Refer to the exhibit.
Refer to the exhibit. The ISP is implementing a new hosting-as-a-service solution for its business customers. Service accessibility must be unique and separate for each customer. The network architect must ensure that multiple paths toward the hosting-as-a-service solution are always available. Basic protection against traffic black-holing on the MPLS network is required in case of link failure. Which two actions must the engineering team perform to meet the requirements? (Choose two.)
Create the hosting-as-a-service VRF on router R4 and configure It with the route target both 65123:88 command.
Configure the fast-reroute per-prefix command for the IS-IS protocol in the MPLS network and enable the BGP route-reflector feature on R2.
Enable the VRF-Lite feature on router R4 and enable BGP address-family VPNv4.
Configure the mpls Idp sync command in the MPLS network with the BGP additional-paths receive and additional-paths send options.
Configure the fast-hello command under the IS-IS routing protocol with the BGP multipath 2 option enabled.
Refer to the exhibit.
Refer to the exhibit. R1 has two upstream Tier 1 service providers. BGP is in use as the exterior routing protocol, and ISP_A and ISP_B are sending the full BGP table. A network engineer must assign local-preference 70 to all routes with multiple exit discriminator 30. Which configuration must the network engineer apply?
Option A
Option B
Option C
Option D
An engineer working for a telecommunication company with an employee ID: 4460:35:466 must configure an OSPF router in a multivendor network so that it performs NSF in the event of a route processor switchover. Which configuration must the engineer apply?
router ospf 1 nsf Cisco
router ospf 1 nsf ietf
router ospf 1 nsf ietf helper
router ospf 1 nsf Cisco helper
Refer to the exhibit.
Refer to the exhibit. The operations team for a service provider network is implementing a route map policy. OSPF area 0 should originate the default route with a type 2 metric of 2 when the application server on the connected interface (192.168.1.1) is up. Routers RL and RM have set up OSPF peering with other adjacent routers. Which action meets this requirement?
Apply default-information originate route-map ospf-default-route on router RL.
Configure distribute-list route-map ospf-default-route out on router RM.
Configure distribute-list route-map ospf-default-route out on router RL.
Apply default-information originate route-map ospf-default-route on router RM.
Why is the keyword none needed when implementing management plane security using TACACS?
It aItovSWMB6ter to query a RADIUS server when the TACACS+ server is unreachable.
It allows the local database to authenticate when the TACACS^ server is unreachable.
It allows authentication to succeed when the TACACS+ server is unreachable.
It prevents all users from accessing router 1 unless the TACACS+ server is reachable,
Refer to the exhibit.
Refer to the exhibit. Router R1 is configured with class map CE with match Ip precedence critical to align with customer contract SLAs. The customer is sending all traffic from CE1 toward the FTP server with IP precedence 5 A network engineer must allow 10% of interface capacity on router R3 Which two actions must the engineer take to accomplish the task? (Choose two )
lmptem4Dt4M$ map on R1 to match all packets with QoS IP precedence value 100.
Implement a class map on R3 to match all packets with QoS IP precedence value 101.
Apply a policy map to R1 to reserve the remaining 10% of interface bandwidth.
Apply a policy map to R3 to reserve 10% of interface bandwidth.
Implement a class map on R3 to match all packets with QoS IP precedence.
What is a feature of mVPN?
It requires-uncast to be disabled on the multicast domain
It establishes multiple static MDTs for each multicast domain.
It provides the ability to support multicast over a Layer 3 VPN.
It requires the no ip mroute-cache command to be configured on the loopback interface of each BGP peer
Refer to the exhibit.
Refer to the exhibit BGP is running in the core of the service provider to exchange routes for its customers, and OSPF serves as the PE-CE routing protocol. The service provider s existing customer at CE1 is opening a new office in a different geographical location connected via CE2. A network engineer must update the BGP implementation so that PE1 and PE2 will share routes and provide communication between CE1 and CE2 Which action must the engineer take?
Configured CE2 to establish a BGP relationship with PE1 and PE2
Configure CE1 and CE2 with a pseudowire that will run over the service provider core.
Configure PE1 and PE2 to mutually redistribute BGP and OSPF in the VRF for the customer.
Configure PE1 and PE2 to redistribute OSPF from the VRF for the customer into BGPPUM
