Question 3

A service provider has a Resilient Ethernet Protocol ring running as a metro backbone between its locations in one city. A customer wants to connect one site with one box redundant to the Resilient Ethernet Protocol ring at two different service provider locations. How can this be done without producing any Layer 2 loops within the network design? "Pass Any Exam. Any Time." - www.actualtests.com 6 Cisco 352-001 Exam
A) Spanning tree at the service provider side only must be enabled.
B) Spanning tree at the customer side only must be enabled.
C) Flex Links at the service provider side only must be enabled.
D) Flex Links at the customer side only must be enabled.
E) EtherChannel at the service provider side and the customer side must be enabled.

A) LACP system priority and switch MAC address
B) LACP port priority and switch MAC address
C) LACP port priority and port number

Question 14

You are the lead network designer for an enterprise company called ABC, and you are leading design discussions regarding IPv6 implementation into their existing network. A question is raised regarding older Layer 2 switches that exist in the network, and if any changes are required to these Layer 2 switches for successful IPv6 implementation. Which two responses should you give? (Choose two.)
A) IPv6 is transparent on Layer 2 switches, so there is no need to make any changes to the Layer 2 switches.
B) If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ICMPv6 snooping at Layer 2 switches.
C) If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support DHCPv6 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.
E) If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ND snooping at Layer 2 switches.

Accepted Answer

IPv6 is generally transparent to Layer 2 switches, so no changes are needed for basic IPv6 traffic. However, for IPv6 multicast, MLD snooping support is necessary to efficiently handle multicast traffic.

Question 15

In a large enterprise network with multiple data centers and thousands of access devices, OSPF is becoming unstable due to link flapping. The current design has the access devices multihomed to large aggregation routers at each of the data centers. How would you redesign the network to improve stability?
A) Add a layer of regional Layer 3 aggregation devices, but leave the ABR function on the data center aggregation routers.
B) Add a layer of regional Layer 2 aggregation devices, but leave the ABR function on the data center aggregation routers.
C) Add a layer of regional Layer 3 aggregation devices and move the ABR function to the regional aggregation device.
D) Add a layer of regional Layer 2 aggregation devices and move the ABR function to the regional aggregation device.

Accepted Answer

Moving the ABR function to regional Layer 3 aggregation devices helps localize OSPF instability and reduces the impact of link flapping on the entire network.

Question 16

In which two ways is a network design improved by the inclusion of IP Event Dampening? (Choose two.)
A) reduces processing load
B) provides sub-second convergence
C) improves network stability
D) prevents routing loops
E) quickly detects network failures

Accepted Answer

IP Event Dampening reduces the processing load on routers by suppressing unnecessary routing updates and improves network stability by preventing routing loops.

Question 17

A service provider creates a network design that runs MPLS in its WAN backbone using OSPF as the IGP routing protocol. What would be two effects of additionally implementing MPLS-TE? (Choose two.)
A) MPLS-TE is required to reroute traffic within less than 1 second in case of a link failure inside the backbone.
B) MPLS-TE is required to route different MPLS QoS service classes through different paths.
C) MPLS-TE and OSPF cannot be used together inside one MPLS network.
D) MPLS-TE cannot use OSPF for the traffic path calculation.
E) MPLS-TE is required to create backup paths independently from the IGP.

MPLS-TE allows for traffic engineering by routing different MPLS QoS service classes through different paths (B). It also enables the creation of backup paths independently from the IGP, providing more control over traffic flows and redundancy (E).

Question 18

Your network operations team is deploying Access Control Lists (ACLs) across your Internet gateways.

Which one of these addresses would the ACL need for traffic sourced from the inside interface, to match the source address of the traffic?
A) inside local
B) outside local
C) inside global
D) outside global

Accepted Answer

The ACL should match the source address of traffic originating from the internal network, which is the "inside local" address.
