Chapter 8 - Network Design and Management

Question 1

Network design

Answer 1

The planning of the implementation of a computer network infrastructure.
• Cabling structure
• Quantity, type and location of network devices (router, switches, servers)
• IP addressing structure

Question 2

Network management (maintenance)

Answer 2

A broad range of functions including activities, methods, procedures and the use of tools to administrate, operate, and reliably maintain computer network systems.

Question 3

Network baselining

Answer 3

The act of measuring and rating the performance of a network in real-time situations.

Question 4

Providing a network baseline requires

Answer 4

testing and reporting of
• the physical connectivity, normal network utilization, peak network utilization, and average throughput of the network usage.

Question 5

Maintaining System Software

Answer 5

• Patches

- A patch is a piece of software designed to update a computer program or its supporting data, to fix or improve it.
- This includes fixing security vulnerabilities and other bugs, with such patches usually called bug fixes, and improving the usability or performance.

• Service Packs
- A service pack (SP) is a Windows update, often combining previously released updates, that helps make Windows more reliable.

• Software upgrades
- Major enhancement of the existing network.

Question 6

Downtime or outage duration

Answer 6

A period of time that a system fails to provide or perform its primary function.

•That is why, scheduling a downtime is an important aspect in network maintenance.

Question 7

Tasks during the maintenance

Answer 7

–Repairing the network hardware
–Fixing the connection
–Enhancing the servers performance
–Upgrading the servers
–Patching the software / Updating the software

Question 8

Full backup

Answer 8

Full backup will always back-up the entire source data. If you don’t delete/exclude sources (only add/modify) it will always grow in size because it backs up everything.

Question 9

Differential Backup

Answer 9

• The process is much quicker than a full backup since it only takes a copy of what was changed.
• The backup copy itself takes far less storage space than when a full copy is created each day.

Question 10

Incremental Backup

Answer 10

The main difference is that the incremental backup takes a copy of items changed or added since the last incremental backup job.

Question 11

Hot Spare

Answer 11

A hot spare or hot standby is used as a failover mechanism to provide reliability in system configurations. The hot spare is active and connected as part of a working system.
