Which two protocols are used to provide server based AAA authentication?
Which two protocols are used to provide server-based AAA authentication? (Choose two.) Explanation: Server-based AAA authentication uses an external TACACS or RADIUS authentication server to maintain a username and password database.
Which component of AAA is used to determine which resources?
authorization component
What are two characteristics of voice traffic choose two?
Voice traffic requires at least 384 kbs of bandwidth. Voice traffic consumes lots of network resources. Voice traffic is unpredictable and inconsistent. Voice traffic latency should not exceed 150 ms.
Which two factors are important when deciding which Interior Gateway Routing Protocol to use choose two?
Which two factors are important when deciding which interior gateway routing protocol to use? (Choose two.) Explanation: There are several factors to consider when selecting a routing protocol to implement. Two of them are scalability and speed of convergence.
What are two of the required steps to configure Pat choose two?
Explanation: The steps that are required to configure PAT are to define a pool of global addresses to be used for overload translation, to configure source translation by using the keywords interface and overload, and to identify the interfaces that are involved in the PAT.
What is the purpose of a routing protocol?
Routing protocols are used to facilitate the exchange of routing information between routers. A routing protocol is a set of processes, algorithms, and messages that are used to exchange routing information and populate the routing table with the routing protocol’s choice of best paths.
What is a result of connecting two or more switches together?
Explanation: When two or more switches are connected together, the size of the broadcast domain is increased and so is the number of collision domains. The number of broadcast domains is increased only when routers are added.
What are two reasons a network administrator would segment a network with a layer 2 switch?
What are two reasons a network administrator would segment a network with a Layer 2 switch? (Choose two.)
- to create fewer collision domains.
- to enhance user bandwidth.
- to create more broadcast domains.
- to eliminate virtual circuits.
- to isolate traffic between segments.
What are two reasons a network administrator might want to create subnets choose two?
Two reasons for creating subnets include reduction of overall network traffic and improvement of network performance. Subnets also allow an administrator to implement subnet-based security policies.
What does the IP address 172.17 4.250 24 represent?
What does the IP address 172.17. 4.250/24 represent? Explanation: The /24 shows that the network address is 172.17.
What are the three characteristics of multicast transmission?
What are three characteristics of multicast transmission? (Choose three.)
- The source address of a multicast transmission is in the range of 224.0.
- A single packet can be sent to a group of hosts.
- Multicast transmission can be used by routers to exchange routing information.
What does 24 mean after an IP address?
2.0/24”, the number “24” refers to how many bits are contained in the network. From this, the number of bits left for address space can be calculated. As all IPv4 networks have 32 bits, and each “section” of the address denoted by the decimal points contains eight bits, “192.0.
Which two of the following are considered reserved IP addresses?
Reserved IP addresses are 10.0. 0.0, 172.16. 0.0 to 172.31. 0.0, and 192.168.
How do I know if my IP is reserved?
You can check it by running ipconfig in a Command Prompt, or heading to System Preferences > Network on a Mac. Find the DHCP reservation setting.
What are the special IP addresses?
By even casual observation, you’ll likely have noticed that there are several IP address ranges that are special, including:
- 10.0. 0.0/8 (10.0. 0.0 – 10.255. 255.255)
- 172.16. 0.0/12 (172.16. 0.0 – 172.31. 255.255)
- 192.168. 0.0/16 (192.168. 0.0 – 192.168. 255.255)
What does reserving an IP do?
When you use DHCP IP reservation, you’re telling your Wi-Fi network to assign the same IP address to a specific device whenever that device connects to your network.
Is it better to use static IP or DHCP?
Since static IP address requires manual configurations, it can create network issues if you use it without a good understanding of TCP/IP. While DHCP is a protocol for automating the task of assigning IP addresses. DHCP does not need any manual configuration to connect to local devices or gain access to the Web.
How do I reserve my IP?
Reserve an IP address
- Click My Dashboards > IP Addresses > DHCP & DNS Management.
- Expand the DHCP servers and click a scope to view the IP address details.
- Select the IP address that you want to reserve, and click Edit.
- Select Reserved from the Status drop-down.
- Check the Send Reservation to DHCP Server box.
Why does my router have 2 IP addresses?
Routers are special because they have two IP addresses. This is the side of the router that faces the home network’s computers and has a private IP address. ASSIGNING IP ADDRESSES TO COMPUTERS DYNAMICALLY. One of the primary jobs of a router is to assign IP addresses to the computers on a home network.
What is IP allocation in WIFI?
A router assigns an IP address for any connecting device. Your device must obtain this address to be able to connect to a router. This message means that it cannot do that, and the user is unable to join a Wi-Fi network. Here are the most frequent reasons for that: Poor Wi-Fi signal.
Is reserved IP the same as static IP?
A static IP address is an IP address that’s manually set on a NIC (Network Interface Card). A DHCP Reservation is a pre-set IP that’s provided by a DHCP Server, and given to a NIC when a NIC calls out to a DHCP server for an IP address.
Do I need a static IP?
Most users don’t need static IP addresses. Static IP addresses normally matter more when external devices or websites need to remember your IP address. One example is VPN or other remote access solutions that trust (whitelists) certain IPs for security purposes.
What is a dynamic IP address?
A dynamic IP address is an IP address that an ISP lets you use temporarily. If a dynamic address is not in use, it can be automatically assigned to a different device. Dynamic IP addresses are assigned using either DHCP or PPPoE.
