• Question 504:

  Refer to the exhibit.

  

  Router1:

  tacacs-server host 192.168.1.2 single-connection tacacs-server key ciscotest

  What is the result of this configuration?

  A. Router 1 opens and closes a TCP connection to the TACACS+ server every time a user requires authorization.
  B. Router 1 and the TACACS+ server maintain one open connection between them only when network administrator is accessing the router with password ciscotest.
  C. Router 1 and the TACACS+ server maintain one open connection between them.
  D. Router 1 opens and closes a TCP connection to the TACACS+ server every time a user requires authentication.
  C. Router 1 and the TACACS+ server maintain one open connection between them.

  single-connection (Optional) Used to specify a single connection. Rather than have the router open and close a TCP connection to the daemon each time it must communicate, the single-connection option maintains a single open connection between the router and the daemon. This is more efficient because it allows the daemon to handle a higher number of TACACS operations.

• Question 505:

  How do CSC VPN services use BGP to support connectivity between customer sites?

  A. BGP uses address families for IPv6 support in networks that use IPv4 and IPv6 between customers in different geographies.
  B. The BGP AS-Override feature allows the CSC network to use the same autonomous system number.
  C. BGP eliminates the need for an IGP to run within the backbone carrier core and provides more efficient label distribution.
  D. BGP sends labels to the CSC-PE router so that traffic can traverse the backbone carrier.
  D. BGP sends labels to the CSC-PE router so that traffic can traverse the backbone carrier.

• Question 506:

  Refer to the exhibit.

  

  A growing company wants to ensure high availability and redundancy for its critical web servers, which are located in an offsite data center.

  The network architect decided to implement BGP so that the network can use redundant paths for outbound traffic toward the destination subnet 10.2.2.0/24.

  A network engineer already configured basic BGP settings on edge router R1, which is a Cisco ASR-1001X router.

  The engineer also confirmed loopback reachability to routers R2 and R3, and the AS path length toward the destination is the same via R2 and R3.

  Which action must the engineer take on R1 to complete the implementation?

  A. Implement as-path multipath under the BGP neighbor configuration.
  B. Implement maximum-paths ibgp 2 under the BGP neighbor configuration.
  C. Implement maximum-paths 2 under the BGP global configuration.
  D. Implement bestpath as-path multipath-relax under the BGP global configuration.
  D. Implement bestpath as-path multipath-relax under the BGP global configuration.

• Question 507:

  Refer to the exhibit.

  

  Which statement about this configuration is true?

  A. It requires a dynamic Cisco MPLS TE path to be configured for the tunnel to run.
  B. It requires OSPF to also be running to have optimized Cisco MPLS TE tunnels.
  C. It is the configuration for the head-end router of a Cisco MPLS TE tunnel with segment routing.
  D. It requires an explicit Cisco MPLS TE path to be configured for the tunnel to run.
  C. It is the configuration for the head-end router of a Cisco MPLS TE tunnel with segment routing.

• Question 508:

  Refer to the exhibit.

  

  Which statement is true about what this AS filter accomplishes?

  A. It filters incoming BGP update with any AS number starting with the digit 5 and ending with the digit 5,and this only in an AS_PATH.
  B. It filters incoming BGP update with any AS number matching "5.5",but not 515,525.535 etc this only in an AS_SET.
  C. It filters incoming BGP update with any AS number starting with the digit 5 and ending with the digit 5 and this only in an AS_SET.
  D. It allows any number with the statement ".*"and this only in an AS_PATH.
  B. It filters incoming BGP update with any AS number matching "5.5",but not 515,525.535 etc this only in an AS_SET.

• Question 509:

  Refer to the exhibit.

  

  The operations team for a service provider network is implementing a route map policy. OSPF area 0 should originate the default route with a type 2 metric of 2 when the application server on the connected interface (192.168.1.1) is up.

  Routers RL and RM have set up OSPF peering with other adjacent routers. Which action meets this requirement?

  A. Apply default-information originate route-map ospf-default-route on router RL.
  B. Apply default-information originate route-map ospf-default-route on router RM.
  C. Configure distribute-list route-map ospf-default-route out on router RM.
  D. Configure distribute-list route-map ospf-default-route out on router RL.
  A. Apply default-information originate route-map ospf-default-route on router RL.

  ---

  Explanation

  To achieve the origination of a default route based on the condition of the application server being up, a route map policy needs to be applied. This policy should match the condition of the server's status and then use the default-information originate command to originate the default route with the specified metric type and value on router RL.

• Question 510:

  Refer to the exhibit.

  

  Tier 2 ISP A on AS 653 is connected to two Tier 1 ISPs on AS 321 and AS 51 respectively. The network architect at ISP A is planning traffic flow inside the network to provide predictable network services. Cisco Express Forwarding is disabled on the edge router.

  How should the architect implement BGP to direct all traffic via the Tier 1 ISP with next-hop 7.4.5.2?

  A. Implement the BGP routing protocol and run the bgp deterministic-med command.
  B. Implement MP-BGP with a 4-byte AS number with the bgp best path compare-routerid command.
  C. Implement the BGP routing protocol and the maximum-paths 2 configuration.
  D. Implement BGP route-reflector functionality with the bgp always-compare-med configuration.
  A. Implement the BGP routing protocol and run the bgp deterministic-med command.
