Network + Questions Missed Flashcards
A network technician is responsible for the basic security of the network. Management has asked if there is a way to improve the level of access users have to the company file server. Right now, any employee can upload and download files with basic system authentication (username and password). What should he configure to increase security?
multifactor- privides a defense layer that makes it difficult for unauhtorized users to break into a system.
A project lead reviews the statement of work for an upcoming project that is focused on identifying potential weaknesses in the organization’s internal and external network infrastructure. As part of the project, a team of external contractors will attempt to employ various attacks against the organization. The work statement specifically addresses the utilization of an automated tool to probe network resources in an attempt to develop logical diagrams indicating weaknesses in the infrastructure. Based on this scope of work, what type of activity is to be performed?
Penetration testing
A switch technician is tasked to centrally manage the switches and segment the switches by broadcast domains. The corporate network is currently using VLAN 1 for all of its devices and uses a single private IP address range with a 24-bit mask. The supervisor wants VLAN 100 to be the management subnet and all switches to share the VLAN information. What option would be best to use?
Use vlsm on the ip addressrange with VTP and 802.1q on the interswitch conections with native vlan 100
You are currently troubleshooting a network connection error. When you ping the default gateway, you receive no reply. You checked the default gateway, and it is functioning properly, but the gateway cannot connect to any of the workstations on the network. Which of the following layers could be causing this issue?
ping requests occur at layer 3 (network), therefore the problem could exist in 1 (physical) 2(data link) or 3 (network). Since phsyics is the only choice from layers 1-3, it is the correct answer. Also, since the gateway cannot reach any of the other devices on the network, it is most likely a cable (physical) issue between the gateway and the network switch.
A network technician has been asked to make the connections necessary to add video transported via fiber optics to the LAN within a building. There will be one fiber connector for the Tx port and another connector for the Rx port. Which of the following is the MOST common connector used on the switch to connect the media converter?
OBJ-2.1: Straight Tip (ST) fiber connections are the most common ones used in fiber optic connections in LAN networking applications. Therefore this is most likely the correct answer.
A network technician at a warehouse must implement a solution that will allow a company to track shipments as they enter and leave the facility. The warehouse workers must scan and concurrently upload large images of items to a centralized server. Which of the following technologies should they utilize to meet these requirements?
OBJ-1.6: 802.11ac is a very fast high-speed Wi-Fi network capable of 1 Gbps speeds over a 5 GHz spectrum – perfect for uploading large image files quickly. Additionally, the warehouse might want to also utilize RFID to allow for the accurate scanning of items using radio frequency tracking tags.
You are setting up uplink ports for multiple switches to communicate with one another. All of the VLANs should communicate from the designated server switch. Which of the following should be set on the uplink ports if VLAN 1 is not the management VLAN?
OBJ-1.3: The Spanning Tree Protocol (STP) is a network protocol used to eliminate bridge loops in Ethernet LANs. STP prevents network loops and associated network outages by blocking redundant links or paths. The redundant paths can be used to keep the network operational if the primary link fails.
As part of unified communications services, QoS must be implemented to provide support for DSCP and CoS. Which of the following OSI layers does QoS operate within?
OBJ-1.2: DSCP is a layer 3 packet, and it is the most commonly used value for QoS of an IP packet (as it gives lots of flexibility). CoS, on the other hand, is a layer 2 packet. Based on the options given, only Layer 2 is correct.
Your company wants to create highly-available data centers. Which of the following will allow the company to continue maintaining an Internet presence at all sites if the WAN connection at their own site goes down?
OBJ-1.3: If a WAN link goes down, BGP will route data through another WAN link if redundant WAN links are available. Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information between autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol.
You are troubleshooting a SQL server on the network. It has been unable to perform an uncompressed backup of the database because it needs several terabytes of disk space available. Which of the following devices should you install to have the MOST cost-efficient backup solution?
OBJ-3.2: A NAS is a Network Attached Storage device, typically a bunch of cheap hard disks and usually arranged in a RAID consisting of either SAS (serial attached SCSI) or SATA disks just like the ones in most desktops.
