• Question 512:

  What is the maximum number of routers that each OSPF area (including the backbone) should contain?

  A. 30
  B. 10
  C. 50
  D. 100
  C. 50

• Question 513:

  Which unique characteristics of the Data Center Aggregation layer must be considered by an Enterprise Campus designer?

  A. Layer 3 routing between the Access and Aggregation layers facilitates the ability to span VLANs across multiple access switches, which is a requirement for many server virtualization and clustering technologies.
  B. "East-west" server-to-server traffic can travel between aggregation modules by way of the core, but backup and replication traffic typically remains within an aggregation module.
  C. Load balancing, firewall services, and other network services are commonly integrated by the use of service modules that are inserted in the aggregation switches.
  D. Virtualization tools allow a cost effective approach for redundancy in the network design by using two or four VDCs from the same physical switch.
  C. Load balancing, firewall services, and other network services are commonly integrated by the use of service modules that are inserted in the aggregation switches.

• Question 514:

  A company has a regulatory requirement that all connections between their sites must be encrypted in a manner that does not require maintenance of permanent tunnels. The remote offices are connected by a private MPLS-based service that requires a dynamically changing key, spoke-to-spoke communications, and reuse of the existing IP header. Which type of transport encryption must be used?

  A. GRE VPN
  B. DMVPN
  C. GETVPN
  D. standard IPsec VPN
  B. DMVPN

• Question 515:

  Which of the following EIGRP configuration recommendation in layer 3-access switch?

  A. Static route...
  B. EIGRP stub...
  B. EIGRP stub...

• Question 516:

  When designing remote access to the Enterprise Campus network for teleworkers and mobile workers, which of the following should the designer consider?

  A. It is recommended to place the VPN termination device in line with the Enterprise Edge firewall, with ingress traffic limited to SSL only
  B. Maintaining access rules, based on the source IP of the client, on an internal firewall drawn from a headend RADIUS server is the most secure deployment
  C. VPN Headend routing using Reverse Route Injection (RRI) with distribution is recommended when the remote user community is small and dedicated DHCP scopes are in place
  D. Clientless SSL VPNs provide more granular access control than SSL VPN clients (thin or thick), including at Layer7
  D. Clientless SSL VPNs provide more granular access control than SSL VPN clients (thin or thick), including at Layer7

• Question 517:

  Two companies merge together but different OSPF Processes (domain), no IP overlapping, they want to exchange routing...(Choose 1)

  A. Static OSPF
  B. Virtual link
  C. Route Summarization
  B. Virtual link

• Question 518:

  Two companies recently merged and want to integrate their networks. Both utilize EIGRP to support their complex enterprise networks. Which action can improve the performance of these two separate EIGRP domains?

  A. Enable route summarization at redistribution points.
  B. Adjust the administrative distance to prefer the best routes to each destination.
  C. Remove EIGRP and utilize OSPF instead.
  D. Utilize EIGRP stub routing between the network boundaries of the companies.
  A. Enable route summarization at redistribution points.

• Question 519:

  Which two key components are related to one firewall per ISP design option for e-commerce? (Choose two.)

  A. It is a common approach to single-homing.
  B. This approach is commonly used in large sites.
  C. Any failure on an edge router results in a loss of session.
  D. It has one NAT to two ISP-assigned blocks.
  E. It is difficult to set up and administer.
  C. Any failure on an edge router results in a loss of session.
  D. It has one NAT to two ISP-assigned blocks.

• Question 520:

  Which statement about NIC teaming configurations is true?

  A. With ALB, all ports use one IP address and multiple MAC addresses.
  B. With AFT, two NICs connect to the different switches.
  C. With SFT, all ports are active.
  D. With AFT, all ports use one IP address and multiple MAC addresses.
  A. With ALB, all ports use one IP address and multiple MAC addresses.

  ---

  Adapter fault tolerance (AFT): With AFT designs, two NICs connect to the same switch. One adapter is active and the other standby, and they use one common IP address and MAC address.

  Switch fault tolerance (SFT): With SFT designs, one port is active and the other standby, and they use one common IP address and MAC address. Adaptive load balancing (ALB): With ALB designs, one port receives and all ports transmit

  using one IP address and multiple MAC addresses.
