Cisco CCNA, CCNP, And CCENT Practice Questions - Hubs, Repeaters, IPv6, And More!

Let's test your knowledge of hubs, repeaters, Ipv6, and other important Cisco certification exam topics!

CCENT Certification:

Which of the following devices is considered a Layer 1 device?

A. hub

B. repeater

C. router

D. switch

Answers: A, B. Hubs and repeaters are both considered Physical layer devices. Switches are Layer Two devices, and routers run at Layer Three.

CCNA Certification:

Briefly describe how IPv6 utilizes broadcasts.

Answer: It doesn't use 'em. That's pretty brief! :)

CCNP Certification / BSCI Exam:

Briefly describe the types of OSPF routes that can be found on a router serving as a total stub router, but not as an ASBR or ABR.

Answer: The routing table of a total stub router can contain intra-area routes (O) and a default inter-area route using the ABR as the next hop.

A typical total stub routing table:

R4#show ip route ospf

O*IA 0.0.0.0/0 [110/11] via 172.34.34.3, 00:07:26, Ethernet0

CCNP Certification / BCMSN Exam:

Identify the true statements:

A. ISL encapsulates all frames before sending them across the trunk.

B. ISL encapsulates all frames before sending them across the trunk, except those belonging to the native VLAN.

C. IEEE 802.1Q encapsulates all frames before sending them across the trunk.

D. IEEE 802.1Q encapsulates all frames before sending them across the trunk, except those belonging to the native VLAN.

E. None of these statements are true.

Answer: A. The Cisco-proprietary trunking protocol ISL does encapsulate all frames before sending them across the trunk. C and D are false because IEEE 802.1Q does not encapsulate frames at all.

CCNP Certification / ISCW Exam:

You're using Security Device Manager to configure an IPS rule for the first time on a particular router. When you click "Create New IPS Rule", what protocol will you then be prompted to enable?

Answer: The Security Device Event Exchange protocol - SDEE.

CCNP Certification / ONT Exam:

In the command "fair-queue 200 128 50", what does the 200 represent?

A. The number of dynamic conversation queues.

B. The bandwidth assigned to interactive conversations.

C. The number of reservable conversation queues.

D. The number of packets that can be held in a single queue.

Answer: D. In this command, "200" is the number of packets that can be held in a single queue."128" is the number of dynamic conversation queues, and "50" is the number of reservable conversation queues.

Cell Phone Repeaters Works Well With Fixed Structures

The process of installing repeaters is complicated. Therefore, you must have an adequate technical install repeaters a.

Repeaters are in stable structures such as buildings that are used outside the strong signal environment, but weaken the interior of the building by concrete barriers.

Working Group:

When the tower starts the signal receiving antenna outside the building. The signal passes through the path that goes from the repeaterBuilding, after which an amplified signal is then received by the phone's internal antenna.

Internal and external antennas operating at a very low frequency. It works like a signal tower, external antenna receives and acts as speaker and signal transmission. In this process, it loses energy, the conversion of loud noise in a low voice.

Repeater receives the low-intensity sound, converts it to a loud noise and then the transmission of an internal antenna,which acts as microphone and passes it to the cell phones.

One thing to note here is that internal and external antenna should not share signal directly avoiding the repeater. So, both the antennas are always separated. In case if a signal is passed from internal antenna to external antenna or vice versa, repeater oscillates generating RF noise between signals coming from cell phones and tower, thereby indicating the non service area.

We can't use repeater in vehicles as the separation of internal and external signal is quite impossible. This can lead to repeater oscillation.

A high gain low power repeater is appropriate at urban place, where the tower is nearby your building. However, in rural area, you need high gain high power repeater, as both inside and outside signals are weak.

Cell Phone Repeaters work well with fixed structures, as the difference between outside and inside signal antennas are stable and you can install repeaters with fixed amplifying parameters. So, there is no oscillation taking place that avoids any noise disturbance.

Mobile Repeaters

mobile repeater includes an amplifier and external antenna, the antenna requires a voltage and an internal AC or DC. This sometimes internal antenna to the amplifier connected to small high-performance systems.

Cell Phone Repeaters are very popular these days. Most people make use of these devices in their offices and homes of good quality phone for clear signal. If you have something important to talk with your customers and the call drops suddenly, you get angry.

However, there is only one of you, facing the problem as it tackles a lot of people with similar problems. Therefore, if problems of this type, you want to get rid of mobile phone masts can be a good choice for you.

They are readily available with internal and external antennas that can be placed on areas of signal coverage, such as roofs and windows. Therefore, you must first find a suitable location to install repeater.

You can use a mobile phone> Repeater from an electronics store near you. However, if you can not find a good quality booster in local stores, then this booster for online research, as many websites on the net that shows a lot of options, such as repeaters.

Cell Phone Repeater will help improve the quality and clarity of incoming and outgoing calls from your phone, even if you live in the region at short range. This device not only provides signals in the office orThe home but also while roaming around or for a holiday. The superior technology of repeaters can achieve strong returns.

However, if you intend to buy a repeater from a website you should check the website and their reputation by doing a little research on their own can help a bit '.

You can also read the reviews and customer feedback posted on the website for more information. You do not need to spend much money in thisRepeaters, because they are cheap.
