SDWAN networks capitalize the usage of broadband Internet links over traditional MPLS links to offer more cost benefits to enterprise customers. However, due to the insecure nature of the public Internet, it is mandatory to use encryption of traffic between any two SDWAN edge devices installed behind NAT gateways.Which overlay method can provide optimal transport over unreliable underlay networks that are behind NAT gateways?
Answer(s): C
-DTLS (Datagram Transport Layer Security) is a secure transport protocol that can be used to encrypt datagrams. However, it is not as widely deployed as IPsec.-TLS (Transport Layer Security) is a secure transport protocol that can be used to encrypt data between two hosts. However, it is not as well-suited for use over unreliable underlay networks as IPsec.-GRE (Generic Routing Encapsulation) is a tunneling protocol that can be used to encapsulate traffic between two hosts. However, it does not provide any encryption, so it is not suitable for use over insecure underlay networks.-IPsec (Internet Protocol Security) is a secure tunneling protocol that can be used to encapsulate traffic between two hosts. It is well-suited for use over insecure underlay networks, as it provides encryption and authentication.Here are some additional details about IPsec:-IPsec is a mature and widely deployed protocol.-IPsec provides strong encryption and authentication.-IPsec can be used to encapsulate traffic between two hosts or between two networks.-
Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the design should be to monitor and keep track of any performance issues by continuously collecting and analyzing statistical information to monitor, correct, and optimize any reduced responsiveness across the network. Which layer accomplishes this design requirement?
Answer(s): B
-Security management is responsible for protecting the network from unauthorized access, use, disclosure, disruption, modification, or destruction.-Accounting management is responsible for tracking and recording network usage, such as the amount of data that is transmitted and received.-Fault management is responsible for detecting and correcting network faults.-Performance management is responsible for monitoring and optimizing network performance.-Therefore, the layer that accomplishes the design requirement of monitoring and keeping track of any performance issues is performance management.Here are some additional details about performance management:-Performance management typically involves collecting statistical information about network performance, such as throughput, latency, and availability.-This information can be used to identify performance problems, such as bottlenecks and congestion.-Performance management can also be used to optimize network performance, such as by adjusting traffic flows or configuring devices.-
Company XYZ has implemented policy-based routing in their network. Which potential problem must be kept in mind about network reconvergence and PBR?
Policy-based routing (PBR) is a routing technique that allows you to control how traffic is routed based on a set of policies. This can be useful for a variety of purposes, such as load balancing, traffic shaping, and security.However, PBR can also create microloops during reconvergence. A microloop is a situation where traffic is routed in a loop, which can cause performance problems. This can happen if the PBR policies are not configured correctly or if there is a change in the network topology.Therefore, it is important to be aware of the potential for microloops when using PBR. You can minimize the risk of microloops by carefully configuring the PBR policies and by monitoring the network for any changes that could cause a loop.The other options are incorrect.-Option A: PBR does not limit network scalability.-Option C: PBR does not reduce convergence time. In fact, it can increase convergence time because it takes longer for the routers to recalculate the routing tables after a change in the network topology.-Option D: PBR does not create microloops during normal operation. Microloops can only occur during reconvergence.-
SD-WAN can be used to provide secure connectivity to remote offices, branch offices, campus networks, data centers, and the cloud over any type of IP-based underlay transport network. Which two statements describe SD-WAN solutions? (Choose two.)
Answer(s): A,D
-SD-WAN solutions separate the control plane from the data forwarding plane. This allows for greater flexibility and scalability, as well as improved security.-SD-WAN solutions typically include centralized orchestration, control, and zero-touch provisioning. This simplifies network management and reduces operational costs.The other options are not as accurate descriptions of SD-WAN solutions.-SD-WAN solutions do not inherently protect against slow performance. However, they can be configured to optimize performance for different types of traffic.-SD-WAN solutions can use a variety of hardware, including commodity and specialized switching hardware. The specific hardware that is used will depend on the requirements of the specific deployment.-Improved operational efficiencies can result in cost savings. However, the extent of the cost savings will vary depending on the specific deployment.

Company XYZ is in the process of identifying which transport mechanism(s) to use as their WAN technology. Their main two requirements are:-a technology that could offer DPI, SLA, secure tunnels, privacy, QoS, scalability, reliability, and ease of management-a technology that is cost-effectiveWhich WAN technology(ies) should be included in the design of company XYZ?

please help with jn0-649 latest dumps
please i need this dump. thanks
i have to take the aws certified developer - associate dva-c02 in the next few weeks and i wanted to know if the questions on your website are the same as the official exam.
all questions are more important
ques 4 answer should be c ie automatically recover from failure
very very useful page
the exams are giving me an eye opener
3rd so far, need to cover more
aligns with the pecd notes
question 4: b securityadmin is the correct answer. https://docs.snowflake.com/en/user-guide/security-access-control-overview#access-control-framework
kindly please share dumps
it is very useful, thank you
need safe rte dumps
can you upload the cis - cpg dumps
q6 = 1. download odt application 2. create a configuration file (xml) 3. setup.exe /download to download the installation files 4. setup.exe /configure to deploy the application
great material
could you please upload sap c_arsor_2302 questions? it will be very much helpful.
vraag 20c: rsa veilig voor symmtrische cryptografie? antwoord c is toch fout. rsa is voor asymmetrische cryptogafie??
so far good
question 31 has obviously wrong answers. tls and ssl are used to encrypt data at transit, not at rest.
pls provide dump for 1z0-1080-23 planning exams
could you please upload the exam?
please upload this
good material
lets see if this is good stuff...
useful information
intéressant
thank you for making the interactive questions
questions are accurate
i need questions/dumps for this exam.
i need this exam, when will it be uploaded
i need the dumps !
very helpful
good source
