Refer to the exhibit. Router 1 is a core ABR in a Cisco Unified MPLS environment. All of the router 1 BGP peers are established, but traffic between customers is failing. Which BGP configuration must be added to the configuration?
It must be configured with a route reflector
It must be configured with send labels
It must be configured with PIC edge

How does SRv6 direct packets through the data plane?
Single Choice
Refer to the exhibit. How are packets directed through the data plane when SRv6 is implemented?
An ordered list of segments is encoded in a routing extension header
The MPLS data plane is used to push labels onto IGP routes
A stack of labels represents an ordered list of segments
The packet is encapsulated with a header and trailer encoding the ordered list of segments

Refer to the exhibit. An engineer is troubleshooting an OSPF issue. Router 1 has a neighbor relationship with router 2. Only router 1 classful EIGRP routes can be seen on router 2. In order for all EIGRP routes to be redistributed correctly, which action should be taken?
Router 1 must have the keyword subnets included in the redistribution command for all EIGRP routes to be redistributed.
Router 1 must remove the AS number 1 from the redistribution command for all EIGRP routes to be redistributed.
Router 1 must have the keyword ospf-metric included in the redistribution command for all EIGRP routes to be redistributed.
Router 1 must have the keyword metric-type 1 included in the redistribution command for all EIGRP routes to be redistributed.

Refer to the exhibit. Routers R1, R2, R3, and R4 have been configured to run OSPF, and router R5 is running EIGRP. Traffic from R1 to R5 is expected to pass via R4, but OSPF routing has calculated the best path R3. Which action corrects the problem?
Reconfigure R1 in Area 0
Configure R3 to use metric-type 1 with a higher metric than R4
Configure R1 with a static route to the R5 networks and set R5 as the next hop
Change the metric-type value on R3 to 2

R1 is expected to receive routes originating from AS 65516 and from any ASs that are directly attached to it. However, R1 is receiving routes only from AS 65516. Which action corrects the configuration?

Change the regular expression in the AS-path permit filter to .*.
Change the regular expression in the AS-path permit filter to ^65516_[0-9]*$.
Add the regular expression ^$. in the AS-path filter to permit the traffic from R2.
Change the regular expression in the AS-path permit filter to _65516_.

Routers R1 and R2 reside in AS 65530, which is multihomed to the Internet. A network engineer expects devices in the AS to use R2 to access the Internet, but they are using R1 as the exit point from the AS. Which action corrects the problem?

Add a sequence number to the route map to remove the implicit deny.
Change the route map direction in the neighbor statement to out.
Configure the route map with a local preference of 200 or higher.
Remove the neighbor statements from the address family configuration and activate the neighbor globally on R1.

What are two features of dual-stack in networking?
Multiple Choice
What are two features of dual-stack? (Choose two.)
It is implemented without excessive processing power.
It supports IPv4 and IPv6 traffic on the same infrastructure.
It allows an engineer to stack multiple Layer 2 switches to serve as a single switching unit.
It requires tunneling IPv6 traffic over an IPv4 infrastructure.
It securely routes and tunnels traffic between separate sites over the Internet.
