CCNA Exploration 4 Accessing the WAN – Chapter 4 exam
Mar 13th
01. Which two statements are true regarding network security? (Choose two.)
- Securing a network against internal threats is a lower priority because company employees represent a low security risk.
- Both experienced hackers who are capable of writing their own exploit code and inexperienced individuals who download exploits from the Internet pose a serious threat to network security.
- Assuming a company locates its web server outside the firewall and has adequate backups of the web server, no further security measures are needed to protect the web server because no harm can come from it being hacked.
- Established network operating systems like UNIX and network protocols like TCP/IP can be used with their default settings because they have no inherent security weaknesses.
- Protecting network devices from physical damage caused by water or electricity is a necessary part of the security policy. (more…)

CCNA Exploration 3 LAN Switching and Wireless–Chapter 6 Exam
Sep 24th
01. Refer to the exhibit. Which three statements describe the network design shown in the exhibit? (Choose three.)
- This design will not scale easily.
- The router merges the VLANs into a single broadcast domain.
- This design uses more switch and router ports than are necessary.
- This design exceeds the maximum number of VLANs that can be attached to a switch.
- This design requires the use of the ISL or 802.1q protocol on the links between the switch and the router.
- If the physical interfaces between the switch and router are operational, the devices on the different VLANs can communicate through the router. (more…)
