Cisco 352-011 Online Questions & Answers

• Question 151:

  What is a design benefit of PortFast?

  A. PortFast allows small, unmanaged switches to be plugged into ports of access switches without risking switch loops
  B. PortFast disables spanning-tree on the port, which puts the port into the forwarding state immediately after it is connected
  C. Portfast does not generate a spanning-tree topology change when a station on a port is connected or disconnected
  D. PortFast detects one-way communications on the physical port, when prevents switch loops
  E. PortFast prevents switched traffic from traversing suboptimal paths on the network
  F. PortFast prevents switch loops that are caused by a unidirectional point-to-point link condition on Rapid PVST+ and MST
  B. PortFast disables spanning-tree on the port, which puts the port into the forwarding state immediately after it is connected

• Question 152:

  You must measure the amount of traffic that a mobile packet gateway produces when mobile phones access rather than the Internet. Which action do you take to allow this visibility?

  A. Poll OID that is configured for internal servers with SNMP.
  B. Collect information about traffic to the service prowler marked with IP precedence.
  C. Collect traffic information that is related to internal server IP addresses with NetFlow.
  D. Measure traffic characteristics of known internal servers with IP SLA.
  A. Poll OID that is configured for internal servers with SNMP.

• Question 153:

  An operations engineer asks for your help with a new switching deployment. The engineer confirms that STP is enabled on an edge switch, and a particular port is connected to another switch. The switch is not receiving configuration BPDUs, although it appears that everything is functioning correctly in the network. What is the design explanation?

  A. Bridge Assurance is enabled on the port
  B. Storm control broadcast is enabled on the port
  C. REP is enabled on the port
  D. BPDU Guard is enabled on the port
  C. REP is enabled on the port

• Question 154:

  A service provider must provide Internet connectivity to an MPLS Layer 3 VPN customer. Which solution allows this customer to have Internet access?

  A. Implement a global default route with a next hop in the VRF late on PE
  B. Implement policy-based routing between PE and CE
  C. Implement a default route in the VRF with a next hop in the global routing table of PE
  D. Implement destination NAT between the VRF and the global RIB of PE
  C. Implement a default route in the VRF with a next hop in the global routing table of PE

• Question 155:

  Refer to the exhibit.

  

  Service provider ACME Internet just added a 100 GB/s peering in Paris that it wants to use by default for outbound traffic to Big ISP. Which routing policy achieves the desired outcomes?

  A. Use traffic engineering by injecting a preferred LOCAL_PREF attribute to routes advertised from Very Big ISP in Paris
  B. Apply an import policy in New York that adds a Weight attribute to routes learned from Very Big ISP via Paris
  C. Apply an export policy in Paris by applying a MED or community attribute with a preference that very Big ISP act upon
  D. Apply an import policy hat filters longer prefixes than /24 in Brussels and zurich
  A. Use traffic engineering by injecting a preferred LOCAL_PREF attribute to routes advertised from Very Big ISP in Paris

• Question 156:

• Question 157:

  How can jitter be compensated on an IP network that carries real-time VoIP traffic with acceptable voice transmission quality?

  A. Set up VAD to replace gaps on speech with comfort noise
  B. Change CODEC from G.729 to G.711
  C. Deploy RSVP for dynamic VoIP packet classification
  D. Set up a playout buffer to play back the voice stream
  D. Set up a playout buffer to play back the voice stream

• Question 158:

  Your customer asks you to assist with their traffic policy design. They want to guarantee a minimum amount of bandwidth to certain traffic classes. Which technique would you advise them to implement?

  A. Modular QoS CLI
  B. committed access Rate
  C. policy-based routing
  D. traffic shaping
  A. Modular QoS CLI

• Question 159:

  In a routed access hierarchical campus design, the access-to-distribution Layer 2 uplink trunks are replaced with Layer 3 point-to-point routed links. Why is it recommended that VLANs are confined on a single access switch rather than span across multiple access switches?

  A. to allow for better convergence time
  B. to prevent the occurrence of Layer 2 loops
  C. to allow for fault isolation
  D. to prevent routing black holes
  D. to prevent routing black holes

• Question 160:

  Refer to the exhibit.

  

  This Layer 2 ring has 10 VLANs with 1000 MAC addresses in each VLAN. Which protocol or mechanism provides the shortest traffic outage if the link marked with "X" fails?

  A. Ethernet linear protection switching
  B. PVRST
  C. MST
  D. Ethernet ring protection switching
  D. Ethernet ring protection switching
