The RAID controller on a server failed and was replaced with a different brand.
Which of the following will be needed after the server has been rebuilt and joined to the domain? would have to rebuild a new RAID disk, access and restore the most recent backup to the new RAID disk. solid-state drives (SSDs) in a computer or storage array so they work as a logical unit. In hardware-based

The administrator’s network has OSPF for the internal routing protocol. One port going out to the Internet is congested. The data is going out to the Internet, but queues up before sending.
Which of the following would resolve this issue?

Output:
Fast Ethernet 0 is up, line protocol is up
Int ip address is 10.20.130.5/25
MTU 1500 bytes, BW10000 kbit, DLY 100 usec
Reliability 255/255, Tx load 1/255, Rx load 1/255Encapsulation ospf, loopback not set

Half duplex, 100Mb/s, 100 Base Tx/Fx
Received 1052993 broadcasts
0 input errors

0 output errors, 0 collisions, 0 resets network. By changing to full duplex the throughput would be doubled. either send communication or receive communication, but not both at the same time. In full-duplex communication, both devices can send and receive communication at the same time. This means that the effective throughput is doubled and communication is much more efficient.

A network technician receives the following alert from a network device:
“High utilizations threshold exceeded on gi1/0/24 : current value 9413587.54”
Which of the following is being monitored to trigger the alarm? interfacegi1/0/24, has been exceeded. The message has been triggered on the interface link status.

It has been determined by network operations that there is a severe bottleneck on the company’s mesh topology network. The field technician has chosen to use log management and found that one router is making routing decisions slower than others on the network.
This is an example of which of the following? routers. Such a CPU on a router could become bottleneck for the network traffic. The routing through that device would then slow down.

A technician would like to track the improvement of the network infrastructure after upgrades.
Which of the following should the technician implement to have an accurate comparison? operating capacity for your whole network. High-quality documentation should include a baseline for network performance, because you and your client need to know what “normal” looks like in order to detect problems before they develop into disasters. networked devices, baselines include information about four key components:

After a recent breach, the security technician decides the company needs to analyze and aggregate its security logs.
Which of the following systems should be used? aggregated. security event management (SEM). SIEM technology provides real-time analysis of security alerts generated by network hardware and applications. SIEM is sold as software, appliances or managed services, and are also used to log security data and generate reports for compliance purposes. network, security, servers, databases, applications, providing the ability to consolidate monitored data to help avoid missing crucial events.

Company policies require that all network infrastructure devices send system level information to a centralized server.
Which of the following should be implemented to ensure the network administrator can review device error information from one central location? from a central location.

A company is experiencing accessibility issues reaching services on a cloud-based system.
Which of the following monitoring tools should be used to locate possible outages?

A technician has been given a list of requirements for a LAN in an older building using CAT6 cabling.
Which of the following environmental conditions should be considered when deciding whether or not to use plenum-rated cables? space is also an ideal place to run computer network cabling. However, in the event of fire in the building, the network cables can be very hazardous because when they burn, the cable insulation gives off a poisonous smoke that gets circulated around the building. Furthermore, the burning cables help to spread the fire. covered in fire-retardant plastic jacket to avoid the risk of toxic smoke being circulated around the building.

A technician is helping a SOHO determine where to install the server.
Which of the following should be considered FIRST? network, it is unlikely that it will have a datacenter or even a dedicated server room. Any servers installed in the network will still have the same environmental requirements as servers in a large network. The servers should be in a secure isolated area if required. The servers also need to be kept cool and dry. Therefore, the first consideration in a SOHO office is “Environment limitations”: where the servers and other network hardware will be located.
