An MPLS core network has connectivity issues R4 has failed. It impacts traffic loss between R1 and R8. Customers report no access to their file servers, which delays their transformation work. Which quick action resolves the issue until R4 recovers?

Implement Link and Node protection on routers R2 and R7.
Disable traffic engineering so that traffic prefers the IGP path
Enable MPLS " fast reroute on router R1 and Link and Node protection on router R2.
Configure IBGP full mesh for faster convergence.

For which reason can two BGP peers fail to establish a neighbor relationship?
Their BGP send-community strings are misconfigured
Their BGP timers are mismatched
Their remote-as numbers are misconfigured
They are both activated under an IPv4 address family

Refer to the exhibit.
An engineer working on a client s network is trying to solve the BGP community issue on R1 and R2 routers. After displaying the BGP entries, the engineer notices that both routers still have different outputs. Which action must the engineer perform to any of the routers to correct the problem and get the same output?

Execute the lp bgp-community new-format command in Router1.
Remove the lp bgp-community new-format command in Router1.
Advertise the route to Router2 as standard community.
Advertise the route to Router2 as extended community.

What is the difference between a source tree and a shared tree in a multicast environment?
To route traffic from source to receiver a source tree uses a link-state routing protocol and a shared tree uses a distance-vector routing protocol.
A source tree has its root at the source, and a shared tree has its root at a designated rendezvous point.
To stream multicast from source to receiver, a source tree uses PIM-SM and a shared tree uses PIM-DM.
Source trees are the default type for bidirectional PIM, and PIM-DM uses shared trees by default.

Refer to the exhibit. An engineer applied the configuration on R1 to prevent network 192.168.1.0/24 from being propagated outside of area 5. After the change, users have reported they are not able to access any of the application servers that were working before. While checking the routing table of the peer router, the engineer notices R1 stopped propagating any routes outside area 5. Which action must be taken to fix the problem?
Change the prefix-list action to permit and add an explicit deny statement for network 192.168.1.0/24
Add a permit statement for 0.0.0.0/0 le 32 to the end of the prefix-list to override the implicit deny
Reconfigure the filter-list statement to apply in the inbound direction
Configure an additional filter-list on R1 for inbound traffic to allow external routes into area 5

Refer to the exhibits. All links inside the network are configured at a default cost of one inside the fully converged OSPF domain. Given the configuration from XR1, which interface does traffic from XR1 that is destined to the loopback interface of XR6 select for the exiting interface?
Interface GigabitEthernet 0/0. The tie breaker of the path cost being lower. The node index priority does not impact this selection process.
Interface GigabitEthernet 0/1. The tie breaker of the path cost being lower. The node index priority does not impact this selection process.
Interface GigabitEthernet 0/0. The tie breaker of the node index priority is lower and trumps the path cost.
Interface GigabitEthernet 0/1. The tie breaker of the node index priority is lower and trumps the path cost.
Routing Protocols
Refer to the exhibit. Router 1 is connected to router 2 on interface TenGigE0/1. Which interface provides the alternate path to 172.16.200.9/32 when the link between router 1 and router 2 goes down?
TenGigE0/1 interface provides the alternate path
A backup path must be statically installed
TenGigE0/2 interface provides the alternate path
A primary path must be manually installed
