Question 1

Company XYZ is designing the network for IPv6 security and they have these design requirements:

A switch or router must deny access to traffic from sources with addresses that are correct, but are

topologically incorrect

Devices must block Neighbor Discovery Protocol resolution for destination addresses that are not found

in the binding table.

Which two IPv4 security features are recommended for this company? (Choose two)

Options :

A : IPv6 DHCP Guard

B : IPv6 Source Guard

C : IPv6 Destination Guard

D : IPv6 Prefix Guard

E : IPv6 RA Guard

Answer: C,D

Question 2

The BGP table contains hundreds of thousands of routes. Which design technique improves the convergence time?

Options :

A : Enable TCP path MTU discovery to every neighbor

B : Use TCP ports higher than 1024 for your BGP sessions

C : Deploy BGP route reflectors instead of full-mesh iBGP

D : Deploy BGP confederations within your backbone

Answer: C

Question 3

Company XYZ is planning to deploy primary and secondary (disaster recovery) data center sites. Each of these sites will have redundant SAN fabrics and data protection is expected between the data center sites. The sites are 100 miles (160 km) apart and target RPO/RTO are 3 hrs and 24 hrs, respectively. Which two considerations must Company XYZ bear in mind when deploying replication in their scenario? (Choose two.)

Options :

A :

Target RPO/RTO requirements cannot be met due to the one-way delay introduced by the distance between sites.

B : VSANs must be routed between sites to isolate fault domains and increase overall availability.

C : Synchronous data replication must be used to meet the business requirements

D :

Asynchronous data replication should be used in this scenario to avoid performance impact in the primary site.

E :

VSANs must be extended from the primary to the secondary site to improve performance and availability.

Answer: B,C

Question 4

Organic growth or decline comes from a company's normal business activities, rather than through acquisitions or divestment. Changes in usage patterns can also cause organic change in network requirements Which tool is useful when designing and operationalizing a network that is in the process of change?

Options :

A : change management

B : modularity

C : mobility

D : monitoring

Answer: A

Question 5

The network designer needs to use GLOP IP address in order make them unique within their ASN, which multicast address range will be considered?

Options :

A : 232.0.0.0 to 232 255.255.255

B : H233.0.0 0 to 233.255.255 255

C : 239000 to 239255255.255
