Which of the following is used by the recipient of a digitally signed email to verify the identity of the sender?

  1. Recipient’s private key

  2. Sender’s public key

  3. Recipient’s public key

  4. Sender’s private key

Answer: B Explanation:

When the sender wants to send a message to the receiver. It’s important that this message not be altered. The sender uses the private key to create a digital signature. The message is, in effect, signed with the private key. The sender then sends the message to the receiver. The recipient uses the public key attached to the message to validate the digital signature. If the values match, the receiver knows the message is authentic. Thus the recipient uses the sender’s public key to verify the sender’s identity.

Question No: 233 – (Topic 2)

Results from a vulnerability analysis indicate that all enabled virtual terminals on a router can be accessed using the same password. The company’s network device security policy mandates that at least one virtual terminal have a different password than the other virtual terminals. Which of the following sets of commands would meet this requirement?

  1. line vty 0 6 P@s5W0Rd password line vty 7 Qwer !Y password

  2. line console 0 password password line vty 0 4 password P@s5W0Rd

  3. line vty 0 3 password Qwer !Y line vty 4 password P@s5W0Rd

  4. line vty 0 3 password Qwer !Y line console 0 password P@s5W0Rd

Answer: C Explanation:

The VTY lines are the Virtual Terminal lines of the router, used solely to control inbound Telnet connections. They are virtual, in the sense that they are a function of software – there is no hardware associated with them.

Two numbers follow the keyword VTY because there is more than one VTY line for router access. The default number of lines is five on many Cisco routers. Here, I’m configuring one password for all terminal (VTY) lines. I can specify the actual terminal or VTY line numbers as a range. The syntax that you’ll see most often, vty 0 4, covers all five terminal access lines.

After an assessment, auditors recommended that an application hosting company should contract with additional data providers for redundant high speed Internet connections.

Which of the following is MOST likely the reason for this recommendation? (Select TWO).

  1. To allow load balancing for cloud support

  2. To allow for business continuity if one provider goes out of business

  3. To eliminate a single point of failure

  4. To allow for a hot site in case of disaster

  5. To improve intranet communication speeds

Answer: B,C Explanation:

A high-speed internet connection to a second data provider could be used to keep an up- to-date replicate of the main site. In case of problem on the first site, operation can quickly switch to the second site. This eliminates the single point of failure and allows the business to continue uninterrupted on the second site.

Note: Recovery Time Objective

The recovery time objective (RTO) is the maximum amount of time that a process or service is allowed to be down and the consequences still be considered acceptable. Beyond this time, the break in business continuity is considered to affect the business negatively. The RTO is agreed on during BIA creation.

Question No: 240 – (Topic 2)

A company recently experienced data loss when a server crashed due to a midday power


Which of the following should be used to prevent this from occurring again?

  1. Recovery procedures

  2. EMI shielding

  3. Environmental monitoring

  4. Redundancy

Answer: D Explanation:

Redundancy refers to systems that either are duplicated or fail over to other systems in the event of a malfunction (in this case a power outage). Failover refers to the process of reconstructing a system or switching over to other systems when a failure is detected. In the case of a server, the server switches to a redundant server when a fault is detected.

This strategy allows service to continue uninterrupted until the primary server can be restored.
