Which MPLS TE design consideration is true?

A.

MPLS TE replaces LDP and the dependency of the IGP to identify the best path

B.

MPLS TE provides link and node protection

C.

MPLS TE optimizes the routing of IP traffic, given the constraints imposed by backbone capacity and application requirements

D.

MPLS TE requires Layer 3 VPN full-mesh topology deployment

Refer to the exhibit.

Your company designed a network to allow server VLANs to span all access switches in a data center. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches. Which two features improve STP stability within the network design? (Choose two.)

A.

BPDU guard on access ports

B.

BPDU guard on the aggregation switch downlinks toward access switches

C.

root guard on the aggregation switch downlinks toward access switches

D.

root guard on access ports

E.

edge port on access ports

F.

access switch pairs explicitly determined to be root and backup root bridges

Company XYZ runs OSPF in their network. A design engineer decides to implement hot-potato routing architecture. How can this implementation be achieved?

A.

Enable iBGP and apply prepend to ensure all prefixes will have the same length of the AS path attribute value.

B.

Redistribute the external prefixes onto OSPF and ensure the total metric calculation includes only the ext value and the value is the same in all ASBRs.

C.

Enable OSPF load-balancing over unequal cost path.

D.

Redistribute the external prefixes onto OSPF and ensure that the total metric calculation includes external internal values.

What are two key design principles when using a hierarchical core-distribution-access network model? (Choose two.)

A.

A hierarchical network design model aids fault isolation

B.

The core layer is designed first, followed by the distribution layer and then the access layer

C.

The core layer provides server access in a small campus

D.

A hierarchical network design facilitates changes

E.

The core layer controls access to resources for security

Retef to the exhibit.

An engineer is designing a multiarea OSPF network for a client who also has a large EIGRP domain. EIGRP routes are getting redistributed into OSPF. OSPF area 20 has routers with limited memory and CPU resources. The engineer wants to block routes from EIGRP 111 from propagating into area 20 and allow EIGRP 222 routes to flow in. Which OSPF area type fulfills this design requirement?

A.

area 20 as a stub area

B.

type 5 LSA filtering on the ASBR between EIGRP 111 and area 0

C.

area 20 as a NSSA area

D.

type 3 LSA filtering on the ABR between area 0 and area 20

An engineer must redesign the QoS strategy for Company XYZ The current network is experiencing many dropped packets due to oversubscription of the guaranteed bandwidth allocated by the service provider Company XYZ wants a design with a QoS strategy that controls the traffic flow leaving the Edge router to minimize packet drops Which QoS technique can be recommended as a solution?

A.

LLQ

B.

rate-Limiting

C.

policing

D.

traffic shaping

Which feature is supported by NETCONF but is not supported by SNMP?

A.

Distinguishing between configuration data and operational data

B.

Taking administrative actions

C.

Collecting the status of specific fields

D.

Changing the configuration of specific fields

Which methodology is the leading lifecycle approach to network design and implementation?

A.

PPDIOO

B.

Waterfall model

C.

Spiral model

D.

V model

Company XYZ has two routing domains in their network, EIGRP and OSPF. The company wants to provide full reachability between the two domains by implementing redistribution on a router running both protocols They need to design the redistribution in a way that the OSPF routers will see link costs added to external routes. How must the redistribution strategy be designed for this network?

A.

Redistributed using metric type 2 into OSPF

B.

Redistribute using metric type 1 into EIGRP

C.

Redistribute using metric type 1 into OSPF

D.

Redistribute using metric type 2 into EIGRP

Implementing a network automation architecture usually follows a phased approach that increases automation as the new technology and processes in the preceding phases are integrated and adopted. What provides a model that greatly simplifies the interaction with network devices?

A.

vendor specific configuration

B.

network device migration

C.

abstraction layer

D.

CI/CD framework
