Which design decision is directly influenced by CAPEX drivers?
- A . scalability
- B . stability
- C . complexity
- D . manageability
Setting a specific goal for throughput based on per-second data rates between end hosts does not identify the requirements for specific applications When specifying throughput goals for applications, it is important to understand the throughput requirements for each application.
Which two factors that can constrain application layer throughput? (Choose two.)
- A . protocol parameters, such as frame size and retransmission timers
- B . sent packets or cells at networking devices
- C . the pps or cps rate of networking devices
- D . workstation and server availability
- E . end-to-end throughput rates
Which two actions must merchants do to be compliant with the Payment Card Industry Data Security Standard? (Choose two.)
- A . conduct risk analyses
- B . install firewalls
- C . use antivirus software
- D . establish monitoring policies
- E . establish risk management policies
While reviewing an existing network design, you are discussing the characteristics of different STP versions.
Which protocol minimizes unicast flooding during a Topology Change Notification in a Layer 2 switched network with many VLANs?
- A . PVRSTP
- B . MST
- C . STP
- D . PVSTP+
Hybrid cloud computing allows organizations to like advantage of public and private cloud models.
Which best practice should organizations follow to ensure data security in the private cloud?
- A . Use standard protocols for data transmission over the network.
- B . Encrypt data when it is at rest and in motion
- C . Communicate all data security risks to customers and end users.
- D . Use standard network protocols for data communication between unsecured network connections.
Comparing traditional networks with SDN, where the network is only application aware, what is the advantage of SDN architecture?
- A . has faster network convergence time during catastrophic failures
- B . is resilient to scale with fixed number of network devices
- C . integrates real-time information about networking activity with the applications
- D . simplifies device management by managing each device independently
Which two statements explain the operation of BFD asynchronous mode? (Choose two)
- A . BFD asynchronous mode with echo packets combines the control packets and echo packets into a single packet.
- B . BFD asynchronous mode without echo packets uses control packets, and BFD asynchronous mode with echo packets does not.
- C . BFD asynchronous mode with and without echo packets use control packets.
- D . BFD asynchronous without echo packets has control packets sent back to the originating router, which echoes the control packet to detect failures.
- E . BFD asynchronous mode with echo packets uses separate control packets and echo packets.
Company XYZ was not satisfied with the reconvergence time OSPF is taking. BFD was implemented to try to reduce the reconvergence time, but the network is still experiencing delays when having to reconverge.
Which technology will improve the design?
- A . OSPF fast hellos
- B . BFDecho
- C . Change the protocol to BGP
- D . Change the OSPF hello and dead intervals
Refer to the exhibit.
Company XYZ is a large enterprise network where the WAN traffic utilizes most of the link. The IT team in the company often reports Stuck-In-Active problems. The company is set to acquire another company that will also be running EIGRP and which will connect to the Company XYZ R3 and R4 routers This acquisition could make the issue worse.
Which design solution solves this problem?
- A . Utilize the EIGRP unequal cost load-balancing feature on R5 and R6 to provide an intenm solution
- B . Implement EIGRP Route Flap Dampening
- C . Deploy the EIGRP stub capability on R5 and R6 with the connected and summary options enabled.
- D . Advertise only the default route to R5 and R6. filtering all other routes.
