12/9/23, 3:28 PM TestOut LabSim • Question 1: X Incorrect You manage your company's website, which uses a cluster of two servers with a single shared storage device. The shared storage device uses a RAID 1 configuration. Each server has a single connection to the shared storage and a single connection to your ISP . You want to provide redundancy so that a failure on a single component doesn't cause the website to become unavailable. What should you add to your configuration to accomplish this? .. 0 0 () On each server, add a second network connection to connect the server to the shared storage device. Connect one server to the internet through a different ISP. Reconfigure the disk array in a RAID 1 +O configuration. On each server, add a second network connection to the internet. Explanation In this scenario, the ISP is the single point of failure. If the ISP connection goes down, the website will be unavailable. Connecting one server to a different ISP or both servers to two ISPs provides redundancy for the connection. Adding multiple network connections to the shared storage or the same ISP is unnecessary because if the single network connection on one server fails, the other server will still be available. Reconfiguring the storage as a RAID 1 +O allows multiple disk failures, but RAID 1 can sustain a failure on a single disk.

12/9/23, 3:28 PM TestOut LabSim • Question 2: X Incorrect Why should you store backup media off site? .. C To prevent the same disaster from affecting both the network and the backup media () () () To reduce the possibility of theft To comply with government regulations To make the restoration process more efficient Explanation Backup media should be stored off site to prevent the same disaster from affecting the network and the backup media. If your primary facility is destroyed, your only hope of recovery is off site data storage. Off site storage does not significantly reduce the possibility of media theft because it can be stolen while in transit or at your storage location. Off site storage is not a government regulation. Off site storage does not make the restoration process more efficient because additional time is spent retrieving backup media from the offsite storage location.

12/9/23, 3:28 PM TestOut LabSim • Question 3: X Incorrect In addition to performing regular backups, what must you do to protect your system from data loss? () Store the backup media in an on-site fireproof vault. Regularly test restoration procedures. Write-protect all backup media. Restrict restoration privileges to system administrators. Explanation The only way to ensure that you have protection against data loss is to regularly test your restoration procedures. This activity reveals whether or not your backup process functions properly and your restoration and recovery procedures are accurate. It's a good idea to store backup media in a fireproof vault, but it's a better idea to store it off site. You should restrict restoration privileges to trusted staff to prevent confidentiality violations. However, this does not address the issue of data loss protection. Write-protecting backup media provides little real security for the stored data because anyone can flip the switch on the media to remove the protection.

12/9/23, 3:28 PM TestOut LabSim • Question 4: X Incorrect You have purchased a solar backup power device to provide temporary electrical power to critical systems in your data center should the power provided by the electrical utility company go out. The solar panel array captures sunlight, converts it into direct current (DC), and stores it in large batteries. The power supplies on the servers, switches, and routers in your data center require alternating current (AC) to operate. Which electrical device should you implement to convert the DC power stored in the batteries into AC power that can be used in the data center? u Transistor .. 0 Inverter () Capacitor 0 Transformer Explanation A power inverter changes direct current (DC) power to alternating current (AC) power. In this scenario, you can use a power inverter to convert the DC power stored in the batteries to AC power that your servers, switches, and routers can use in an emergency. A transformer is typically used to increase or decrease AC power voltage. A capacitor temporarily stores an electrical charge. Capacitors are used with the chips on a computer memory module that store data. A transistor is used to amplify and switch electrical signals.

U Surge protector () Uninterruptible power supply Explanation A surge protector provides no power loss protection. A UPS, a secondary power source, and a backup power generator all provide reasonable protection from power loss.

12/9/23, 3:28 PM TestOut LabSim • Question 6: X Incorrect You are adding a new rack to your data center, which will house two new blade servers and a new switch. The new servers will be used for virtualization. The only space you have available in the data center is on the opposite side of the room from your existing rack, which already houses several servers, a switch, and a router. You plan to configure a trunk port on each switch and connect them with a straight-through UTP cable that will run across the floor of the data center. To protect equipment from power failures, you also plan to install a UPS on the rack along with redundant power supplies for the server. Will this configuration work? O No, you should not use blade servers for virtualization. 0 0 No, you must implement the UPS and power supplies on the rack externally. Yes, this configuration complies with data center best practices. No, you should not run a cable across the data center floor. No, you must use a cross-over cable to connect the two switches together. Explanation In this scenario, running a cable across the data center floor represents a tripping hazard. It also represents a point of failure, as the cable will be walked on constantly, resulting in it being kicked out of one or both jacks. It will also likely fail prematurely due to the excessive wear. A better option would be to run the cable through the ceiling plenum. Blade servers work well for virtualization as long as they meet the system requirements for the hypervisor software. In the early days of networking, crossover cables were required to uplink two hubs or switches together. However, most modern switches implement auto- MDIX, which detects whether crossover is required and automatically configures the interface for you, making a crossover cable unnecessary. Rack-mounted power supplies and UPS devices are commonly used in data centers.

