Question 1

Refer to the exhibit. Which attribute can router 1 alter so that only other iBGP peers prefer to use 192.168.4.2 as the next hop for route 192.168.3.0/24?

MED

local preference

origin

weight

Question 2

Which command is used to enable BIDIR-PIM under global configuration mode for Cisco IOS XE Sofware?

ip pim bidir-enable

ipv4 pim bidir-enable

ip multicast-routing

ip pim bidir

Question 3

Which output from the show isis interface command helps an engineer troubleshoot an IS-IS adjacency problem on a Cisco IOS-XR platform?

metric

priority

circuit type

hello interval

Question 4

Refer to the exhibit. A network operator must stop 10.33.33.33/32 from being redistributed into Level 1 router XR1. Which configuration meets this need?

$\"300-510$

Question 5

Refer to the exhibit. CE1 and CE2 cannot communicate through the service provider BGP peering is established between PE1 and PE2. IS-IS is the only routing protocol running in the service provider core. What step can be done to troubleshoot the issue?

Switch the IGPs running in the core from IS-IS to OSPF to support a Cisco MPLS TE tunnel from PE1 to PE2.

Configure BGP between CE and PE routers.

Confirm that IS-IS is running with metric-style narrow.

Verify the MPLS LSPs.

Question 6

Refer to the exhibit. Why is neighbor 10.1.5.5 stuck in “2WAY” state?

Router ID 10.1.5.5 is not reachable from R2

OSPF authentication has failed between R2 and 10.1.5.5

It is an expected behavior when OSPF network type is broadcast

OSPF parameters (Area ID or hello interval) are mismatched between R2 and 10.1.5.5

Question 7

Which cost is the default when redistributing routes from BGP to OSPF?

infinite

automatic

Question 8

Which two statements about mapping multicast IP addresses to MAC addresses are true? (Choose two.)

All mapped multicast MAC addresses begin with 0x0100.5E

The router performs the mapping before it hands the packet off to a switch

All multicast MAC addresses end with 0x0100.5E

The mapping process may generate overlapping addresses, which can cause receivers to receive unwanted packets

All destination MAC addresses begin with an octet of binary 1s

Question 9

Refer to the exhibit. Which router does R1 install as an alternate next hop when trying to reach R3 if LFA is enabled?

Question 10

Which statement about BFD on Cisco IOS XR Software is true?

Cisco IOS XR router must use LDP to route back to the Cisco IOS router to establish the peer relationship.

Cisco IOS XR Software does not support BFD multihop for IPv4.

Cisco IOS XR router must use dynamic routing or a static route back to the Cisco IOS router to establish the peer relationship.

BFD is not compatible between Cisco IOS XR and Cisco IOS Software.

Question 11

Refer to the exhibit. An engineer is addressing an IS-IS design issue which is running within the topology. All links are running on FastEthernet, except the link between R5 and R4, which is Gigabit Ethernet. Which statement about the design is true?

R4 prefer to reach R5 using R1 as the next hop

All links have equal cost if the default metric is used

R5 prefers to use R4 as the next hop for all routes

R1 prefer to use R5 as the next hop to reach R4

Question 12

A network engineer is troubleshooting OSPF multiarea. Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?

hierarchical CLI

DR support for topology management

routing process enabled by default on all interfaces

show ip ospf topology command

Question 13

Refer to the exhibit. Router 1 is connected to router 2 on interface TenGigE0/1. Which interface provides the alternate path to 172.16.200.9/32 when the link between router 1 and router 2 goes down?

TenGigE0/1 interface provides the alternate path

A backup path must be statically installed

TenGigE0/2 interface provides the alternate path

A primary path must be manually installed

Question 14

What is used by SR-TE to steer traffic through the network?

shortest path calculated by IGP

dynamic rules

path policy

explicit maps

Question 15

Refer to the exhibit. How are packets directed through the data plane when SRv6 is implemented?
300-510 dumps exhibit

An ordered list of segments is encoded in a routing extension header

The MPLS data plane is used to push labels onto IGP routes

A stack of labels represents an ordered list of segments

The packet is encapsulated with a header and trailer encoding the ordered list of segments

Question 16

In a PIM-SM environment, which mechanism determines the traffic that a receiver receives?

The receiver explicitly requests its desired traffic from the RP on the shared tree.

The receiver explicitly requests traffic from a single source, which responds by forwarding all traffic.

The RP on the shared tree floods traffic out of all PIM configured interfaces.

The receiver explicitly requests traffic from each desired source, which responds by sending all traffic.

Question 17

Refer to the exhibit. XR1 and XR2 are sending the prefix 10.11.11.0/24 to XR3. A configured policy on XR1 is incorrectly prepending AS path 11 11 12 12 onto this prefix. A network operator wants to add a policy onto XR3 that will not allow the falsely prepending prefix from being installed. Which policy configuration applied to the XR3 neighbor configuration for XR1 can accomplish this requirement without impact to other or future received routes?

$\"300-510$

$\"300-510$ C. $\"300-510$

$\"300-510$

Question 18

Refer to the exhibit. Which task must you perform on interface g1/0/0 to complete the SSM implementation?

configure OSPFv3

enable CDP

disable IGMP

configure IGMPv3

Question 19

A network consultant is troubleshooting IS-IS instances to identify why a routing domains is having communication problems between the two instances. Which description of the possible cause of issues in the routing domain is true?

The same interface cannot be advertised in two different IS-IS instances

The IS-IS “ISP” and “ISP2” instances are unrelated and unable to intercommunicate

The configured IS-IS NSEL value is not allowing the routing systems to establish a neighborship

The interface mode ip router is-is command was not included in the script

Question 20

Which task is performed when troubleshooting LDP?

Execute the ping utility to generate information about the MAC addresses used along the path

Verify that MPLS is disabled globally and enabled on the necessary interfaces in a per-interface basis

Execute the traceroute utility to generate information about the labels used along the path

Verify that Cisco Express Forwarding has been disabled on the network

Question 21

Refer to the exhibit. After troubleshooting BGP traffic steering issue, which action did the network operator take to achieve the correct effect of this configuration?

Routes that have passed through AS 65517 have the local preference set to 150.

Routes that have originated through AS 65517 have the local preference set to 150.

Routes directly attached to AS 65517 have the local preference set to 150.

Routes that have passed through AS 65517 have the local preference set to 150 and the traffic is denied.
