Networking Quiz 1

Networking Quiz #1 for some trivia and fun.

1 / 10

1) Which of the options below are Vendor-Neutral Routing Protocols? (Choose 3)

A. OTV

B. OSPF

C. RIP

D. EIGRP

E. BGP

F. Spanning-Tree

G. NTP

RIP, OSPF and BGP are all vendor neutral routing protocols

EIGRP also technically has a vendor neutral flavor; even though I have yet to come into contract with the open standard implementation of EIGRP. Also the non proprietary version of EIGRP is missing some features from the Cisco implementation.

Spanning-Tree and NTP are not routing protocols. OTV is Cisco Proprietary used for overlay routing.

2) At which layer of the OSI model would you find the BGP process operating?

A. Layer 4

B. Layer 3

C. Layer 7

BGP is an application (Layer 7) that uses TCP Port 79 as its transport (Layer 4). The answer I'm looking for here is Layer 7.

3 / 10

3) Out of the box, which attribute will define a root bridge in a multi switch environment?

A. Lowest Base System MAC Address

B. Lowest Physical Uplinked Port

C. Lowest Routing Priority

D. Highest Bridge ID

E. Highest Bridge Priority

The lowest bridge ID will win in this case. The bridge ID = the Default Priority and Base System MAC Address. The default priority in Cisco's Spanning-Tree implementation is set to 32768 + your VLAN ID; so out of the box these values will match between switches. The other component used is the System's Base MAC Address. Since we are in layer 2 territory, the lower the better.

4) True or False.

DHCP Snooping uses the Dynamic ARP Database to verify the DHCP bindings in a switch.

A. True

B. False

Both Dynamic ARP inspection and IP Source Guard rely on the DHCP Snooping Database as their source of truth when evaluating ARPs and IP addressing on a switch.

5 / 10

5) True or False.

A routing table entry of 192.0.2.0/16 is less preferred to an entry of 192.0.2.0/24, when choosing a destination for 192.0.2.1?

A. True

B. False

A longer match in destination routing is preferred within the routing table (in "normal" {not source} routing). So in this example, a /24 (with a mask of 255.255.255.0) would be a longer match than the /16 (with a mask of 255.255.0.0) in attempting to match the destination of 192.0.2.1 (with a prefix mask of 255.255.255.255).

6 / 10

6) Which port security violation mode drops offending traffic as well as generates a log message?

A. Restrict

B. SNMP

C. Shutdown

D. Protect

E. Log

"Restrict mode" will both drop violating traffic and will generate a log message. Protect will not generate a log message.

7 / 10

7) Within which band does 802.11a operate?

A. 900 MHz

B. 5.9 GHz

C. 2.4 GHz

D. 5 GHz

802.11a operates within the 5 GHz band

8 / 10

8) Which DHCP Option would be required to direct a Cisco VoIP phone to a Call Manager System for TFTP?

A. Option 150

B. Option 50

C. Option 42

D. Option 49

Option 150 is used to transfer the phone's config via TFTP.

9 / 10

9) What do the three A’s stand for in AAA? (Choose 3)

A. Asymmetric

B. Accounting

C. Authorization

D. Authentication

E. Authenticated

F. Authorized

AAA stands for Authentication, Authorization and Accounting.

10 / 10

10) Which of the options will stop a broadcast? (Choose 3)

A. ACL Applied to a Layer 3 Switched Virtual Interface (SVI)

B. Layer 3 Switched Virtual Interface (SVI)

C. Port Security

D. Routed Interface

E. L2 Switch Port

F. Firewall in Routed Mode

Broadcasts are frames with a destination MAC Address of all F's (ffff.ffff.ffff, ffff-ffff-ffff, or ff-ff-ff-ff-ff-ff). These frames will flood within the source of the broadcast's local network (VLAN in our case). A Layer 3 Boundary will contain the broadcasts within their VLAN and not allow the propagation across a routed boundary.
