Refer to the exhibit. Four midsize service providers provide access to different customers that use Layer 3 VPN services to enable communication across geographic regions. The service providers are connected as shown in the exhibit, and the PEs have established eBGP relationships. PE4 has an IBGP relationship with PE5. The routes that PE4 learns from PE5 must reach the other PE routers, but they are absent from the routing tables on the other PES. Which action should the engineers take to correct the problem?
Configure a peering between all five Pes.
Disable BGP synchronization on PE4.
Enable BOP IPv4 unicast on PE4 and PE5
Advertise the route targets for PE5 to the other PEs
Which feature describes the weight parameter for BGP path selection?
Its value is local to the router
Its value is set either locally or globally.
Its default value is 0.
Its value is global to the router.
Refer to the exhibit.
Refer to the exhibit. A company recently deployed a new network using OSPF in the core to share routes. The network administrator selected OSPF as the routing protocol because of its ability to maintain a route database. When the new network was started up, all routers booted normally, but the link between routers R1 and R2 failed to come up. The two routers are located in the same rack at the data center. Which task should an engineer perform to correct the problem?
Synchronize the dead timers.
Change one of the OSPF router IDs so that the router IDs are in different subnets
Change the OSPF process ID on one of the devices so that the two IDs match
Configure the MTUs on the interface to match.
What is a characteristics of the Pipe model for MPLS QoS?
The same QoS policy is applied to all customer traffic on the egress PE.
If the outer EXP is changed, it is copied to the DSCP value.
The MPLS EXP bits are set by the CE.
The DSCP value determines how the packet is forwarded
Refer to the exhibit.
Refer to the exhibit. An engineer configured several network devices to run REST APIs. After testing, the organization plans to use REST APIs throughout the network to manage the network more efficiently. What is the effect if this script?
It returns an AAA users with the last name CiscoTest.
It creates a class map named aaauser with traffic tagged from AAA.
It queries the local database to find a user named aaaUser.Json
It adds the user CiscoTest to the AAA database located at 192.168.201.10.
Refer to the exhibit.
Refer to the exhibit. The network operations team reported that the access site that is connected to R3 is not connecting to the application server in the data center and that all packets that are sent from the application server to the access site are dropped. The team verified that OSPF and BGP peerings are up in BGP AS 65101 and BGP AS 65201. R4 is expected to receive traffic from the application server route via OSPF. Which action resolves this issue?
Remove the route-map on R4 when advertising 172.16.20.1 in BGP to R3.
Advertise application server 172.16.20.1 in the OSPF routing table on R6.
Allow 172.16.20.1 in the BGP advertisement on R3 in the route-map.
Add the next-hop-self command on R6 to enable R3 iBGP peering.
Refer to the exhibit.
Refer to the exhibit. A global company plans to implement BGP at its newest location to provide connectivity to other offices. The global infrastructure of the company is a multivendor environment. An engineer must review the BGP core configurations at headquarters to determine if they can be repurposed at the new location. The engineer copied this JSON script for review. What is the effect of the script?
It configures BGP with neighbor 192.168.1.2 residing in AS 65514.
It sets the BGP router-ID to 192.168.1.2 and sets the AS of the router to 65514.
It configures BGP on the device and inserts 192.168.1.0/24 into the BGP table using the origin AS 65514.
It configures a VRF named cisconode1 and a BGP instance using the VPNv4 address family.
Refer to the exhibit.
Refer to the exhibit. An engineer must Implement a traceroute operation to verity the R1 point-to-multipoint LSP connections. The traceroute operation must return all labels and hop-by-hop IP addresses for destinations 10.20.0.1. 10.30.0.1, and 10.40.0.1. and the maximum number of hops is 4. Which command must be executed to meet the requirements?
traceroute mpls traffic-eng tunnel-mte 10 ttl 4
traceroute mpls traffic-eng tunnel-mte 10 responder-id 10.40.0.1
traceroute mpls ipv4 10.30.0.1/32 fee-type generic
traceroute mpls ipv4 10.20.0.1/32 ttl 4
Refer to the exhibit.
Refer to the exhibit. Tier 1 ISP A purchased several Tier 2 ISPs to increase their customer base and provide more regional coverage. ISP A plans to implement MPLS services in the access layer, with scalability up to 100.000 devices In one packet network and service recovery up to 50 ms. The network architect decided to use different independent IGP and LDP domains and interconnect LSPs that are based on RFC 3107. Which two actions must the network engineer perform to meet the requirements? (Choose two.)
Implement BGP PIC core functionality on routers R2 and R3.
Configure three OSPF areas, with Area 0 In the core domain, and Areas 2 and 3 in the aggregation domain.
Implement BGP connectivity between routers R1 and R4 with VPNv4 address family enabled.
Implement BGP inline RR functionality with next-hop-self capabilities on routers R2 and R3.
Implement the IS-IS routing protocol on the access domain.
Refer to the exhibit.
Refer for the exhibit. To optimize network operations, the senior architect created this Python 3.9 script for network automation tasks and to leverage Ansible 4.0 playbooks. Devices In the network support only RFC 2617-based authentication What does the script do?
The script logs in via SSH and configures interface GigabitEthernetO/1 with IP address 10.1.131.112/30.
The script leverages REST API calls and configures Interface GlgabilEthemet0/1 with IP address 10.1.131.112/30.
The script performs a configuration sanity check on the device with IP address 172.168.211.65 via HTTP and returns an alert If the payload field falls to match.
The script parses the JSON response from the router at IP address 172 168.211.65 and checks If the interface GigaWtEthernet0/1 with IP address 10.1.131.112 exists on the router.
