by converting CE routes into VPNv4 routes and exchanging them using MP-BGP

by establishing BGP neighbor relationships between all connected CEs to exchange routing information

by learning IPv4 routes from connected CEs and redistributing them into the global IGP

by converting CE routes into VPNv4 routes and exchanging them using the global IGP

NEW QUESTION 42

RD

PW ID

NEW QUESTION 43
Drag and drop the EVPN components from the left onto the correct planes on the right.

NEW QUESTION 44
The network engineering group of a large ISP needs to harden the management plane of its Cisco 9000 Series ASRs. While addressing IPv6 ICMP issues, they realized they have to limit the rate at which IPv6 ICMP error messages are sent out on the network. Which command do they need to apply?

icmp ipv6 rate-limit unreachable 1000

ipv6 rate-limit 1000

icmp ipv4 rate-limit unreachable 1000

ipv6 icmp error-interval 50 20

NEW QUESTION 45
What is the primary function of a VRF on a router?

It enables the router to support multiple separate routing tables, which allows the device to handle overlapping IP addresses.

It enables a router to run BGP and a distance vector routing protocol at the same time, which allows it to serve as a VPN endpoint between remote sites.

It enables a router to configure VLANs locally, which provides segregation between networks.

It enables the router to provide faster switching through the network by using labels to identify the input and output interfaces for neighbor routers.

NEW QUESTION 46
Which two frames can be configured on an Ethernet flow point? (Choose two.)

of a specific VLAN

with different type of service values

with identical type of service value

with different class of service values

with no tags

NEW QUESTION 47
Which mechanism reduces the network flooding caused by host ARP learning behavior?

ARP suppression

storm control

root guard

BPDU guard

NEW QUESTION 48
Refer to the exhibit.

PE1 and PE2 are exchanging VPNv4 routes for CE1 and CE2, and PE3 contains the default route to the internet. If the three devices are operating normally, which two conclusions describe this configuration? (Choose two.)

The CE1 and CE2 VRFs can exchange routes only between their respective VRFs on PE1 and PE2.

All three routers must be running a distance-vector routing protocol.

All three routers must be running MP-BGP.

The CE1 and CE2 VRFs can access the default route provided by the Internet VRF.

Only the CE2 VRF can access the default route provided by the Internet VRF.

NEW QUESTION 49
Drag and drop the EVPN components from the left onto the correct planes on the right.

NEW QUESTION 50
In an Ethernet Virtual Circuit environment, which restriction do bridge domains have when STP is running?

The STP mode must be RSTP or PVST+

Bridge domains must be mapped to a different VLAN.

The STP mode must be MSTP

Bridge domains must belong to different MST instances.

NEW QUESTION 51
Refer to the exhibit.

A network engineer has been called to configure the four PE devices in order to enable full communication among the four CE devices connected to them. While starting to configure, he experienced a connectivity issue. Which two tasks should the engineer perform in order to begin the process correctly? (Choose two.)

Configure PE3 to export route-targets 100:1 and 200:2.

Configure PE3 to import route-targets 100:1 and 200:2.

Configure PE4 to import route-targets 101:1 and 202:2.

Configure PE2 to export route-targets 300:3 and 400:4.

Configure PE1 to import route-targets 300:3 and 400:4.

NEW QUESTION 52
Which statement describes the no bgp default route-target filter

Prefixes that are received with route targets and distinguisher are accepted.

Prefixes that are received with route targets and distinguisher are not accepted.

Prefixes that are received with route targets that are not imported at the PE are not accepted.

Prefixes that are received with route targets that are not imported at the PE are accepted.

NEW QUESTION 53
A network architect is troubleshooting the L2TPv3 tunneling security due to the untrusted nature of the underlaying network. Which two L2TPv3 features does the architect deploy to address the ongoing issues? (Choose two.)

TCP MD5 authentication

control message hashing

CHAP authentication

control message rate limiting

asymmetric mutual authentication with PSK

NEW QUESTION 54
Which two are characteristics of using a non-MPLS peer-to-peer model over a traditional overlay model?
(Choose two.)

The model is suited for nonredundant configurations.

The configuration on a newly added site PE is updated automatically.

Provider routers know the customer network topology.

The customer specifies the exact site-to-site traffic profile.

Routing information is exchanged between the customer router and one or a few PEs.

NEW QUESTION 55
You try to configure MPLS VPN VRF Selection based on a source IP address on an interface that has VRF configured, but you receive an error.
Which action must you take to correct the problem?

Change the source IP address.

Add the IP address to the VRF table.

Remove the VRF from the interface.

Configure static routes for the VRF.

NEW QUESTION 56
Refer to the exhibit.

Refer to the exhibit Router 1 is a P router in the ISP MPLS core A connected P router cannot generate an MPLS label for the router 1 loopback0 interface Which action resolves this issue?

The loopback0 interface must be in OSPF area 0.

The network statement under the routing process must have a wildcard mask of 0 0.0 255.

The OSPF network type must be changed on loopback0 to point-to-point

A static route to null 0 must be added for the loopback interface and then static routes must be redistributed into OSPF

NEW QUESTION 57
You are writing the requirements for an MPLS L3VPN environment that uses MP-BGP between PE routers.
In this environment, route targets and route distinguishers need to be advertised between the PE routers.
Which three operations meet these requirements? (Choose three.)
