You would like to split your local area network (LAN) into two partitions: one for the accounting department computers and one for deploying images to new computers. Which of the following can you use to meet this requirement?

  • VLAN

  • Virtualization

  • Subnetting

  • VPN

Correct answer: VLAN

A VLAN is a custom network that is created from one or more local area networks. It enables a group of devices available on multiple networks to be combined into one logical network.

Virtualization is used to run virtual machines on a physical server. A subnet is the set of devices connected to a router. A virtual private network (VPN) provides a secure, encrypted channel between two sites or a remote user and the corporate network.

142.

A LAN is a group of computers and devices that share a communications line or wireless link to a server within the same geographical area. What is called a LAN that maps devices on a basis other than geographic location?

  • VLAN

  • WAN

  • SD-WAN

  • WAP

Correct answer: VLAN

A VLAN is a group of network devices (computers, servers, and other resources) that behave as if they are connected to a single network segment, even though they might not be. VLAN groups users who communicate most frequently with each other, regardless of physical location, so they can share resources and bandwidth.

A wide area network (WAN) is a collection of interconnected LANs. Software-defined WAN (SD-WAN) is a networking solution that provides improved resiliency and performance. A wireless access point (WAP) is a router that creates a wireless network.

143.

Your end users need access to vendor systems, cloud systems, and your organization's on-premises systems. What security approach can you use to centralize authentication for all of these access requirements?

  • Identity federation

  • SSO

  • Identity replication

  • IAM

Correct answer: Identity federation

Identity federation is a method of linking a user's identity across multiple separate identity management systems, both inside and outside the organization. It enables single sign-on (SSO), which allows users to move between systems using a single user ID and password while maintaining security.

Identity and access management (IAM) is the practice of managing user authentication and authorization.

Identity replication is a fabricated term.

144.

Your company's e-commerce site has increased traffic due to the holiday season. However, some backend servers are experiencing lower utilization than before the holiday season. Where is a logical place to begin troubleshooting this scenario?

  • Network load balancers

  • Failover clusters

  • Server upgrades

  • NIC teaming

Correct answer: Network load balancers

Network load balancers distribute incoming traffic either to less busy back-end servers or in a round robin fashion. Lower workload is a symptom of the load balancers not distributing the workload equally.

145.

A user is complaining that Windows freezes for several minutes, they get a blue screen on their monitor, and the system reboots randomly. When troubleshooting, what component is the probable cause of these issues?

  • RAM

  • Storage

  • Bus

  • USB

Correct answer: RAM

Memory chips are one of the most essential components of any computer. Issues regarding RAM manifest themselves in the unpredictable ways described in this question.

146.

Multiple different applications on the corporate network make frequent requests to a particular computer on the network. Which of the following types of servers is this computer MOST likely to be?

  • Database server

  • Web server

  • Application server

  • Apache server

Correct answer: Database server

Database servers are used to store and manage data and to provide data access for authorized users. This type of server keeps the data in a location that can be backed up. It also allows users and applications to access the data across the network. The applications querying this server are requesting information from the database.

Application servers and web servers provide a service to users, so they're more likely to receive requests from individuals or a mix of apps and people. Apache server is a particular type of web server.

147.

Many organizations have turned to third party providers for IT troubleshooting and remediation. What metric in the Service-Level Agreement (SLA) defines the expected time for the provider to engage and begin work when a problem is reported?

  • Response time

  • Uptime

  • Turnaround time

  • Availability

Correct answer: Response time

Response time in the context of SLAs refers to how long the third party provider has from the time a service ticket is open to when they begin working on the issue.

148.

The standard UNIX/Linux command for read permissions has the following syntax: Execute (x), 1. What does the number "1" stand for?

  • Internal value

  • Maximum number of executes allowed

  • Minimum number of executes allowed

  • File sector for execute output

Correct answer: Internal value

The number 1 is the value assigned by the operating system. The internal value for the write command is 2, and the internal value for the read command is 4.

149.

What is the name of the firmware that is launched and executed when a server is powered on?

