Which of the following server types would benefit MOST from the use of a load balancer?

  1. DNS server
  2. File server
  3. DHCP server
  4. Web server

Answer(s): D

Explanation:

The server type that would benefit most from the use of a load balancer is web server. A web server is a server that hosts web applications or websites and responds to requests from web browsers or clients. A load balancer is a device or software that distributes network traffic across multiple servers based on various criteria, such as availability, capacity, or performance. A load balancer can improve the scalability, reliability, and performance of web servers by balancing the workload and preventing any single server from being overloaded or unavailable.

A company uses a hot-site, disaster-recovery model.
Which of the following types of data replication is required?

  1. Asynchronous
  2. Incremental
  3. Application consistent
  4. Constant

Answer(s): D

Explanation:

The type of data replication that is required for a hot-site disaster recovery model is constant. A hot site is a type of disaster recovery site that has fully operational IT infrastructure and equipment that can take over the primary site's functions immediately in case of a disaster or disruption. A hot site requires constant data replication between the primary site and the hot site to ensure that the data is up-to-date and consistent. Constant data replication means that any changes made to the data at the primary site are immediately copied to the hot site without any delay or lag.



A technician is unable to access a server's package repository internally or externally.
Which of the following are the MOST likely reasons? (Choose two.)

  1. The server has an architecture mismatch
  2. The system time is not synchronized
  3. The technician does not have sufficient privileges
  4. The external firewall is blocking access
  5. The default gateway is incorrect
  6. The local system log file is full

Answer(s): D,E

Explanation:

The most likely reasons why the technician is unable to access a server's package repository internally or externally are that the external firewall is blocking access and that the default gateway is incorrect. A package repository is a source of software packages that can be installed or updated on a server using a package manager tool. A package repository can be accessed over a network using a URL or an IP address. However, if there are any network issues or misconfigurations, the access to the package repository can be blocked or failed. An external firewall is a device or software that controls the incoming and outgoing network traffic based on predefined rules or policies. An external firewall can block access to a package repository if it does not allow traffic on certain ports or protocols that are used by the package manager tool. A default gateway is a device or address that routes network traffic from one network to another network. A default gateway can be incorrect if it does not match the actual device or address that connects the server's network to other networks, such as the internet. An incorrect default gateway can prevent the server from reaching the package repository over other networks.



A server administrator was asked to build a storage array with the highest possible capacity.
Which of the following RAID levels should the administrator choose?

  1. RAID 0
  2. RAID 1
  3. RAID 5
  4. RAID 6

Answer(s): A

Explanation:

The RAID level that provides the highest possible capacity for a storage array is RAID 0. RAID 0 is a type of RAID level that provides performance enhancement by using striping. Striping means dividing data into blocks and distributing them across multiple disks to increase speed and capacity. RAID 0 does not provide any fault tolerance or redundancy, as it does not use any parity or mirroring techniques. RAID 0 uses all of the available disk space for data storage, without losing any space for overhead. Therefore, RAID 0 provides the highest possible capacity for a storage array, but also has the highest risk of data loss.
