In the service provider network, routers PE1, PE2, and PE4 have access to the internet and provide access to customer networks. Router PE3 is used for access to other customer systems. In accordance with a new SLA, an engineer is updating settings on this network so that router CE1 accesses the internet via PE1 instead of PE2. Which two tasks must the engineer perform to complete the process? (Choose two.)
On PE1, configure the internet VRF with import route target 102:102.
On PE1 and PE4, configure the internet VRF with import route targets 102:102 and 104:104.
On PE2, configure the internet VRF with import route target 102:102.
On PE2 and PE3, configure the internet VRF with import route target 101:101.
On PE2, configure the CE1 VRF with import route target 101:101.

A NOC engineer is configuring label-based forwarding from CSR to the EPC gateway. Cell-site operation and maintenance for IPv4 traffic between 10.20.10.1 and 192.168.10.10 is already up. CR1 and CR2 are configured as route reflectors for AG1 and AG2. Which action completes the configuration?
Remove address-family labeled-unicast from the BGP session-group infra on AG1 for neighbor-group core.
Apply the BGP_Egress_Filter route policy to the BGP neighbor-group packet core on AG1.
Configure AG1 to allocate a label to the BGP routes that are received in the BGP session group transport.
Configure AG1 to allow the 300:100 and 200:100 communities in the BGP_Egress_Filter route policy.
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.

Configure and verify the OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals:
Establish R1 and R2 OSPF adjacency. All interfaces must be advertised in OSPF by using the OSPF interface command method. Use Loopback0 as the OSPF ID.
There must be no DR/BDR elections in OSPF Area 0 when establishing the neighbor relationship between R1 and R2. OSPF must not generate the host entries /32 for the adjacent interfaces.
Enable OSPF MD5 Authentication between both routers at the interface level with password C1sc0!.

An engineer at a new ISP must configure many Cisco devices in the data center. To make the process more efficient, the engineer decides to automate the task with a REST API. Which action does this JSON script automate?
Configure the IP address for the existing loopback interface.
Configure a physical interface on the router with an IP address and then create a loopback interface.
Configure a physical interface on the router with an IP address.

What Is one of the differences between Ansible and Chef?
Ansible uses YAML and Chef uses Ruby.
Chef requires the use of Windows in the environment and Ansible requires Linux.
Chef is highly scalable and Ansible is highly secure.
Ansible uses Ruby and Chef uses Python.

A network engineer must configure an LDP neighborship between two newly installed routers that are located in two different offices. Router 1 is the core router in the network and it has already established OSPF adjacency with router 2. On router 1 and router 2. interface fa0/0 is configured for BFD. Which additional configuration must the engineer apply to the two devices to meet the requirement?
Router1(config)#int fa0/0 -
Router1(config-if)#mpls ldp autoconfig
Router2(config)#router ospf 1 -
Router2(config-router)#mpls ip
Router1(config)#int fa0/0 -
Router1(config-if)#mpls ip -
Router1(config-if)#mpls ldp discovery transport-address interface
Router2(config)#int fa0/0 -
Router2(config-if)#mpls ip -
Router2(config-if)#mpls ldp discovery transport-address interface
Route1(config)#int fa0/0 -

Configure the BGP routing protocol for R1 and R2 according to the topology to achieve these goals:
Configure EBGP neighbor adjacency for the IPv4 and IPv6 address family between R1 and R2 using Loopback0 IPv4 and IPv6 addresses. All BGP updates must come from the Loopback0 interface as the source. Do not use IGP routing protocols to complete this task.
Configure MD5 Authentication for the EBGP adjacency between R1 and R2. The password is clear text C1sc0!.
