CCNP SWITCH v6: Implementing IP Switching chapter 3 exam
Sep 10th
01. One switch in a Layer 2 switched spanning-tree domain is converted to PVRST+ using the spanning-tree mode rapid-pvst global configuration mode command. The remaining switches are running PVST+. What is the effect on the spanning-tree operation?
- Spanning tree is effectively disabled in the network.
- The PVRST+ switch forwards 802.1D BPDUs, but does not participate as a node in any spanning tree.
- All switches default to one 802.1D spanning tree for all VLANs.
- The PVSRT+ reverts to PVST+ to interoperate with the PVST+ switches. (more…)

CCNA Exploration 4 Accessing the WAN – Chapter 7 exam
Apr 15th
01.Refer to the exhibit. A network technician determines DHCP clients are not working properly. The clients are receiving IP configuration information from a DHCP server configured on the router but cannot access the Internet. From the output in the graphic, what is the most likely problem?
- The DHCP server service is not enabled.
- The inside interface for DCHP is not defined.
- The DHCP pool is not bound to the interface.
- The pool does not have a default router defined for the clients.
- All the host addresses have been excluded from the DHCP pool.
02.Refer to the exhibit. On the basis of the configuration shown, how should the pool of the excluded addresses be assigned to key hosts on the network, such as router interfaces, printers, and servers?
- The addresses are statically assigned by the network administrator.
- The DHCP server dynamically assigns the addresses.
- The addresses must be listed under the DHCP pool of addresses before they are available for static assignment.
- The addresses must be listed under the DHCP pool of addresses before they are available for dynamic assignment. (more…)
DNS Caching at a glance
Apr 14th
What is DNS Caching?! DNS caching is a mechanism that enables a client or a server DNS resolutions queries to be saved locally for a set timeframe on that DNS server or client. A DNS query is a request for name resolution that is sent to a DNS server to resolve a name-to-IP-address.
Since Caching stores the information obtained through a previous query locally it improves DNS performance and substantially reduce DNS related traffic on the network. It eliminates the need for repetitive queries to the remote DNS server.
The period of time or TTL (Time to Live) of which the DNS cached query may be stored in the DNS cache, either on the client side or on the server side, is determined by the authoritative server of that resource record. This value applies to all cached DNS resource records and it will be removed once expired regardless if the same record entry accessed before the TTL expires. (more…)

Manually configuring IP addressing in Windows via Command Prompt
Apr 8th
As a system administrator in any enterprise IT environment the ultimate goal is to insure system uptime and the consistent availability of network resources. Any delay of service, misconfiguration, system downtime, security breach.. etc will have a huge impact on the employees productivity. Time is not calculated by minutes or hours, it is calculated by dollars and how much the company loses within the down time of IT services, and believe me, there is always someone should be blame in these cases, try not to be you.
As for Linux users command line is the fastest and preferred way to configure, modify and fix any problem in no time. Yet in Windows environment most administrators prefer the GUI method to get the job done. However, Windows can be administrated through command line as well; Windows server 2008 Server Core supports strong command line management capabilities. (more…)
