ACME Mining has four data centers in Santiago, Cape Town, Mumbai, and Beijing. They are full-mesh connected via a 400 Mb/s EVP-LAN. A 1-TB transfer occurs daily via FTP between the Santiago and Mumbai data centers. When testing, the data transfer took an ''unexpected and outrageous, with an average transfer rate of 47 KB/s. The team provided this information.
LAN bandwidth usage below 5% at both data centers during transfer.
WAN bandwidth usage was between 20-30% at both data centers during transfer.
The only QoS on WAN is KB/s strict priority configured for other types of traffic.
There is no QoS on LAN.
The ping RTT average between data centers is 378 milliseconds.
Which action improves the file transfer rate?
You are solving a design failure on a massive Hadoop cluster network that has an application with TCP incast behavior (also known as TCP Throughput collapse) affecting its many-to-one communications with packet loss at the last-hop network device. Which metric must be measured to ensure that the network provides the best performance for this application?

Which feature or technology that affects the operations of IPsec should be taken into account when designing an IPsec network using Authentication header?
As a network designer for a major multiservice network, your first assignment is to improve the IS-IS convergence to meet application requirements. Drag and drop the convergence tools or techniques to be used on your proposal from the left into the corresponding convergence phase on the right.
Which feature must be part of the network design to wait a predetermined amount of time before notifying the routing protocol of a change in the path in the network?
What is an effect of using ingress filtering to prevent spoofed addresses on a network design?
In a network with dynamic mutual redistribution between multiple OSPFv2 and EIGRP boundaries, which two mechanisms avoid suboptimal routing? (Choose two)
What is an implication of using route reflectors in an iBGP topology?
Which three network management requirements are common practices in network design? (Choose three)
You work as a network designer for a company that is replacing their Frame Relay WAN with an MPLS VPN service, where the PE-to-CE routing protocol is BGP. The company has 3000 routes in their distribution routers, and they would like to advertise their access routers through the MPLS network. Their service provider, however, only supports 1000 prefixes per VRF. Which two design solutions can be applied to ensure that your access routers will be able to reach all devices in your network? (Choose two.)
A large enterprise network has two data centers and a WLAN edge with a large hub-and spoke network. The complete network is configured as a single OSPF area, and spoke routers are connected to unreliable WAN links. Which two changes should you make to deploy LSA on the spoke routers? (Choose two)
Which two options are IoT use cases that require the low-latency and high reliability that 5G networks provide? (Choose two)
Which option reduces jitter in a VoIP network?
An operations engineer asks for your help with a new switching deployment. The engineer confirms that STP is enabled on an edge switch, and a particular port is connected to another switch. The switch is not receiving configuration BPDUs, although it appears that everything is functioning correctly in the network. What is the design explanation?
Which three processes are part of the ITILv3 Service Operation? (Choose three)
Which two IoT use cases require the low latency and high reliability that 5G networks provide?

Why is a redundant PIM stub router topology a bad network design decision?
In an Ethernet link containing five routers with OSPF network interface type configured as broadcast, how many OSPF adjacencies are established on this Ethernet link?
Refer to the exhibit.
You are designing a data center migration from one location to another, which requires all existing VLANs spanned to the new data center to maintain host IP addressing. Two temporary Gigabit Ethernet circuits are available to extend the VLANs at Layer 2 to the location as trunk links between core switches in each location. Which solution provides maximum fault isolation between the two data centers to ensure a Layer
Issue in one data center does not affect the other during the migration?
Which OSPF design consideration, with regards to simplicity and address preservation, must be considered when connecting two Layer 3 switches directly using 10 GBASE-T cabling and formatting an OSPF neighbor adjacency?
A BGP route reflector in the network is talking longer than expected to converge during network changes. Troubleshooting has shown that the router cannot handle all the TCP acknowledgements during route updates. Which action can be performed to tune device performance?
Refer to the exhibit.
This enterprise customer wants to stream one-way video from their head office to eight branch offices using multicast. Their current service provider provides a Layer 3VPN solution and manages the CE routers, but they do not currently multicast. Which solution quickly allows this multicast traffic to go through while allowing for future scalability?
