• Question 313:

  What is the correct EBGP path attribute list, ordered from most preferred to the least preferred, that the BGP best-path algorithm uses?

  A. weight. AS path, local preference. MED
  B. weight, local preference AS path, MED
  C. local preference weight AS path, MED
  D. local preference, weight MED, AS path
  B. weight, local preference AS path, MED

  ---

  Explanation

  Path Selection Attributes: Weight > Local Preference > Originate > AS Path > Origin > MED > External > IGP Cost > eBGP Peering > Router ID

• Question 314:

  Which measure is used by an NTP server to indicate its closeness to the authoritative time source?

  A. time zone
  B. hop count
  C. stratum
  D. latency
  C. stratum

  ---

  Explanation

  NTP uses a stratum to describe the distance between a network device and an authoritative time source: A stratum 1 time server is directly attached to an authoritative time source (such as a radio or atomic clock or a GPS time source)

• Question 315:

  A company recently rearranged some users' workspaces and moved several users to different desks. The network administrator receives a report that all of the users who were moved are having connectivity issues. Which of the following is the most likely reason?

  A. Ports are error disabled.
  B. Ports are administratively down.
  C. Ports are having an MDIX issue.
  D. Ports are trunk ports.
  A. Ports are error disabled.

• Question 316:

  Which threat defence mechanism, when deployed at the network perimeter, protects against zero-day attacks?

  A. intrusion prevention
  B. stateful inspection
  C. sandbox
  D. SSL decryption
  C. sandbox

  "File analysis and sandboxing: Secure Malware Analytics' highly secure environment helps you execute, analyze, and test malware behavior to discover previously unknown ZERO-DAY threats. The integration of Secure Malware Analytics' sandboxing technology into Malware Defense results in more dynamic analysis checked against a larger set of behavioral indicators. "

• Question 317:

  Which statement explains why Type 1 hypervisor is considered more efficient than Type 2 hypervisor?

  A. Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS.
  B. Type 1 hypervisor enables other operating systems to run on it.
  C. Type 1 hypervisor relics on the existing OS of the host machine to access CPU, memory, storage, and network resources.
  D. Type 1 hypervisor is the only type of hypervisor that supports hardware acceleration techniques.
  A. Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS.

  ---

  Explanation

  There are two types of hypervisors: type 1 and type 2 hypervisor. In type 1 hypervisor (or native hypervisor), the hypervisor is installed directly on the physical server. Then instances of an operating system (OS) are installed on the hypervisor. Type 1 hypervisor has direct access to the hardware resources. Therefore they are more efficient than hosted architectures. Some examples of type 1 hypervisor are VMware vSphere/ESXi, Oracle VM Server, KVM and Microsoft Hyper-V. In contrast to type 1 hypervisor, a type 2 hypervisor (or hosted hypervisor) runs on top of an operating system and not the physical hardware directly. answer 'Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS' big advantage of Type 2 hypervisors is that management console software is not required. Examples of type 2 hypervisor are VMware Workstation (which can run on Windows, Mac and Linux) or Microsoft Virtual PC (only runs on Windows).

  

• Question 318:

  Refer to the exhibit.

  

  What is achieved by this Python script?

  B. It loads JSON data into an HTTP request.
  C. It reads JSON data into a formatted list.
  D. It converts JSON data to an HTML document.
  C. It reads JSON data into a formatted list.

• Question 319:

  Select the prerequisites for configuring LISP from the below options. (Choose two.)

  A. Determine the type of LISP deployment you intend to deploy
  B. One can directly deploy LISP without determining the type.
  C. LISP configuration requires the datak9 license.
  D. LISP configuration requires the advanced ip services license.
  A. Determine the type of LISP deployment you intend to deploy
  C. LISP configuration requires the datak9 license.

• Question 320:

  Refer to the exhibit. What is displayed when the code is run?

  

  A. The answer is 25
  B. The answer is 70
  C. The answer is 5
  D. The answer is 100
  A. The answer is 25

  ---

  Explanation

  The "magic" function receives a number, which is 5 from main() in this question. This function returns a result of 5 + 2*10 = 25 and the str() function converts it into a string ("25") before printing to the terminal.
