Questions # 18:

Refer to the exhibit:

Question # 18

R1 is connected to two service providers and is under a DDoS attack Which statement about this design is true if uRPF in strict mode is configured on both interfaces'?

Options:

R1 accepts source addresses on interface gigabitethernet0/1 that are private addresses

R1 permits asymmetric routing as long as the AS-RATH attribute entry matches the connected AS

R1 drops destination addresses that are routed to a null interface on the router

R1 drops all traffic that ingresses either interface that has a FIB entry that exits a different interface

Questions # 19:

A network engineer is configuring RIP as the routing protocol between multiple PEs and CEs. The engineer must avoid advertising the same routes back to their sources. Which action should be performed on the routers to accomplish this task?

Options:

Configure a different route distinguisher for each prefix.

Define the site of origin on each interface.

Define VRFs on each device to separate the traffic.

Enable bidirectional forwarding detection on each device.

Questions # 20:

An engineer must implement QoS to prioritize traffic that requires better service throughout the network. The engineer started by configuring a class map to identify the high-priority traffic. Which additional tasks must the engineer perform to implement the new QoS policy?

Options:

Attach the class map to a policy map that sets the minimum bandwidth allocated to the classified traffic and designates the action to be taken on the traffic.

Attach the class map to a policy map that designates the action to be taken on the classified traffic and then attach the policy map to an interface using a service policy.

Attach the class map to a policy map within a VRF to segregate the high-priority traffic and then attach the policy map to an interface in another VRF.

Create a route map to manipulate the routes that are entered into the routing table and then attach the route map to an interface using a service policy.

Questions # 21:

Question # 21

Refer to the exhibit. The application server in the data center hosts voice, video, and data applications over the internet. The data applications run more slowly than the voice and video applications. To ensure that all applications run smoothly, the service provider decided to implement a QoS policy on router PER 2 to apply traffic shaping. Which two actions must an engineer take to implement the task? (Choose two.)

Options:

Configure the scheduling function to handle delayed packets.

Enable packet remarking for priority traffic.

Configure a queue to buffer excess traffic.

Set the token value for secondary traffic.

Set a threshold to discard excess traffic.

Questions # 22:

Which action does the ingress VTEP perform on traffic between EVPN VXLAN overlays?

Options:

routing and tunneling when doing symmetric IRB

routing when doing asymmetric IRB

routing and bridging when doing asymmetric IRB

bridging when doing symmetric IRB

Questions # 23:

Question # 23

Options:

Questions # 24:

Drag and drop the functions from the left onto the Path Computation Element Protocol roles on the right.

Question # 24

Options:

Questions # 25:

A mod-size service provider uses L2VPN as its standard for connectivity between offices. A small company wants the service provider to connect the company’s two sites across the service provider core. To meet service requirements, the service provider must extend the layer 2 domain between the company’s two locations. Which configuration must the engineer apply to implement an attachment circuit between the two sites using a VLAN tag of 12?

Question # 25

Options:

Option A

Option B

Option C

Option D

Questions # 26:

Question # 26

Refer to the exhibit An engineer at ISP C is configuring a new interconnection with ISPs A and B using the BGP protocol After the initial configuration the engineer noticed high memory usage and an abnormally large LIB table on router R2 Which two actions must the engineer take on R2 to minimize memory usage? (Choose two.)

Options:

Configure Extended ACL 101 with accepted prefixes.

Confiure the mpls idp neighbor 11.11.11.11 labels accept1 command.

Configure Standard ACL 1 with accepted prefixes.

Configure the mpls idp neighbor 1.1.1.1 labels accept 101 command.

Configure the mpls idp neighbor 21.21.21.21 labels accept 101 command.

Question # 27

Options:

Questions # 28:

Question # 28

A network engineer is implementing an LDP-based MPLS solution to enable packet flow between the two bank sites The engineer was given two requirements

·LDP peering must stay up when there is a link failure between R3 and R6

·LDP peering must not flap when there is a link failure between R5 and R6

Which action meets these requirements?

Options:

Enable Link LDP on R4 and R6

Reset the LDP session between R4 and R6

Configure LDP Session Protection on R4

Implement an LDP targeted session with R4 on R6

Questions # 29:

A new PE router is configured to run OSPF as an IGP with LDP on all interfaces. The engineer is trying to prevent black holes after convergence when the PERSON device loses an LDP session with other PE routers. Which action must the engineer take to implement LDP session protection on a new PE router?

Options:

Configure the mpls ldp session protection and mpls label protocol ldp commands on the interfaces on the new PE router that connect to the CENTER routers.

Configure the mpls ldp discovery targeted-hello accept and mpls ldp session protection commands on the interfaces on the new PE router that connect to the CE routers.

Configure the new PE router with the mpls ldp session protection command and on neighboring routers that connect to this new PE router.

Questions # 30:

Question # 30

Refer to the exhibit. Company A's network architect is implementing the capabilities that are described in RFC 4379 to provide new options for troubleshooting the company's MPLS network. MPLS LSPs are signaled via the BGP routing protocol with IPv4 unicast prefix FECs. Due to company security policies, access is controlled on the control plane and management plane. Which two tasks must the architect perform to achieve the goal? (Choose two.)
