IPv4 is running out of addresses
IPv6 is the successor to IPv
IPv6 has a much larger 128-bit address space
All the above

16. Refer to the exhibit. A network technician is tesঞng connecঞvity in a new network. Based on the test
results shown in the exhibit, which device does the technician have connecঞvity with and which device does the technician not have connecঞvity with?
Connecঞvity: switch 2 and no connecঞvity: PC-C
No connecঞvity: switch 1 and connecঞvity: PC-D
No connecঞvity: switch 2 and connecঞvity: PC-B
Connecঞvity: switch 2 and connecঞvity: PC-C
- Refer to the exhibit. What is an example of this command line?
The packet travelled through three routers reached desঞnaঞon
The connecঞon with the router at the 3rd hop is not reachable
The desঞnaঞon router is unreachable
The connecঞon with the router at the 3rd hop is not reachable but it forwards the packet to the
next router and the packets were successfully reached to desঞnaঞon.
- Refer to the exhibit. What is an example of this command line?
The desঞnaঞon router is unreachable
To verify connecঞons

True
False
- Refer to the exhibit. What is an example of this command line?

To verify connecঞons
Look up the IP address (A record) associated with the given domain name
Check the integrity or validity of a file or configuraঞon
d. Unauthorized access results in loss of data. e. Temperature extremes (too hot or too cold) or humidity extremes (too wet or too dry) f. Internal staff commit to fraud
Hardware threats
Environmental threats
Electrical threats
Maintenance threats
- Match the ICMP Message (៤ពិនƐុ)
a. ICMP Echo Message can be used to test the reachability of a host on an IP network. b. An ICMP DesƟnaƟon Unreachable message can be used to noƟfy the source that a desƟnaƟon or service is unreachable. c. When the Time to Live (TTL) field in a packet is decremented to 0, an ICMPv4 Time Exceeded message will be sent to the source host.
TTL expired in transit Request Ɵme out Reply from 192.x.x.x: bytes=32 Ɵme<1ms TTL=
- Match the desƟnaƟon Unreachable codes for ICMPv4 are as follows. (Not all opƟons are used.)
a. Port unreachable b. Host unreachable c. Protocol unreachable d. Net unreachable e. CommunicaƟon with the desƟnaƟon is administraƟvely prohibited (e.g., firewall)
0 1 2 3
