Q5:How must the queue sizes be designed to ensure that an application functions correctly?
A. Each individual device queuing delay in the chain must be less than or equal to the application required delay.
B. The queuing delay on every device in the chain must be exactly the same to the application required delay.
C. The default queue sizes are good for any deployment as it compensates the serialization delay.
D. The sum of the queuing delay of all devices plus serialization delay in the chain must be less than or equal to the application required delay.
Correct Answer: D
Q6:Which implementation plan can be used to accommodate this during the migration phase?
An enterprise plans to evolve from a traditional WAN network to a software-defined WAN network. The existing devices have limited capability when it comes to virtualization. As the migration is carried out, enterprise applications and services must not experience any traffic impact.
A. Deploy controllers, deploy SD-WAN edge routers. In the data center, and migrate branch sites.
B. Migrate data center WAN routers, migrate branch sites, and deploy SD-WAN edge routers.
C. Migrate branch sites, migrate data center WAN routers, and deploy controllers.
D. Deploy SD-WAN edge routers in the data center, deploy controllers, and migrate branch sites
Correct Answer: A
Q7:Which two ways to design this solution are true?
(Choose two)
Refer to the exhibit A service provider has a requirement to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP- SW2.
A. Enable unicast heartbeat messages to be periodically exchanged between MEPs
B. Enable Connectivity Fault Management on the SP switches
C. Use upward maintenance endpoints on the SP switches
D. Forward E-LMI PDUs over VPLS
E. Forward LLD PDUs over the VPLS
Correct Answer: BC
Q8:Which technology can be used to fulfill the requirements while avoiding the creation of routing loops?
Company XYZ wants to deploy OSPF. The design plan requires that two OSPF networks be mutually redistributed at multiple locations and ensure end-to-end connectivity to all of the company\’s networks.
A. Create a virtual link between ASBRs.
B. Change the router ID for both ASBRs.
C. Redistribute routes as external type 2 routes.
D. Use route maps on ASBRs to filter routes with tags so they are not redistributed.
Correct Answer: D
To avoid routing loops you need to tag packets https://www.cisco.com/c/en/us/support/docs/ip/open-shortest-path-first-ospf/4170-ospfprocesses.html

A. Increase the size of the hold queue.
B. Increase the size of the large buffers.
C. Decrease the size of the small buffers.
D. Increase the keepalive timers for each BGP neighbor.
Correct Answer: A

B. It prevents switched traffic from traversing suboptimal paths on the network.
C. It allows small, unmanaged switches to be plugged into ports of access switches without the risk of switch loops.
D. It prevents switch loops caused by unidirectional point-to-point link condition on Rapid PVST + and MST
Correct Answer: D
Q12:Which project methodology meets the requirements and have the least impact on the outcome?
A small organization of 20 employees is looking to deliver a network design service for modernizing customer networks to support advanced solutions.

A. MACsec
B. IP source guard
C. DHCP snooping with DAI
D. IPsec
Correct Answer: B
IP source guard is a security feature that helps prevent IP spoofing attacks by allowing only packets with valid source IP addresses to pass through a network device. It uses a combination of source IP address filtering and DHCP snooping to determine the validity of the source IP address.
