• Question 262:

  The administrator of a small company network notices that intermittent network issues occasionally cause inbound notifications to its SNMP servers to be lost.

  Which configuration must the administrator apply so that the SNMP servers acknowledge the notifications that they receive?

  A. snmp-server community ciscotest rw 10
  B. snmp-server host tests.cisco.com publicsnmp-server community ciscotest rw 10
  C. snmp-server enable traps bgpsnmp-server host 192.169.2.1 Informs
  D. snmp-server enable traps snmp
  C. snmp-server enable traps bgpsnmp-server host 192.169.2.1 Informs

  ---

  Explanation

  The correct configuration to ensure that SNMP servers acknowledge the notifications they receive is to use the snmp-server host command with the Informs keyword. This configuration sends Inform requests instead of Trap messages. Unlike Traps, Inform requests are acknowledged by the receiving SNMP server, ensuring that the notification has been received. If an Inform request is not acknowledged, the SNMP agent resends the notification.

  The information is based on the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) training, which teaches how to configure, verify, troubleshoot, and optimize next- generation, Service Provider IP network infrastructures.

• Question 265:

  Refer to the exhibit.

  

  The application server in the data center hosts voice, video, and data applications over the internet. The data applications run more slowly than the voice and video applications. To ensure that all applications run smoothly, the service provider decided to implement a QoS policy on router PER 2 to apply traffic shaping.

  Which two actions must an engineer take to implement the task? (Choose two.)

  A. Configure the scheduling function to handle delayed packets.
  B. Enable packet remarking for priority traffic.
  C. Configure a queue to buffer excess traffic.
  D. Set the token value for secondary traffic.
  E. Set a threshold to discard excess traffic.
  A. Configure the scheduling function to handle delayed packets.
  C. Configure a queue to buffer excess traffic.

• Question 266:

  Refer to the exhibit.

  

  An engineer is configuring router R1 for OSPFv3 as shown.

  Which additional configuration must be performed so that the three active interfaces on the router will advertise routes and participate in OSPF IPv6 processes?

  A. R1(config)# interface Ethernet1/1R1(config-if)# ipv6 ospf 100 area 0R1(config)# interface Ethernet1/2R1(config-if)# ipv6 ospf 100 area 10R1(config)# interface Ethernet1/3R1(config-if)# ipv6 ospf 100 area 20
  B. R1(config)# interface Ethernet1/1R1(config-if)# ip ospf hello-interval 1R1(config-if)# ipv6 ospf 100 area 0R1(config)# interface Ethernet1/2R1(config-if)# ip ospf hello-interval 1R1(config-if)# ipv6 ospf 100 area 10R1(config)# interface Ethernet1/3R1(config-if)# ip ospf hello-interval 1R1(config-if)# ipv6 ospf 100 area 20
  C. R1(config)# interface Ethernet1/1R1(config-if)# ipv6 ospf 1 area 0R1(config)# interface Ethernet1/2R1(config-if)# ipv6 ospf 1 area 10R1(config)# interface Ethernet1/3R1(config-if)# ipv6 ospf 1 area 20
  A. R1(config)# interface Ethernet1/1R1(config-if)# ipv6 ospf 100 area 0R1(config)# interface Ethernet1/2R1(config-if)# ipv6 ospf 100 area 10R1(config)# interface Ethernet1/3R1(config-if)# ipv6 ospf 100 area 20

• Question 267:

  Refer to the exhibit.

  

  An engineer at a new ISP must configure many Cisco devices in the data center. To make the process more efficient, the engineer decides to automate the task with a REST API.

  Which action does this JSON script automate?

  A. Configure the IP address for the existing loopback interface.
  B. Configure a physical interface on the router with an IP address and then create a loopback interface.
  C. Configure a physical interface on the router with an IP address.
  D. Delete the existing loopback Interface and replace it with a new loopback interface.
  A. Configure the IP address for the existing loopback interface.

• Question 268:

  Refer to the exhibit.

  

  A network administrator wants to enhance the security for SNMP for this configuration.

  Which action can the network administrator implement?

  A. Add a community string to the existing entry.
  B. Maintain the configuration but switch to an encrypted password for device access through SSH.
  C. Re-configure to use SNMPv2 with MD5 authentication.
  D. Re-configure to use SNMPv3.
  D. Re-configure to use SNMPv3.

  ---

  Explanation

  SNMPv3 is the most secure version of SNMP, providing both security and remote configuration capabilities. The current configuration in the exhibit shows SNMP version 2c, which is less secure. SNMPv3 introduces security features such as authentication, privacy (encryption), and access control to address the vulnerabilities associated with earlier versions of SNMP. By re-configuring to use SNMPv3, the network administrator can enhance the security for SNMP for this configuration.

• Question 269:

  FRR is configured on a network. What occurs when the headend router on the path is alerted to a link failure over IGP?

  A. LSP attempts fast switching on the backup path until the primary path returns to the active state.
  B. The headend router uses a presignaled LSP to bypass the failure point.
  C. A new backup tunnel is established past the PLR to pass through the protected nodes.
  D. Backup tunnel is established and intersects with the primary tunnel at the headend.
  B. The headend router uses a presignaled LSP to bypass the failure point.

• Question 270:

  Refer to the exhibit.

  

  A client wants to filter routes to a BGP peer to limit access to restricted areas within the network. The engineer configures the route map ciscotest to filter routes from the BGP neighbor. The engineer also sets a tag that will be used for QoS in the future.

  Which task must be performed to complete the implementation?

  A. Create a route map, configure BGP with an IPv4 address family, and activate the neighbor.
  B. Attach the new route map to the BGP neighbor statement in the inbound direction.
  C. Create a policy map named ciscotest and apply it to inbound traffic on the link that is directly connected to the BGP neighbor.
  D. Add a route map statement with sequence 40 that links a BGP community to the routing protocol.
  B. Attach the new route map to the BGP neighbor statement in the inbound direction.

  ---

  Explanation

  To complete the implementation of the route map "ciscotest" for filtering routes to a BGP peer, the engineer must attach the route map to the BGP neighbor statement in the inbound direction. This will apply the specified filtering criteria to routes received from the BGP neighbor, thereby limiting access to restricted areas within the network as intended by the client.

  References: The Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) course materials discuss the configuration of route maps and their application to BGP neighbors for route filtering purposes
