  D. Per-flow state is present at the ingress and egress node to the segment routing-enabled network
  E. Per-flow state is maintained on all nodes of the segment routing-enabled network
  B. ECMP-aware traffic engineering is natively supported by segment routing
  C. Per-flow state is present only at the ingress node to the Segment routing-enabled network

• Question 224:

  Refer to the exhibit

  

  Router R1 and its peer R2 reside on the same subnet in the network. If an engineer implements this configuration to R1, how does it make connections to R2?

  A. R1 establishes TCP connections that are authenticated with a clear-text password.
  B. R1 establishes UDP connections that are authenticated with an MD5 password.
  C. R1 establishes UDP connections that are authenticated with a clear-text password.
  D. R1 establishes TCP connections that are authenticated with an MD5 password.
  D. R1 establishes TCP connections that are authenticated with an MD5 password.

  ---

  Explanation

  Router R1 establishes TCP connections that are authenticated with an MD5 password. In the context of BGP (Border Gateway Protocol), TCP is used for establishing connections, and MD5 passwords can be used for authentication to enhance security.

• Question 225:

  Which component is similar to an EVPN instance?

  A. router distinguisher
  B. MPLS label
  C. IGP router ID
  D. VRF
  D. VRF

  ---

  Explanation

  In Cisco Service Provider Network Core Technologies, an EVPN instance can be likened to a VRF (Virtual Routing and Forwarding). A VRF allows multiple instances of a routing table to co-exist within the same router at the same time.

  Similarly, EVPN provides separation between routing instances which aligns with how VRF operates.

• Question 226:

  How is a telemetry session established for data analytics?

  A. A router initiates a session using the dial-out to a destination.
  B. A destination initiate a session to a router.
  C. The destination initiate a session using the dial-out more to the router.
  D. A router requests the data using Teinet.
  A. A router initiates a session using the dial-out to a destination.

  Explanation

• Question 227:

  Refer to the exhibit.

  

  A network engineer is implementing a standard customer route-policy on ASBR1 with these requirements:

  1. It must accept only customer-assigned prefixes 2. It must preserve customer advertised BGP communities 3. It must set the local-preference to 110 for all prefixes 4. It must attach the ORIGINATION-PE and LOCAL-CITY communities to all accepted prefixes.

  Which route policy must the engineer implement on ASBR1 to satisfy the requirements?

  

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

• Question 228:

  While implementing TTL security, an engineer issues the PE(config-router-af)#neighbor 2.2.2.2 ttl-security hops 2 command. After issuing this command, which BGP packets does the PE accept?

  A. from 2.2.2.2, with a TTL of less than 2
  B. to 2.2.2.2, with a TTL of less than 253
  C. from 2.2.2.2, with a TTL of 253 or more
  D. to 2.2.2.2, with a TTL of 2 or more
  C. from 2.2.2.2, with a TTL of 253 or more

  ---

  Explanation

  The ttl-security hops command sets the maximum number of hops that a BGP message can traverse. In this case, setting ttl-security hops 2 means that the router will accept BGP packets from a neighbor (2.2.2.2) only if the TTL is 253 or more. This is because the default TTL value is 255, and for each hop, the TTL is decremented by 1. Therefore, a packet from a directly connected neighbor would have a TTL of 254 when it reaches the PE router. If the packet has traversed one more router (making it two hops away), the TTL would be 253 upon arrival.

  This information is based on the TTL security mechanism described in the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) training materials,

• Question 229:

  Which of the following options is true about Satellite nV System network topologies?

  A. A satellite can be connected to any number of hosts in the hub-and-spoke topology model.
  B. SyncE is only supported on 1 Gigabit Ethernet ICL.
  C. A satellite can be connected to only one host in the hub-and-spoke topology model.
  D. Delete the default SDR after verifying all nodes are in operational state.
  C. A satellite can be connected to only one host in the hub-and-spoke topology model.

• Question 230:

  A network engineer is configuring Flexible NetFlow and enters these commands

  

  What are two results of implementing this feature instead of traditional NetFlow? (Choose two.)

  A. CPU and memory utilization are reduced.
  B. Only the flows of top 100 talkers are exported.
  C. The data export flow is more secure
  D. The number of packets to be analyzed are reduced.
  E. The accuracy of the data to be analyzed is improved.
  A. CPU and memory utilization are reduced.
  D. The number of packets to be analyzed are reduced.

  ---

  Explanation

  Flexible NetFlow improves on traditional NetFlow by providing more flexibility and efficiency in collecting and analyzing network flow data. In this specific configuration, the "mode random one-out-of-100" command is used, which means that only one out of every 100 packets is sampled. This leads to reduced CPU and memory utilization (Option A) because fewer packets are being processed. Additionally, because fewer packets are being analyzed (only one out of every 100), the number of packets to be analyzed is significantly reduced (Option D), leading to further efficiencies.
