Networking Interview Questions
- In Novell’s use of RIP, there are two metrics used to make routing decisions. Select the two metrics.
* Ticks.
* Hops
* Loops
* Counts
Correct answer: A &B
It first uses ticks (which is about 1/18 sec.); if there is a tie, it uses hops; if hops are equal, then it uses an administratively assigned tiebreaker.
- What is the Cisco name for the encapsulation type used on a serial interface?
* HDLC
* SDLC
* SAP
* SNAP
Correct answer: A
- “arpa” is used by the Cisco IOS for which encapsulation types?
* Ethernet_II
* Ethernet_802.3
* Ethernet_802.2
* Ethernet_SNAP
Correct answer: A
- Novell’s IPX and Cisco’s IOS name their protocols differently. Cisco uses sap for Ethernet_802.2, Token-Ring, and Novell’s FDDI_802.2. Cisco uses snap for Ethernet_SNAP, Token-Ring_SNAP, and FDDI_SNAP. Cisco uses arpa for Ethernet_II and, finally the default is Novell-ether for Novell’s Ethernet_802.3. “snap” is used by the Cisco IOS for which encapsulation types?
* Ethernet_SNAP
* Token-Ring_SNAP
* FDDI_SNAP
* Novell-SNAP
* Novell-FDDI.
Correct answer: A,B &C
- Novell’s IPX and Cisco’s IOS name their protocols differently. Cisco uses sap for Ethernet_802.2, Token-Ring, and Novell’s FDDI_802.2. Cisco uses snap for Ethernet_SNAP, Token-Ring_SNAP, and FDDI_SNAP. Cisco uses arpa for Ethernet_II and, finally the default is Novell-ether for Novell’s Ethernet_802.3.15 “sap” is used by the Cisco IOS for which encapsulation types?
* Ethernet_802.2
* Token-Ring
* FDDI_SNAP
* Ethernet_802.3
* FDDI_802.2
Correct answer: A,B &E
- Novell’s IPX and Cisco’s IOS name their protocols differently. Cisco uses sap for Ethernet_802.2, Token-Ring, and Novell’s FDDI_802.2. Cisco uses snap for Ethernet_SNAP, Token-Ring_SNAP, and FDDI_SNAP. Cisco uses arpa for Ethernet_II and, finally the default is Novell-ether for Novell’s Ethernet_802.3. Which type of Ethernet framing is used for TCP/IP and AppleTalk?
* Ethernet 802.3
* Ethernet 802.2
* Ethernet II
* Ethernet SNAP
Correct answer: D
Ethernet 802.3 is used with NetWare versions 2 through 3.11, Ethernet 802.2 is used with NetWare 3.12 and later plus OSI routing, Ethernet II is used with TCP/IP and DECnet, and Ethernet SNAP is used with TCP/IP and AppleTalk.
- Which type of Ethernet framing is used for TCP/IP and DECnet?
* Ethernet 802.3
* Ethernet 802.2
* Ethernet II
* Ethernet SNAP
Correct answer: C
Ethernet 802.3 is used with NetWare versions 2 through 3.11, Ethernet 802.2 is used with NetWare 3.12 and later plus OSI routing, Ethernet II is used with TCP/IP and DECnet, and Ethernet SNAP is used with TCP/IP and AppleTalk.
- You are a system administrator on a NetWare network, you are running NetWare 4.11 and you cannot communicate with your router. What is the likely problem?
* NetWare 4.11 defaults to 802.2 encapsulation.
* NetWare 4.11 defaults to 802.3 encapsulation
* Cisco routers only work with NetWare 3.11.
* NetWare 3.11 defaults to 802.2 encapsulation.
Correct answer: A
The default encapsulation on Cisco routers is Novell Ethernet_802.3 and NetWare 3.12 and later defaults to 802.2 encapsulation, 3.11 and earlier defaults to 802.3.
- NetWare IPX addressing uses a network number and a node number. Which statements are true?
* The network address is administratively assigned and can be up to 16 hexadecimal digits long.
* The node address is always administratively assigned.
* The node address is usually the MAC address.
* If the MAC address is used as the node address, then IPX eliminates the use of ARP.
Correct answer: A, C &D
The network address can be up to 16 hexadecimal digits in length. The node number is 12 hexadecimal digits. The node address is usually the MAC address. An example IPX address is 4a1d.0000.0c56.de33. The network part is 4a1d. The node part is 0000.0c56.de33. The network number is assigned by the system administrator of the Novell network.
- Which NetWare protocol works on layer 3–network layer—of the OSI model?
* IPX
* NCP
* SPX
* NetBIOS
Correct answer: A
IPX (Internetwork Packet Exchange) is a NetWare network layer 3 protocol used for transferring information on LANs.
