質問 3

Company XYZ is migrating their existing network to IPv6 and they must plan for Layer 2 and Layer 3 devices Some of the access layer switches do not support IPv6, however, core and distribution switches fully support unicast and multicast routing. The company wants to minimize cost of the migration. Which migration strategy should be used in the design?

（A）Layer 2 switches will not affect the implementation of IPv6. They can be included in the design in their current state.

（B）The access layer switches must support DHCPv6. Any switches that do not support DHCPv6 must be replaced.

（C）The access layer switches must support IGMP snooping at a minimum. Any switches that do not support IGM snooping must be replaced.

（D）Upgrade the nonsupporting switches Otherwise, it will cause an issue with the migration.

質問 4

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 host subinterface

（B）Control Plane Protection using queue thresholding on the transit subinterface

（C）Control Plane Protection using port filtering on the transit subinterface

（D）Control Plane Protection using port filtering on the main interface

（E）Control Plane Protection using port filtering on the host subinterface

質問 5

What best describes the difference between Automation and Orchestration?

（A）Automation refers to an automatic process for completing multiple tasks with conditions and Orchestration refers to executing tasks in parallel.

（B）Automation refers to scripting languages (Python. Ansible etc.) and Orchestration refers to commercial products that control configuration deployment

（C）Automation describes a hands-off configuration process while Orchestration refers to sets of automation tasks that require the network administrator to coordinate

（D）Automation refers to an automatic process for completing a single task and Orchestration refers to assembling and coordinating a set of tasks and conditions.

What are two advantages of controller-based networks versus traditional networks? (Choose two.)

（A）programmatic APIs that are available per device

（B）more consistent device configuration

（C）the ability to have forwarding tables at each device

（D）the ability to configure the features for the network rather than per device

（E）more flexible configuration per device

質問 7

Company XYZ was not satisfied with the reconvergence time OSPF is taking. BFD was implemented to try to reduce the reconvergence time, but the network is still experiencing delays when having to reconverge. Which technology will improve the design?

（A）OSPF fast hellos

（B）Change the protocol to BGP

（C）Change the OSPF hello and dead intervals

（D）BFD echo

質問 9

Company XYZ has a new network based on IPv6. Some of the subnets that they are planning to use will be confidential and need an addressing scheme that confines them to the local campus network. Which type of IPv6 addresses can be used for these networks in the IPv6 addressing design?

（A）private addresses

（B）link-local addresses

（C）local addresses

（D）unique local addresses

質問 10

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 me aggregation layer because it is the Layer 2 to Layer 3 demarcation point

（B）at the core layer, to otter the possibility to isolate STP domains

（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

質問 11

Refer to the exhibit.

This network is running EIGRP as the routing protocol and the internal networks are being advertised in EIGRP. Based on the link speeds, all traffic between London and Rome is getting propagated via Barcelona and the direct link between London and Rome is not being utilized under normal working circumstances. The EIGRP design should allow for efficiency in the routing table by minimizing the routes being exchanged. The link between London and Rome should be utilized for specific routes. Which two steps accomplish this task? (Choose two.)

（A）Filter the routes on the link between London and Barcelona

（B）Configure route leaking of summary routes on the link between London and Rome

（C）Filter the routes on the link between London and Rome

（D）Configure EIGRP route summarization on all the interfaces to summarize the internal LAN routes

質問 13

A software-defined networking (SDN) controller teams network topology information by using BGP link-state sessions with the route reflectors of an MPLS-enabled network. The controller then uses the topology information to apply on-demand traffic policies to the network through a protocol that is supported from all Layer 3 routers Each policy is represented as a RIB entry in the control plane of the router Which SDN model has been implemented?

（A）SD-WAN

（B）SDN hybrid

（C）SDN traffic engineering

（D）SDN centralized
