Cisco Cisco Certifications 352-011 Questions & Answers

• Question 41:

  Which load balancing option for IP-only traffic is the least efficient in terms of EtherChannel physical links utilization?

  A. On a per source IP address basis

  B. On a per destination MAC address basis

  C. On a per destination IP address basis

  D. On a per port number basis

  Correct Answer: B

• Question 42:

  In a design around fast convergence in case of a link failure, what is the justification for using a point-to-point OSPF network type on the Ethernet links between leaf-and-spine switches on a data center fabric?

  A. Link failure tears down neighbor relationships regardless of network type configured

  B. Type 1 LSAs are not generated on a point-to-point network type

  C. Adjacencies can be built faster without a DR/BDR on the segment

  D. The fabric memory requirements are significantly smaller than with a DR/BDR on each leaf and spine segment

  E. The point-to-point network type allows for NSF to be used in this design

  Correct Answer: C

• Question 43:

  A regional ISP is running MPLS TE. These tunnels are configured manually using paths. Which technology centralizes the traffic engineering decisions to reduce operational complexity?

  A. BGP Link State

  B. DiffServ-TE

  C. TE autobandwidth

  D. Shared Risk link Group

  Correct Answer: C

• Question 44:

  Which options do you investigate first when designing fast network convergence?

  A. Routing protocol database size

  B. MTU of the involved interfaces

  C. Link speed between sites

  D. Supported Layer 3 failure detection mechanism

  Correct Answer: D

• Question 45:

  Which reason prevents a designer from using a GDOI-based VPN to secure traffic that traverses the Internet?

  A. Enterprise host IP addresses are typically not routable.

  B. GDOI is less secure than traditional IPsec.

  C. Network address translation functions interfere with tunnel header preservation.

  D. The use of public addresses is not supported with GDOI.

  Correct Answer: C

• Question 46:

  Which four resources does Cisco Cloud Center provision in an ACL environment? (Choose four)

  A. VLAN Pool

  B. Contracts

  C. End point Group (EPG)

  D. VRF

  E. Subject/Filters

  F. Application Network Profile (ANP)

  Correct Answer: BCEF

• Question 47:

  A large enterprise network has a partial mesh network with multiples redundant links. OSPF is used as IGP and it is implemented in a single-area. The network has slow convergence times and there is a high CPU utilization on the routers. Which solution can address these issues while ensuring that the network scales?

  A. Break the routing domain into separate OSPF areas

  B. Make it a hub-and-spoke topology

  C. Replace OSPF with BGP

  D. Reduce the number of links between routers in the network

  E. Upgrade the routers with higher CPU and memory resources

  Correct Answer: A

• Question 48:

  What is design considerations of policy-based routing?

  A. It decreases failure detection time

  B. It can create microloops during network reconvergence

  C. It routes traffic destined to a set of users through different exit points

  D. It uses RSVP to differentiate traffic flows, so queuing mechanisms can prioritize them

  Correct Answer: B

• Question 49:

  Refer to the exhibit.

  

  ACME Mining has four data centers in Santiago, Cape Town, Mumbai, and Beijing. They are full-mesh connected via a 400 Mb/s EVP-LAN. A 1-TB transfer occurs daily via FTP between the Santiago and Mumbai data centers. When testing,

  the data transfer took an ''unexpected and outrageous, with an average transfer rate of 47 KB/s. The team provided this information.

  LAN bandwidth usage below 5% at both data centers during transfer.

  WAN bandwidth usage was between 20-30% at both data centers during transfer.

  The only QoS on WAN is KB/s strict priority configured for other types of traffic.

  There is no QoS on LAN.

  The ping RTT average between data centers is 378 milliseconds.

  Which action improves the file transfer rate?

  A. Use SFTP instead of FTP

  B. Apply optimization techniques at both data centers.

  C. Use TFTP instead of FTP.

  D. Classify FTP transfer and use the strict priority queue on the WAN.

  Correct Answer: B

• Question 50:

  A customer has a DMVPN network with EIGRP as the overlay protocol. EIGRP timers cannot be shortened, yet the customer requires the detection of lost connectivity between neighbors in less than three seconds. Which action achieves this requirement?

  A. Adjust the GRE keepalive timers

  B. Enable BFD

  C. Deploy IPsec dead peer detection

  D. Adjust the NHRP timers.

  Correct Answer: B
