A. Internal EIGRP
B. External EIGRP
C. OSPF
D. ISIS

by: Chris Bryant, CCIE #12933

To help you in your preparation for your Cisco CCNA, CCENT, and CCNP exams, here are some free practice questions covering everything from OSPF to route redistribution. And for you Network+ and Security+ certification candidates, there are questions for you as well on the OSI model and SYN attacks. I'll be adding A+ certification questions in future articles.
Let's get started!

CCENT / Network+ Certification:

To help you in your preparation for your Cisco CCNA, CCENT, and CCNP exams, here are some free practice questions covering everything from EIGRP to the OSI model. And for you Network+ and Security+ certification candidates, there are questions for you as well on the OSI model and teardrop attacks. I’ll be adding A+ certification questions in future articles. Let’s get started!

CCNA 640-802 Exam:

A. bandwidth
B. hop count
C. delay
D. load
E. reliability
F. MTU

Answers: A, C. EIGRP considers bandwidth and delay by default in its route calculations.

Cisco CCENT / CompTIA Network+ Certification:

Which layer of the OSI model is generally recognized as the "management layer"?

Answer: The Session layer.

CompTIA Security+ Certification:

Briefly describe the term "teardrop attack".

Answer: IP fragments with large payloads are the method of attack. Issues with the TCP fragmentation reassembly code of Windows NT, 96, and 3.1x (among others) created this opening.


CCNP Certification / BSCI Exam:

A non-Cisco router will consider what value first during the BGP best path selection process?

A. AS_PATH
B. origin
C. MED
D. weight
E. LOCAL_PREF
F. aggregator

Answer: E. On a Cisco router, weight is the first consideration. However, weight is a Cisco-proprietary BGP attribute. A non-Cisco router will consider LOCAL_PREF first.

CCNP Certification / BCMSN Exam:

Short answer: How can you change the speed and duplex of multiple ports with one command?

Answer: Use the interface range command to configure multiple ports at one time.

A. flood
B. filter
C. unicast
D. drop
E. unicast

Answer: A. The frame will be "flooded" - that is, sent out every port except the one it came in on.

Security+ Certification Exam:

A potential network intruder calls a helpdesk and pretends to be an employee of the company in an attempt to get that employee’s password. What kind of network attack is this?

A. The switch will accept the advertisement.
B. The switch will reject the advertisement.
C. The switch will increment its revision number.
D. The switch will decrement its revision number.

Answers: A, C. The VTP switch will accept the advertisement; since the revision number of the ad is higher than its own, the advertisement is more recent. The switch will then increment its revision number by one.

CCNP Certification / ISCW Exam:

Which of the following queueing methods poses the greatest threat of TCP Global Synchronization?

A. CBWFQ

B. PQ

C. RED

D. WRED

Answer: A. CBWFQ uses Tail Drop as its default method of packet drop. In turn, Tail Drop can lead to TCP Global Synchronization.

Cisco CCNA,CCNP,CCENT,and CompTIA Network+ And Security+ Questions: VLANs,SYN Attacks

Cisco CCNA,CCNP,CCENT,and CompTIA Network+ And Security+ Questions: VLANs,SYN Attacks,And More!
by: Chris Bryant, CCIE #12933

Let’s test your knowledge of important topics such as SYN attacks and VLANs for your Cisco CCNA, CCNP, and CCENT exams, as well as the CompTIA Security+ and Network+ certification exams!

CCNA / CCENT / CompTIA Network+ Certification:

Host A and Host B are in the same VLAN. Host C and Host D are in a different VLAN. Host A sends a broadcast. How many other hosts will receive it?
A. Zero
B. One
C. Two
D. Three

Answer: B. The other host in the same VLAN, Host B, will receive it. Broadcasts are not forwarded to other VLANs.

Security+ Certification:

Briefly describe a "SYN attack".

Answer: The intruder will generate a series of SYN requests, and the soon-to-be-victimized network device sends a SYN-ACK in response. The device then waits for an ACK, but that never comes. These unfinished connections result in the network device not being able to accept SYN request from legitimate network hosts, since its buffers will be overwhelmed with the false (and unfinished) requests.

CCNP Certification / BSCI Exam:

If an IPv6 address begins with "FF", what type of address is it?
A. broadcast
B. unicast
C. multicast
D. MACcast

Answer: C. That's a multicast. There's no such thing as a MACcast. But there should be. ;)

CCNP Certification / BCMSN Exam:

Short answer: What interface-level command takes a port operating at L3 and places it into L2 operating mode?

Answer: switchport. To change the port back to a routed port, use no switchport.

CCNP Certification / ISCW Exam:

Short answer: You're going to write a policy map that will be applied to a Serial interface running at T1 speed. By default, how much bandwidth can you assign in that policy?

Answer: The speed of a T1 line is 1544 kbps, but by default only 75% of that bandwidth can be distributed in a policy map - that's 1158 kbps (1544 * .75).
