Cisco® 400-201 Exam Practice Questions (P. 5)

Refer to the exhibit. Which statement is true about what this AS filter accomplishes?

Refer to the exhibit. A network engineer from ISP 2 is designing the BGP architecture with a requirement of preventing their customer AS 65001 from becoming a
Transit AS, using the following configuration:
router bgp 65000
neighbor 10.0.0.1 remote-as 65001
neighbor 10.0.0.1 route-map BGP-ROUTE-POLICY in
Which two Cisco IOS command should be used within the route-map to achieve this goal on ISP 2 from AS 65000?

Which protocol provides an alternative to the STP, which provides a way to control network loops, handle link failures, and improve convergence time and can coexist with STP?

Which three configuration sections are required on service provider PE routers to enable IPv4 Layer 3 VPN? (Choose three.)

A VPLS network consists of provider edge routers that have fully meshed pseudowires. The network runs unicast and multicast traffic. The network recently experienced bandwidth- and CPU-related performance issues. While monitoring the VPLS statistics and interface statistics, you note that the network is experiencing an unusual amount of broadcasts and undesired multicast on the network. Which two techniques should the operations team consider in addressing these problems?

In an inter-AS L3VPN Option B, the PE-ASBRs use which routing table to store all the VPN routes that needs to be exchanged?

Refer to the exhibit. IPTV video clients are connected to R6. Unicast and multicast traffic flows from R1 to R6. The OSPF cost of the R1-R2-R3-R6 path is lower than the R1-R5-R4-R3-R6 path.
To enable load sharing and fast reroute, the design team decided to implement MPLS TE tunnels between R1 and R3. After the MPLS TE tunnels are deployed, the multicast traffic stops working.
While troubleshooting the issue, the operations engineer noticed that the OSPF route to the multicast source is learned via the MPLS TE tunnel, which causes the
RPF check to fail. Which two solutions can prevent the multicast traffic from being affected by the RPF check failure due to the MPLS TE tunnel deployment?
(Choose two.)

A service provider NOC engineer received numerous support tickets from their VPN customers. These customers are reporting packet loss between two PE routers. The NOC engineer created a VRF TEMP to run tests between these two PE routers, and no errors were reported. ECMP links are used between P and
PE routers.
Which test can quickly identify the core link that is causing the problems?

DRAG DROP -
Drag and drop the MPLS Inter-AS VPN options on the left onto the correct description on the right.
Select and Place:

Refer to the exhibit. A company has four office locations, which are identified as 1, 2, 3 and 4. The PE routers at these locations have assigned RDs of 10:10,
20:20, 30:30, and 40:40, respectively. Locations 1 and 3 need to share routing information, which configuration will allow this?
