  Refer to the exhibit.

  

  The exhibit shows the topology for an enterprise LAN with an on-site data center.

• Question 63:

  A network architect is planning an update of the server access layer in a data center. Currently, the access layer switches have 10G links to distribution layer switches. In the new solution, HP 5930 Switches act as top of rack (ToR) switches with 40G links to core switches.

  Which factor must the network architect consider when designing solution?

  A. Whether the data center cabling provides enough fiber strands to the racks to support the 40G links
  B. Whether the new switches 40G transceivers are on the chassis front or back, the transceivers must be on the same side as servers air outtakes
  C. Whether the servers connecting to the new switches use Ethernet Virtual Bridging (EVB)/Virtual Ethernet Port Aggregate (VEPA), which is not compatible with 40G
  D. Whether the servers connecting to the new switches have NICs that support Converged Enhanced Ethernet (CEE)
  A. Whether the data center cabling provides enough fiber strands to the racks to support the 40G links

• Question 64:

  Refer to the exhibit.

  

  A network architect is designing the logical topology for a campus LAN networking solution. The customer requires support for 2400 edge ports, which is provided by 10 intelligent Resilient Framework (IRF) groups at the access layer. This customer does not have a wireless network nor anticipants adding one in the next two years. However, the customer does want to authenticate users with 802.1X and use the network RADIUS server to divide users from different groups into different VLANs. The customer has three user groups, each of which includes between 600 and 900 users.

  Additionally, the customer understands that the RADIUS server will require several policies but wants to keep these policies as simple and easy to maintain as possible.

  How can the network architect ensure that the solution meets the customer needs and also follows best practice?

  A. Assign a /23 subnet to each VLAN so that the VLAN can accommodate the required number of users, even if users connect multiple devices
  B. Plan a different VLAN ID and subnet address for each user group on each access layer IRF group. Either core or access layer routing will work for this solution
  C. Use access layer routing. Assign a different subnet to VLAN2 on one access layer IRF group then the VLAN2 on the another access layer group
  D. Plan a solution for designing dissolvable agents to the endpoints so that they can complete 802.1X authentication seamlessly
  B. Plan a different VLAN ID and subnet address for each user group on each access layer IRF group. Either core or access layer routing will work for this solution

• Question 65:

  A network architect is designing a redundancy solution for a customer and has learned that there is a single link between two critical network components. During the past 4000 hours of operation, the link has failed twice. The customer estimates that each failure has taken two hours to resolve.

  Given this information, what is the availability that this link currently provides?

  A. Less than 99.99%
  B. 99.9%
  C. 99.99%
  D. 99.999%
  B. 99.9%

• Question 66:

  

  The customer wants to assign users to VLANs dynamically based on their Windows group. The company Windows Network Policy server provide the assignments. Each of the Windows groups includes between 100 to 600 users. Which issue does the architect need to resolve?

  A. The proposed dynamic VLANs have too many potential users for the proposed subnets.
  B. The plan for the edge ports is incorrect they should be trunk ports that support multiple VLANs.
  C. The switch-to-switch links should not carry so many VLANs.
  D. The proposed switches do not accept dynamic VLAN assignments from Windows NPS servers.
  A. The proposed dynamic VLANs have too many potential users for the proposed subnets.

• Question 67:

  The exhibit shows the topology for a network with 30 access layer switches (only two are shown).Every switch-to-switch link is a Gigabit link. Every area network (VLAN) interface runs. Open Shortest Path First (OSPF) and has the IP address shown in the exhibit. The other interface settings are defaults.

  

  The access layer switches support several more VLANs not shown in the exhibit and also run Multiple Spanning Tree protocol (MSTP) loops. What is one recommendation for enhancing convergence time and resiliency for this solution?

  A. Place all of the switch-to-switch links in the same VLAN.
  B. Lower the cost of the VLAN interfaces to reflect the high speed of the links.
  C. Add a BPDU filter to the VLAN interfaces shown in the exhibit.
  D. Raise the OSPF times on the VLAN interfaces.
  D. Raise the OSPF times on the VLAN interfaces.

• Question 68:

  A network architect is compiling information about the total cost ownership (TCO) for a proposal. Which factors play a role in TCO?

  A. Cost of remediation due to a future security breach
  B. Cost of regulatory fines associated with non-compliance
  C. Cost of upgrading modules for the proposal
  D. Cost of powering the solution
  D. Cost of powering the solution

• Question 69:

  A customer requires high availability, so the network architect is planning two area border (ABRs) for each non-backbone area in the Open Shortest Path First (OSPF) solution. What ensures a loop-free routing environment that meets the customer needs?

  A. All ABRs have at least one interface in area 0, and that interface has an IP address that is outside of the range of any summaries for area 0
  B. Each ABR in an area advertises the same summary routes for the area, and each ABR has a null route that matches those summaries
  C. Only one ABR advertise a summary route for each area. For areas with multiple ABRs, each area can include two summaries ranges, and each ABR is configured with one of those ranges
  D. All ABRs in an area apply consistent path costs for their summary routes
  A. All ABRs have at least one interface in area 0, and that interface has an IP address that is outside of the range of any summaries for area 0

• Question 70:

  

  A company has several branch offers, each of which has four VLANs: one for employees, one for guests, one for network infrastructure local services. At each office, a VLAN has a maximum of 200 endpoints. Each branch office represents one Open Shortest path First (OSP) architect has created the plan shown in the exhibit for IP addressing. What is a potential disadvantage of this design?

  A. The subnets are large enough to accommodate fewer endpoints. But not large enough to accommodate 200 end points
  B. It makes it more complicated for the company to add subnets to branches in the future.
  C. The scheme uses private network addressing space, which is not permitted for use with OSPF.
  D. The address blocks do not provide enough IP addresses for the devices currently at each branch.
  B. It makes it more complicated for the company to add subnets to branches in the future.
