A PC connects to two working networks using SOHO routers and different subnets. One of the routers doesn't connect to the Internet, but the other does. You lose access to the Internet when the isolated network is connected. What the likely cause?

A PC connects to two working networks using SOHO routers and different subnets. One of the routers doesn't connect to the Internet, but the other does. You lose access to the Internet when the isolated network is connected. What the likely cause?

• The test network route metric is lower.
• Your Internet goes out at the same time.
• Network issues on the Internet side.
• A system can't be on two separate subnets at once. 

EXPLANATION

 Two subnets on a single VLAN isn't practical.

What does SSHD stand for?

What does SSHD stand for?

• Solid State Hybrid Drive
• Solid State Hard Drive
• Super Speed Hyper Drive
• Solid State Hybrid Disk 

 

EXPLANATION

In computing, a hybrid drive, or SSHD, is a logical or physical storage device that combines a fast storage medium such as NAND flash storage solid-state drive with a hard disk drive, with the intent of adding some of the speed of flash storage to the cost-effective storage capacity of traditional HDDs

What does GUID stand for?

What does GUID stand for?

• Global User Identifier
• Giddy Unicorn In Distress
• Graphical User Interface Denomator
• Globally Unique Identifier 

EXPLANATION

The term globally unique identifier (GUID) is also used, typically in software created by Microsoft.
When generated according to the standard methods, UUIDs are for practical purposes unique, without depending for their uniqueness on a central registration authority or coordination between the parties generating them, unlike most other numbering schemes. While the probability that a UUID will be duplicated is not zero, it is close enough to zero to be negligible.
Thus, anyone can create a UUID and use it to identify something with near certainty that the identifier does not duplicate one that has already been, or will be, created to identify something else. Information labeled with UUIDs by independent parties can therefore be later combined into a single database or transmitted on the same channel, with a negligible probability of duplication.

What is DLL HELL?

What is DLL HELL?

• Down Low Loving Hawt Elastic Lolipop Linux
• Determing Latencey Lag Heap Error or Logic in LDAP
• Dynamic Link Libriary Complications
• DDL Latency - Hybrid ECC Logic Latency 

EXPLANATION

DLL hell is a common term for various problems associated with the use of dynamic link libraries (DLLs) or DLL files. A DLL file is a resource within the Windows operating system that contains code and data related to the functionality of one or more applications.
These files, which may have the file extension .dll or other file extensions, have been a major building block for the Windows operating system and Windows programs since the early MS-DOS versions of Microsoft’s computer technology. Successive versions of Windows have illustrated certain problems with the use of DLL files for many different programs.

What does NTP stand for?

• Network Team Project
• Network Time Protocol
• Netstamp Trouble Process
• Networking Team Process 

EXPLANATION

 Network Time Protocol is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. NTP was designed by David L. Mills of the University of Delaware.

How many bits and bytes are in an IPv4 address?

How many bits and bytes are in an IPv4 address?

• 128 bits (16 bytes)
• 64 bits (8 bytes)
• 256 bits (32 bytes)
• 32 bits (4 bytes) 

EXPLANATION

IP addresses in Internet Protocol version 4 (IPv4) networking consist of 32 bits (4 bytes).
The address 192.168.0.1, for instance, has values 192, 168, 0 and 1 for each of its bytes. The bits and bytes of that address are encoded like so:

11000000 10101000 00000000 00000001
