• Question 243:

  Refer to the exhibit.

  

  Multicast traffic destined from T1 and T2 routers to RP routers works well. A network engineer observes problems with multicast traffic flows between Site-A and Site-B. Site-A users fail to receive multicast stream on Site-B via RPTY site, while Site-B users fail to receive multicast stream on Site-Avia RPTZ site.

  Which action must be implemented to resolve the issues?

  A. Establish MDSP peering with interface IP subnet.
  B. Configure Site-A and Site-B in 10.80.14804
  C. Allow the OSPF and MSDP packets on the firewall.
  D. Configure direct OSPF peering between Site-A and Ste-B
  C. Allow the OSPF and MSDP packets on the firewall.

• Question 244:

  Which attribute is used to instruct the router that packets must be processed by an ASA that is associated with the segment?

  A. service SID with service instructions
  B. node SID that identifies a specific network device
  C. prefix SID that represents a specific route prefix
  D. adjacency SID with unidirectional adjacency instructions
  B. node SID that identifies a specific network device

• Question 245:

  Which two statements about mapping multicast IP addresses to MAC addresses are true? (Choose two.)

  A. All mapped multicast MAC addresses begin with 0x0100.5E
  B. The router performs the mapping before it hands the packet off to a switch
  C. All multicast MAC addresses end with 0x0100.5E
  D. The mapping process may generate overlapping addresses, which can cause receivers to receive unwanted packets
  E. All destination MAC addresses begin with an octet of binary 1s
  A. All mapped multicast MAC addresses begin with 0x0100.5E
  D. The mapping process may generate overlapping addresses, which can cause receivers to receive unwanted packets

• Question 246:

  Refer to the exhibit.

  

  Excessive routes are flooding from network 150.0.0.0 into AS100. Internet traffic between AS400 and AS300 is working normally. No route controlling mechanism is applied on incoming and outgoing traffic Which configuration resolves the issue?

  

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

• Question 247:

  Refer to the exhibit.

  

  IS-IS runs in the network, and all routers are in the same area. R1 uses static routes to distribute traffic to R6, and the networking team has redistributed the static routes on R1 into IS-IS. Hosts on R3 need access to servers connected to R6. A tag has been applied to the routes to manipulate the path, but routers running IS-IS are still unable to reach the redistributed routes. Which action must the team take to resolve the issue?

  A. Configure the routers as Level 1/Level 2 routers.
  B. Configure R3 with a default route that uses R2 as the next hop.
  C. Configure the IS-IS routers with metric-style wide.
  D. Configure the route-map with an additional route-map set-tag permit 10 sequence.
  C. Configure the IS-IS routers with metric-style wide.

• Question 248:

  How does the SRv6 IS-IS Flexible Algorithm function on the data plane?

  A. It uses the TE metric in its path calculations to optimize the cumulative TE metric.
  B. It uses the IGP metric in its path calculations to optimize reachability.
  C. It automatically delivers traffic to the destination over an engineered path computed by the IGP.
  D. It applies path computation algorithms to learn the topology and compute a pair of disjoint LSPs.
  C. It automatically delivers traffic to the destination over an engineered path computed by the IGP.

• Question 249:

  Refer to the exhibit.

  

  After troubleshooting an OSPF adjacency issue, routers 1, 2, and 3 have formed OSPF neighbor relationships. Which statement about the configuration is true?

  A. Router 2 receives a Type 5 LSAs from router 1 for its connected subnets
  B. Router 2 uses router 3 as the next hop for 192.168.0.0/24
  C. Router 2 uses router 1 as the next hop for 192.168.0.0/24
  D. Router 2 receives a Type 7 LSAs from router 3 for its connected subnets
  C. Router 2 uses router 1 as the next hop for 192.168.0.0/24

  Explanation Explanation/Reference:From IOS 15.1(2)S onwards, Cisco uses the OSPF path selection order is O > O IA > N1 > E1 > N2 > E2 https://www.cisco.com/c/en/us/support/docs/ip/open-shortest- path-first-ospf/212608-ospf-external-path-selection-external-t.html

• Question 250:

  Refer to the exhibit.

  

  OSPF is an interior routing protocol on the network. Routers R4 and R6 are in area 0, and all tunnels are in area 2. R4 is connected to R6 with a 1 Gbps link and with 100 Mbps links to the rest of the LAN. After the most recent maintenance window, a network engineer noticed that R4 is using a suboptimal route toward 10.173.12.10 instead of the route via R6. Which action must the network engineer take to correct reachability toward 10.173.12.10/24?

  A. Configure auto-cost reference-bandwidth 1000 under the global OSPF configuration on R4.
  B. Configure ip ospf 0 area 0 under tunnel 2 on both R4 and R5.
  C. Configure ip ospf cost 120 under the Gi0/0 interface on R4.
  D. Configure ip ospf 2 area 0 under tunnel 3 on both R6 and R5.
  A. Configure auto-cost reference-bandwidth 1000 under the global OSPF configuration on R4.