  • BIOS

  • MBR

  • GPT

  • CMOS

Correct answer: BIOS

Basic input/output system (BIOS) is firmware used to perform hardware initialization during the booting process. It is embedded on a server's chip. After it is launched, it manages data flow between the computer's operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse, and printer.

The MBR and GUID Partition Table (GPT) are different initialization options for a disk. The complementary metal oxide semiconductor (CMOS) holds configuration settings for the BIOS.

150.

Which of the following is MOST related to the movement of data between various components within a server?

  • PCI

  • NIC

  • DAS

  • DDR

Correct answer: PCI

A bus is a connection between components or devices inside a server and connected to a server. For example, a bus carries data between a CPU and the system memory via the motherboard. PCI is the original standard for buses and was superseded by PCI-X and PCIe.

A network interface card (NIC) allows a server to be connected to a switch. Direct attached storage (DAS) is data storage located within a server. Double data rate (DDR) reads and writes twice as quickly as single data rate (SDR) memory.

151.

What type of DNS database resource record is used to find SMTP email servers?

  • MX

  • EmX

  • A

  • AAAA

Correct answer: MX

Mail exchanger (MX) records are used for mapping a DNS domain name to the mail server. MX records are used by email applications to locate mail servers for a DNS domain based on the destination email address. The MX record stores the mail server information for a particular domain.

152.

What is the FIRST step in the general troubleshooting methodology?

  • Identify the problem

  • Reproduce the problem

  • Determine the problem scope

  • Verify functionality

Correct answer: Identify the problem

It is important to pinpoint how the system is behaving and how that is different from normal operations. Understanding the symptoms of the problem will assist in narrowing the focus in applying resources to the right part of the system.  

Determining the scope of the problem and reproducing it are parts of the problem identification step. Verifying functionality comes later in the process.

153.

The standard UNIX/Linux command for write permissions has the following syntax: Write (w), 2. What does the number "2" stand for?

  • Internal value

  • Maximum number of writes allowed

  • Minimum number of writes allowed

  • File sector for write output

Correct answer: Internal value

The number 2 is the value assigned by the operating system. The internal value for the read command is 4, and the internal value for the execute command is 1.

154.

Which DHCP scope allows traffic to be sent outside of the local area network?

  • Default gateway

  • Intra-LAN range

  • Inter-LAN gateway

  • Router gateway

Correct answer: Default gateway

A scope is a consecutive range of IP addresses that a DHCP server can draw on to fulfill an IP address request from a DHCP client. The default gateway scope sets the IP addresses of the router interface on the local network to allow traffic to be sent outside the LAN.

155.

What IPv6 transition technology embeds an IPv4 address within the IPv6 address?

  • ISATAP

  • Teredo

  • 6to4

  • 4to6

Correct answer: ISATAP

ISATAP is an interface that hosts can use to pass IPv6 traffic over IPv4 networks. It does this by taking an IPv6 frame and applying headers to the frame with IPv4 network information.

156.

What type of hypervisor has direct access to physical hardware and controls hardware resource access between virtual machines?

  • Type 1

  • Type 2

  • Type 3

  • Type 4

Correct answer: Type 1

A bare-metal hypervisor, also known as a Type 1 hypervisor, is virtualization software that has been installed directly onto the computing hardware. This type of hypervisor controls not only the hardware but also one or more guest operating systems.

Type 2 hypervisors run on top of a host operating system. Type 3 and 4 hypervisors do not exist.

157.

All the following are possible solutions to address slow OS performance issues EXCEPT:

  • Increase the number of processes running concurrently

  • Extend the OS drive capacity

  • Defragment the drive

  • Free up space on the OS drive

Correct answer: Increase the number of processes running concurrently

The operating system is the system software that runs the operations of the hardware device. It is responsible for managing resources so that users can run programs. Slow OS performance happens as a result of either too few or incorrectly configured resources.

158.

What category of transmission technology is the fastest and allows users to plug in a wide variety of devices?

  • Serial

  • Parallel

  • Multiplexed

  • Duplexed

Correct answer: Serial

Serial transmission allows devices to leverage high frequencies, which results in a higher net transfer rate. Serial transmission also does not require extensive line checking and stabilization, which enables the fastest type of transmission. USB stands for universal serial bus.
