45
Q

You have been given the task of configuring a new DNS server and giving it a static IP address. The network uses DHCP which is configured to assign IP addresses in the range 192.168.1.100-192.168.1.150 . The network has a subnet range of 192.168.0-192.168.1.255 with a CIDR notation of 192.168.1.0/24. You assign the new DNS server a static IP of 192.168.1.130 as requested by your supervisor. When testing the new DNS server you are unable to contact it on port 53. Given all of this information, what is most likely the issue?

DNS forwarding needs to be enabled on the switch
Conflicting IP assignments for 192.168.1.130
DHCP and DNS are incompatible
Firewall blocking port 53

A

Conflicting IP assignments for 192.168.1.130

CompTIA exam questions are often written in a way that adds lots of unneeded information to cause confusion. When you come across questions like these you should try to pick out the information relevant to the question and ignore the rest. The important bits of information here are the DHCP range and the static IP given to the DNS server. Because the static IP 192.168.1.130 falls into the range of the DHCP server there is likely an IP conflict. This can occur when two network devices are both claiming/assigned the same IP. When using both DHCP and static IPs you must be sure the static IP is not overlapping with the DHCP configuration.

46
Q

A technician is working on a PC that utilizes a RAID array. The user of the system has reported that random files are becoming corrupted on creation with no pattern to the activity. One drive in the array is likely failing and causing the read/write failures. Which of the following types of RAID is MOST likely in use?

RAID 10
RAID 5
RAID 0
RAID 1

A

RAID 0

RAID 0 uses striping and does not use a mirror or parity disk. This means corrupted data cannot be recovered and that an issue on one disk could cause information on other disks to be unreadable.

47
Q

You are an engineer at a large company running virtual machines on premise. A cluster of identical VMs is running behind a shared load balancer.

Cloning
Shallow Copy
VM Migration Wizard
Secure Copy Protocol (SCP)

A

Cloning

In the context of Virtual Machines the term “cloning” means to copy an entire virtual machine to create a duplicate. This is the VM equivalent of copy+paste and is helpful for scaling or creating new servers using an existing “template” server. Note: Some changes can be expected, such as unique attributes like IP addresses and hostnames but everything else will be identical.

Users at EvilCorp™ are complaining the printer in Building 5 of Area 51 is producing pages that are covered in a black dust. What is MOST LIKELY the issue?

Toner cartridge
Scanner assembly
Dirty print tray
Aliens
Fuser
Laser Array
A

Fuser

Dry toner is melted onto paper by the Fuser. A dusty black powder on a freshly printed piece of paper is likely an issue with the Fuser failing to melt the toner onto the page. Without this step the toner will move around and spread causing the dusty appearance. The fuser may need to be replaced or it’s settings adjusted for the type of paper (e.g. some specialty paper may need a higher temperature - consult the printer’s documentation to see if this is possible).
