• Question 93:

  Refer to the exhibit.

  

  A network engineer is deploying SNMP configuration on client's routers. Encrypted authentication must be included on router 1 to provide security and protect message confidentially.

  Which action should the engineer perform on the routers to accomplish this task?

  A. snmp-server host 192.168.0.254 informs version 3 auth testuser config.
  B. snmp-server user testuser group 1 remote 192.168.0.254 v3 auth md5 testpassword
  C. snmp-server group group 1 v3 auth.
  D. snmp-server community public
  B. snmp-server user testuser group 1 remote 192.168.0.254 v3 auth md5 testpassword

  ---

  Explanation

  For encrypted authentication on Router 1, the correct action is to configure an SNMP user with an authentication password and associate it with a group. Option B includes the use of MD5 authentication, which provides the required security for message confidentiality.

• Question 94:

  Refer to the exhibit.

  

  

  A NOC engineer is configuring label-based forwarding from CSR to the EPC gateway. Cell- site operation and maintenance for IPv4 traffic between 10.20.10.1 and 192.168.10.10 is already up. CR1 and CR2 are configured as route reflectors for AG1 and AG2.

  Which action completes the configuration?

  A. Remove address-family labeled-unicast from the BGP session-group infra on AG1 for neighbor-group core.
  B. Apply the BGP_Egress_Filter route policy to the BGP neighbor-group packet core on AG1.
  C. Configure AG1 to allocate a label to the BGP routes that are received in the BGP session group transport.
  D. Configure AG1 to allow the 300:100 and 200:100 communities in the BGP_Egress_Filter route policy.
  B. Apply the BGP_Egress_Filter route policy to the BGP neighbor-group packet core on AG1.

• Question 95:

  Refer to the exhibit.

  

  BGP is running in the core of the service provider to exchange routes for its customers, and OSPF serves as the PE-CE routing protocol. The service provider's existing customer at CE1 is opening a new office in a different geographical location connected via CE2. A network engineer must update the BGP implementation so that PE1 and PE2 will share routes and provide communication between CE1 and CE2.

  Which action must the engineer take?

  A. Configure PE1 and PE2 to mutually redistribute BGP and OSPF in the VRF for the customer
  B. Configure CE1 and CE2 with a pseudowire that will run over the service provider core
  C. Configure PE1 and PE2 to redistribute OSPF from the VRF for the customer into BGP
  D. Configure CE1 and CE2 to establish a BGP relationship with PE1 and PE2
  A. Configure PE1 and PE2 to mutually redistribute BGP and OSPF in the VRF for the customer

  ---

  Explanation

  In this scenario, BGP is used in the core of the service provider network, while OSPF serves as the PE-CE routing protocol. To ensure communication between CE1 and CE2, which are located in different geographical locations, it's essential for PE1 and PE2 to share routes. This can be achieved by configuring both PEs to mutually redistribute BGP and OSPF routes within the VRF dedicated for that customer, ensuring seamless communication between both customer endpoints.

• Question 97:

  A network architect dides to expand the scope of the multicast deployment within the company network the network is already using PlM-SM with a static RP that supports a high-bandwidth. video-based training application that s heavily used by the employees, but excessive bandwidth usage is a concern.

  How must the engineer update the network to provide a more efficient multicast implementation'?

  A. Configure IGMP to manage the multicast hosts on each LAN
  B. implement BSR to support dynamic RP notification.
  C. Deploy ICMP to Improve multicast reachability across the network using static RP.
  D. Implement STP to improve switching performance for multicast data.
  B. implement BSR to support dynamic RP notification.

• Question 98:

  An engineer is implementing IGMP with SSM on a multicampus network that supports video streaming. Which task must the engineer perform as part of the process?

  A. Configure an RP that uses static assignments only.
  B. Configure the network to use the PIM bsr-candidate.
  C. Configure the network to use bidirectional PIM.
  D. Configure the network to use IGMPv3.
  D. Configure the network to use IGMPv3.

  ---

  Explanation

  In a multicampus network that supports video streaming, the engineer should configure the network to use IGMPv3 . IGMPv3 is the version of IGMP that supports Source-Specific Multicast (SSM) . SSM allows the receiver to specify the source of the multicast stream, which is particularly useful for video streaming applications. By using SSM, the network can efficiently deliver the video content from the specified source to the receivers without unnecessary traffic from other sources.

• Question 99:

  Refer to the exhibit.

  

  An inter-AS VPN between ISP-A and ISP-B is being deployed to support end-to-end connectivity for CE-1 and CE-2. For scalability reasons, the ASBR routers cannot exchange VPN routes for CE-1 and CE-2.

  Which two configurations are needed to support this requirement? (Choose two.)

  A. one VRF on the ASBRs for each CE
  B. send-labels on the ASBRs
  C. address-family VPNv4 on the ASBRs
  D. ebgp-multihop between the PEs
  E. ebgp-multihop between the ASBRs
  B. send-labels on the ASBRs
  D. ebgp-multihop between the PEs

• Question 100:

  Which statement about TLS is accurate when using RESTCONF to write configurations on network devices'?

  A. It requires certificates for authentication.
  B. It is provided using NGINX acting as a proxy web server
  C. It is used for HTTP and HTTPS requests.
  D. It is not supported on Cisco devices
  A. It requires certificates for authentication.

  ---

  Explanation

  Transport Layer Security (TLS) is essential for securing RESTCONF communications on network devices. TLS provides a secure channel with encryption, ensuring that the data exchanged between the client and server remains private and integral. For RESTCONF to utilize TLS, it requires proper certificates for authentication. These certificates confirm the identity of the devices involved in the communication, preventing man-in-the-middle attacks and unauthorized access.
