NEW QUESTION # 156
Which of the following disaster recovery concepts is calculated by dividing the total hours of operation by the total number of units?

A. RTO
B. MTTR
C. RPO
D. MTBF

Answer: D

Explanation:
Introduction to Disaster Recovery Concepts:
Disaster recovery involves strategies and measures to ensure business continuity and data recovery in the event of a disaster.
Mean Time Between Failures (MTBF):
MTBF is a reliability metric used to predict the time between failures of a system during operation.
It is calculated by dividing the total operational time by the number of failures.
Formula: MTBF=TotalOperationalTimeNumberofFailures ext{MTBF} = rac{ ext{Total Operational Time}}{ ext{Number of Failures}}MTBF=NumberofFailuresTotalOperationalTime This metric helps in understanding the reliability and expected lifespan of systems and components.

NEW QUESTION # 159
Which of the following most likely determines the size of a rack for installation? (Choose two).

A. Cooling fan speed
B. Switch depth
C. KVM size
D. Server height
E. Hard drive size
F. Outlet amperage

Answer: B,D

Explanation:
Understanding Rack Size Determination:
The size of a rack for installation is determined by the dimensions of the equipment to be housed in it, primarily focusing on the depth and height of the devices.
Switch Depth:
Depth of Equipment: The depth of network switches and other rack-mounted devices directly influences the depth of the rack. If the equipment is deeper, a deeper rack is required to accommodate it.
Industry Standards: Most racks come in standard depths, but it is essential to match the depth of the rack to the deepest piece of equipment to ensure proper fit and airflow.
Server Height:
Height of Equipment: The height of servers and other devices is measured in rack units (U), where 1U equals 1.75 inches. The total height of all equipment determines the overall height requirement of the rack.
Rack Units: A rack's height is typically described in terms of the number of rack units it can accommodate, such as 42U, 48U, etc.

NEW QUESTION # 160
A network administrator is troubleshooting issues with aDHCP serverat a university. More students have recently arrived on campus, and the users areunable to obtain an IP address. Which of the following should the administrator do to address the issue?

A. Change thesubnet mask.
B. Increase thescope size.
C. EnableIP helper.
D. Addaddress exclusions.

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
The issue is thatmore students have arrived on campus, meaningthe available IP addresses are exhausted
. To fix this, the administrator shouldincrease the DHCP scope sizeto allow more devices to obtain IP addresses.
Breakdown of Options:
* A. Enable IP helper- IP helper is used to forward DHCP requests across different subnets. However, the problem here is thatthe DHCP scope is full, not that requests are not reaching the server.
* B. Change the subnet mask- The subnet mask determines the number of available hosts, butchanging it without increasing the IP pool does not help.
* C. Increase the scope size-Correct answer.Expanding the DHCP scope provides more IP addresses for assignment.
* D. Add address exclusions- ExclusionsreserveIP addresses, which would further reduce available addresses instead of solving the issue.
