CCNA 200-125 Daily Practice Exam 1: Mixed Topics

Here’s the first in a new series of CCENT and CCNA practice exams!    Five questions at the top, five answers at the bottom.    If you have any questions or comments (or just want to brag about how well you did!), let me hear from you about that via Twitter @ccie12933.

Let’s get started!

Question 1:   The binary string 00100100 converts to which of the following?  Choose two.

A.  Binary value 34

B.  Binary value 36

C.  Binary value 28

D.  Hex value 34

E.  Hex value 24

F.  Hex value 1A

 

Question 2:   When it comes to load balancing in EIGRP, which type(s) are on by default?  Choose one answer.

A.    Equal-cost only.

B.    Unequal-cost only.

C.    Both of these load balancing techniques are enabled by default in EIGRP.

D.    Both types of EIGRP load balancing are off by default.

 

Question 3:    Which two of the following are true of the Hot Standby Routing Protocol?

A.  It’s a Cisco-proprietary protocol.

B.  It’s an industry standard protocol, meaning non-Cisco devices can run it with no trouble.

C.  The MAC address of the HSRP Active router must be manually set.

D.  In HSRP, the MAC address of the Active router is 0000.0C07.ACxx, with “xx” representing the group number in decimal.

E.  The default priority of an HSRP-enabled router is 100.

 

Question 4:    Which one of these physical network devices is associated with the term “microsegmentation”?   Choose one.

A.  router

B.  switch

C.  hub

D.  repeater

E.  wireless router

 

Question 5:    Which one of the following choices best describes the association between OSPF, EIGRP, and their respective hello and dead timers?

A.   Both protocols require a match of hello and dead timers between potential neighbors in order for an adjacency to form.

B.  OSPF requires these two values to match between neighbors, but EIGRP does not.

C.  These values must match between potential EIGRP neighbors, but OSPF couldn’t care less.

D.  Neither protocol considers these values when evaluating a potential adjacency.

And now… the answers!

Answer 1:   B, E.   The binary string  00100100 has the 32 and 4 bits set, giving us the decimal 36.   In turn, the decimal 36 consists of 2 units of 16 and 4 units of 1, resulting in the hex value 24.

Answer 2:   A.   EIGRP’s equal-cost load balancing feature is on by default, but unequal-cost balancing requires the variance command.

Answer 3:   A, E.  HSRP is Cisco-proprietary, and the default priority of an HSRP-enabled router is 100.    Watch that MAC address answer (D) — the MAC address of the Active router is indeed 0000.0c07.ACxx, but the “xx” is the group number in hexadecimal, not decimal. 🙂

Answer 4:  D.  The term microsegmentation refers to the “one port, one collision domain” setup on a switch.

Answer 5:   B.  OSPF requires the hello and dead timers to match between potential neighbors, while EIGRP does not.  You may end up with flapping adjacencies with EIGRP timer mismatches, though, so it’s a good idea to avoid them.

See you tomorrow with a new CCNA practice exam!
