A network administrator needs to assign IP addresses to a newly installed network. They choose 192.168.1.0/24 as their network address and need to create three subnets with 30 hosts on each subnet. Which of the following is a valid subnet mask that will meet the requirements?
To create three subnets with at least 30 hosts each:
Subnet Calculation: Each subnet must support 32 addresses (30 usable + 2 reserved for network and broadcast).
Bits for Subnets: Subnet mask 255.255.255.192 (/26) provides 64 addresses per subnet (4 subnets total).
Valid Subnets: Each subnet provides sufficient IPs to meet the requirement.
255.255.255.128 (A): Creates only 2 subnets, not enough for the requirement.
255.255.255.224 (C): Provides 8 subnets but only 30 addresses per subnet (28 usable), insufficient for hosts.
255.255.255.240 (D): Too restrictive, only 16 addresses per subnet (14 usable).
A network engineer is completing a new VoIP installation, but the phones cannot find the TFTP server to download the configuration files. Which of the following DHCP features would help the phone reach the TFTP server?
DHCP Options: DHCP options allow additional configuration parameters, such as the address of a TFTP server, to be provided to clients during the DHCP lease process. This is essential for VoIP phones to locate the server for configuration files.
Exclusions (A): Prevents certain IP addresses from being assigned by DHCP but does not direct devices to servers.
Lease time (B): Determines how long an IP address is assigned but does not impact TFTP settings.
Scope (D): Defines a range of IP addresses but does not include additional server information.
An organizatin is struggling to get effective coverage using the wireless network. The organization wants to implement a solution that will allow for continous connectivity anywhere in the facility. Which of the following should the network administ rator suggest to ensure the best coverage?
A client with a 2.4GHz wireless network has stated that the entire office is experiencing intermittent issues with laptops after the WAP was moved. Which of the following is the most likely reason for these issues?
Microwaves are known to interfere with the 2.4GHz frequency, which is the same frequency used by many wireless networks. This can cause signal degradation and intermittent connectivity issues, especially if the WAP is placed near such devices.
SIMULATION
