Cisco Free 350-401 Exam Sample Questions

Sample Question: 1

Which algorithms are used to secure REST API from brute attacks and minimize the impact?

A. SHA-512 and SHA-384
B. MD5 algorithm-128 and SHA-384
C. SHA-1, SHA-256, and SHA-512
D. PBKDF2, BCrypt, and SCrypt

Answer: D

Explanation:

One of the best practices to secure REST APIs is using password hash. Passwords must always be hashed to protect the system (or minimize the damage) even if it is compromised in some hacking attempts. There are many such hashing algorithms which can prove really effective for password security e.g. PBKDF2, bcrypt and scrypt algorithms. Other ways to secure REST APIs are: Always use HTTPS, Never expose information on URLs (Usernames, passwords, session tokens, and API keys should not appear in the URL), Adding Timestamp in Request, Using OAuth, Input Parameter Validation.

Sample Question: 2

What is used to perform OoS packet classification?

A. the Options field in the Layer 3 header
B. the Type field in the Layer 2 frame
C. the Flags field in the Layer 3 header
D. the TOS field in the Layer 3 header

Answer: D

Explanation:

Type of service, when we talk about PACKET, means layer 3

Sample Question: 3

A. increased MTU size
B. hardware independence
C. VM-level isolation
D. increased flexibility
E. extended 802.1Q VLAN range

A. GLBP
B. HSRP
C. MHSRP
D. VSS
E. VRRP

Answer: A,C

Sample Question: 5

A. SSL
B. MD5
C. AES128
D. AES256

Answer: B

Explanation:

An example of configuring NTP authentication is shown below: Router1(config)#ntp authentication-key 2 md5 itexamanswersRouter1(config)#ntp authenticateRouter1(config)#ntp trusted-key 2

Sample Question: 6

Sample Question: 7

A server running Linux is providing support for virtual machines along with DNS and DHCP services for a small business. Which technology does this represent?

A. container
B. Type 1 hypervisor
C. hardware pass-thru
D. Type 2 hypervisor

Answer: D

Explanation:

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. A 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).

Sample Question: 8

A. 15
B. 1.2
C. -165
D. .83

Answer: A

Sample Question: 9

Under which network conditions is an outbound QoS policy that is applied on a router WAN interface most beneficial?

A. under interface saturation condition
B. under network convergence condition
C. under all network condition
D. under traffic classification and marking conditions.

Answer: A

Sample Question: 10

What is a characteristic of MACsec?

A. 802.1AE provides encryption and authentication services
B. 802.1AE is bult between the host and switch using the MKA protocol, which negotiates encryption keys based on the master session key from a successful 802.1X session
C. 802.1AE is bult between the host and switch using the MKA protocol using keys generated via the Diffie-Hellman algorithm (anonymous encryption mode)
D. 802.1AE is negotiated using Cisco AnyConnect NAM and the SAP protocol

Answer: B

Explanation:

MACsec, defined in 802.1AE, provides MAC-layer encryption over wired networks by using out-of-band methods for encryption keying. The MACsec Key Agreement (MKA) Protocol provides the required session keys and manages the required encryption keys. MKA and MACsec are implemented after successful authentication using the 802.1x Extensible Authentication Protocol (EAP-TLS) or Pre Shared Key (PSK) framework.
