Cisco 400-007 Online Questions & Answers

• Question 231:

  DRAG DROP

  The network team in XYZ Corp wants to modernize their infrastructure and is evaluating an implementation and migration plan to allow integration MPLS-based, Layer 2 Ethernet services managed by a service provider to connect branches and remote offices. To decrease OpEx and improve response times when network components fail, XYZ Corp decided to acquire and deploy new routers. The network currently is operated over E1 leased lines (2 Mbps) with a managed CE service provided by the telco.

  Drag and drop the implementation steps from the left onto the corresponding targets on the right in the correct order.

• Question 232:

  While reviewing an existing network design, you are discussing the characteristics of different STP versions. Which protocol minimizes unicast flooding during a Topology Change Notification in a Layer 2 switched network with many VLANs?

  A. PVRSTP
  B. MST
  C. STP
  D. PVSTP+
  A. PVRSTP

• Question 233:

  You are leading design discussions about IPv6 implementation into an existing Enterprise network A question is raised regarding older Layer 2 switches that exist in the network, and if any changes are required to these switches for successful IPv6 implementation

  Which two responses do you give? (Choose two.)

  A. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support DHCPv6 snooping at Layer 2 switches
  B. If IPv6 anycast deployment is planned then make sure that Layer 2 switches support NO snooping at Layer 2 switches
  C. IPv6 is transparent on Layer 2 switches so no changes are needed to the Layer 2 switches
  D. If IPv6 multicast deployment is planned, then make sure that Layer 2 switches support MLD snooping at Layer 2 switches
  E. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ICMPv6 snooping at Layer 2 switches
  B. If IPv6 anycast deployment is planned then make sure that Layer 2 switches support NO snooping at Layer 2 switches
  D. If IPv6 multicast deployment is planned, then make sure that Layer 2 switches support MLD snooping at Layer 2 switches

• Question 234:

  Which two characteristics apply to firewall transparent mode operations in a firewall solution design? (Choose two.)

  A. Changes in the existing IP addressing and subnets are required
  B. The firewall can participate actively on spanning tree.
  C. Multicast traffic can traverse the firewall.
  D. OSPF adjacencies can be established through the firewall
  E. The firewall acts like a router hop in the network.
  C. Multicast traffic can traverse the firewall.
  D. OSPF adjacencies can be established through the firewall

• Question 235:

  How can EIGRP topologies be designed to converge as fast as possible in the event of a point-to-point link failure?

  A. Limit the query domain by use of distribute lists.
  B. Build neighbor adjacencies in a triangulated fashion.
  C. Build neighbor adjacencies in squared fashion.
  D. Limit the query domain by use of summarization.
  E. Limit the query domain by use of default routes.
  D. Limit the query domain by use of summarization.

• Question 236:

  Which feature must be part of the network design to wait a predetermined amount of time before notifying the routing protocol of a change in the path in the network?

  A. Transmit delay
  B. Throttle timer
  C. SPF hold time
  D. Interface dampening
  B. Throttle timer

• Question 237:

  Company XYZ must design a strategy to protect their routers from DoS attacks, such as traffic destined to the router's own route processor, using separate control plane categories. Which two capabilities can be used to achieve this requirement? (Choose two.)

  A. Control Plane Protection using queue thresholding on the transit subinterface
  B. Control Plane Protection using port filtering on the transit subinterface
  C. Control Plane Protection using port filtering on the main interface
  D. Control Plane Protection using queue thresholding on the host subinterface
  E. Control Plane Protection using port filtering on the host subinterface
  D. Control Plane Protection using queue thresholding on the host subinterface
  E. Control Plane Protection using port filtering on the host subinterface

• Question 238:

  Which issue poses a challenge for security architects who want end-to-end visibility of their networks?

  A. too many overlapping controls
  B. too many disparate solutions and technology silos
  C. an overabundance of manual processes
  D. a network security skills shortage
  B. too many disparate solutions and technology silos

• Question 239:

  Company XYZ, a global content provider, owns data centers on different continents. Their data center design involves a standard three-layer design with a Layer 3-only core. HSRP is used as the FHRP. They require VLAN extension across access switches in all data centers, and they plan to purchase a Layer 2 interconnection between two of their data centers in Europe.

  In the absence of other business or technical constraints, which termination point is optimal for the Layer 2 interconnection?

  A. at the core layer, to offer the possibility to isolate STP domains
  B. at the aggregation layer because it is the Layer 2 to Layer 3 demarcation point
  C. at the access layer because the STP root bridge does not need to align with the HSRP active node
  D. at the core layer because all external connections must terminate there for security reasons
  B. at the aggregation layer because it is the Layer 2 to Layer 3 demarcation point

• Question 240:

  An architect prepares a network design for a startup company. The design must be able to meet business requirements while the business grows and divests due to rapidly changing markets. What is the highest priority in this design?

  A. The network should be hierarchical
  B. The network should be modular.
  C. The network should be scalable.
  D. The network should have a dedicated core.
  B. The network should be modular.
