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?
- A . fault management
- B . accounting management
- C . performance management
- D . security management
Which three components are part of the foundational information security principles of the CIA triad? (Choose three.)
- A . cryptography
- B . confidentiality
- C . C. authorization
- D . identification
- E . integrity
- F . availability
Which two benefits can software defined networks provide to businesses? (Choose two.)
- A . provides additional redundancy
- B . decentralized management
- C . reduced latency
- D . enables innovation
- E . reduction of OpEx/CapEx
- F . meets high traffic demands
You want to mitigate failures that are caused by STP loops that occur before UDLD detects the failure or that are caused by a device that is no longer sending BPDUs.
Which mechanism do you use along with UDLD?
- A . Root guard
- B . BPDU guard
- C . Loop guard
- D . BPDU filtering
In an OSPF network with routers connected together with Ethernet cabling, which topology typically takes the longest to converge?
- A . partial mesh
- B . full mesh
- C . ring
- D . squared
- E . triangulated
An architect receives a business requirement from a CTO that states the RTO and RPO for a new system should be as close as possible to zero.
Which replication method and datacenter technology should be used?
- A . asynchronous replication over dual data centers via DWDM
- B . synchronous replication over geographically dispersed dual data centers via MPLS
- C . synchronous replication over dual data centers via Metro Ethernet
- D . asynchronous replication over geographically dispersed dual data centers via CWDM
Refer to the exhibit.
Traffic was equally balanced between Layer 3 links on core switches SW1 and SW2 before an introduction of the new video server in the network. This video server uses multicast to send video streams to hosts and now one of the links between core switches is over utilized.
Which design solution solves this issue?
- A . Add more links between core switches.
- B . Aggregate links Layer 2 link aggregation.
- C . Apply a more granular load- balancing method on SW1.
- D . Apply a more granular load-balancing method on SW2.
- E . Filter IGMP joins on an over -utilized link.
What are two examples of business goals to be considered when a network design is built? (Choose two.)
- A . standardize resiliency
- B . minimize operational costs
- C . integrate endpoint posture
- D . ensure faster obsolescence
- E . reduce complexity
You have been asked to design a high-density wireless network for a university campus.
Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)
- A . Implement a four-channel design on 2.4 GHz to increase the number of available channels
- B . Choose a high minimum data rate to reduce the duty cycle.
- C . increases the number of SSlDs to load-balance the client traffic.
- D . Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.
- E . Enable 802.11n channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.
Which three items do you recommend for control plane hardening of an infrastructure device? (Choose three.)
- A . redundant AAA servers
- B . Control Plane Policing
- C . warning banners
- D . to enable unused. services
- E . SNMPv3
- F . routing protocol authentication
