Question No: 51 – (Topic 2)

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?

  1. Event log

  2. Syslog

  3. SIEM

  4. SNMP

Answer: C Explanation:

Using a Security information and event management (SIEM) product, the security logs can be analyzed andaggregated.

SIEM is a term for software products and services combining security information management (SIM) and 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.

SIEM capabilities include Data aggregation; Log management aggregates data from many sources, including network, security, servers, databases, applications, providing the ability to consolidate monitored data to help avoid missing crucial events.

Question No: 52 – (Topic 2)

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?

  1. Vendor documentation

  2. Recent backups

  3. Physical IP address

  4. Physical network diagram

Answer: B Explanation:

If the RAID controller fails and is replaced with a RAID controller with a different brand the RAID will break. We would have to rebuild a new RAID disk, access and restore the most recent backup to the new RAID disk.

Note: RAID controlleris a hardware device or software program used to manage hard disk drives (HDDs) or solid-state drives (SSDs) in a computer or storage array so they work as a logical unit. In hardware-based RAID, a physical controller is used to manage the RAID array.

Question No: 53 – (Topic 2)

A technician is setting up a new network and wants to create redundant paths through the network. Which of the following should be implemented to prevent performance degradation?

  1. Port mirroring

  2. Spanning tree

  3. ARP inspection

  4. VLAN

Answer: B Explanation:

The Spanning Tree Protocol (STP) is a network protocol that ensures a loop-free topology for any bridged Ethernet local area network. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include spare (redundant) links to provide automatic backup paths if an active link fails, without the danger of bridge loops, or the need for manual enabling/disabling of these backup links.

Question No: 54 – (Topic 2)

A company is experiencing very slow network speeds of 54Mbps. A technician has been hired to perform an assessment on the existing wireless network. The technician has recommended an 802.11n network infrastructure. Which of the following allows 802.11n to reach higher speeds?

  1. MU-MIMO

  2. LWAPP

  3. PoE

  4. MIMO

Answer: D

Explanation:

One way 802.11n achieves superior throughput is through the use of a technology called multiple input, multiple output (MIMO). MIMO uses multiple antennas for transmission andreception.

Question No: 55 – (Topic 2)

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?

  1. TACACS server

  2. Single sign-on

  3. SYSLOG server

  4. Wi-Fi analyzer

Answer: C Explanation:

Syslog is a protocol designed to send log entries generated by a device or process called a facility across an IP network to a message collector, called a syslog server. A syslog

message consists of anerror code and the severity of the error. A syslog server would enable the network administrator to view device error information from a central location.

Question No: 56 – (Topic 2)

It has been determined by network operations that there is a severe bottleneck on the company#39;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?

  1. Network device power issues

  2. Network device CPU issues

  3. Storage area network issues

  4. Delayed responses from RADIUS

Answer: B Explanation:

Network processors (CPUs) are used in the manufacture of many different types of network equipment such as routers. Such a CPU on a router could become bottleneck for the network traffic. The routing through that device would then slow down.

Question No: 57 – (Topic 2)

After a company rolls out software updates, Ann, a lab researcher, is no longer able to use lab equipment connected to her PC. The technician contacts the vendor and determines there is an incompatibility with the latest IO drivers.

  5. Roll back the drivers to the previous version.

Answer: E Explanation:

By rolling back the drivers Ann would be able touse her lab equipment again.

To roll back a driver in Windows means to return the driver to the version that was last installed for the device. Rolling back a driver is an easy way to return a driver to a working version when a driver update fails to fix aproblem or maybe even causes a new problem. Think of rolling back a driver as a quick and easy way to uninstall the latest driver and then reinstall the previous one, all automatically.
