Refer to the exhibit Routers R1 and R2 are connected via a señal link and use the IS-IS routing protocol for route exchange After a configuration change on R2. IS-IS connectivity is interrupted A network engineer confirmed that the interfaces are in the UP state and connectivity exists between the two routers. Which two actions must the engineer perform to resolve the problem? (Choose two.)
Which programmable API allows the service provider to plan and optimize the automation of network operations and achieve closed-loop operations?
An engineer implemented LDP protocol on the ISP network. The engineer must ensure that there are no packet loss issues when IGP and LDP protocols are not synchronized. Which configuring must the engineer implement so that the IGP routing protocol will wait until LDP convergence is completed?
Refer to the exhibit:

What does this value mean when it is received in XML?
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?
Drag and drop the characteristics from the left onto the corresponding radio splitting approaches on the right

A service provider is in the process of implementing Unified MPLS on an enterprise network with many nodes. After the migration, several new customers will be added to the environment. RFC 3107 is used to build BGP LSPs across the domains. Which action must the networking team take to reduce the full-mesh requirement for IBGP?
Refer to the exhibit.

A network engineer at a large ISP Is configuring telemetry streams to monitor the health status of PE routers on the network using gRPC dial-out. The PE routers are located at several data centers in different physical locations, and they are using IS-IS and BGP for routing. Which additional configuration must the engineer implement on the PE routers to meet the goal?

Refer to the exhibit. What is the purpose of this JSON script?
Drag and drop the NAT64 descriptions from the left onto the correct NAT64 types on the right.

What is the primary role of a BR router in a 6rd environment?
ASN 65001 is peering with ASN 65002 to exchange IPv6 BGP routes. All routes that originate in ASN 65001 have a standard community value of 65001:100, and ASN 65002 is allowed to advertise only 2001 :db8:aaaa::/48. An engineer needs to update the ASN 65001 route-filtering configuration to meet these conditions:
* Looped routes into ASN 65001 and routes that have traversed 10 or more ASNs must be denied.
* Routes accepted into ASN 65001 must be assigned a community value of 65001:200.
Which configuration must the engineer apply to the ASN 65001 border router?



Refer to the exhibit.

The customer that owns the CE-1, CE-2, and CE-3 routers purchased point-to-point E-Line services from the Carrier Ethernet provider. The service provider is delivering multiplexed UNI at the customer HQ location on PE-1 and untagged UNIs at the PE-2 and PE-3 locations. Additionally, the customer provided these VLAN to EVC mapping requirements:
• EVC 1 between CE-1 and CE-2 must be provisioned with C-VLAN 12 at the HQ location.
• EVC 2 between CE-1 and CE-3 must be provisioned with C-VLAN 13 at the HQ location.
Which configuration must the network engineer implement on the PE routers to provide end-to-end Carrier Ethernet service to the customer?

Refer to the exhibit. OSPF is running in the network, which is segmented into three areas. MPLS is enabled on all routers to support Layer 3 VPN. The network architect is concerned about potential packet loss when new OSPF adjacencies form. Which two tasks should the architect perform to implement MPLS LDP synchronization? (Choose two.)
