matching path when the primary path goes down.
When the BGP PIC feature is not installed, and if the next hop to a prefix fails, Cisco Express
Forwarding finds the next path to reach the prefix by recursing through the FIB to find the next
longest matching path to the prefix.
This is useful if the next hop is multiple hops away and there is more than one way of reaching the
next hop. However, with the BGP PIC feature, you may want to disable Cisco Express Forwarding
recursion for the following reasons:
- Recursion slows down convergence when Cisco Express Forwarding searches all the FIB entries.
- BGP PIC Edge already precomputes an alternate path, thus eliminating the need for Cisco Express
Forwarding recursion.
When the BGP PIC functionality is enabled, Cisco Express Forwarding recursion is disabled by default
for two conditions:
- For next hops learned with a /32 network mask (host routes) - For next hops that are directl
y connected For all other cases, Cisco Express Forwarding recursion is enabled.

NO.6 Which two Cisco IOS XE commands can install a subpackage onto a router? (Choose two.)
A. config-register value
B. issu loadversion rp identifier file diskType imageFilename
C. request platform software package install rp rpSlotNumber file fileURL
D. license install file storedLocationUrl
E. copy sourceUrl destinationUrl
F. boot system flash bootflash:filename
Answer: C,E
400-101認定
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:asr1000rp1adventerprisek9.02.01.00.122-33.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: Directory

NO.7 What is the cause of ignores and overruns on an interface, when the overall traffic rate of the
interface is low?
A. a bad cable
B. a hardware failure of the interface
C. a software bug
D. microbursts of traffic
Answer: D
Explanation:
Micro-bursting is a phenomenon where rapid bursts of data packets are sent in quick succession,
leading to periods of full line-rate transmission that can overflow packet buffers of the network stack,
both in network endpoints and routers and switches inside the network. Symptoms of micro bursts
will manifest in the form of ignores and/ or overruns (also shown as accumulated in "input error"
counter within show interface output). This is indicative of receive ring and corresponding packet
buffer being overwhelmed due to data bursts coming in over extremely short period of time
(microseconds). You will never see a sustained data traffic within show interface's "input rate"
counter as they are averaging bits per second (bps) over 5 minutes by default (way too long to
account for microbursts). You can understand microbursts from a scenario where a 3-lane highway
merging into a single lane at rush hour - the capacity burst cannot exceed the total available
bandwidth (i.e. single lane), but it can saturate it for a period of time.

A. The output shows an IPv6 multicast address that is used for unique local sources only.
B. The output shows an IPv6 multicast address with link-local scope.
C. The output shows an IPv6 multicast address that can be used for BIDIR-PIM only.
D. The output shows an IPv6 multicast address with embedded RP.
