Question 3 Multiple choice

Which three network management requirements are common practices in network design? (Choose three)

  1. A

    Ensure that all network devices have their clocks synchronized.

  2. B

    Collect SNMP poll information for future regression analysis.

  3. C

    Capture both ingress and egress flow-based packets, while avoiding duplication of flows.

  4. D

    Look at average counters instead of instantaneous counters for inconsistent and bursty KPIs, such as CPU utilization and interface utilization.

  5. E

Show answer and explanation

Correct answers: A, B, D

Question 4 Single choice

Which OSPF design consideration, with regards to simplicity and address preservation, must be considered when connecting two Layer 3 switches directly using 10 GBASE-T cabling and formatting an OSPF neighbor adjacency?

  1. A

    Mesh groups must be included in the design

  2. B

    The OSPF Hello and Dead timers must be tuned to detect failures as quickly as possible

  3. C

    The OSPF network type must be set to point-to-multipoint

  4. D

    An OSPF neighbor adjacency formed over loopback interfaces must be placed in Area 0

  5. E

    The OSPF network type must be set to point-to-point

Show answer and explanation

Correct answer: E

Question 5 Multiple choice

You have been asked to design a wireless network solution that will implement context-aware services on an existing network that was initially deployed for data traffic only.

Which two design principles would you follow to increase the location accuracy with the least possible impact on the current setup? (Choose two.)

  1. A

    Use directional antennas to provide better cell separation.

  2. B

    Add access points along the perimeter of the coverage area.

  3. C

    Install additional APs in monitor mode where the co-channel interference would otherwise be affected.

  4. D

    Increase the AP density to create an average inter-access point distance of less than 40 ft.| 12.2meters

  5. E

    Fine tune the access point's radio configuration to have a higher average transmission power to achieve better coverage.

Show answer and explanation

Correct answers: A, D

Question 6 Single choice

Refer to the exhibit.

This enterprise customer wants to stream one-way video from their head office to eight branch offices using multicast. Their current service provider provides a Layer 3VPN solution and manages the CE routers, but they do not currently multicast.

Which solution quickly allows this multicast traffic to go through while allowing for future scalability?

  1. A

    Enable a GRE tunnel between nodes C1 and C4

  2. B

    Enable a GRE tunnel between nodes CE1 and CE2

  3. C

    Enable a GRE tunnel between nodes C2 and C4

  4. D

    Implement hub and spoke MPLS VPN over DMVPN(also known as 2547oDMVPN) between CE1 and
    CE2

  5. E
