Q48. What is the way that an OSPF ABR uses to prevent summary route information from being readvertised from an area into the network core (Area 0)?

Q49. You are redesigning an OSPF v2 network and must migrate some links. You are concerned that there are different subnet masks. Which two link types will still form an
OSPF adjacency even if there are subnet mask mismatches? (Choose two.)

Q50. Refer to the exhibit.

An enterprise is migrating its single-area OSPF network from a Frame Relay WAN service to an MPLS L3VPN service. Frame Relay will remain in only a few sites that require increased resiliency via two different WAN connections.
Which feature could be used in the ?MPLS VPN service provider network to support the design requirement by ensuring that during normal operation, intersite traffic will only use the MPLS VPN service and not the old Frame Relay service?

Q51. On a large-scale DMVPN network design, what are two DMVPN characteristics? (Choose two.)

Q52. The network designer needs to use GLOP IP address in order make them unique within their ASN, which multicast address range will be considered?

Q53. Refer to the exhibit.

You must review this single OSPF area, DMVPN network because the company has noticed a few area 0 convergence and stability issues. Also, traffic destined to the data center from one of the spokes as the next hop on the path. The company prefers that all traffic destined to the data center uses the least amount of hops. Which solution resolves these issues with the minimum amount of changes on the network?

Q54. Which encoding format does cisco ios XE software support for NETCONF?

Q55. Drag and drop the NETCONF layers on the left to the correct descriptions on the right

Q56. Refer to the exhibit.

Your company designed a network to allow server VLANs to span all access switches in a data center. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches. Which two features will improve STP stability within the network design? (Choose two.)

Q57. VPLS is implemented in a Layer 2 network with 2000 VLANs. What is the primary concern to ensure successful deployment of VPLS?

Q58. To meet specific business requirements, QoS-marked traffic must be sent over a dedicated link. Which technology fulfills this requirement?

Q59. A senior network designer suggests that you should improve network convergence times by reducing BGP timers between your CE router and the PE router of the service provider.
Which three factors should you to consider when you adjust the timer values? (Choose three.)

Q60. When a multiprotocol environment is designed to have several routers redistribute among the routing domains, how can routing loops be avoided?

Q61. Refer to the exhibit You are designing this network to support voice communication between software and hardware endpoints To ensure quality, the decision is to implement a DiffServ QoS model with priority queuing Which admission criteria option do you recommend?

Q62. Refer to the exhibit. A customer currently has a large EIGRP based network with several remote sites attached. All remote sites connect to the two Corporate data centers, depicted as 10.1.1.0 and 10.1.2.O. The customer has experienced several network wide failures where neighbours were stuck in active and had other network stabilitty issues due to some links flapping. Which two redesign options increase network stability and reduce the load on the remote site routers, while still maintaining optimal routing between remote sites and the two data centers? (Choose two)