12/9/23, 3:28 PM TestOut LabSim • Question 7: X Incorrect You are adding a new rack to your data center, which will house two new blade servers and a new switch. The new servers will be used for file storage and a database server. The only space you have available in the data center is on the opposite side of the room from your existing rack, which already houses several servers, a switch, and a router. You plan to configure a trunk port on each switch and connect them with a crossover UTP plenum cable that will run through the suspended tile ceiling in the data center. To provide power for the new devices, you had an electrician install several new 20-amp wall outlets near the new rack. Each device on the rack will be plugged directly into one of these new wall outlets. What is wrong with this configuration? (Select two.) .. You should implement redundant power supplies for the network devices. You should implement a UPS between the wall outlet and the network devices. You must use a straight-through cable to connect the two switches together. You should not run a plenum cable through a suspended tile ceiling. You should not connect networking equipment to a 20-amp wall circuit. Explanation https://labsimapp. testout.com/v6_ 0 _ 577 /exam-engine.html/1ef2cf77-5953-47f0-8c05-96adf43b8e01/exam-session/33064339/78da86ab-0752-47f3-8... 9/13

12/9/23, 3: 28 PM TestOut LabSim In this scenario, all the devices on the new rack will go down if the power from the wall outlet fails for some reason (such as a power outage). To prevent this from happening, you should implement a UPS between the wall outlets and the network devices. In addition, the power supplies used by computing equipment have finite life spans and fail frequently. Because these are mission-critical devices, you should consider implementing redundant power supplies. Plenum network cabling is specifically designed to run through a suspended tile ceiling. The space between the suspended tile and the physical ceiling is called a ceiling plenum. In the early days of networking, crossover cables were required to uplink two hubs or switches together. However, most modern switches implement auto-MDIX, which detects whether crossover is required and automatically configures the interface, allowing you to use either a crossover or straight-through cable. Using a 20-amp circuit for networking equipment is considered a data center best practice. Connecting too many devices to a standard 15-amp wall circuit can overload it and trip its breaker.

12/9/23, 3: 28 PM TestOut LabSim • Question 8: X Incorrect Which of the following devices accepts incoming client requests and distributes those requests to specific servers? l Caching engine (j Media converter .., Load balancer ) CSU/DSU Explanation A load balancer is a device that accepts incoming client requests and distributes those requests to multiple servers. One goal of load balancing is to distribute client requests evenly between multiple servers to improve performance. A CSU/DSU (Channel Service Unit/Data Service Unit) is a device that converts the signal received from the WAN provider into a signal that can be used by equipment at the customer site. An intrusion prevention system (IPS) can detect and respond to security events. A caching engine saves copies of frequently used content, eliminating the need to download the content each time it's requested. A media converter converts signals used on one media type (such as twisted-pair Ethernet) to another media type (such as fiber optic).

12/9/23, 3: 28 PM TestOut LabSim • Question 9: X Incorrect What is the purpose of using Ethernet bonding? (Select two.) Provides increased bus speeds .. Increases read and write operations between the system bus and network adapters Provides a failover solution for network adapters Increases network performance Enables dual remote access (DRA) over a WAN link Explanation For a true fault-tolerant strategy, you must consider all system components. Ethernet bonding (also called adapter teaming) is a fault-tolerant strategy that uses multiple network adapters configured on a failover solution. In the event of a NIC failure, other adapters automatically provide link redundancy. Multiple adapters can also increase performance by distributing the network load between adapters. Ethernet bonding does not provide increased bus speeds, increase read and write operations between the system bus and network adapters, or enable dual remote access (DRA) over a WAN link.

12/9/23, 3: 28 PM TestOut LabSim • Question 1 O: X Incorrect A web server on your network hosts your company's public website. You want to make sure that a NIC failure on the server does not prevent the website from being accessible on the internet. Which solution should you implement? .. c__ Ethernet bonding Q QoS O Spanning Tree () Traffic shaping Explanation Ethernet bonding (also called NIC teaming) logically groups two or more physical connections to the same network. If one NIC fails, the second NIC with a connection to the same network can still be used. Spanning Tree is a protocol on a switch that allows it to maintain multiple paths within a subnet. A traffic shaper (also called a bandwidth shaper) is a device that's capable of modifying the flow of data through a network in response to network traffic conditions. Quality of Service (QoS) refers to a set of mechanisms that try to guarantee timely delivery or minimal delay of important or time-sensitive communications. QoS is particularly important when you implement Voice over IP (VoIP), Video over IP, or online gaming, where delay or data loss make the overall experience unacceptable.
