QUESTION 194
A technician is troubleshooting reports that a networked printer is unavailable. The printer’s IP address is configured with a DHCP reservation, but the address cannot be pinged from the print server in the same subnet. Which of the following is MOST likely the cause of me connectivity failure?

Incorrect VLAN

DNS failure

DHCP scope exhaustion

Incorrect gateway

* A VLAN is a virtual local area network that logically separates devices on the same physical network.
VLANs can improve network performance, security, and management by reducing broadcast domains and isolating traffic.
* A DHCP reservation is a feature that allows a network administrator to assign a specific IP address to a device based on its MAC address. This ensures that the device always receives the same IP address from the DHCP server, even if the lease expires or the device reboots.
* A networked printer is a device that can be shared by multiple users on the same network. A networked printer typically has a built-in network interface card (NIC) that allows it to communicate with other devices using TCP/IP protocols.
* A print server is a device or a software application that manages the printing requests from multiple clients. A print server can also provide additional features such as print queue management, printer driver installation, and printer status monitoring.
* A subnet is a logical division of an IP network that allows devices to communicate more efficiently and securely. A subnet is defined by a network address and a subnet mask, which determine the range of valid IP addresses within the subnet. Devices on the same subnet can communicate directly with each other without the need for a router.
* A ping is a network diagnostic tool that tests the connectivity and reachability between two devices by sending and receiving echo packets. A ping request can fail for various reasons, such as network congestion, firewall settings, routing issues, or device configuration errors.
* Based on the question, the networked printer is unavailable because it cannot be pinged from the print server in the same subnet. This means that there is a problem with the layer 2 connectivity between the two devices, which is determined by the MAC addresses and the VLANs. The most likely cause of this problem is that the printer and the print server are on different VLANs, which prevents them from communicating with each other. The other options are less likely because they affect the layer 3 connectivity, which is determined by the IP addresses and the gateways. A DNS failure would not affect the ping request, since it uses IP addresses and not hostnames. A DHCP scope exhaustion would not affect the printer, since it has a DHCP reservation that guarantees its IP address. An incorrect gateway would not affect the communication within the same subnet, since it is only used for routing packets to other networks. References:

QUESTION 195
Which of the following can be used to decrease latency during periods of high utilization of a firewall?

Hot site

NIC teaming

HA pair

VRRP

QUESTION 196
A technician is trying to install a VolP phone, but the phone is not turning on. The technician checks the cable gong from the phone to the switch, and the cable is good. Which of the following actions IS needed for this phone to work?

Add a POE injector

Enable MDIX.

Use a crossover cable.

Reconfigure the port.

* A POE injector is a device that provides power and data over a single Ethernet cable to a POE device, such as a VoIP phone, a wireless access point, or a security camera12.
* A POE injector is needed when the switch or router that connects to the POE device does not support POE or does not have enough POE ports available12.
* A POE injector can be installed between the switch or router and the POE device, using two Ethernet cables: one from the switch or router to the injector, and another from the injector to the POE device12.
* A POE injector can supply up to 30W of power per port, depending on the POE standard it supports (802.3af or 802.3at)12.
* B. Enable MDIX is not a correct answer because MDIX is a feature that allows a switch or router to automatically detect the type of cable (straight-through or crossover) and adjust the pin assignments accordingly34.
* MDIX is not related to providing power to a POE device, and it is usually enabled by default on modern switches and routers34.
* C. Use a crossover cable is not a correct answer because a crossover cable is a type of Ethernet cable that swaps the transmit and receive pairs of wires, allowing two devices of the same type (such as two switches or two computers) to communicate directly56.
* A crossover cable is not needed to connect a VoIP phone to a switch or router, as they are different types of devices that use different pin assignments56.
* A crossover cable also does not provide power to a POE device, and it may not work with gigabit Ethernet or auto-MDIX devices56.
* D. Reconfigure the port is not a correct answer because reconfiguring the port on the switch or router that connects to the VoIP phone does not address the issue of providing power to the phone78.
* Reconfiguring the port may involve changing the speed, duplex, VLAN, or security settings, but none of these affect the power delivery to the POE device78.
* Reconfiguring the port may also cause network connectivity or performance issues if the settings are not compatible with the VoIP phone or the network78.
