Question 3

Which of the following is a purpose of a syslog server?

Accepted Answer

A syslog server collects and aggregates logs from various devices, such as switches, to facilitate easier review and correlation of events.

Question 4

Employees at a company report that they are unable to access the Internet. A network technician notices the workstations are receiving IP addresses that do not follow the IP addressing scheme of the corporate network. Upon further inspection, the technician finds an employee has plugged a rogue wireless router into the corporate network. Which of the following settings would have prevented this situation?

Accepted Answer

DHCP snooping is a security feature that can prevent unauthorized devices from acting as DHCP servers on a network, which would have stopped the rogue router from assigning IP addresses.

Question 5

A network technician needs to replace a failed hard drive on a server at the company's large, remote datacenter. Which of the following types of documentation should be reviewed to locate this server easily?

Accepted Answer

Rack diagrams provide a visual representation of the physical layout of servers and equipment in a datacenter, helping the technician locate the specific server quickly.

Question 6

A network technician is installing a network printer in a factory setting. The connection from the switch contains an LC connector, yet the printer only supports an RJ45 connector. Which of the following should the technician use?

Accepted Answer

A media converter is used to convert the signal from one type of connector to another. In this case, it would convert the LC connector to an RJ45 connector.

Question 7

Which of the following can be used to provide connectivity to a network storage server without the need for dedicated switches and cabling? (Choose two.)

Accepted Answer

FCoE (Fibre Channel over Ethernet) and iSCSI (Internet Small Computer Systems Interface) both allow network storage connectivity over existing Ethernet networks, eliminating the need for dedicated switches and cabling.

Question 8

A company has a DNS record for the following address: products.companyXYZ.com . The company would like to add another record, sales.companyXYZ.com , which continually points to the same IP address as . Which of the following DNS record types would BEST accomplish this?

Accepted Answer

A CNAME (Canonical Name) record is used in DNS to create an alias for another domain name, allowing sales.companyXYZ.com to point to the same IP address as products.companyXYZ.com.

Question 9

A network technician needs to install new network cables. The technician will be running the cables in the air return space above the drop ceiling. Which of the following cable types should be installed?

Accepted Answer

Plenum-rated cables are designed for use in air return spaces because they have a special insulation that is fire-resistant and produces less smoke and toxic fumes in case of a fire.

Question 10

A technician has designed a LAN with redundant switches. Which of the following should be configured to ensure network availability?

Accepted Answer

Spanning Tree Protocol (STP) is used to prevent loops in a network with redundant switches, ensuring network availability by maintaining a loop-free topology.

Question 11

A network technician is helping to install 50 Cat6a drops from users' computers into an IDF. Which of the following is the termination point at the IDF?

Accepted Answer

The answer of A network technician is helping to install...

Question 12

The lack of which of the following components might make a virtual router less efficient than a physical router?

Accepted Answer

ASICs (Application-Specific Integrated Circuits) are specialized hardware used in physical routers to perform packet forwarding and other tasks efficiently. Virtual routers, which run on general-purpose CPUs, may lack this hardware acceleration, making them less efficient in handling high-speed data traffic compared to physical routers with ASICs.

Question 13

A network administrator is attempting to limit the installation of malware on company workstations. The administrator wants to remove root access from the user accounts. Which of the following is this an example of?

Accepted Answer

Removing root access from user accounts is an example of role separation, where users are given only the permissions necessary for their role, reducing the risk of unauthorized actions such as installing malware.

Question 14

A network analyzer captures traffic from a host that is sending 802.1q traffic to a Layer 3 switch. Which of the following attacks is occurring?

Accepted Answer

VLAN hopping is an attack where an attacker sends traffic with 802.1q tags to a switch, attempting to access VLANs they shouldn't be able to.

Question 15

An ARP request is broadcasted and sends the following request: "Who is 192.168.1.200? Tell 192.168.1.55" At which of the following layers of the OSI model does this request operate?

Accepted Answer

ARP (Address Resolution Protocol) operates at the Data Link layer (Layer 2) of the OSI model, as it is responsible for mapping IP addresses to MAC addresses.

Question 16

Which of the following would MOST likely contain information about credential reuse?

Accepted Answer

A password policy typically includes guidelines on credential reuse, such as not using the same password across multiple accounts or systems.

Question 17

A host has an IP address of 172.28.57.144 and is on the 172.28.57.128 subnet. Which of the following is a correct subnet mask of the host?

Accepted Answer

The subnet 172.28.57.128 with a subnet mask of 255.255.255.192 allows for IP addresses from 172.28.57.128 to 172.28.57.191, which includes the host IP 172.28.57.144.

Question 18

Which of the following devices acts as a multiport repeater at the physical layer of the OSI model?

Accepted Answer

A hub acts as a multiport repeater at the physical layer, repeating signals to all ports.

Question 19

Which of the following relies on metrics such as total number of connections or CPU/RAM usage to help maintain performance and availability?

Accepted Answer

Load balancing relies on metrics like total number of connections or CPU/RAM usage to distribute workloads efficiently across multiple servers to maintain performance and availability.

Question 20

A user is connected to the guest wireless network for a video conference with colleagues. The user's computer shows a strong wireless signal, and websites seem to load without issue, but the voice and video have periods of choppiness. Which of the following would BEST identify the issue?

Accepted Answer

The issue is likely related to network congestion or bandwidth limitations, which can be identified by verifying if the wireless network's capacity is exceeded.
