Cisco Cisco Certifications 352-011 Questions & Answers

• Question 211:

  Which option describes a design benefit of root guard?

  A. It prevents switch loops caused by unidirectional point-to-point link condition on Rapid PVST+ and MST.

  B. It prevents switch loops by detecting on one-way communications on the physical port.

  C. It allows small, unmanaged switches to be plugged into ports of access switches without the risk of switch loops.

  D. It makes the port go immediately into the forwarding state after being connected.

  E. It prevents switched traffic from traversing suboptimal paths on the network.

  F. It does not generate a spanning-tree topology change upon connecting and disconnecting a station on a port.

  Correct Answer: E

• Question 212:

  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

  Correct Answer: D

• Question 213:

  A retail company connects its 250 branches across the globe to the core using MPLS Layer 3 VPN. The company is planning to migrate its traditional telephony services to VoIp, in order to reduce the cost of international calls. What are the two primary concerns when implementing this migration? (Choose two)

  A. Jitter

  B. Call routing design

  C. SRST

  D. MTU

  E. Available bandwidth

  Correct Answer: AE

• Question 214:

  Refer to the exhibit.

  

  You are designing a data center migration from one location to another, which requires all existing VLANs spanned to the new data center to maintain host IP addressing. Two temporary Gigabit Ethernet circuits are available to extend the VLANs at Layer 2 to the location as trunk links between core switches in each location. Which solution provides maximum fault isolation between the two data centers to ensure a Layer Issue in one data center does not affect the other during the migration?

  A. Perform BPDU filtering over the trunk links

  B. Enable STP PortFast on host ports within each data center

  C. Run the dual links as multichassis Etherchannel trunk between core switches within each location

  D. Perform HSRP filtering over the trunk links to maintain active HSRP gateways within each data center for each VLAN

  Correct Answer: A

• Question 215:

  Which are two open-source SDN controllers? (Choose two)

  A. Big Cloud Fabric

  B. OpenContrail

  C. Application Policy Infrastructure Controller

  D. Virtual Application Networks SDN controller

  E. OpenDaylight

  Correct Answer: BE

• Question 216:

  You are solving a design failure on a massive Hadoop cluster network that has an application with TCP incast behavior (also known as TCP Throughput collapse) affecting its many-to-one communications with packet loss at the last-hop network device. Which metric must be measured to ensure that the network provides the best performance for this application?

  A. Availability

  B. Bandwidth utilization

  C. Jitter values

  D. Buffer utilization

  Correct Answer: D

• Question 217:

  Refer to the exhibit.

  

  Company A is running a single-area OSPF, and Company B is running RIP as the IGP with no overlapping IP address spaces. Company A has just acquired Company B and both networks must be merged. Which three design components are recommended to guarantee connectivity and redundancy between the two networks? (Choose three.)

  A. Enable mutual redistribution between OSPF and RIP on one border router.

  B. Enable mutual redistribution between OSPF and RIP on Router A and Router B using route tags.

  C. Increase the administrative distance to 130 for the OSPF external prefixes on Router A and Router B.

  D. Implement an ACL on Router A and Router B to prevent OSPF external routes from being installed in the OSPF database.

  E. Filter external routes on Router A and Router B based on route tags.

  Correct Answer: BCE

• Question 218:

  A network design engineer is designing a new storage area network that combines multiple separate legacy SAN environments within a data center. Which technology isolates events within one of the SAN environment from the others?

  A. FCIP tunnels

  B. N-port ID Virtualization

  C. N-Port Virtualization

  D. Virtual SANs

  Correct Answer: D

• Question 219:

  Which two OSPF network type combinations can you use in the design that requires spoke-to-spoke direct traffic? (Choose two.)

  A. hub as point-to-multipoint and spokes as non-broadcast

  B. hub as point-to-multipoint and spokes as point-to-point

  C. hub as broadcast and spokes as non-broadcast

  D. hub as point-to-point and spokes as point-to-point

  Correct Answer: BC

• Question 220:

  A large ISP is analysing which IGP meets these following requirements

  Network must be resilient against unstable MTU in one side of newly released transmission pieces of equipment

  Network must support MPLS traffic engineering solution for future use

  Which IGP must be selected and why?

  A. ISIS : in case MTU changes your TE tunnels keep the LSP stable

  B. OSPF: adjacency remains up even if MTU changes

  C. OSPF: in case MTU changes your TE tunnels keep the LSP stable

  D. ISIS: adjacency remains up even if MTU changes

  Correct Answer: D
