DRAG DROP -
A network engineer is adding an additional 10Gbps link to an existing 2x10Gbps LACP-based LAG to augment its capacity. Network standards require a bundle interface to be taken out of service if one of its member links goes down, and the new link must be added with minimal impact to the production network. Drag and drop the tasks that the engineer must perform from the left into the sequence on the right. Not all options are used.

Bvirtual link between RB and RC
Csham link
Ddefault route
Refer to the exhibit. Router 1 and router 2 are running IBGP, and router 2 and router 3 are running OSPF Area 0. Router 1 is advertising loopback interfaces Lo 0 and Lo 2, and router 2 is redistributing BGP into OSPF Area 0. Which configuration must an administrator apply so that router 2 uses a route map to redistribute only the internal route from Lo 2?
Refer to the exhibit. An engineer is configuring path selection on router R1 for two ASNs as shown. Which additional task must the engineer perform on Router 1 so that all outbound traffic utilizes the link between R1 and R3 to reach ASN 4567?
AConfigure a low weight on the peer to ASN 4567.
BConfigure a high weight on the peer to ASN 4567.
CConfigure an AS path prepend on the peer to ASN 4567.
DConfigure a high med on the peer to ASN 4567.
Refer to the exhibit. Router BRDR-1 is configured to receive the 0.0.0.0/0 and 172.17.1.0/24 networks via BGP and advertise them into OSPF area 0. An engineer has noticed that the OSPF domain is receiving only the 172.17.1.0/24 route and default route 0.0.0.0/0 is still missing. Which configuration must an engineer apply to resolve the problem?
Drouter ospf 1 default-information originate always end
Refer to the exhibit. Router R1 is reporting that its BGP neighbor adjacency to router R2 is down, but its state is Active. Which configuration must be applied to routers R1 and R2 to fix the problem?
Refer to the exhibit. A network operator is attempting to configure an IS-IS adjacency between two routers, but the adjacency cannot be established. To troubleshoot the problem, the operator collects this debugging output.
Which interfaces are misconfigured on these routers?
AThe R2 interface is configured as point-to-point, and the peer router interface is configured as multipoint.
BThe R2 interface is configured as Level 1 only, and the peer router interface is configured as Level 2 only.
CThe peer router interface is configured as point-to-point, and the R2 interface is configured as multipoint.
DThe peer router interface is configured as Level 1 only, and the R2 interface is configured as Level 2 only.
Refer to the exhibit. An engineer has started to configure a router for OSPF, as shown. Which configuration must an engineer apply on the network so that area 15 traffic from R5 to R1 will prefer the route through R4?
AImplement a sham link on the link between R3 and R2 to extend area 0 over area 15.
BImplement a multiarea adjacency on the link between R2 and R4, with the cost manipulated to make the path through R4 preferred.
CPlace the link between R3 and R5 in a stub area to force traffic to use the route through R4.
DIncrease the cost on the link between R2 and R3 to a value higher than the link between R2 and R4, to influence the path over R3 and R4.
Refer to the exhibit. An engineer is configuring multitopology IS-IS for IPv6 on router R1. Which additional configuration must be applied to the router to complete the task?
Refer to the exhibits. Which information is provided for traceback analysis when this configuration is applied?
Asource interface
Bpacket size distribution
CIP sub flow cache

AThe routing policy is absent for this Cisco IOS XR eBGP instance.
BThe TCP session parameters are not specified.
CThe VPNv4 address family interferes with the BGP IPv4 address family negotiations.

Refer to the exhibit. An engineer is implementing BGP selective prefix suppression. The router must advertise only 10.16.4.0/24, 10.16.5.0/24, and summarized route 10.16.0.0/21, and suppress 10.16.6.0/24. Which configuration must the engineer apply to the router?
Refer to the exhibit. Which BGP attribute should be manipulated to have CE1 use PE1 as the primary path to the internet?
AThe local preference attribute should be manipulated on PE2 on inbound and outbound routes advertised to CE1.

CThe MED attribute should be manipulated on CE1 on inbound routes from PE1.
DThe weight attribute should be manipulated on PE1 on outbound routes advertised to CE1.
Refer to the exhibit. CE1 and CE2 require connectivity to the internet through the ISP connected to PE3. What should an engineer configure to complete this task?
ACE1 and CE2 must be configured with a route distinguisher in the PE1 VRF that dynamically imports the route from the internet.
BCE1 and CE2 must be configured to use a static default route with a next-hop of PE3 to reach internet routes.
CPE1 must be configured with an import route target in the CE1 VRF that matches the export route target for the internet VRF on PE3.
DPE2 must be configured to serve as a route reflector for PE3 routes learned from the internet. PE2 then shares the routes with CE1 and CE2.
Refer to the exhibit Which effect of this configuration is true?
AR1 can support a peer that is configured for LDP SSO/NSF as the peer recovers from an outage.
BR1can support a graceful restart operation on the peer, even if graceful restart is disabled on the peer.
CR1 can failover to any peer.
DR1 can failover only to a peer that is configured for LDF SSO/NSF.
Refer to the exhibit. R1 is connected to two service providers and is under a DDoS attack.
Which statement about this design is true if URPF in strict mode is configured on both interfaces?
AR1 drops all traffic that ingresses either interface that has a FIB entry that exits a different interface.
BR1 drops destination addresses that are routed to a null interface on the router.
CR1 permits asymmetric routing as long as the AS-PATH attribute entry matches the connected AS.
DR1 accepts source addresses on interface gigabitethernet0/1 that are private addresses.
