CompTIA Network+ Certification Exam 認定 N10-009 試験問題 (Q264-Q269):

質問 # 264
A Chief Executive Officer (CEO) of a company purchases a new phone that will be used while traveling to different countries. The CEO needs to be able to place outgoing calls and receive incoming calls on the phone using a SIM card. Which of the following cellular technologies does the CEO's phone need?

A. SLA
B. GSM
C. WDMA
D. CDMA

正解：B

解説：
GSM (Global System for Mobile communications) is the international standard that uses SIM cards to authenticate and connect phones to the cellular network. GSM allows users to place and receive calls while traveling globally, provided they have a SIM card. CDMA, on the other hand, does not use SIM cards in the same way and is primarily used in the United States.

質問 # 265
A network administrator wants to configure a backup route in case the primary route fails. A dynamic routing protocol is not installed on the router. Which of the following routing features should the administrator choose to accomplish this task?

A. Hop count
B. Neighbor adjacency
C. Administrative distance
D. Link state flooding

正解：C

解説：
Introduction to Administrative Distance
Administrative distance (AD) is a value used by routers to rank routes from different routing protocols. AD represents the trustworthiness of the source of the route. Lower AD values are more preferred. If a router has multiple routes to a destination from different sources, it will choose the route with the lowest AD.
Static Routes and Backup Routes
When a dynamic routing protocol is not used, static routes can be employed. Static routes are manually configured routes. To ensure a backup route, multiple static routes to the same destination can be configured with different AD values.
Configuring Static Routes with Administrative Distance
The primary route is configured with a lower AD value, making it the preferred route. The backup route is configured with a higher AD value. In the event of the primary route failure, the router will then use the backup route.
Example Configuration:
plaintext
Copy code
ip route 192.168.1.0 255.255.255.0 10.0.0.1 1
ip route 192.168.1.0 255.255.255.0 10.0.0.2 10
In the above example, 192.168.1.0/24 is the destination network.
10.0.0.1 is the next-hop IP address for the primary route with an AD of 1.
10.0.0.2 is the next-hop IP address for the backup route with an AD of 10.
Verification:
After configuration, use the show ip route command to verify that the primary route is in use and the backup route is listed as a candidate for use if the primary route fails.
Reference:
CompTIA Network+ guide explains the concept of administrative distance and its use in static routing configuration (see page Ref 9 Basic Configuration Commands).

質問 # 267
A network administrator wants to configure a backup route in case the primary route fails. A dynamic routing protocol is not installed on the router. Which of the following routing features should the administrator choose to accomplish this task?

A. Hop count

D. Link state flooding

正解：C

解説：
* Introduction to Administrative Distance
* Administrative distance (AD) is a value used by routers to rank routes from different routing protocols. AD represents the trustworthiness of the source of the route. Lower AD values are more preferred. If a router has multiple routes to a destination from different sources, it will choose the route with the lowest AD.
* Static Routes and Backup Routes
* When a dynamic routing protocol is not used, static routes can be employed. Static routes are manually configured routes. To ensure a backup route, multiple static routes to the same destination can be configured with different AD values.
* Configuring Static Routes with Administrative Distance

* In the above example, 192.168.1.0/24 is the destination network.
* 10.0.0.1 is the next-hop IP address for the primary route with an AD of 1.
* 10.0.0.2 is the next-hop IP address for the backup route with an AD of 10.
