  The IT router is connected with the Sales and Marketing departments. The interfaces have been assigned to their respective VRFs to keep the two department routes isolated. Which configuration set must the IT router use for BGP to distribute routes for each department that maintains their own routing table for network isolation?

  A. router bgp 111 address-family ipv4 unicast neighbor 172.16.1.2 remote-as 111 neighbor 172.16.2.2 remote-as 111 neighbor 172.16.11.2 remote-as 111 neighbor 172.16.12.2 remote-as 111
  B. router bgp 111 address-family ipv4 vrf Marketing neighbor 172.16.1.2 remote-as 111 neighbor 172.16.2.2 remote-as 111 ! address-family ipv4 vrf Sales neighbor 172.16.11.2 remote-as 111 neighbor 172.16.12.2 remote-as 111
  C. router bgp 111 neighbor 172.16.1.2 remote-as 111 neighbor 172.16.2.2 remote-as 111 neighbor 172.16.11.2 remote-as 111 neighbor 172.16.12.2 remote-as 111

• Question 492:

  Refer to the exhibit.

  

  An engineer observes that every time the ICMP packet is lost at a polling interval, track 1 goes down, which causes unnecessary disruption and instability in the network. The engineer does not want the traffic to be rerouted if the loss of ICMP packets is negligible. If the packet loss is persistent for a longer duration, the track must go down and the traffic must be rerouted. Which action resolves the issue?

  A. Change the IP SLA schedule to run only at certain intervals.
  B. Increase the timeout value from 1000 to 1500.
  C. Define a delay timer under track 1.
  D. Increase the threshold value from 1000 to 1500.
  C. Define a delay timer under track 1.

• Question 493:

  What is a function of an end device configured with DHCPv6 guard?

  A. If it is configured as a server, only prefix assignments are permitted.
  B. If it is configured as a relay agent, only prefix assignments are permitted.
  C. If it is configured as a client, messages are switched regardless of the assigned role.
  D. If it is configured as a client, only DHCP requests are permitted.
  C. If it is configured as a client, messages are switched regardless of the assigned role.

  ---

  The DHCPv6 Guard feature blocks reply and advertisement messages that come from unauthorized DHCP servers and relay agents. Packets are classified into one of the three DHCP type messages. All client messages are always switched regardless of device role. DHCP server messages are only processed further if the device role is set to server. Further processing of server messages includes DHCP server advertisements (for source validation and server preference) and DHCP server replies (for permitted prefixes). If the device is configured as a DHCP server, all the messages need to be switched, regardless of the device role configuration.

• Question 494:

  Refer to the exhibit.

  

  In Cisco DNA Center, a network engineer identifies that BGP-learned networks are repeatedly withdrawn from peers.

  Which configuration must the engineer apply to resolve the issue?

  A. router bgp 100 bgp graceful-restart
  B. router bgp 100 bgp dampening
  C. route-map Dampening permit 10 set dampening 15 750 2000 60 router bgp 100 neighbor 10.140.212.5 route-map Dampening in
  D. route-map Dampening permit 10 set dampening 15 750 2000 60 router bgp 100 neighbor 10.140.212.5 route-map Dampening out
  B. router bgp 100 bgp dampening

• Question 495:

  Which function does LDP provide in an MPLS topology?

  A. It enables a MPLS topology to connect multiple VPNs to P routers.
  B. It provides hop-by-hop forwarding in an MPLS topology for LSRs.
  C. It exchanges routes for MPLS VPNs across different VRFs.
  D. It provides a means for LSRs to exchange IP routes.
  B. It provides hop-by-hop forwarding in an MPLS topology for LSRs.

  ---

  LDP provides a standard methodology for hop-by-hop, or dynamiclabel, distribution in an MPLS network by assigning labels to routes that have been chosen by the underlying Interior Gateway Protocol (IGP) routing protocols. The resulting labeled paths, called label switch paths (LSPs), forward label traffic across an MPLS backbone to particular destinations.

• Question 496:

  Refer to the exhibit

  

  The engineer configured route redistribution in the network but soon received reports that R2 cannot access 192 168 7 0/24 and 192 168 15 0/24 subnets Which configuration resolves the issue?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

• Question 497:

  Refer to the exhibit.

  

  R1 is configured with uRPF, and ping to R1 is failing from a source present in the R1 routing table via the GigatxtEthernet 0/0 interface. Which action resolves the issue?

  A. Remove the access list from the interface GigabrtEthernet 0/0
  B. Modify the uRPF mode from strict to loose
  C. Enable Cisco Express Forwarding to ensure that uRPF is functioning correctly
  D. Add a floating static route to the source on R1 to the GigabitEthernet 0/1 interface
  B. Modify the uRPF mode from strict to loose

  ---

  with uRPF strict mode, this can cause legitimate packets to be dropped, so that's something to keep in mind. In uRPF loose mode, the source of the IP packet must simply appear in the routing table. So loose mode looks for any interface in the routing table other than the default route.

• Question 498:

  Which two statements about redistributing EIGRP into OSPF are true? (Choose two)

  A. The redistributed EIGRP routes appear as type 3 LSAs in the OSPF database
  B. The redistributed EIGRP routes appear as type 5 LSAs in the OSPF database
  C. The administrative distance of the redistributed routes is 170
  D. The redistributed EIGRP routes appear as OSPF external type 1
  E. The redistributed EIGRP routes as placed into an OSPF area whose area ID matches the EIGRP autonomous system number
  F. The redistributed EIGRP routes appear as OSPF external type 2 routes in the routing table
  B. The redistributed EIGRP routes appear as type 5 LSAs in the OSPF database
  F. The redistributed EIGRP routes appear as OSPF external type 2 routes in the routing table

• Question 499:

  Refer to the exhibit.

  

  A customer finds that traffic from the application server (192.168.1.1) to the HUB site passes through a congested path that causes random packet drops. The NOC team influences the BGP path with MED on RB. but RD still sees that traffic coming from RA is not taking an alternate route. Which configuration resolves the issue?

  A. RD(config)#router bgp 65201 RD(config-router)#no neighbor 10.10.10.2 weight 65535
  B. RB(config)#router bgp 65101 RB(config-router)#no neighbor 10.10.10.3 route-map HIGH-LP out
  C. RB(config)#router bgp 65101 RB(config-router)#neighbor 10.10.10.3 weight 50
  D. RC(config)#router bgp 65101 RC(config-router)#neighbor 10.10.10.6 route-map HIGH-LP out
  D. RC(config)#router bgp 65101 RC(config-router)#neighbor 10.10.10.6 route-map HIGH-LP out
