Cisco 400-201 Online Questions & Answers

• Question 251:

  A company has a backup T1 link to its corporate head office. To minimize costs, the company will use the T1 link only for email downloads from the corporate email server. The PPP dialer initiates only when the internal server initiates an email connection to the corporate email server. However, the PPP connection does not disconnect after emails are downloaded. What is the cause of this issue?

  A. The dialer-map command is not configured.
  B. The interface is not added in the dialer-group command.
  C. The dialer-list command is incorrectly configured.
  D. The dialer time-out command is not configured.
  C. The dialer-list command is incorrectly configured.

• Question 252:

  An MPLS TE tunnel is configured with these affinity values:

  affinity= 0x1 mask= 0x3 Which two attribute-flag values applied on the physical interface does this MPLS TE tunnel consider to build the path? (Choose two.)

  A. attribute-flag = 0x1
  B. attribute-flag = 0x3
  C. attribute-flag =0x7
  D. attribute-flag = 0x5
  E. attribute-flag = 0x15
  A. attribute-flag = 0x1
  D. attribute-flag = 0x5

• Question 253:

  Which statement about PIM sparse mode operations is true?

  A. It does not support all underlying unicast routing protocols like BGP
  B. Receivers are registered with RP by their first hop router
  C. From the RP, traffic flows down a source tree to each receiver.
  D. It supports shared trees only, and assumes all hosts want the multicast traffic
  E. Receivers are joined to the shared tree by their local designated router
  E. Receivers are joined to the shared tree by their local designated router

• Question 254:

  Which two protocols can be used for resilience in a Digital Building Ring topology?

  A. IS-IS
  B. LLDP
  C. REP
  D. CDP
  E. STP
  C. REP
  E. STP

• Question 255:

  Unicast Reverse Path Forwarding (Urpf ) can work in the following modes:

  A. Safe mode
  B. Loose mode
  C. Strict mode
  D. Express mode
  E. Tunnel mode
  B. Loose mode
  C. Strict mode

• Question 256:

  What are two uRPF working modes? (Choose two.)

  A. express mode
  B. safe mode
  C. loose mode
  D. strict mode

• Question 257:

  

  Refer to the exhibit. Which data format is used in this script?

  A. JavaScript
  B. API
  C. XML
  D. YANG
  C. XML

• Question 258:

  Which two statements about Layer 3 MPLS VPN are true? (Choose two.)

  A. The virtual routing and forwarding table is separate from the global routing table that exists on PE routers. Routes are injected into the VRF from the CE-PE routing protocols for that VRF and any MP-BGP announcements that match the defined VRF RTs.
  B. Multiprotocol Border Gateway Protocol is run between PE and CE routers to exchange customer prefixes in a VPNv4 format.
  C. A customer edge router peers at Layer 3 to the provider edge. The PE-CE interface runs either a dynamic routing protocol (eBGP, RIPv2, EIGRP, OSPF) or a static routing protocol (Static, Connected).
  D. VPNv4 address is the combination of the RT and customer IPv4 prefix. These VPNv4 prefixes are passed in MP-BGP.
  A. The virtual routing and forwarding table is separate from the global routing table that exists on PE routers. Routes are injected into the VRF from the CE-PE routing protocols for that VRF and any MP-BGP announcements that match the defined VRF RTs.
  C. A customer edge router peers at Layer 3 to the provider edge. The PE-CE interface runs either a dynamic routing protocol (eBGP, RIPv2, EIGRP, OSPF) or a static routing protocol (Static, Connected).

• Question 259:

  What is the payload capacity of an SDH/STM1 circuit?

  A. 155.52 Mbps
  B. 150.336 Mbps
  C. 153.472 Mbps
  D. 151.424 Mbps
  B. 150.336 Mbps

• Question 260:

  Which are two benefits of using segment routing over RSVP-TE for traffic engineering? (Choose two)

  A. Segment routing traffic engineering tunnels always follow the low-latency path
  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
  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
