2021 Apr 352-001 practice question
Q81. A planned EBGP network will use OSPF to reach the EBGP peer addresses. Which of these conditions should be avoided in the design that could otherwise cause the peers to flap continuously?
A. An ACL blocks TCP port 179 in one direction.
B. IP addresses used to peer are also being sent via EBGP.
C. The OSPF area used for peering is nonbackbone (not area 0).
D. The routers are peered by using a default route sent by OSPF.
Answer: B
Q82. Refer to the exhibit.
A service provider would like to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP-SW2. In which two of these ways can you design this solution? (Choose two.)
A. Enable Y.1731 Connectivity Fault Management on the SP switches.
B. E-LMI PDUs must be forwarded over VPLS.
C. Cisco Discovery Protocol PDUs must be forwarded over the VPLS.
D. Use upward maintenance endpoints on the SP switches.
E. Enable IEEE 802.1ag Connectivity Fault Management on the SP switches.
Answer: DE
Q83. A customer is using a service provider to provide a WAN backbone for a 30-site network. In establishing the network, the customer must work within these constraints:
The customer has a self-managed MPLS backbone.
The VPLS WAN backbone of the service provider does not support PIM snooping.
Multicast VPN must be used for multicast support inside some VRFs.
What can the customer do so that multicast traffic is NOT flooded to all sites?
A. Configure static GRE tunnels and run the MPLS and multicast VPN inside these GRE tunnels.
B. Use Label Switched Multicast for the multicast transport.
C. Use PIM-SSM as the multicast routing protocol with IETF Rosen Draft multicast VPN.
D. Configure a static mapping between multicast addresses and MAC addresses.
E. Use GET VPN to encrypt the multicast packets inside the WAN.
Answer: A
Q84. A network design includes a long signaling delay in notifying the Layer 3 control plane that an interface has failed. Which two of these actions would reduce that delay? (Choose two.)
A. Enable lower data link layer recovery systems to have an opportunity to restore the interface.
B. Increase the notification of interface flaps.
C. Reduce the time for the network to reconverge.
D. Increase network stability.
Answer: AD
Q85. During a corporate merger, a network designer is asked for a solution that will provide connectivity between the two enterprise networks. The solution must have the ability to support video sessions so that the CEO can message merger activities to the employees. The designer decides to consider multicast as a transport with MSDP to provide redundancy. Which transport feature does the network designer need to apply to the interconnecting firewall to ensure that Source-Active messages between the MSDP peers can be sent in both enterprise networks?
A. unicast over a UDP connection
B. multicast over a UDP connection
C. unicast over a TCP connection
D. multicast over a TCP connection
Answer: C

Q86. You are designing the QoS features for a large enterprise network that includes DMVPN. When would you need to configure QoS preclassify?
A. when you are marking packets with the DSCP bits
B. when you are marking packets with the TOS bits
C. when your service provider requires the DSCP bits be set
D. when the QoS policy cannot be based on DSCP ToS bits
Answer: D
Q87. The Service Provider you work for wants to deploy CoS functionality on the P routers of the MPLS core, to provide a complete CoS solution to all customers that purchase services such as dedicated Internet access, MPLS Layer 3 VPN, and Layer 2 VPN (pseudowire). The design requirements are:
. The network supports four service queues with equal treatment for delay, jitter,
and packet loss.
. Queues are numbered 0–3, where 0 is the default queue.
. Three queues have one treatment, whereas the other queue has either one or two
treatments.
. The Service Provider manages control traffic, whereas the customers manage
business critical and best effort.
Which two statements could you recommend to allow for the appropriate level of bandwidth allocation? (Choose two.)
A. Control plane 10%, Real Time 30%, Business Critical 40%, Best Effort 20%
B. Control plane 80%. Real Time 10%, Business Critical 5%, Best Effort 5%
C. Control plane 90%, Real Time 5%, Business Critical 5%, Best Effort 0%
D. Control plane 20%, Real Time 40%, Business Critical 30%, Best Effort 10%
Answer: AD
Q88. Refer to the exhibit.
A service provider using IS-IS has designed this network with all core links at the Layer 2 control plane. How will they adjust the design to reduce the flooding of update packets?
A. Change the area type of the links to be level-1-2 to allow level-1 updates.
B. Change the network type of the links from broadcast to point-to-point.
C. Use IS-IS mesh groups.
D. Configure SPF timers to be more aggressive so that updates are more quickly cleared from the queue.
Answer: C
Q89. Which two factors can significantly affect the OSPF network convergence time? (Choose two.)
A. the tuning of OSPF LSA timers
B. the number of OSPF routes
C. the diameter of the OSPF network
D. different processor capabilities of devices
Answer: AD
Q90. You are designing a large-scale DMVPN network with more than 500 spokes using EIGRP as the IGP protocol. Which design option eliminates potential tunnel down events on the spoke routers due to the holding time expiration?
A. Increase the hold queue on the tunnel interface of the spoke routers.
B. Increase the hold queue on the physical interface of the spoke routers.
C. Increase the hold queue on the physical interface of the hub router.
D. Increase the hold queue on the tunnel interface of the hub router.
E. Apply QoS for pak_priority class.
Answer: D
